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

■ How PoE supplies power over twisted pair cable.

■ The capabilities of the devices used to provide PoE.

Overview

environment.

Power over Ethernet technology allows IP telephones, wireless LAN Access Points and other appliances to receive power as well as data over existing LAN cabling, without needing to modify the existing Ethernet infrastructure.

Power over Ethernet has become a standard feature of ethernet switches, as the cost of adding power supplies to the Ethernet switches is small. IEEE

802.3af is an extension to the existing Ethernet standards. It offers the first truly international standard for power distribution (consider how many different AC power plugs exist worldwide).

Almost all appliances require both data connectivity and a power supply. Just as telephones are powered from the telephone exchange through the same twisted pair that carries the voice, we can now do the same thing with Ethernet devices.

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. Such a system is distributed over a significant area, where main power is not easily available. A single link to a PoE Ethernet Switch makes implementing this system less expensive and faster than using a non-PoE switch.

Introduction

Overview

Since the original introduction of PoE, the IEEE has initiated a new project called 802.3at which is commonly referred to as PoE+. This project enhances PoE in a couple of very important ways. First, it provides up to 30W of power to a Powered Device (PD), 25.5 watts to the device and 4.5 for line loss, and allows this power to also run on cabling designed for 1000BASE-T. Secondly, it provides a new mechanism for communicating power capability and requirements using the 802.1ab Link Layer Discovery Protocol (LLDP). This protocol addition allows PoE+ switches to deliver power more efficiently and thereby provide power to more devices for a given power supply capacity. The new standard is going to be a superset of the 802.3af because it provides all the same functionality, and more. The table below shows the capabilities of

802.3af versus 802.3at.

Classification Discovery

Power to PD Physical Logical

<25.5W 802.3at 802.3at

<12.95W 802.3af

802.3at

In order for 802.3at to provide higher power, Class D (Cat5e) or better cables are required. 802.3at also increases the minimum output voltage of the Power Source Equipment (PSE) from 44 volts to 50 volts. For this reason, you may note that ProCurve PoE+ devices use a 54 volt power supply.

802.3at

Note The detection and classification functions ensure that if two PoE sources are

attached together, power will not be improperly applied.

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. The PoE Ethernet switches are installed to supply power over the twisted pair LAN cables to run phones or other appliances as required.

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.

■ As well as the data transfer to and from the appliance, you can use SNMP

network management infrastructure to monitor and control the appliances.

■ Appliances can be shut down or reset remotely - no need for a reset button

or power switch.

■ When implementing wireless LAN systems it simplifies the radio

frequency (RF) survey task, as the access point can easily be moved and wired in.

Power Through the Cable

A standard CAT5 Ethernet cable has four twisted pairs. Only two of these pairs are used for 10Base-T and 100Base-TX data; all four are used for 1000Base-T data. The specification allows two options for using these cables for power:

■ The spare pairs are used. The pair on pins 4 and 5 are connected

together and form the positive supply, and the pair on pins 7 and 8 are connected and form the negative supply.

■ The data pairs are used. Since Ethernet pairs are transformer coupled

at each end, it is possible to apply DC power to the center tap of the isolation transformer without upsetting the data transfer. In this mode of operation the pair on pins 1 and 2 and the pair on pins 3 and 6 can be of either polarity.

The 802.3af standard does not allow both pairs (spare and data) to be used a choice must be made. The Power Sourcing Equipment (PSE) applies power to either set of wires. HP ProCurve Networking switches, as a PSE, supply PoE power over the “data pair” or, pins 1 and 2, and the pair on pins 3 and 6. The Powered Device (PD) must be able to accept power from both options because mid-span equipment must (according to the specification) supply power over the “spare pair” or pins 4 and 5, and the pair on pins 7 and 8.

PoE Capabilities of the Products

Introduction

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. Only if the resistor is present, will the full wattage be applied, but this is still current-limited to prevent damage to cables and equipment in fault conditions.

Once discovered, a different voltage is applied, and based upon the current drawn, the class of device can be determined. This indicates how much power is to be drawn. The 802.3at standard provides both a physical classification and a logical classification, which is even more precise.

The PD must continue to draw a minimum current. If it does not (for example, when the device is unplugged) then the PSE removes the power and the discovery process begins again.

