APPLICATIONS DRIVING POWER OVER ETHERNET Convergence of IP telephony (Voice over IP), wireless access points, IP security cameras and advanced intelligent building applications necessitate reliable, flexible and scalable powering solutions. PoE provides flexibility of device placement and enables a single common RJ45 connection to support both data and power.

IP Telephony IT managers must ensure that new IP telephony systems can be continuously powered and provide similar uptime to that expected from traditional telephone networks. Traditional enterprise data systems utilize Uninterruptible Power Supplies (UPS), which in the event of a power failure allow sufficient time for critical operations, databases, and servers to shut down according to established operational procedures. This backup time is typically measured in minutes or quarter hours of standby time. DC powered systems are connected in parallel to transparently charge and provide power without switchover delays.

IP Security With the acceptance of hard disk based recording devices and IP multicast solutions, security systems no longer require proprietary hardware and software. IP security cameras with PoE connections provide the widest range of deployment options. By eliminating the need to run separate power lines to specific locations, flexibility is improved and installation costs are reduced. Additionally, centralized monitoring and maintenance can be achieved locally or remotely utilizing the IP data stream (for camera resets and recalibration).

Wireless Wireless installations have progressed from simple points of convenience to support of mission critical applications. Laptop computers and wireless IP handsets require seamless operations across enterprise, campus, and retail environments. PoE allows wireless access points to be positioned for optimum coverage. By eliminating the additional expense of running electrical lines to specific locations, the overall cost of installation is greatly reduced and design flexibility enhanced. Remote management of the wireless system is simplified since the wireless access point can be powered down during off-hours, thus maintaining security. Remote resets of the wireless access points can also be performed to facilitate upgrades of endpoint devices. Therefore, PoE provides improved security and maintenance.

Lighting System

Structured network UTP cabling and IP protocols provide an integrated view and a common platform between the various building systems. PoE provides a unified power system and backup provisions for critical building functions without any additional cables, outlets or connections. The powering standard specified by the IEEE 802.3af standard supports 48 volts DC as a regulated supply across all platforms, so that modularity and the cost of backup powering can be shared across multiple building functions.

Power over Ethernet Standards The telecommunications industry was built around 48 volts powering standards. IEEE 802.3af is the first international standard to define the transmission of Power over Ethernet. This standard is based on existing category 5 infrastructures as a baseline requirement to support: (1) voltage supply between 44 and 57 volts DC; (2) 350 – 400 milliamperes; and (3) 15.4 watts of power at the source. Category 5 (and higher) Ethernet cabling is capable of supporting these devices in today's infrastructure up to 100 meters (90 meter horizontal + 10 meter patch field).

BENEFITS OF THE PANDUIT MANAGED POWER SOLUTION PANDUIT has taken an innovative approach toward providing a PoE solution that is scalable and ensures ample powering for IEEE 802.3af and Cisco legacy devices for maximum interoperability. Additionally, by maintaining a DC powering infrastructure, the DPoE ™ Power Patch Panel dissipates less heat compared to solutions which utilize direct AC inputs requiring power conversion.

DPoE ™ Power Patch Panels High Density – Compact 24-port power patch panel design combines patching and PoE in a single device occupying only one rack space; provides lower total cost of ownership compared to conventional midspan devices. Optimized Performance – Supports 48 volt DC IEEE 802.3af-2003 and Cisco power schemes that automatically sense and provide proper powering for connected devices; eliminates the need to install separate power modules per port to save space, provides network design flexibility, and lowers overall cost of installation and peripheral components. Power – Supports 15.4 watts to every port, which eliminates power budget load balancing, providing greater design flexibility as PoE devices share power across all 24 ports. Low Heat Dissipation – Dissipates approximately 5 watts or about 17 BTUs of heat per unit, which is roughly 15 times lower than the BTU output of comparable network equipment. There is minimal power dissipation in the DPoE ™ panel, so panels can be mounted directly on top of each other in a rack configuration.

DPoE ™ Element Manager Software (included with the Power Patch Panel) Local Manageability – Allows devices to be powered on or off via SNMP/V2 control; eliminates the need to dispatch technicians to power cycle devices reducing the total operating cost of a PoE system. Remote Manageability – Provides visibility of all powered ports across the network and allows multiple site management with a single graphical user interface resulting in lower total cost of ownership.

DPoE ™ Power Systems The DPoE ™ Power Patch Panel is ready to directly connect to 110V/220V AC or through an uninterruptible power supply (UPS) system using the DPoE ™ Power System. The DPoE ™ Power System utilizes high efficiency power supplies (>92%) that can be hot-swapped for field upgrades or for replacement without taking the entire system down. Space Saving – Low profile, 1 RU size saves rack space compared to traditional 48 Volt power sources. Low Heat Dissipation – Emits 35% less heat compared to other power supply systems. Increased Reliability – Individual and replaceable fuses provide safe powering of up to 14 individual DPoE ™ Power Patch Panels from a single power chassis. In the event of a fault, problem isolation is reduced to a single patch panel vs. the entire system. Upgradeability – A network interface option allows for intelligent power monitoring and provides an upgrade path for extended features and services including direct battery management, voltage regulation, and alarming. Scalability – The 48 volt DC power is scalable from 500 to 3,750 watts and provides consistent powering across a wide range of devices and application needs.

