Rack safety Rack installation DANGER Observe the following precautions when working on or around your IT rack system: v Heavy equipment—personal injury or equipment damage might result if mishandled. v Always lower the leveling pads on the rack cabinet. v Always install stabilizer brackets on the rack cabinet. v To avoid hazardous conditions due to uneven mechanical loading, always install the heaviest devices in the bottom of the rack cabinet. Always install servers and optional devices starting from the bottom of the rack cabinet. v Rack-mounted devices are not to be used as shelves or work spaces. Do not place objects on top of rack-mounted devices.

v Each rack cabinet might have more than one power cord. Be sure to disconnect all power cords in the rack cabinet when directed to disconnect power during servicing. v Connect all devices installed in a rack cabinet to power devices installed in the same rack cabinet. Do not plug a power cord from a device installed in one rack cabinet into a power device installed in a different rack cabinet. v An electrical outlet that is not correctly wired could place hazardous voltage on the metal parts of the system or the devices that attach to the system. It is the responsibility of the customer to ensure that the outlet is correctly wired and grounded to prevent an electrical shock.

(R001 part 1 of 2) CAUTION: v Do not install a unit in a rack where the internal rack ambient temperatures will exceed the manufacturer’s recommended ambient temperature for all your rack-mounted devices. v Do not install a unit in a rack where the air flow is compromised. Ensure that air flow is not blocked or reduced on any side, front, or back of a unit used for air flow through the unit. v Consideration should be given to the connection of the equipment to the supply circuit so that overloading of the circuits does not compromise the supply wiring or overcurrent protection. To provide the correct power connection to a rack, refer to the rating labels located on the equipment in the rack to determine the total power requirement of the supply circuit. v (For sliding drawers) Do not pull out or install any drawer or feature if the rack stabilizer brackets are not attached to the rack. Do not pull out more than one drawer at a time. The rack might become unstable if you pull out more than one drawer at a time. v (For fixed drawers) This drawer is a fixed drawer and must not be moved for servicing unless specified by the manufacturer. Attempting to move the drawer partially or completely out of the rack might cause the rack to become unstable or cause the drawer to fall out of the rack. (R001 part 2 of 2)

Ethernet Switch s-series Installation and User Guide

Chapter 2. Product Overview This chapter contains an overview of the IBM Ethernet Switch B08S and B16S Layer 2 and Layer 3 switches. Designed for medium to large enterprise backbones, these devices are modular switches that provide the enterprise network with a complete end-to-end Enterprise LAN solution, ranging from the wiring closet to the LAN backbone. Through the remainder of this guide, these products will be referred to as the B08S and the B16S. When reference to a specific model is not required, the general terms switch, product, or device will be used to refer to all the models. The term s-series may also be used to collectively refer to these switch products.

Hardware benefits The s-series switches provide the following benefits: v The management module is non-blocking, with a adjustable switch fabric module and twelve combination Gigabit Ethernet (GbE) copper or fiber ports that provide connectivity to your existing management network. v The management modules have a console port and a 10/100/1000 port that provide connectivity to your existing management network. The management modules optionally support 2-port 10-GbE ports or 8-port GbE fiber and copper ports. v The management modules are interchangeable between the IBM Ethernet Switch s-series models. However, you cannot mix IPv4 and IPv6 modules together in the same chassis. v Optional dual management modules provide 100% redundancy. v The crossbar (xbar) architecture enables the management module to switch 30 Gigabits per second between each interface module and within the management module. v The interface modules and power supplies are interchangeable between the IBM Ethernet Switch s-series models. However, you cannot mix IPv4 and IPv6 modules together in the same chassis. v The management, switch fabric, and interface modules are hot swappable, which means you can remove and replace them while the chassis is powered on and running. v The devices have a passive backplane. v Completely separate data and control planes, which results in uncompromised switching performance, increased reliability of both planes, and increased security of the control plane in the event of a Denial of Service (DoS) attack on the data plane. v Distributed data and control planes, which results in uncompromised wire-speed performance for the data plane and faster and more efficient performance of management functions for the control plane.

Ethernet Switch s-series Installation and User Guide

Power over Ethernet (POE) applications B08S and B16S devices with Power over Ethernet (POE) are compliant with the standards described in the IEEE 802.3af specification for delivering in-line power. The 802.3af specification defines the standard for delivering power over existing network cabling infrastructure, enabling multicast-enabled full streaming audio and video applications for the following converged services: v Voice over IP (VoIP) v WLAN access points v IP surveillance cameras v IP technology devices POE technology eliminates the need for an electrical outlet and dedicated UPS near IP powered devices. With POE power sourcing devices, power is consolidated and centralized in the wiring closets, improving the reliability and resiliency of the network. Because POE can provide power over Ethernet cable, power is continuous, even in the event of a power failure. For POE port density, see “POE port density” on page 4. For more information about POE and how to configure it, see the Configuration Guide.

Support for IPv6 modules The B08S and B16S support IPv6 management and interface modules starting with software release 04.0.00. For details about IPv6 modules, see the following sections in this chapter: v “IPv6 hardware support guidelines” v “Hardware features” v “Interface modules” on page 13

IPv6 hardware support guidelines Note the following guidelines and restrictions with IPv6 Management and Interface modules: v IPv4 interface modules must only be matched with IPv4 management modules and IPv4 interface modules within the same chassis. v If you install dual IPv6 management modules, the modules must be identical. For example, you cannot install one 2-port management module and one 8-port management module together in the same chassis. The modules must be of like-kind.

Hardware features The s-series switches include the following major hardware components: v Chassis v Management module with optional support for dual management modules that provide 100% redundancy v Separate switch fabric modules v Interface modules Chapter 2. Product Overview

Ethernet Switch s-series Installation and User Guide

v Non-POE devices: – The 12-volt AC power supplies (also called system (SYS) power supplies) provide power to one management module and up to eight non-POE interface modules. In the B08S, you can install a second 12-volt power supply for redundancy. The B16S comes with and requires two 12-volt power supplies and supports up to four 12-volt power supplies for redundancy. v POE devices: – The 12-volt AC power supplies (also called system (SYS) power supplies) provide power to the management module, all non-POE interface modules (if applicable), and all ports on POE modules that do not require POE power or to which no power-consuming devices are attached. In the B08S you can install a second 12-volt power supply for redundancy. The B16S comes with and requires two 12-volt power supplies and supports up to four 12-volt power supplies for redundancy. – The 1250 W 48-volt POE power supplies provide power to the POE daughter card, and ultimately to POE power-consuming devices. The number of POE power-consuming devices that one 48-volt power supply can support depends on the number of watts required by each power-consuming device. Each 48-volt power supply can provide a maximum of 1080 watts of POE power, and each POE port supports a maximum of 15.4 watts of power per POE power-consuming device. for example, if each POE power-consuming device attached to the IBM device consumes 15.4 watts of power, one 48-volt supply will power up to 70 POE ports. You can install a second 48-volt supply for additional POE power. – The 48-volt (220-volt input only) POE power supplies provide power to the POE daughter card, and ultimately to POE power-consuming devices. The number of POE power-consuming devices that one 220-volt power supply can support depends on the number of watts required by each power-consuming device. Each 220-volt power supply can provide a maximum of 2160 watts of POE power, and each POE port supports a maximum of 15.4 watts of power per POE power-consuming device. For example, if each POE power-consuming device attached to the device consumes 15.4 watts of power, one 220-volt supply will power up to 140 POE ports. You can install a second 220-volt supply for additional POE power. Note: The system powers on as many POE ports as the 48-volt POE power supplies can handle. The system calculates the maximum number of POE ports it can support based on the number of POE power supplies installed. POE ports are enabled based on their priority settings. Keep in mind that the system will reserve the maximum configured power per POE-enabled port, even if the POE power-consuming device is drawing less power. Attention: The POE power supply is designed exclusively for use with the B08S and B16S devices. The power supply produces extensive power to support 802.3af applications. Installing the power supply in a device other than the ones documented here will cause extensive damage to your equipment. All power supplies are auto-sensing and auto-switching. The power supplies are installed in the slots along the bottom of the chassis. In the B08S the 12-volt (system) power supplies occupy slot numbers 3 and 4 on the right, with the redundant supply in slot 4. The POE power supplies occupy slot numbers 1 and 2 on the left. Figure 11 on page 20 shows power supply placement.

The installed power supplies provide power to all chassis components, sharing the workload equally. If a power supply fails or overheats, the failed power supply’s workload is redistributed to the redundant power supply, if one is present. The power supplies are hot swappable, which means you can remove and replace them without powering down the system. You can remove and insert a power supply without opening the chassis. If the device contains redundant 12-volt power supplies, you can remove one of the power supplies without interrupting operation. The remaining power supply provides enough power for all the ports. For more information about removing and installing the power supplies, see “Installing or replacing a power supply” on page 107. CAUTION: The power supplies are hot swappable, which means they can be removed and replaced while the chassis is powered on and running. However, IBM recommends that you disconnect the power supply from the wall outlet before removing and replacing the supply. The device can be running while a power supply is being installed or removed, but the power supply itself should not be connected to a power source. Otherwise, you could be injured or the power supply or other parts of the device could be damaged.