Introduction

PoE Capabilities of the Products

These switches are designed to be used primarily in wiring closets directly connected to computers, printers, and servers to provide dedicated bandwidth to those devices. Additionally, they support the PoE standard IEEE

802.3af, and the PoE+ IEEE 802.3at standard. They can supply power over a twisted-pair cable to power devices such as telephones, wireless access points, IP Gateways, and audio and video remote monitoring.

The HP ProCurve PoE switch devices are multi-port switches that can be used to build high-performance switched workgroup networks with PoE. These switches are store-and-forward devices that offer low latency for high-speed networking. The PoE switches are designed to support Redundant Power Supply and Power over Ethernet (PoE and/or PoE+) technologies.

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. Thus when you connect EPS from a 600 RPS/EPS device to one of the 2600-PWR Switches or one of the 2610-PWR Switches, you should also connect the RPS as well to provide full redundant power.

The 2600-PWR Switches and 2610-PWR Switches can be connected to a 600 RPS/EPS 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 multiple switches are connected to the RPS ports and several switches lose power at the same time, the switch attached to the lowest RPS port number receives power. The 600 RPS/EPS unit can provide all the power necessary to keep one switch running.

EPS power from the 600 RPS/EPS is the PoE capability of the device. It supplies backup and additional PoE power for the ports of the 2600-PWR and 2610-PWR switches.

The 610 EPS can also be used for this purpose, to supply PoE power only. The 610 EPS cannot supply RPS power, it can only supply PoE power. Refer to chapter three, four, and five for more information on capabilities and connectivity of these switches, components and accessories.

HP ProCurve 2910al Switches

The HP ProCurve Switch 2910al-48G-PoE+ (J9148A), has 44 Integrated PoE+ auto-sensing 10/100/1000Base-T RJ-45 ports with four dual-personality Gigabit Uplink ports.

The HP ProCurve Switch 2910al-24G-PoE+ (J9146A), has 20 Integrated PoE+ auto-sensing 10/100/1000Base-T RJ-45 ports with four dual-personality Gigabit Uplink ports.

These switches also support some pre-standard PoE devices. While HP ProCurve 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, www.hp.com/go/procurve/faqs. This feature is the default and you must disable it if you do not want to use it. For example:

ProCurve 2910al#(config) no power pre-std-detect

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/PoE+ power.

Introduction

PoE Capabilities of the Products

Power Redundancy for the 2910al 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. It is recommended that both EPS and RPS be connected to provide full redundancy.

HP ProCurve Redundant/External Power Supplies (RPS/EPS) can be connected to the 2910al Switches for redundant 12 V system power (RPS) and to provide for additional PoE+ provisioning. For RPS power, the 2910al Switches can be connected to either an HP ProCurve 620 RPS/EPS or HP ProCurve 630 RPS/EPS. For additional PoE+ EPS power, only the 630 can be used. The 620 does not provide 54 V for PoE+, only 50 V for PoE, and the 2910al Switches do not support connections to the 620 for EPS.

The 2910al switch provides up to 30W from each port (25.5W for PD, 4.5W for cable dissipation); the number of ports that can be operated at full power is limited to 12 ports at full power, and/or 24 ports at 15.4W. To increase the capacity of the switch, an external power supply can be attached to double the total system capacity to 24 ports at 30W, or 48 ports at 15.4W.

The power supplies for these switches are optimized to provide the most efficient and cost effective solution.

The 620 RPS/EPS unit can provide all the power necessary to keep two switches running.

If maximum PoE power is to be used on all 48 ports, you must connect an HP ProCurve 620 RPS/EPS, since the internal power supply only has enough power to supply 24 ports with maximum wattage. In this case, there is no redundancy.

The HP ProCurve 630 RPS/EPS unit can provide all the power necessary to keep only one switch running.

The "maximum PoE+" power for 48 ports equals (48 ports x 30 watts = 1440 watts). The 398 watts of internal power plus the 382 watts from the EPS equals 780 watts. This will only support "maximum PoE+" power on 24 of the 48 ports. The internal power supply can only support "maximum PoE+" on 12 of 48 ports (or 12 of 24 ports on 24 port PoE+ switch).

The HP ProCurve Switch 8212zl 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 5412zl chassis and the 8212zl 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+.

