Introduction Overview 1 Introduction This chapter provides an overview of: ■ Power over Ethernet (PoE/PoE+). ■ A list of reasons why you might want to implement PoE in your network environment. ■ How PoE supplies power over twisted pair cable. ■ The capabilities of the devices used to provide PoE.
Introduction Overview The technology is bound to make a big impact in the world of embedded computing. In the realm of embedded computers, where the systems are increasingly connected to LANs and the internet, the advantages of providing power and data through a single cable should be obvious. Consider a typical application: a system for a multi-level car parking garage that includes security cameras, information signs, call-for-help telephones and vehicle sensors.
Introduction Overview Power over Ethernet connections to embedded computers will allow a less expensive installation (no AC cabling, lower labor costs), facilitate updating the installation and repositioning of end devices (wireless access points, security cameras, and so forth) without electricians, while maintaining full control over every node through the internet. Figure 1-1 shows a typical system implemented to power telephones and wireless access points.
Introduction Power Through the Cable Here are some reasons why you might want to do this: ■ Simplifies installation and saves space - only one set of wires to bring to your appliance. ■ Saves time and money - there is no need to pay for additional electrical power runs or to delay your installation schedule to make them. ■ Minimal disruption to the workplace - the appliance can be easily moved, to wherever you can lay a LAN cable. ■ Safer - no AC voltages need to be added for additional network devices.
Introduction PoE Capabilities of the HP Products An obvious requirement of the specification is to prevent damage to existing Ethernet equipment. A discovery process, run from the PSE, examines the Ethernet cables, looking for devices that comply with the specification. It does this by applying a small current-limited voltage to the cable and checks for the presence of a 25k ohm resistor in the remote device.
Introduction PoE Capabilities of the HP Products HP ProCurve 2520 Switches The 2520 (J9137A), has 8 Integrated PoE auto-sensing 10/100Base-TX RJ-45 ports with two dual-personality Gigabit Uplink ports. The 2520 (J9138A), has 24 Integrated PoE auto-sensing 10/100Base-TX RJ-45 ports and two 10/100/1000Base-TX uplink ports, with two dual-personality Gigabit Uplink ports. These switches also support some pre-standard PoE devices. For a list of these devices, see the FAQs for your switch model.
Introduction PoE Capabilities of the HP Products These switches also support some pre-standard PoE devices. For a list of these devices, see the FAQs for your switch model. This feature is enabled by default. The dual-personality ports have either auto-sensing 10/100/1000Base-T RJ-45 or mini-GBIC connectivity. The dual-personality ports do not support PoE.

Introduction PoE Capabilities of the HP Products Power Redundancy for the 2600 and 2610 Switches The internal power supply in these switches provides both the 12V (RPS) and 50V (EPS) circuits. If either the 12V or 50V fails, the power supply shuts down which will bring down all switch and PoE connections. Therefore it is important to provide a redundant power supply for both the 12V and 50V circuits.
Introduction PoE Capabilities of the HP Products HP E2620-PoE+ Switches The HP Switch E2620-48-PoE+ (J9627A), has 48 Integrated PoE+ auto-sensing 10/100/1000Base-T RJ-45 ports with four Gigabit Uplink ports. The HP Switch E2620-24-PoE+ (J9625A), has 24 Integrated PoE+ auto-sensing 10/100/1000Base-T RJ-45 ports with two Gigabit Uplink ports. The HP Switch E2620-24-PPoE+ (J9624A), has 24 Integrated PoE+ autosensing 10/100/1000Base-T RJ-45 ports with two Gigabit Uplink ports.
Introduction PoE Capabilities of the HP Products Power Redundancy for the E2620 Switches The internal power supply in these switches provides both the 12V (RPS) and 54V (EPS) circuits. If the 54V portion of the power supply fails, it will only shut down the PoE connections. However, if the 12V portion of the power supply fails, it will shut down the entire switch. Therefore it is important to provide a redundant power supply for both the 12V and 54V circuits.
Introduction PoE Capabilities of the HP Products These switches also support some pre-standard PoE devices. While HP strives to support as many non-standard devices as possible, some devices in the market are designed in ways that are restrictive, or exclusive of the IEEE standard and thus cannot be supported. For a list of these devices, see the FAQs for your switch model at www.hp.com/networking/support, and click on faqs. This feature is the default and you must disable it if you do not want to use it.
Introduction PoE Capabilities of the HP Products HP ProCurve 2915G Switch The HP ProCurve Switch 2915-8G-PoE (J9562A), has 8 Integrated PoE autosensing 10/100/1000Base-TX RJ-45 ports with two dual-personality Gigabit Uplink ports. There is no power redundancy for this switch. These switches also support some pre-standard PoE devices. For a list of these devices, see the FAQs for your switch model. This feature is enabled by default.