About replacement power supplies Replacement power supplies for the 90-240 VAC SYS and 90-240 VAC POE, are functionally equivalent to the original power supplies, and can be used in combination with the original power supplies in the same chassis. Although the model numbers for both the newer and older versions of the power supplies are identical, the front of the power supplies are visually different and the manufacturing part numbers are different. The following illustration shows a side-by-side comparison of the 90-240 VAC SYS replacement power supply and the original power supply. The one on the left is the replacement power supply and the one on the right is the original power supply. Figure 13 shows a side-by-side comparison of 90-240 VAC SYS power supplies.

The latching mechanism on the front of the replacement power supplies differ from the latching mechanism on the original power supplies. The latching mechanism protrudes slightly in front, making the power supplies slightly longer in depth. For the actual dimensions, see “Physical dimensions and weight of power supplies” on page 129. Although the model numbers 90-240 VAC SYS for the replacement and original power supplies are identical, the manufacturing part numbers are different, as noted in Table 11 on page 18. The manufacturing part numbers are inscribed on the labels affixed to the top of the power supplies. As well, the manufacturing part numbers for all installed power supplies display in the output of the show chassis command. See “Displaying chassis status and temperature readings” on page 57.

Ethernet Switch s-series Installation and User Guide

About redundant power supplies and power supply failure A chassis with redundant power supplies can maintain full operation when one or more power supplies fail. Power supply failure can be a failure of the supply itself or the office power grid connected to the power supply. A chassis can be either 1 + 1 redundant or N + 1 redundant. 1 + 1 redundancy implies that for every power supply, there is another redundant (backup) power supply. In other words, half of the supplies in the system can fail, and the system will still operate normally. N + 1 redundancy implies that there is one redundant power supply for N power supplies, where N is a number greater than one. for example, 3 + 1 redundancy means that in a system with four power supplies, the system will continue to operate normally if one power supply fails, but will not operate if more than one power supplies fail. Power consumption is equally distributed (within a certain percentage depending on power load or power supply type) among all power supplies in the system. When a power supply fails, the power load is redistributed equally among the remaining power supplies. Note that power consumption between POE and System power supplies is not shared, meaning loss of a System power supply does not impact a POE power supply, and vice versa.

What happens when one or more system power supplies fail If one or more System power supplies fail and the system is left with less than the minimum number of power supplies required for normal operation, the power supplies will go into overload and the system will start to shut down. Several things can happen. The output voltage of the remaining good power supplies will likely drop as they try unsuccessfully to generate more power than they are capable of. The system will react to a drop in voltage by increasing the current draw. The hardware will shut down due to over-current protection or under-voltage protection, whichever takes place first. One by one, the interface modules shut down until the power is within the power budget of the remaining power supplies. There is no particular order in which the interface modules will shut down, as this will occur in hardware and not in software. The management CPU requires power as well, and may also shut down during a power supply failure. After a power loss, if the system is left with less than the minimum number of power supplies required for normal operation, the system will be left in an unknown state. At this point, manual recovery is required (restore power and power-cycle the chassis).

What happens when one or more POE power supplies fail If one or more POE power supplies fail and the system is left with less than the minimum number of POE power supplies, the POE power supplies will go into overload. Non-POE functions will not be impacted, provided the System power supplies are still up and running. Several things can happen with a POE power supply failure. The output voltage of the remaining good power supplies will likely drop as they try unsuccessfully to generate more power than they are capable of. The system will react to a drop in voltage by increasing the current draw. The hardware will shut down POE function due to over-current protection or under-voltage protection, whichever occurs first. The interface modules will start to shut down its POE ports one by one until the over-power is within the power budget of the remaining power supplies. There is no particular order in which the POE ports will shut down, as this occurs in hardware and not in software.

After a power loss, if the system is left with less than the minimum number of power supplies required for normal operation, the system will be left in an unknown state. At this point, manual recovery is required (restore power and power-cycle the chassis).

Cooling system The cooling system is contained within the system’s fan tray assembly and modules. The following components comprise the cooling system: v The B08S each has six fans. v The fans operate at four speeds. v The B16S has two five-speed fans in the rear of the chassis. v One fan control module. The fan control module maintains the power to the fans, and controls the fan speed and the reporting of the fan status to the management module. v Two temperature sensors on each management module, and one temperature sensor on each interface module v One temperature sensor on each switch fabric module (B08S and B16S only). The fan tray in the B08S is located in the right side of each chassis. The B16S has two fan trays which are located in the top rear of the chassis. Upon system startup, the fans operate at low speed, then adjust their speed based on the current temperature of the modules and the configured temperature thresholds, or by the manually configured fan speed. By default, the system polls the temperature sensor on each module every 60 seconds to get a temperature reading. To read additional information about changing the default temperature polling interval, see “Changing the temperature polling interval” on page 68. Depending on the temperature readings for the modules, the system can do the following: v Leave the fan speed at its current setting. v Increase the fan speed. v Decrease the fan speed. v If the chassis exceeds the highest temperature threshold or shutdown temperature for five minutes, the system will shut down the device to prevent damage If the temperature of a module exceeds specified high temperature thresholds, the system generates a Syslog message. The system can also power down the chassis if the temperature exceeds the highest threshold. You can change default low and high temperature thresholds for modules and fan speeds. For more information, see “Changing temperature thresholds for thermal planes and fan speeds on the on the B16S” on page 62. The chassis ships with all fan components fully installed in the fan tray. To read additional information about replacing the fan tray, see one of the following sections: v “Replacing the B08S fan tray” on page 116 v “Replacing the B16S fan assemblies” on page 117

Ethernet Switch s-series Installation and User Guide

Power precautions and warnings CAUTION: The power supplies are ″hot swappable″, which means they can be removed and replaced while the chassis is powered on and running. However, IBM recommends that you disconnect the power supply from the wall outlet before removing and replacing the supply. The device can be running while a power supply is being installed or removed, but the power supply itself should not be connected to a power source. Otherwise, you could be injured or the power supply or other parts of the device could be damaged. Attention: Use a separate branch circuit for each AC power cord, which provides redundancy in case one of the circuits fails. Attention: The POE power supply is designed exclusively for use with the X-Series POE devices. The power supply produces extensive power to support 802.3af applications. Installing the power supply in a device other than the X-Series POE will cause extensive damage to your equipment. Use a separate branch circuit for each AC power cord, which provides redundancy in case one of the circuits fails. Attention: Make sure the power supply is properly inserted in the slot. Never insert the power supply upside down. Attention: Do not attempt to install the power supply without first opening the latch on the front of the power supply. Attempting to install the power supply with a closed latch will result in mechanical damage to the power supply and power supply slot.

Preparing the installation site Cabling infrastructure Note: Ensure that the proper cabling is installed in the site. for information on cabling, see the following sections in this guide: v “Attaching a management station” on page 37 v Chapter 4, “Connecting Network Devices and Checking Connectivity,” on page 45 v “Cable specifications” on page 127.

Installing a chassis in a rack Because of the weight of a fully loaded chassis (97 lbs minimum), IBM recommends mounting a chassis in a rack before installing the modules and power supplies. You can flush mount the B08S using the built-in mounting brackets on the front of the device. Alternatively, you can use the optional rack mount kit to mid-mount the chassis in a rack. The B16S does not have adjustable mounting brackets. To mount the B16S in a rack, you will need to install the brackets in the rack mount kit that ships with the chassis, as shown in Figure 19 on page 32. Before performing this task, you should have an assembled rack and a #2 Phillips-head screwdriver. See “Rack safety” on page xx for precautions when installing equipment in a rack. Each device that you install in a rack, you must provide four mounting screws with which to secure the chassis. To mount the chassis in a rack using the adjustable mounting brackets, do the following: 1. Determine the position of each chassis in the rack. 2. Position two of the four mounting screws for each chassis that you plan to mount in the rack according to the spacings of the keyhole slots on the brackets as shown in Figure 17 on page 31. Do not secure the screws completely; leave approximately 1/4 inch of clearance between the back of the screw head and the rack.

Removing the slot panels The chassis ships with a slot panel installed that covers each empty module slot, ensuring proper airflow within the chassis. If you plan to install a module in a particular slot, you must first remove the slot panel. Attention: If you do not install a module in a slot, you must keep the slot panel in place. If you operate the chassis with an uncovered slot, the system will overheat. Although the slot panels may differ in size, the procedure for removing them from the chassis is the same. The procedure in this section applies to all module slot panels. You need a #2 Phillips-head or flathead screwdriver to perform this task. To remove a slot panel, do the following: 1. Loosen the screws on either end of the slot panel with a #2 Phillips-head or flathead screwdriver. 2. Pull the slot panel out of the chassis, and store it in a safe place for future use.