DPoE ™ Power Supply For lower port-count needs, the DPoE ™ Power Supply connects directly to a single DPoE ™ Power Patch Panel. Space Saving – Flexible placement inside of rack unit allows the power supply to be located anywhere within a 10 foot reach of the power patch panel. Low Heat Dissipation – The isolated power supply removes any heat due to AC to DC power conversion from the power patch panel while providing up to 120 watts of regulated power. Status LED – A status LED indicates when power is being supplied to the panel.

MID VS. PANEL DISCUSSION

DESIGNING YOUR POWER OVER ETHERNET SYSTEM When deploying PoE technology, IT Managers and Network Managers must consider the demands placed on space, power backup, cooling, management and scalability of the entire solution.

Real Estate and Rack Space Requirements How much space should be allotted for power systems? Every rack unit allotted for powering takes away space from network devices, connections, and services. In organizations where data center and telecommunication room real estate is at a premium, the installed cost of a single 1 RU of rack space can be very expensive. When evaluating space requirements for your network consider the following midspan vs. panel example below:

• All intermediate devices installed between the switching equipment and the patch panel, terminating the horizontal cabling, add to the space (and cost) equation and lower the overall channel performance • All intermediate devices will require additional patch cords for connectivity and will necessitate additional space for management of the additional cables • Horizontal or vertical cable management must be budgeted when looking at the overall space requirements

Power Back-Up – AC vs. DC Backup Supplies Emergency backup in the form of an Uninterruptible Power Supply (UPS) is required for high-reliability applications such as IP telephony, wireless, and security systems. In a centralized power approach, backup systems are located in a telecommunications room or data center. Centralized power cost effectively offers improved management while maintaining maximum uptime.

Typical Example: Consider a system with 240 PoE ports. Allocating 15.4 watts per port (according to the IEEE specification) would require a power source capable of supplying about 4,000 watts. Operational costs can be broken out into the following items: The commercial cost of power (e.g., $0.15/kW-hr) • 1.1 kW x $0.15/kW x 365 days x 24 hr = $1,445 per year The cost of cooling (air conditioning – both lifecycle and initial cost) Heat is an enemy to electronic equipment, and lowers the lifespan of mission critical data equipment. Airflow planning is required to eliminate hot spots and ensure proper dissipation of hot air from active electronics. Power consumption must be calculated as new PoE equipment is installed. If power consumption exceeds the capacity of the existing infrastructure, costly upgrades are required. The PANDUIT ® DPoE ™ system is engineered for low heat and power consumption. • 1.1 kW = 3754 BTU/hr = 0.31 ton air conditioner assuming an AC unit (EER = 8.5) = $310/year

Total savings per year = $1,755 (which equates to about $175 savings per panel per year)!

Power Management and Connectivity Enterprise managers are concerned with the number of active ports that can be powered and supported. How does an organization know if sufficient power is being supplied to each client? How does one manage the power budget? The ability to know and understand the effect of adding devices to the network before they are added is critical information for network planning. Addressing power as a managed utility provides the added benefit of separating data tasks from utility driven needs. For example, by being alerted that a device is no longer receiving or drawing power, a network manager may proactively take corrective action before costly downtime is even recognized in a network. This is especially true in a call center environment where every call attendant represents allocated costs and potential lost revenue if calls are not being taken. In addition to monitoring the power connectivity of endpoint devices, PANDUIT Element Management System offers the ability to remotely turn devices on and off by addressing the individual port or via the device naming capability. A practical usage is realized when devices need to be reset, either because the device is being reconfigured or to accept a new software download and needs to be restarted. Rather than sending a technical or facilities engineer to restart the device, the network manager simply needs to click on the associated port and issue the appropriate ON/OFF command resulting in reduced execution time and cost savings.

Scalability of Power over Ethernet Systems The ability to increase the capacity of a system without having to re-engineer or cause a forklift upgrade of existing equipment is extremely important to enterprises that cannot afford downtime. That is why the DPoE ™ Power System allows capacity upgrades to take place while existing infrastructure continues in full operation.

DPoE ™ Powering Options The table below shows nine powering options. The columns on the left indicate choices for powering using the DPoE ™ Power System rectifier options. The columns on the right indicate the total wattage available for the solution as well as a range of the number of Powered Devices (PDs) that can be accommodated by the powering option. The number of devices is calculated according to the IEEE recommendation for class 1 devices at 3.84 watts, class 2 at 6.49 watts, and class 3 at 12.95 watts.

Configuring for Power Step 1. Determine the power (or class) rating of the devices. A mix of power devices can be averaged with various power ratings. If power rating is unknown, utilize the highest power rating. Step 2. Determine the number of power devices to be supported. Step 3. Calculate the number of DPoE ™ Power Patch Panels to be installed by dividing the number in the previous step by 24. Note: A single DPoE ™ Power System can support up to 14 panels. Step 4. From the quantity determined in step 2, choose the powering option which best meets the needs of the configuration.