Introduction PoE Capabilities of the HP Products HP ProCurve 3500-PoE Switches The HP ProCurve Switch 3500-48G-PoE (J9473A), has 44 Integrated PoE autosensing 10/100 Base-T RJ-45 ports and four ports of Gigabit dual-personality Uplink ports, either RJ-45 or SFP. The HP ProCurve Switch 3500-24G-PoE (J9471A), has 20 Integrated PoE autosensing 10/100 Base-T RJ-45 ports with four ports of Gigabit dual-personality Uplink ports, either RJ-45 or SFP. These switches also support some pre-standard PoE devices.
Introduction PoE Capabilities of the HP Products The HP ProCurve 3500-PoE Switches can be connected to a 620 RPS/EPS (J8696A) and receive full redundant power from the RPS part of the unit for switch operation if the internal power supply in the switch fails. If two switches are connected to the RPS ports and both switches lose power at the same time, they both receive redundant power. The 620 RPS/EPS unit can provide all the power necessary to keep two switches running.
Introduction PoE Capabilities of the HP Products Power Redundancy for the 3500yl PWR Switches The internal power supply in these switches provides both the 12V (RPS) and 50V (EPS) circuits. If the 50V portion of the power supply fails, it will only shut down the PoE connections. However, if the 12V portion of the power supply fails, it will shut down the entire switch. Therefore it is important to provide a redundant power supply for both the 12V and 50V circuits.
Introduction PoE Capabilities of the HP Products For more information, refer to the Management and Configuration Guide for your switch at www.hp.com/networking/support. The dual-personality ports have either auto-sensing 10/100/1000Base-T RJ-45 or mini-GBIC connectivity. The mini-GBIC ports do not support PoE. If any of the mini-GBIC ports are used the corresponding RJ-45 port will not be supplied with PoE power.
Introduction PoE Capabilities of the HP Products The HP E3800-48G-PoE+-4XG Switch (J9588A), has 48 Integrated PoE autosensing 10/100/1000Base-T RJ-45 ports with four XG ports. The E3800-24G-PoE+-2XG Switch (J9587A), has 24 auto-sensing 10/100/1000T RJ-45 ports and two XG ports. These switches also support some pre-standard PoE devices. For a list of these devices, see the FAQs for your switch model. This feature is disabled by default and must be enabled to use it.
Introduction PoE Capabilities of the HP Products HP E5400zl/E8200zl Switches The HP Switch E5406zl is a chassis that can hold up to six 24-port modules to provide up to 144 10/100/1000Base-T RJ-45 ports for PoE/PoE+ power. The HP Switch E5412zl is a chassis that can hold up to twelve 24-port modules to provide up to 288 10/100/1000Base-T RJ-45 ports for PoE/PoE+ power.
Introduction PoE Capabilities of the HP Products The HP Switch E8206zl is a chassis that can hold up to six 24-port modules to provide up to 144 10/100/1000Base-T RJ-45 ports for PoE/PoE+ power.
Introduction PoE Capabilities of the HP Products The HP Switch E8212zl is a chassis that can hold up to twelve 24-port modules to provide up to 288 10/100/1000Base-T RJ-45 ports for PoE/PoE+ power. Note The E5412zl chassis and the E8212zl chassis share a completely common PoE/PoE+ implementation. Port counts, power supply wattages, specifications, and functionality for these two platforms are the same with respect to PoE/PoE+.
Introduction PoE Capabilities of the HP Products The 12V system power is used to operate the internal components of the switch. The 50V PoE or 54V PoE/PoE+ power is used to power the PoE devices connected to the modules. It is important to provide a secondary power supply for redundancy purposes for both the 12V and 50V or 54V circuits. The internal power supply in these switches provides both the 12V (system) and 50V (PoE) or 54V (PoE+) circuits. If the 12V (system) power fails the switch will shut down.
Introduction PoE Capabilities of the HP Products PoE Chassis Power Supplies Note HP highly recommends that the two types of power supplies are not mixed in the same chassis. For PoE only, the following power supplies can be used: ■ ■ J8712A, which operates at 100-127 volts drawing a maximum of 11.5 amps, or 200-240 volts drawing a maximum of 5.
Introduction PoE Capabilities of the HP Products Configuring PoE Redundancy When considering redundant power, also consider the power source for the power supplies. Each power supply should be connected to a separate power source circuit in order to supply complete redundancy. Should one circuit fail, it would then be possible for the other circuit to continue supplying power to the second power supply in the switch, keeping the switch running.