Although the modules may differ in size and function, the procedure for installing each of them into the chassis is the same. The procedure described in this section applies to all devices. The B08S and B16S management modules are hot swappable, which means you can remove and insert them while the chassis is powered on and running. Notes: 1. The interface modules are interchangeable among the s-series products. However, if you try to install them in chassis other than those documented here, the chassis and interface modules will not function properly. 2. You cannot mix IPv4 and IPv6 modules together in the same chassis. A chassis must either contain all IPv4 management modules and IPv4 interface modules or all IPv6 management modules and IPv6 interface modules. Table 14 provides the chassis slot numbers into which you must install the modules. The following figures show the chassis with slot numbers: v B08S - Figure 2 on page 7. v B16S - Figure 4 on page 9.

Attention: If you do not install a module in a slot, you must leave the slot panel installed in the slot. If you operate the chassis with an uncovered empty slot, the system will overheat. Before installing a module in the chassis, have the following on hand: v An ESD wrist strap with a plug for connection to the ESD connector on the chassis. CAUTION: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor. v A #2 Phillips-head or flathead screwdriver. To install a module in the chassis, do the following: 1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located on the chassis front. 2. Remove the module from its packaging. 3. Insert the management module or the interface module into the appropriate chassis slot and slide the card along the card guide until the ejectors on either side of the module move close to the module front panel. 4. Push the ejectors toward the center of the module to fully seat the module in the backplane. 5. Use the #2 Phillips-head or flathead screwdriver to tighten the two screws at either end of the module front panel.

Ethernet Switch s-series Installation and User Guide

Attaching a management station You can manage the device in the following ways: v You can connect a PC or terminal to the management module’s serial (console) port or 10/100/1000 Ethernet port and access the system directly from the PC or terminal, or from a Telnet connection to the PC or terminal. For more information, see “Attaching a PC or terminal to the console port or 10/100/1000 copper port.” v You can connect the switch to your existing management network and manage the switch, along with other network devices, from a management station. To do this, you can connect a switch to a Gigabit Ethernet port on the management module. For more information, see “Attaching a switch to an Ethernet port” on page 38. Note: The management network into which you can connect a Gigabit Ethernet port must be separate and isolated from the network over which user packets are switched and routed.

Attaching a PC or terminal to the console port or 10/100/1000 copper port The management module’s console port, which has a male DB-9 serial connector, and 10/100/1000 Ethernet copper port(s), which have RJ-45 UTP connectors, allow you to attach a PC or terminal. From the console port, you can access the system’s CLI directly from the PC or terminal or via a Telnet connection to the PC or terminal. From the Ethernet port, you can access the system’s CLI or Web management interface directly from the PC or terminal or via a Telnet connection to the PC or terminal. Before performing this task, you need the following items: v PC running a terminal emulation application or a terminal v If connecting the PC or terminal to the console port, a straight-through EIA/TIA DB-9 serial cable with one end terminated in a female DB-9 connector and the other end terminated in a male or female DB-9 or DB-25 connector, depending on the specifications of your PC or terminal. You can order the serial cable separately from IBM or build your own cable. If you prefer to build your own, see the pinout information in “Serial (console) port pinouts” on page 125. v If connecting the PC or terminal to a Gigabit Ethernet copper port, a category 5 UTP crossover cable, which you must supply. To read additional information about the port pin assignments, see “10/100 and Gigabit port pinouts” on page 126. To attach a PC or terminal to the console port or Gigabit Ethernet copper port, do the following: 1. Connect a PC or terminal to the console port or a 10/100/1000 Ethernet port using the appropriate cable. 2. Open the terminal emulation program, and set the session parameters as follows: v Baud: 9600 bps v Data bits: 8 v Parity: None v Stop bits: 1 Chapter 3. Installing the Chassis

v Flow control: None

Attaching a switch to an Ethernet port The B08S and B16S management module’s 10/100/1000 Ethernet copper port enable you to attach a networking switch. A management station in your existing management network can then access the switch using the IronView Network Manager. For more information, see Chapter 4, “Connecting Network Devices and Checking Connectivity,” on page 45.

Powering on the system After you complete the hardware installation, you can power on the system. Verify that all modules and power supplies are fully and properly installed and no module slots are uncovered. Note the following before powering on the system: Attention: If you do not install a module in a slot, you must keep the slot panel in place. If you run the chassis with an uncovered slot, the system will overheat. Note: The wall outlet should be installed near the equipment and should be easily accessible. Note: The switch is designed to provide uninterrupted service even when you insert or remove the interface modules. Therefore, the system does not have a separate on/off power switch. To turn the system off, unplug the power cord(s).

Connecting AC power to the chassis AC power is supplied though an AC power cord that is installed at the rear of the chassis. 1. At the rear of the chassis, locate the power receptacle where the power supplies have been installed. 2. Lift the cord-retainer and connect the AC power cord to the power supply. 3. Snap the cord-retainer over the power plug to hold it in place, as illustrated below.

Assigning permanent passwords By default, the CLI is not protected by passwords. To secure CLI access, IBM strongly recommends assigning passwords. Note: You cannot assign a password using the Web management interface. You can assign passwords using IronView Network Manager if an enable password for a Super User has been configured on the device. The CLI contains the following access levels: v User EXEC - The level you enter when you first start a CLI session. At this level, you can view some system information but you cannot configure system or port parameters. v Privileged EXEC - This level is also called the Enable level and can be secured by a password. You can perform tasks such as manage files on the flash module, save the system configuration to flash, and clear caches at this level. v CONFIG - The configuration level. This level lets you configure the system’s IP address and configure switching and routing features. To access the CONFIG mode, you must already be logged into the Privileged level of the EXEC mode. You can set the following levels of Enable passwords: v Super User - Allows complete read-and-write access to the system. This is generally for system administrators and is the only password level that allows you to configure passwords. Note: You must set a Super User password before you can set other types of passwords. v Port Configuration - Allows read-and-write access for specific ports but not for global (system-wide) parameters. v Read Only - Allows access to the Privileged EXEC mode and CONFIG mode but only with read access. © Copyright IBM Corp. 2009

45

To set passwords: 1. At the opening CLI prompt, enter the following command to change to the Privileged level of the EXEC mode: FastIron> enable

2. Access the CONFIG level of the CLI by entering the following command: FastIron# configure terminal (config)#

3. Enter the following command to set the super-user password: FastIron(config)# enable super-user-password

4. Enter the following commands to set the port configuration and read-only passwords: FastIron(config)# enable port-config-password FastIron(config)# enable read-only-password

Syntax: enable super-user-password | read-only-password | port-config-password Passwords can be up to 32 characters long.

Configuring IP addresses You must configure at least one IP address using the serial connection to the CLI before you can manage the system using the other management interfaces. In addition, IBM Ethernet routers require an IP subnet address for the subnet in which you plan to place them in your network.

IPv4 devices IPv4 devices support both classical IP network masks (Class A, B, and C subnet masks, and so on) and Classless Inter-domain Routing (CIDR) network prefix masks. v To enter a classical network mask, enter the mask in IP address format. For example, enter: 209.157.22.99 255.255.255.0 for an IP address with a Class-C subnet mask. v To enter a prefix number for a network mask, enter a forward slash ( / ) and the number of bits in the mask immediately after the IP address. for example, enter “209.157.22.99/24” for an IP address that has a network mask with 24 significant (“mask”) bits. By default, the CLI displays network masks in classical IP address format (example: 255.255.255.0). You can change the display to the prefix format. See the Configuration Guide For more information.

IPv4 devices running layer 3 software Before attaching equipment to a router, you must assign an interface IP address to the subnet on which the router will be located. You must use the serial connection to assign the first IP address. for subsequent addresses, you also can use the CLI through Telnet or the Web management interface. By default, you can configure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-interface table. See the Configuration Guide For more information.

5. Set a default gateway address for the switch. FastIron(config)# ip default-gateway 192.22.3.1

Note: You do not need to assign a default gateway address for single subnet networks. Syntax: enable [] Syntax: configure terminal Syntax: [no] ip address or Syntax: [no] ip address / Syntax: ip default-gateway

IPv6 devices IPv6 devices support the 128-bit addressing format, composed of 8 fields of 16-bit hexadecimal values separated by colons (:). For example, 2001:0000:0000:0200:002D:D0FF:FE48:4672 is an IPv6 address, which can also be expressed as 2001:0:0:200:2D:D0FF:FE48:4672 after omitting the leading zeros.

IPv6 devices running Layer 3 software Before attaching equipment to a router, you must assign an interface IP address to the subnet on which the router will be located. You must use the serial connection to assign the first IP address. for subsequent addresses, you also can use the CLI through Telnet or the Web management interface. By default, you can configure up to 24 IP interfaces on each port, virtual interface, and loopback interface. You can increase this amount to up to 64 IP subnet addresses per port by increasing the size of the subnet-per-interface table. See the Configuration Guide For more information.

Connecting network devices These devices support connections to other vendors’ routers, switches, and hubs, as well other IBM devices.

Cable specifications See “Cable specifications” on page 127 for cable lengths and types.

Connecting to Ethernet or fast Ethernet hubs For copper connections to Ethernet hubs, a 10/100Base-TX or 1000Base-T switch, or another IBM device, a crossover cable is required. If the hub is equipped with an uplink port, it will require a straight-through cable instead of a crossover cable. Note: The 802.3ab standard (automatic MDI/MDIX detection) calls for automatic negotiation of the connection between two 1000Base-T ports. Therefore, a crossover cable may not be required; a straight-through cable may work as well. For more information about this feature, see the Configuration Guide. Figure 26 on page 51 shows a UTP crossover cable.

Note: The 802.3ab standard calls for automatic negotiation of the connection between two 1000Base-T ports. Consequently, a crossover cable may not be required; a straight-through cable may work as well.

Connecting to workstations, servers, or routers Straight-through UTP cabling is required for direct UTP attachment to workstations, servers, or routers using network interface cards (NICs). Fiber cabling with LC connectors is required for direct attachment to Gigabit NICs or switches and routers. Note: The 802.3ab standard (automatic MDI/MDIX detection) calls for automatic negotiation of the connection between two 1000Base-T ports. Therefore, a crossover cable may not be required; a straight-through cable may work as well. For more information about this feature, see the Configuration Guide.

Chapter 4. Connecting Network Devices and Checking Connectivity

51

Connecting a network device to a fiber port on the device For direct attachment from the device to a Gigabit NIC, switch, or router, fiber cabling with an LC connector is required. Note: All physical IP interfaces on the Layer 3 devices share the same MAC address. For this reason, if more than one connection is made between two devices, one of which is an s-series Layer 3 device, IBM recommends the use of virtual interfaces. It is not recommended to connect two or more physical IP interfaces between two routers. To connect a device to another network device using a fiber port, you must do the following: 1. Install a fiber optic module (SFP transceiver for Gigabit Ethernet ports, or XFP-MSA transceiver for 10-Gigabit Ethernet ports) 2. Cable the fiber optic module The following sections provide information about performing these tasks.

Installing a fiber optic module You must install a fiber optic module in each Gigabit Ethernet and 10-Gigabit Ethernet fiber port you want to use. Attention: page xiii.

Before beginning any of these procedures, read the “Safety notices” on

Before installing a fiber optic module, have the following on hand: v An ESD wrist strap with a plug for connection to the ESD connector on the chassis. CAUTION: for safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor. To install a fiber optic module into a Gigabit Ethernet or 10-Gigabit Ethernet port, do the following: 1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located in the lower right corner of the chassis front. 2. Remove the module from its protective packaging. 3. If necessary, remove the metal cover from the port on the interface module’s control panel. 4. Gently insert the fiber-optic module into the port until the module clicks into place. The fiber-optic modules are keyed to prevent incorrect insertion.

Cabling a fiber optic module To cable a fiber-optic module, do the following: 1. Remove the protective covering from the fiber optic module and store the covering for future use. 2. Before cabling a fiber optic module, IBM strongly recommends cleaning the cable connectors and the port connectors. For more information, see “Cleaning fiber optic modules” on page 53.

52

Ethernet Switch s-series Installation and User Guide

3. Gently insert the cable connector(s) (a tab on each connector should face upward) into the port connector(s) until the tabs lock into place.

Cleaning fiber optic modules To avoid problems with the connection between the fiber optic module (SFP or XFP) and the fiber cable connectors, IBM strongly recommends cleaning both connectors each time you disconnect and reconnect them. See “Cleaning the fiber optic connectors” on page 91.

Automatic MDI/MDIX detection All 10/100 and Gigabit Ethernet Copper ports on the devices support automatic Media Dependent Interface (MDI) and Media Dependent Interface Crossover (MDIX) detection. This feature is enabled on all 10/100 and Gigabit copper ports by default. For each port, you can disable auto MDI/MDIX, designate the port as an MDI port, or designate the port as an MDIX port. For more information about this feature and how configure it, see the Configuration Guide.

Managing the cooling system This section provides configuration, management, and monitoring information for the cooling system.

Configuring the cooling system The device provides default settings for all cooling system parameters. Therefore, no initial configuration of the cooling system is necessary. If desired, you can change the settings of the following cooling system parameters: v Low and high temperature thresholds for modules and fan speeds v Interval at which the system polls the temperature sensors on the module for a reading v Temperate at which the device will shut itself down v Fan speed

Thermal planes The B08S and B16S have three thermal planes: v Thermal Plane 1 (also called Rule 1/3) - This thermal plane includes the temperature sensors on the management module(s) only. Each management module has two temperature sensors. v Thermal Plane 2 (also called Rule 2/3) - This thermal plane includes all of the temperature sensors on all of the Interface modules. Each Interface module has one temperature sensor. v Thermal Plane 3 (also called Rule 3/3) - This thermal plane includes all of the temperature sensors on the switch fabric modules. Each switch fabric module has one temperature sensor. All thermal planes, along with temperature thresholds, help determine at which speed the fans should operate. For each thermal plane, you can define separate temperature thresholds for fan speeds. Each thermal plane can have different temperature thresholds. For each thermal plane, the device records the highest temperature based on the temperature reading of all of the modules in the thermal plane. The system uses this information and the current configured temperature thresholds to adjust the fan speed. You can view the temperature of each thermal plane using the show chassis command.

Fan speed modes The fans can operate in automatic or manual mode. The default is automatic mode. This section describes both methods. Automatic mode: By default, the fans operate in automatic mode, self-adjusting their speed based on both of the following factors: v the current temperature of each thermal plane v the current configured temperature threshold ranges for all five fan speeds

Chapter 5. Managing the Chassis and Modules

61

The device has default temperature threshold ranges for fan speeds, as shown in Table 19 on page 64. If desired, you can change these settings. The software regularly polls the chassis to obtain the temperature of each thermal plane, then uses this information to decide whether or not to switch the fan speed. By default, the device polls the chassis every 60 seconds for temperature data. You can change this interval using the CLI command chassis poll-time. If the temperature of a thermal plane exceeds the high temperature level of the temperature range associated with the current fan speed in the associated plane, the system will switch the fan speed to the next higher level. for example, let’s say the current fan speed is 3 (medium), and the configured operating temperature range for fan speed 3 is 40 to 50 degrees centigrade for thermal plane 2. Based on this configuration, if the temperature of thermal plane 2 rises to 51 degrees centigrade, the system will automatically increase the fan speed to fan speed 4. Manual mode: Typically, the fans operate in automatic mode, as described above. If desired, you can manually set the speed at which the fans will operate. For more information, see “Manually setting the fan speed” on page 68.

Changing temperature thresholds for thermal planes and fan speeds on the on the B16S The B16S cooling system includes six five-speed fans. The fans operate at speeds of low, medium-low, medium, medium-high, and high. In general, each fan speed, except for low, has a low and high temperature threshold associated with it as shown in Figure 30 on page 63. The low fan speed has a high temperature threshold only.

Figure 30. Fan speeds and temperature thresholds on the B16S

The low and high temperature thresholds enable the device to determine at which speed the fans should operate. In general, the fans operate as follows: v If the temperature of all thermal planes is between the low and high thresholds for a fan speed, the fan continues to operate at that fan speed. v If the temperature of any thermal plane exceeds the high threshold specified for a fan speed, the fan speed increases to the next higher speed. If the temperature of any thermal plane exceeds the high threshold for the high speed and remains above the threshold for five minutes, the system automatically shuts down to prevent damage. v If the temperature of any thermal plane falls below the low threshold for a fan speed, the fan decreases its speed to the next lower speed. If the temperature of any thermal plane falls below the high threshold for the low speed, the fan operates at the low speed. If the temperature of any thermal plane exceeds the high temperature threshold for any of the fan speeds, the software sends a message to the system log. Table 19 on page 64 outlines the default low and high temperature thresholds for each thermal plane and fan speed in the B16S. Note: Table 19 on page 64 applies to the B16S only.

To read additional information about checking the current settings of the low and high temperature thresholds for modules and fan speeds, see “Displaying temperature thresholds for thermal planes and fan speeds” on page 67. Command syntax: If desired, you can change the default low and high temperature thresholds for a particular thermal plane and fan speed. for example, to change the low and high thresholds of the medium fan speed for the management module(s) to 56° C and 72° C, respectively, enter the following command at the global CONFIG level of the CLI: FastIron(config)# fan-threshold mp speed-3 56 72

Syntax: fan-threshold [speed-1 ] [speed-2 ] [speed-3 ] [speed-4 ] for the parameter, you can specify the following: v lp - Changes low and high temperature thresholds for the Interface modules. v mp - Changes low and high temperature thresholds for the management module. v sfp - Changes low and high temperature thresholds for the switch fabric modules. The fan speeds are as follows: v speed-1 - low v speed-2 - medium-low v speed-3 - medium v speed-4 - high (shutdown temperature) For the and parameters, you can specify any temperature in Centigrade. However, when changing low and high temperature thresholds for a module’s fan speeds, remember that the low temperature threshold of a higher fan speed must be lower than the high temperature threshold of the lower fan speed. establishes this guideline to ensure the fan speed stability. For example, if you are changing the temperature thresholds for the management module’s high and medium-high fans speeds, the device will accept the following values because the low temperature threshold for the high speed (67° C) is lower than the high temperature threshold (72° C) for the medium-high speed.