2 Operating Rules This chapter discusses the operating rules and characteristics of the HP ProCurve product capabilities, switches and external power supplies.
Operating Rules Overview of Switch PoE Operation Overview of Switch PoE Operation ■ ■ ■ ■ ■ ■ ■ ■ ■ ■ 2-2 The Switch 2520-8-PoE provisions (allocates power to) ports 1-8 with 67 watts of power for PoE applications compatible with the IEEE 802.3af standard. The Switch 2520-24-PoE provisions ports 1-24 with 195 watts of power for PoE applications compatible with the IEEE 802.3af standard.
Operating Rules Overview of Switch PoE Operation ■ ■ ■ ■ Note The Switch 3500yl-24G-PoE+ can supply up to 398 watts of PoE power across the 24 ports. The Switch 3500yl-48G-PoE+ can supply up to 398 watts of PoE power across the 48 ports for PoE+ applications compatible with the IEEE 802.3at standard.
Operating Rules Configuring PoE/PoE+ Power Using the CLI Configuring PoE/PoE+ Power Using the CLI Allocating PoE Power by Class or User-defined Power Level The 2910al, 3500, 3500yl, E3800 and the E5400zl/E8200zl switches provide maximum flexibility by allowing the switch to detect and display 802.3af or 802.3at device class, but does not enforce the power level specified in each device class.
Operating Rules Configuring PoE/PoE+ Power Using the CLI Switch Priority Class Using a priority class method, a power priority of Low (the default), High, or Critical is assigned to each enabled PoE port. This assignment is done through the command line interface of the switch and alters the hardware port-number priority for power allocation. ■ Low (default) - This priority class receives power only if all other priority classes are receiving power.
Operating Rules PoE Power Characteristics For example if the threshold is set at 50%, the switch informs you that the switch has exceeded the threshold when 51% of available PoE power is being used. For more information, see the Management and Configuration Guide for your switch at: www.hp.
Operating Rules PoE Power Characteristics As you can see in the table for classifications 0-3, any 802.3af compliant PD will never require more than 12.95 watts. The switch provides a minimum of 15.4 watts at the port in order to guarantee enough power to run a device, after accounting for line loss. For classification 4, the switch provides 30 watts at the port in order to guarantee enough power to run a device, after accounting for line loss.
Operating Rules Provisioning Power for PoE Provisioning Power for PoE All of these PoE switches support an external power supply that can provide either redundant or extra PoE power. It is important to understand how PoE power is provisioned in order to use these external power supplies efficiently. The following chapters will discuss this in detail.
Operating Rules Provisioning Power for PoE Table 2-2. Maximum Power Allocations PoE Devices Internal Only PoE for Switches 2520-8-PoE and 2520G-8-PoE 67 watts available to ports 1-8. PoE for Switch 2520-24-PoE and 2520G-24-PoE 195 watts available to ports 1-24.
Operating Rules Provisioning Power for PoE Table 2-3. Maximum Power Allocations PoE Devices Internal Only Internal and EPS EPS Only PoE for Switch 2600-8-PWR 126 watts available to ports 1-8. 126 watts available to ports 1-8 (provided by the internal source). 408/204* watts available, provided by the EPS source. The internal power supply has failed, and the EPS provides 408/204* watts to ports 1-8. PoE for Switch 2626-PWR 406 watts available to ports 1-24.
Operating Rules Provisioning Power for PoE The Switch 2626-PWR has 24 ports and its internal PoE power supply provides 406 watts across all 24 ports. If a 600 RPS/EPS or a 610 EPS device is connected to the Switch 2626-PWR for the purpose of supplying external power to the PoE portion of the switch, there will be either 408 watts or 204 watts of power available should the switch’s internal PoE power supply fail.
Operating Rules Provisioning Power for PoE Table 2-4. Maximum Power Allocations PoE Devices Internal Only Internal and EPS EPS Only PoE for Switch 2610-24/12PWR 126 watts available to ports 1-12 126 watts available to ports 1-12 (provided by the internal source). 408/ 204* watts available, provided by the EPS source. The internal power supply has failed, and the EPS provides 408/204* watts to ports 1-12. PoE for Switch 2610-24-PWR 406 watts available to ports 1-24.
Operating Rules Provisioning Power for PoE single switch is connected to the EPS ports on the 600 RPS/EPS or a single port of a pair on the 610 EPS, 408 watts are available, providing fully redundant PoE power to the switch. If two switch devices are connected to the EPS ports on the 600 RPS/EPS or to both ports of a pair on the 610 EPS, only 204 watts are provided to the switch if the internal PoE power supply fails. The Switch 2610-48-PWR PoE power requirements are different.