The temperature for the high fan speed (speed-4) is the shutdown temperature. If a thermal plane’s fan-controlled temperature reaches and stays at the shutdown temperature for five minutes, the device will automatically shut down to prevent damage. Displaying temperature thresholds for thermal planes and fan speeds: To check the current settings of the low and high temperature thresholds for thermal planes and fan speeds, enter the show chassis command at any level of the CLI. The following shows an example of the show chassis command output on the B08S. The display is similar on the B16S. This display shows the currently configured temperature thresholds for the management module(s) (Rule 1/3), all of the interface modules (Rule 2/3), and the switch fabric modules (Rule 3/3). # show chassis ... Fan speed switching temperature thresholds: Rule 1/3 (MGMT CARDS THERMAL PLANE): Speed 1: NM57 deg-C Speed 2: 4858 deg-C Speed 3: 4959 deg-C Speed 4: 5080 deg-C (shutdown) Rule 2/3 (LINE CARDS THERMAL PLANE): Speed 1: NM57 deg-C Speed 2: 4858 deg-C Speed 3: 4959 deg-C Speed 4: 5080 deg-C (shutdown) Rule 3/3 (SWITCH FABRIC CARDS THERMAL PLANE)***active***: Speed 1: NM57 deg-C Speed 2: 4858 deg-C Speed 3: 4959 deg-C Speed 4: 5080 deg-C (shutdown)

Syntax: show chassis

Shutdown warning messages If any thermal plane exceeds the shutdown temperature level, the device will display a shutdown warning message on the console every five seconds until either the temperature level goes back down below the shutdown temperature level, or the system shuts down the chassis to prevent further damage (shutdown occurs after five minutes of exceeding the shutdown temperature level). The shutdown warning messages indicate the thermal plane that triggered the warning and the number of seconds before the device will shut down. The following shows an example warning message: !!! Temperature of SWITCH FABRIC CARDS THERMAL PLANE is over shutdown level, system is going to be shutdown in 300 seconds !!!

Chapter 5. Managing the Chassis and Modules

Changing the temperature polling interval By default, the device reads the temperature sensor on each module every 60 seconds. To change the interval at which the system reads the temperature sensors, enter a command such as the following at the global CONFIG level of the CLI: FastIron(config)# chassis poll-time 120

Syntax: chassis poll-time For the parameter, you can specify any number of seconds. If you specify 0, the system reverts to 60 seconds, the default value.

Manually setting the fan speed Note: Use caution when manually setting the fan speed, since this could adversely affect the device’s performance. Typically, the temperature of the thermal planes, in conjunction with the settings of low and high temperature thresholds, determine the speed of the fans. If desired, you can use the fan-speed command to manually set the speed of the fans. For example, to set the speed of all fans to low, enter the following command: FastIron# fan-speed 1

Syntax: fan-speed can be: 1 - low 2 - medium-low 3 - medium 4 - high

Monitoring the cooling system You can monitor the following aspects of the cooling system: v The temperature of the fan control modules v The status and speed of the fans v The temperature warnings sent to the system log

Displaying the temperature By default, the device polls the temperature sensor on each module every 60 seconds to get the temperature of each module. The device records the highest temperature reading of the modules in each thermal plane. The show chassis command displays the temperature reading of each thermal plane, as shown in the following examples. The following shows an example output on the B08S. The output is similar on the B16S.

The speed at which the fan is currently operating (denoted by double brackets). 1 (low) - The fan is functioning at 25 percent of capacity. 2 (medium-low) - The fan is functioning at 37 percent of capacity. 3 (medium) - The fan is functioning at 50 percent of capacity. 4 (high) - The fan is functioning at 100 percent of capacity. NOTE: If the report shows that a fan has failed, the report does not show the fan’s speed.

Displaying temperature warnings If the temperature of a module exceeds the high temperature threshold for any of the fan speeds, the system sends a message to the system log. This section describes how to view the system log. If you have configured the system to use a Syslog server, see the documentation for the server or receiver. To display the system log, enter the following command at any CLI level: # show log ... Dynamic Log Buffer (50 lines):

Syslog logging

The state (enabled or disabled) of the Syslog buffer.

messages dropped

The number of Syslog messages dropped due to user-configured filters. By default, the software logs messages for all Syslog levels. You can disable individual Syslog levels, in which case the software filters out messages at those levels. Each time the software filters out a Syslog message, this counter advances by increments.

flushes

The number of times the Syslog buffer has been cleared by the clear logging command. To read additional information about clearing the Syslog buffer, see “Static and dynamic buffers.”

overruns

The number of times the dynamic log buffer has filled up and been cleared to hold new entries. for example, if the buffer is set for 100 entries, the 101st entry causes an overrun. After that, the 201st entry causes a second overrun.

level

The message levels that are enabled. Each letter represents a message type and is identified by the key (level code) below the value. If you disable logging of a message level, the code for that level is not listed.

messages logged

The total number of messages that have been logged since the software was loaded.

level code

The message levels represented by the one-letter codes.

Static and dynamic buffers The software provides two separate buffers: v Static - logs power supply failures, fan failures, and temperature warning or shutdown messages v Dynamic - logs all other message types In the static log, new messages replace older ones, so only the most recent message is displayed. For example, only the most recent temperature warning

70

message will be present in the log. If multiple temperature warning messages were sent to the log, the latest one will replace the previous one. The static buffer is not configurable. The message types that appear in the static buffer do not appear in the dynamic buffer. The dynamic buffer contains up to the maximum number of messages configured for the buffer (50 by default), then begins removing the oldest messages (at the bottom of the log) to make room for new ones. The static and dynamic buffers are both displayed when you display the log. (config)# show logging ...

When you clear log entries, you can selectively clear the static or dynamic buffer, or you can clear both. for example, to clear only the dynamic buffer, enter the following command at the Privileged EXEC level: # clear logging dynamic-buffer

Syntax: clear logging [dynamic-buffer | static-buffer] You can specify the dynamic-buffer keyword to clear the dynamic buffer or the static-buffer keyword to clear the static buffer. If you do not specify a buffer, both buffers are cleared. Syntax: show log

Syslog messages for PCI (hardware) errors Chassis devices support the display of PCI (hardware) read and write errors encountered on a slot/module during bootup and during normal system operations. There are four types of PCI errors, which may cause the system to disable/power down the module(s) on which they occur: v Configuration read error v Configuration write error v Memory read error v Memory write error For more information, see the Configuration Guide.

Managing the switch fabric modules If desired, you can disable power to a switch fabric module and then reenable it. To disable the power, enter the following command at the Privileged EXEC level of the CLI: # disable switch-fabric 1

Chapter 6. Using a redundant management module You can install a redundant management module in the B08S and B16S. By default, the system considers the module installed in the lower-numbered slot to be the active management module, and the module installed in the higher-numbered slot to be the redundant or standby module. If the active module becomes unavailable, the standby module automatically takes over management of the system. This chapter describes the redundant management module, how it works with the active module, and how to configure and manage it. This chapter provides the following information: v How management module redundancy works v Optional management module redundancy configurations that you can perform v Hitless management features (hitless Layer 2 switchover and hitless Layer 2 OS upgrade) v How to manage and monitor the redundancy feature

How management module redundancy works This section explains the following: v How management module redundancy works under normal operating conditions. v Events that cause a standby management module to assume the role of the active module and how the switchover occurs as a result of each event. v Implications that you should be aware of if a switchover occurs.

Management module redundancy overview When you power on or reload a B08S or B16S with two management modules installed, by default, the management module installed in the lower-numbered slot becomes the active module and the management module in the higher-numbered slot becomes the standby module. (You can change the default active slot using the set-active-mgmt command. To read additional information about performing this task, see “Changing the default active chassis slot” on page 78. After the active and standby modules are determined, both modules boot from the source specified for the active module. The active management module boots from the active management module’s flash memory. After the modules boot, the active module synchronizes the standby module’s flash code and system-config file with its own. During normal operation, the active module handles tasks such as obtaining network topology and reachability information and determining the best paths to known destinations. The active module also monitors the standby module. The standby module functions in an active standby mode. Keeping the system-config and running-config files on both modules synchronized allows the standby module to assume the role of active module seamlessly if necessary. During a switchover, the standby management module takes over the active role and re-initializes all the interface modules in the system that are not CLI-disabled by the administrator. This may cause a brief interruption of the traffic forwarding. © Copyright IBM Corp. 2009

75

Management module switchover The following events cause the standby management module to become the active module, which is called a switchover: v The active module becomes unavailable v You perform a manual switchover v You remove and replace the active management module The following sections explain how the switchover occurs for each event

Unavailable active module The following events cause an active module to become unavailable and a switchover to occur: v An active module experiences a problem significant enough to cause a reset of the module. v The active module loses power. When a switchover occurs, the active module resets itself and sends an interrupt signal to the standby module. The standby module then becomes the active module and the interface modules continue to forward traffic. The new active module begins to manage the system. When the original active module becomes available again or is replaced, it assumes the role of standby module.

Manual switchover In some situations, you may want to manually switch the role of active management module from the currently active module to the standby module. for instance, when you want to remove the current active management module for maintenance. for example, if the module in slot 10 is the active module and the module in slot 9 is the standby module and you want the module in 9 to be the active module and the module in 10 to be the standby module, you can perform a manual switchover using the switch-over-active-role command. To read additional information about performing this task, see “Manually switching over to the standby management module” on page 80. When the switchover occurs, the standby module becomes the active module. Starting in software release 05.0.00, hitless switchover is supported. For more information, see “Layer 2 hitless switchover” on page 83.

Removal and replacement of a management module To read additional information about how to remove and replace a management module, see “Replacing a management module” on page 91. This section explains how management module redundancy is affected when you remove and replace an active or standby management module.

Removal and replacement of an active management module If you remove the active management module, the standby module automatically assumes the role of the active module. After you insert a replacement module in the slot from which the original active module was removed, the replacement module

76

Ethernet Switch s-series Installation and User Guide

becomes the standby module. The module boots from the source specified for the active module. The active management module boots from the active management module’s flash memory. Note: Before removing the active management module, IBM recommends that you first issue the command switch-over-active-role. For details, see “Manually switching over to the standby management module” on page 80. After the replacement module boots, the active module compares the standby module’s flash code and system-config file to its own. If differences exist, the active module synchronizes the standby module’s flash code and system-config file with its own.

Removal and replacement of a standby management module You can remove a standby management module without causing a switchover to occur. The active module continues to function as is. Communication between the active module and the removed module stops until the new module is installed in the chassis. After the new module is installed, it assumes the role of standby module. The module boots from the source specified for the active module. The active management modules boot from the active management module’s flash memory. After the module boots, the active module compares the standby module’s flash code and system-config file to its own. If differences exist, the active module synchronizes the standby module’s flash code and system-config file with its own.

Switchover implications After the role of the active management module switches from one module to another, you must be aware of implications that affect the following areas: v Management sessions v Syslog and SNMP traps v MAC addresses The following sections explain the implications for these areas.

Management sessions You can establish management sessions with the active management module’s management port. If a switchover occurs, the management port on the original active module shuts down and all open CLI, Web management interface, and IronView Network Manager sessions with that port close. You can open new sessions with the new active module, provided that the new active module has the same management port connections. (for example, if you were accessing the Web management interface via a PC connected to the original active module’s management port, you can open a new session if a PC is connected to the new active module’s management port.) In the scenario described above, you can open a new session using the same IP address you were using before the switchover. (You configure an IP address for the active module only; if a switchover occurs, the IP address is used by the new active module.)

Chapter 6. Using a redundant management module

77

Syslog and SNMP traps When a switchover occurs, the system sends a Syslog message to the local Syslog buffer and also to the Syslog server, if you have configured the system to use one. In addition, if you have configured an SNMP trap receiver, the system sends an SNMP trap to the receiver. When the system is powered on or otherwise reset normally, the system sends a cold start message and trap. However, if the system is reset as the result of switchover to the standby management module, the system instead sends a warm start message and trap.

MAC address changes The MAC addresses in the system are based on the MAC address of the chassis. During switchover, the system’s MAC addresses do not change.

Management module redundancy configuration Configuring management module redundancy consists of performing one optional task (changing the default active chassis slot). The section explains how to perform this task.

Changing the default active chassis slot By default, the system considers the module installed in the lower-numbered slot to be the active management module. If desired, you can change the default active chassis slot to the higher-numbered slot. To change the default active chassis slot, enter commands such as the following: # config t (config)# set-active-mgmt mgmt1

Syntax: [no] set-active-mgmt mgmt0 | mgmt1 mgmt0 is the lower-numbered slot and mgmt1 is the higher-numbered slot. To remove the configuration, use the no form of the command. You cannot use the erase startup command to remove the configuration. To view the default active chassis slot currently configured on the device, use the show run command.

Managing management module redundancy The B08S and B16S support the following management tasks related to management module redundancy: v Perform immediate synchronization of files v Perform a manual switchover to the standby module v Reboot the standby module

78

Ethernet Switch s-series Installation and User Guide

File synchronization between the active and standby management modules Each active and standby management module contains the following files that can be synchronized between the two modules: v Flash code - The flash code can include the following files: – Primary - Contains the management module’s primary IronWare image. – Secondary - Contains the management module’s secondary IronWare image. The primary and secondary files also include a monitor file, which contains the management module’s Real Time Operating System (RTOS). The IronWare image contains the layer 1 - 3 software run by the management module. During startup or switchover, the active module automatically synchronizes the standby module’s flash code with its own. Also, when you update the flash code on the active module, the active module automatically synchronizes the standby module’s flash code with its own. v System-config file - The flash code also includes the system-config file. During startup or switchover, the active module compares the standby module’s system-config file to its own. If differences exist, the active module synchronizes the standby module’s system-config file with its own. When you save changes to the system-config file on the active module, the active module automatically synchronizes (without comparison) the standby module’s system-config file with its own. v SSH and SSL keys v Flash file for the DHCP snooping feature Each active and standby management module also includes boot code, which is the code a module runs when it first starts up. The boot code resides in each module’s boot flash. The boot code is synchronized between the two modules. Figure 32 on page 80 shows how the files are synchronized between the active module and the standby module.

Manually switching over to the standby management module This section describes how to manually switch the role of active management module from the currently active module to the standby module. Note: Starting in software release 05.0.00, hitless switchover is supported. An enhancement to the manual switchover feature, a hitless switchover enables a switchover of the active management module to standby module without interrupting switched traffic. For details, see “Layer 2 hitless switchover” on page 83. You can cause the system to switch over to the standby module (and thus make it the active module). To do so, enter the following command: # switch-over-active-role

Once you enter this command, the system will prompt you as follows:

80

Ethernet Switch s-series Installation and User Guide

Are you sure? (enter 'y' or 'n'): y Running Config data has been changed. Do you want to continue the switch-over without saving the running config? (enter 'y' or 'n'): n Please save the running config and try switch-over again

Syntax: switch-over-active role

Rebooting the active and standby management modules You can use the boot system or reload commands to reboot the management modules, maintaining the currently configured active management module (the management module to which the set-active-mgmt command applies). for example, to reboot the active and standby management modules from the primary IronWare image in the management module’s flash memory, enter the following command at the Privileged EXEC level: # boot system flash primary

Syntax: boot system bootp | [flash primary | flash secondary] | slot | tftp The flash primary keyword specifies the primary IronWare image in the management module’s flash memory, while the flash secondary keyword specifies the secondary IronWare image in the flash memory. The tftp keyword directs the switch to boot from an IronWare image on a TFTP server located at with the specified . Note: To reboot the device from a TFTP server through a fiber connection, use the CLI command boot system tftp fiber-port. for example, to reboot the active and standby management modules, enter the following command at the Privileged EXEC level: # reload

Syntax: reload

Hitless management support This section discusses the following Hitless management features supported in software release 05.0.00 and higher: v Layer 2 Hitless Switchover - A CLI-driven switchover of the active and standby management modules without interruption to switched traffic. v Layer 2 Hitless Operating System (OS) Upgrade - An operating system upgrade to software release 05.0.00 or higher, without interruption to switched traffic.

What happens during a hitless OS upgrade and hitless switchover The following describes the internal events that occur during a Layer 2 hitless OS upgrade and hitless switchover: 1. The standby management module resets and reloads with the new software image in its flash memory. 2. The Ethernet interfaces (if present) on the standby module become operational and start carrying data traffic.

Chapter 6. Using a redundant management module

81

3. The active management module synchronizes the standby management module with all the information required to take over the active role. 4. The Layer 2 control protocols on the standby management module converge. This process takes approximately 70 seconds. 5. The standby management module takes over the active role. 6. The old active management module resets and reloads with the same software image running on the current active management module. 7. The switch is now operating on the new software image. The management module that was initially configured as the standby management module is now the active management module and the management module that was initially configured as the active management module is now the standby. Note: The events described above occur internally and do not create or affect the external network topology.

How a hitless OS upgrade and hitless switchover impacts system functions The following table highlights the implications of a hitless OS upgrade or hitless switchover to the system’s major functions. Table 25. Hitless OS upgrade and hitless switchover impacts Traffic Type

Impact

Layer 2 switched traffic, including unicast and multicast

Layer 2 switched traffic is not impacted during a manual switchover. All existing switched traffic flows continue uninterrupted. New switched flows are not learned by the switch during the switchover process and are flooded to the VLAN members in hardware. After the new active management module becomes operational, new switched flows are learned and forwarded accordingly. The Layer 2 control protocol states are not interrupted during the switchover process.