Operating Rules Provisioning Power for PoE Since there is no external power supply available for this switch, PoE power is limited to 67 watts provisioned across all 8 ports. Therefore, proper provisioning is very important. HP E2620-PoE+ Switches Maximum PoE+ Power The Switch E2620-24-PPoE+ provisions (allocates power to) ports 1-12 with 126 watts of power for PoE and PoE+ applications compatible with the IEEE 802.3af and the 802.3at standard and some pre-standard devices.
Operating Rules Provisioning Power for PoE PoE/PoE+ Allocation Using LLDP Information A PoE port can automatically configure certain PoE+ link partner devices if the device supports advertising of its PoE needs. By enabling PoE LLDP detection, available information about the power requirements of the PD may be used by the switch to configure the power allocation. The initial configuration for PoE ports may change if more accurate configuration information is provided by way of LLDP.
Operating Rules Provisioning Power for PoE PoE Power Requirements The Switch 2910al-24G-PoE+ has 24 ports with an internal PoE power supply that provides 382 watts of power across all 24 ports. The Switch 2910al-48GPoE+ has 48 ports with 382 watts of power across all 48 ports. The HP ProCurve 630 RPS/EPS can provide an extra 388 watts for a total of 770 watts.
Operating Rules Provisioning Power for PoE Since there is no external power supply available for this switch, PoE power is limited to 67 watts provisioned across all 8 ports. Therefore, proper provisioning is very important. HP ProCurve 3500-PoE Switches Maximum PoE Power The HP ProCurve 3500-24-PoE switch provisions (allocates power to) ports 1-24 with 398 watts of power for PoE applications compatible with the IEEE 802.3af standard and some pre-standard devices.
Operating Rules Provisioning Power for PoE 25-48, so that neither set of ports receives the entire 398 watts. This is designed for the integrity and safety of PoE during power balancing to properly detect PDs and bring them online. PoE Allocation Using LLDP Information You can have the port automatically configure certain PoE link partner devices if the devices supports advertising of its PoE needs.

Planning and Implementation for the E5400zl/E8200zl Switches Configuration Examples Configuration Examples In the following configuration examples, each example shows a complete configuration. A table shows the PoE power available to connected PoE devices when using just the switch and when connecting an external power supply.
Planning and Implementation for the E5400zl/E8200zl Switches Configuration Examples To achieve the 16 ports at 15.4 watts the PoE devices must be divided up and connected to two different modules. Remember, as soon as a module is installed into the switch, 22 watts are reserved for its use. In order to use those watts, devices must be connected to that module or PoE power must be disabled to all ports on that module.
Planning and Implementation for the E5400zl/E8200zl Switches Configuration Examples In this example the load must be balanced or split between two or three modules in order to effectively use all 546 watts. The number of devices and wattage must be split between the modules. This would also help limit the effects of a single module failure. If one module fails, only the devices on that module would lose power.

Planning and Implementation for the E5400zl/E8200zl Switches Configuration Examples In a system with mixed power supplies, failover is calculated based on the largest power supply failing. If it turns out to be the smaller power supply that fails, some of the ports that were powered off during the power failure will come back on. For example, in figure 4-5 there are mixed power supplies offering 900 W+ 273 W for 1173 W total.

14 Infrastructure Requirements Air conditioning Power supplies create a great amount of heat. Ensure you have enough cool air to maintain an ambient temperature between 0°C to 50°C (32°F to 131°F) around the switch devices inside the rack or equipment closet. If you are installing any of the X2 transceivers the operating ambient temperature should not exceed 40°C (104°F). See transceiver specifications in the installation guide for your switch. A typical 48 port PoE switch BTU rating is approximately 920.
Infrastructure Requirements Physical Space Many switches come with dual power ratings (110 or 220 volt operation). Therefore planning for power requirements is critical. If a wiring closet currently only supplies 110 volts it must be determined whether or not to operate the switch at 110 volts or 220 volts. You not only need to plan for voltage requirements but amperage requirements. PoE switches can be double or triple the amperage draw compared to a non-PoE switch.
Glossary Glossary active PoE port - PoE-enabled port connected to a PD and currently delivering power. priority class - Refers to the type of power prioritization where the switch uses Low (the default), High, and Critical priority assignments to determine which groups of ports will receive power. Note that power priority rules apply only if PoE provisioning on the switch becomes oversubscribed.