Layer 3 routed traffic, including unicast and multicast

Layer 3 routed traffic is briefly interrupted during the manual switchover process. The traffic will converge to normalcy after the new active CPU becomes operational.

Management traffic

All existing management sessions (SNMP, TELNET, HTTP, HTTPS, FTP, TFTP, SSH etc.), are briefly interrupted during the switchover process. All such sessions are terminated and can be re-established after the new active CPU takes over.

Security features

All security features other than configured ACLs are not hitless. Configured ACLs will continue to operate in a hitless manner, meaning the system will continue to permit and deny traffic during the switchover process. All other security features are briefly interrupted during the switchover process and will return to normalcy after the new active management module is operational.

Note: All traffic going through Ethernet interfaces (if present) on the management modules will be interrupted during a hitless OS upgrade. This is because

82

Ethernet Switch s-series Installation and User Guide

both management modules must be reloaded with the new image. This applies to hitless OS upgrade only. It does not apply to hitless switchover, which does not interrupt traffic going through Ethernet interfaces on the management modules. Note: Static and dynamic multi-slot trunks will flap during a hitless switchover if any of the trunk port members are on the management module.

Syslog message for hitless OS upgrade and hitless switchover The following Syslog message is generated as a result of a switchover during a hitless OS upgrade or hitless switchover: HITLESS-RELOAD COMPLETED - Mgmt Module in slot is now Active

Layer 2 hitless switchover Platform Support: B08S and B16S chassis devices running software release 05.0.00 and later - L2, BL3, L3 Hitless switchover is a CLI-driven switchover of the active and standby management modules without interruption to switched traffic. In software releases that do not support hitless switchover (pre-release 05.0.00), a manual switchover impacts the data traffic for the duration of the switchover and requires data flows to be relearned. This feature can be used by a system administrator, for example, to perform maintenance on a management module that has been functioning as the active management module. The Layer 2 functions and protocols supported by hitless switchover are the same as those supported for hitless OS upgrade see “Layer 2 hitless OS upgrade” on page 84for a list. Some advantages of a hitless switchover over a hitless software reload are: v A manual switchover is quicker, since the standby module does not have to reboot. v Switched traffic through the Ethernet interfaces on the standby management module is not interrupted. Note: If the current active management module is physically removed from the chassis without first issuing the switch-over-active-role command, the standby module will still take over the active role, but the chassis will reset and re-initialize all components. Thus, traffic going through the system will be interrupted. For a description of the events that occur during a hitless switchover, see “What happens during a hitless OS upgrade and hitless switchover” on page 81. For a description this feature’s impact to major system functions, see “How a hitless OS upgrade and hitless switchover impacts system functions” on page 82.

Executing a Layer 2 hitless switchover The CLI command for executing a hitless switchover is the same as for a switchover (non-hitless) in software releases prior to 05.0.00. See “Manually switching over to the standby management module” on page 80.

Layer 2 hitless OS upgrade Platform Support: B08S and B16S chassis devices running software release 05.0.00 and later - L2, BL3, L3 Layer 2 Hitless OS upgrade enables an upgrade of the operating system on a switch that has redundant management modules, to software release 05.0.00 or higher, without interrupting switched traffic for the following Layer 2 features and protocols: Table 26.

Note: Layer 2 services and protocols that are not listed (not supported by the hitless feature) may encounter disruptions during reset of the management and interface modules, but will resume normal operation once the modules are back up and running. Note: See also “How a hitless OS upgrade and hitless switchover impacts system functions” on page 82.

Configuration considerations Consider the following when using the Layer 2 hitless OS upgrade feature: v For a description of the events that occur during a hitless OS upgrade, see “What happens during a hitless OS upgrade and hitless switchover” on page 81. v For a description of how this feature impacts major system functions, see “How a hitless OS upgrade and hitless switchover impacts system functions” on page 82. v You must have both active and standby management modules installed to use this feature. v Hitless OS upgrade is supported in software release 05.0.00 or higher, with boot image 05.0.00 or higher. v Hitless OS upgrade between different types of software images is not supported. for example, hitless OS upgrade is supported when upgrading the Layer 2 image to another Layer 2 image. It is not supported when upgrading the Layer 2 image to a Layer 3 image, or the base Layer 3 image to a full Layer 3 image, and so forth. v Hitless OS upgrade should be performed locally, since remote connectivity will be lost during the upgrade. During a reload, HTTP, SSH, Telnet, SNMP, and ping sessions will be dropped. v The active management module switches from the initial active management module to the standby management module during the hitless upgrade process. Therefore, a connection to the console interface on both management modules is required.

Chapter 6. Using a redundant management module

85

v Upon being reset, traffic going through the ports (if present) on the management module will be interrupted. Once the management module is up and running, it will be able to send and receive packets, even before the hitless upgrade process is complete. v The Layer 3 router configuration is not allowed to be changed any time during the hitless upgrade process. v System-max configuration changes require a system reload. System-max configuration changes do not take effect by the hitless upgrade. Even if a system-max parameter is changed and saved in the startup configuration, the switch will revert to the default system-max value upon a hitless software upgrade. The new system-max value will only take effect after a regular system reload. v Other commands requiring a software reload also do not take effect upon hitless upgrade and require a system reload before being placed in effect. v This feature can be used to upgrade an image to a higher or lower compatible version of the software, even if the software image does not support hitless upgrade. However, if hitless upgrade is not supported, the upgrade process will not be hitless, and the entire system will reload upon upgrading to the software image. v The Layer 2/Layer 3 hitless failover feature is not supported in this release. v The Layer 3 hitless upgrade feature is not supported in this release.

Configuration steps The following is a summary of the configuration steps for a Layer 2 hitless OS software upgrade: 1. The software image that supports Layer 2 hitless software upgrade is copied from a TFTP server to the switch. See “Loading the software onto the switch.” 2. The software image is installed in flash memory on the active and standby management modules. 3. The hitless-reload command is entered on the active management module. The command triggers the events described in the section “What happens during a hitless OS upgrade and hitless switchover” on page 81.

Loading the software onto the switch Hitless OS upgrade loads from the primary and secondary images on the management modules. To perform the hitless upgrade, you must first copy the software image that supports Layer 2 hitless software upgrade onto the flash memory of the active and standby management modules. for instructions for copying these files, see the release notes or the Configuration Guide.

Executing the hitless-reload command After loading the software image onto the flash memory of the active and standby management modules, you can begin the process of performing a hitless OS upgrade using the hitless-reload command. for example: #hitless-reload primary

Syntax: hitless-reload primary | secondary The primary parameter specifies that the management module will be reloaded with the primary image.

86

Ethernet Switch s-series Installation and User Guide

The secondary parameter specifies that the management module will be reloaded with the secondary image.

Verifying the new software image Enter the show version command at any CLI level to verify that all management and interface modules are running the new software image version.

Monitoring management module redundancy You can monitor the following aspects of management module redundancy: v The status of the management modules (if a module is the active or standby module) v The switchover history for the management modules The following sections explain how you can monitor the management modules

Determining management module status You can determine the status of a management module in the following ways: v LEDs - The LEDs on the management module indicate whether a module is the active module or the standby module, and if the module has power. v Redundant management and module information in software - The module information displayed by the software indicates whether a module is the active module or the standby module.

Status LED If you are located near the chassis, you can determine which management module is currently the active module and which is the standby module by observing the Active LED on each module. If this LED is on (green), the module is the active module. If this LED is off, the module is the standby module. You can also observe the Pwr LED on each module. If this LED is on (green), the module is receiving power. If this LED is off, the module is not receiving power. (A module without power will not function as the active or standby module.)

Software You can use the show module CLI command to display the status of the management modules: The following shows an example output of the show module command.

Syntax: show module The Status column indicates the module status. The management modules can have one of the following statuses: v ACTIVE - The module is currently the active management module. v STANDBY - The module is the standby management module. The status of the standby module can be one of the following: – Init - The module is currently initializing as the standby module. – OK - The module is ready to take over as the active module, if necessary. – Wait - The module is awaiting boot information from the active management module. – Sync - The active module is currently synchronizing files between itself and the standby module.

Displaying temperature information Each management module contains two temperature sensors. By default, the system polls the temperature of each management module every 60 seconds. You can display the current temperature of the management modules (and all other modules) by entering the following command at any CLI level: # show chassis ... Slot 9 Temperature: 31.0 deg-C Slot 10 Temperature: 34.0 deg-C

Syntax: show chassis The output displays the temperature of the management modules. To read additional information about all output generated by the show chassis command, see “Displaying chassis status and temperature readings” on page 57.

Chapter 7. Maintaining the hardware This chapter provides instructions for maintaining the hardware. See the “Safety notices” on page xiii before starting any of these procedures. CAUTION: Servicing of this product or unit is to be performed by trained service personnel only. (C032)

Hardware maintenance schedule The chassis requires minimal maintenance for its hardware components. IBM recommends cleaning the fiber-optic connectors on a fiber-optic port and the connected fiber cable each time you disconnect the cable. Otherwise, you can replace the following hardware components as needed: v Management and interface modules v Switch fabric modules v POE daughter card v Copper and fiber optic modules (SFPs and XFP transceivers) v Power supplies v Fan tray v Blowers

Cleaning the fiber optic connectors To avoid problems with the connection between the fiber optic module (SFP or XFP) and the fiber cable connectors, IBM strongly recommends cleaning both connectors each time you disconnect and reconnect them. In particular, dust can accumulate in the connectors and cause problems such as reducing the optic launch power. To clean the fiber cable connectors, IBM recommends using the fiber-optic reel-type cleaner that shipped with your chassis. When not using an SFP or XFP connector, make sure to keep the protective covering on it.

v If your chassis has redundant management modules, you can remove one of the management modules from the chassis while the chassis is powered on and running. This does not apply to the B08S and B16S with single management modules. These devices must be powered down before removing the management module. v If your device does not have dual management modules, do not remove the management module while the chassis is powered on and running. If you attempt to remove this module while the chassis is powered on and running, all traffic being handled by the system will stop. v Before removing and replacing an active or standby management module, you need to understand how these actions affect management module redundancy. See “Removal and replacement of a management module” on page 76. v You cannot mix IPv4 and IPv6 modules together in the same device. IPv4 interface modules must only be matched with IPv4 management modules and IPv4 interface modules within the same chassis.

Removing a management module Before removing a management module, have the following tools on hand: v An ESD wrist strap with a plug for connection to the ESD connector on the chassis. CAUTION: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor. v A #2 Phillips-head or flathead screwdriver. To remove a management module from the chassis, do the following: 1. See “Safety notices” on page xiii. 2. If your chassis does not have redundant management modules, power down the chassis and remove the power cables from the chassis power supplies. 3. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located on the chassis front. 4. Use a #2 Phillips-head or flathead screwdriver to loosen and remove the two screws on the ends of the module. 5. Pull the card ejectors towards you, and away from the module front panel. This action unseats the module from the backplane. 6. Pull the module out of the chassis, and place in an anti-static bag for storage if desired. 7. Install a new module in the slot.

Replacing an interface module You can remove an interface module and replace it with a new one while the B08S and B16S is powered on and running. This section provides information about the following tasks: v General precautions v Removing an interface module v Installing a new interface module

Precautions Note the following when removing and replacing interface modules: v If you remove an interface module without first disabling it, the chassis will reboot (reload the software). v You do not need to enable an interface module after inserting it in the chassis. The device automatically enables the module when you insert it into a live chassis or when you power on the chassis. v You cannot mix IPv4 and IPv6 modules together in the same device. v The software does not allow simultaneous insertion of multiple interface modules. After inserting an interface module, wait a few seconds before inserting the next module. If you attempt to insert modules one right after the other, the system will display an error message. v If you plan to replace the removed module with a different type of module, you must remove the module configuration. To do so, enter the no module command at the global CONFIG level of the CLI. If you attempt to insert a module of a different type without first removing the previous module configuration, the system will display an error message.

Before removing an interface module Before removing an interface module, you must have the following on hand: v An ESD wrist strap with a plug for connection to the ESD connector on the chassis. CAUTION: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor. v A #2 Phillips-head or flathead screwdriver. Disable the module by entering the disable module command at the Privileged EXEC level of the CLI. For the parameter, specify a valid slot number. v Figure 2 on page 7 displays the slot numbers on the B08S. v Figure 4 on page 9 displays the slot numbers on the B16S. If you remove an interface module without first disabling it, the chassis will reboot (reload the software).

Chapter 7. Maintaining the hardware

97

Attention: v These devices support the ″enhanced hot swap″ feature. The disable module command before removing an interface module is not required, but is recommended. v It is recommended that modules be disabled through the CLI before removal from the chassis. If the operator wishes to remove the module without first disabling the module, the Enhanced Hot Swap capability supports this procedure for the B08S and B16S chassis. Enhanced Hot Swap (that is, no CLI disable) should be performed during a maintenance window. On rare occasions, an Enhanced Hot Swap may result in a software reload of the system. The likelihood of this event is very low. It is important to wait a minimum of 10 seconds between the removal and insertion of a line module. Re-insertion of a line module less than 10 seconds after the removal of a line module may result in the line module not being properly recognized.

Removing an interface module Perform the steps in the section “Before removing an interface module” on page 97, then do the following: 1. Put on the ESD wrist strap and ground yourself by inserting the plug into the ESD connector located in the lower right corner of the chassis front. 2. Use the #2 Phillips-head or flathead screwdriver to loosen the two screws on the ends of the module. 3. Pull the card ejectors towards you, and away from the module front panel. This action unseats the module from the backplane. 4. Pull the module out of the chassis, and place in an anti-static bag for storage if desired. 5. If you plan to replace the removed module with a different type of module, you must first remove the module configuration. To do so, enter the no module command at the global CONFIG level of the CLI, then save the configuration to flash memory. For example: (config)# no module 4 (config)# exit # write mem

Note: If you attempt to insert a module of a different type without first removing the previous module configuration, the system will display an error message. 6. Install a new module in the slot. To read additional information about performing this task, see “Installing a new interface module.” Attention: If you do not install a module in a slot, you must keep the slot panel in place. If you run the chassis with an uncovered slot, the system will overheat.

Installing a new interface module You can install an interface module in the B08S and B16S while the chassis is powered on and running. Before installing one of these modules into the chassis, have the following on hand: v A new interface module v An ESD wrist strap with a plug for connection to the ESD connector on the chassis.

98

Ethernet Switch s-series Installation and User Guide

Configuring a LAN/WAN PHY interface module WAN PHY enables a 10 Gbps Ethernet port to use SONET/SDH for Layer 1 transport, thus allowing for the extension of Ethernet links across a WAN transport backbone. The following sections contain instructions for configuring the LAN/WAN PHY module.

Enabling the LAN/WAN PHY module To enable a LAN/WAN PHY module after installing it, enter a command such as the following: (config)#module 6 fi-sx4-2-port-10g-lan-wan-module

Syntax: module fi-sx4-2-port-10g-lan-wan-module where is the slot number where the LAN/WAN PHY module is installed.

Setting the WAN PHY mode A 10 Gbps Ethernet port on a LAN/WAN PHY module can be set up for either WAN or LAN mode. The default state is LAN mode. The link-config x10g wan-phy command allows you to change to WAN mode from LAN mode. Note: This command is supported on the LAN/WAN PHY module only. EXAMPLE:

To enable the WAN PHY mode, enter commands such as the following: (config)# link-config x10g wan-phy e 1/1 e 1/2 (config)# write memory (config)# end # reload

These commands change the PHY mode from LAN to WAN. Note: The write memory and reload commands save the change to the startup-config file and place the WAN PHY configuration in effect. Syntax: link-config x10g wan-phy ethernet where is a valid 10-Gigabit Ethernet port or ports.

Disabling and re-enabling an interface module Note: This section does not apply to the active management module. The disable module and enable module commands are not applicable to the active management module. If you attempt to remove the management module while the chassis is powered on and running, all traffic being handled by the system will stop. Before removing an interface module from the chassis while the chassis is powered on and running, disable the module first. Disabling the module before removing it prevents a brief service interruption on other forwarding modules. The brief Chapter 7. Maintaining the hardware

101

interruption can be caused by the chassis re-initializing other modules in the chassis when you remove an enabled module. To disable a module, enter a command such as the following at the Privileged EXEC level of the CLI: # disable module 3

This command disables the module in slot 3. Syntax: disable module The parameter specifies a valid slot number. If you decide after disabling a module that you do not want to remove the module, re-enable the module using the following command: # enable module 3

Syntax: enable module

Installing or replacing a POE daughter card This section provides instructions for installing or replacing a Power Over Ethernet (POE) daughter card in the chassis. The POE daughter card enables support for POE power-consuming devices. The card is located in a connector slot on the 24-port Gigabit Ethernet copper interface module. You can install or replace a POE daughter card while the chassis is powered on and running. Before installing or replacing the card, disable the module to prevent the remaining interface modules in the chassis from dropping user packets. Note: If applicable, install a 48-volt POE power supply prior to installing the POE daughter card. The system will not recognize the POE daughter card unless there is a POE power supply operating in the chassis. See “Installing or replacing a power supply” on page 107. To perform this task, you must have the following on hand: v A POE daughter card. v An ESD wrist strap with a plug for connection to the ESD connector on the chassis. CAUTION: For safety reasons, the ESD wrist strap should contain a series 1 meg ohm resistor. v A #2 Phillips-head or flathead screwdriver. To replace or install the POE daughter card, do the following: 1. Disable the 24-port Gigabit Ethernet module for which you will replace or install the POE daughter card. Enter a command such as the following at the Privileged EXEC level of the CLI: # disable module 1