Power Redundancy for the5400zl/8200zl Switches

There are three types of power supplied by the Series 5400zl/8200zl switch power supplies:

■ 12V power or system power

■ 50V power for PoE power

■ 54V power for PoE/PoE+ power

1-19

Introduction

PoE Capabilities of the 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. If the 50V or 54V fails, all PDs would lose power. Therefore, to keep the switch running should one power supply, or either power source fail, you should install a second power supply.

The 5406zl/8206zl chassis can hold two internal power supplies and the 5412zl/8212zl chassis can hold four internal power supplies.

PoE/PoE+ Power Supplies

Why Mixing Power Supplies is NOT Supported

Using a combination of zl PoE power supplies J8712A and J8713A and a J9306A zl power supply in PoE/PoE+ systems is NOT supported. Use the J9306A zl power supply for systems providing PoE and PoE+ power.

The reason the power supplies should not be mixed is because the J8712A and J8713A power supplies provide PoE power at 50 volts (273 watts for J8712A and 900 watts for J8713A). The J9306A zl power supply provides PoE/PoE+ power at 54 volts (300 watts at 110 volts and 900 watts at 220 volts). If you install a J8712A or J8713A with a J9306A power supply, they do voltage sharing. This means that the 54 volts of the J9306A zl power supply will supersede the 50 volts of the J8712A or J8713A power supplies. Only the J9306A will provide PoE/PoE+ power.

For example, if an HP ProCurve 5406zl switch on a 110 volt circuit has a J8712A installed, and then a J9306A is inserted, the switch only provides 300 watts of power, not 573 watts (273 watts + 300 watts). Only the J9306A provides PoE/ PoE+ power, which is 300 watts.

In another example, if an HP ProCurve 8212zl switch on a 220 volt circuit has three J8713A power supplies installed, and then a J9306A is inserted, the switch only provides 900 watts of PoE/PoE+ power, not 3600 watts (2700 watts from the three J8713A power supplies and 900 watts from the J9306A power supply). Only the J9306A will provide PoE/PoE+ power.

Introduction

PoE Power Supplies

Note HP ProCurve Networking 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 5.7 amps, and supplies 273 watts of PoE power

■ J8713A, which operates at 200-220 volts drawing a maximum of 10 amps,

and supplies 900 watts of PoE power

Using two J8712As, or two J8713As, or a mix of both is supported (however mixing power supplies is not recommended, see page 10-7 for more information) and necessary to ensure the switch has both 12V (system power) and 50V (PoE power) should one power supply fail. See the HP ProCurve Switch zl Internal Power Supplies Installation Guide, for more information and specifications on these power supplies.

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.

There is also an external power supply, the HP ProCurve Switch zl Power Supply Shelf (J8714A), that can be connected to either the 5400zl switches or the 8200zl switch for the purpose of adding extra or backup 50V (PoE power). The zl Power Supply Shelf will not supply any 12V (system power) to any zl switch, since the switch is provided with 12V redundancy when more than one power supply is installed in the chassis.

PoE/PoE+ Power Supply

For PoE or PoE+, the J9306A power supply can be used. This power supply operates at 110-127V providing 300 watts of PoE/PoE+ power, or 200-240V providing 900 watts of PoE/PoE+ power. See the HP ProCurve Switch zl Internal Power Supplies Installation Guide for more information and specifications on this power supply.

There is also an external power supply, the HP ProCurve Switch zl Power Supply Shelf (J8714A), that can be connected to either the 5400zl switches or the 8200zl switches to add extra or backup 54V (PoE/PoE+) power. The zl Power Supply Shelf will not supply any 12V (system power) to any zl switch, since the switch is provided with 12V redundancy when more than one power supply is installed in the chassis.

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.

When PoE redundancy is enabled, PoE redundancy occurs automatically. The switch keeps track of power use and won’t supply PoE power to additional PoE devices trying to connect if that results in the switch not having enough power in reserve for redundancy if one of the power supplies should fail. There are three configurable redundancy methods:

■ No PoE redundancy enforcement (default). All available power can be

■ Full redundancy: half of the totally available PoE power can be allocated

■ N+1. One of the power supplies is held in reserve for redundancy. If a

allocated.

and half is held in reserve for redundancy. If power supplies with different ratings are used, the highest-rated power supply is held in reserve to ensure full redundancy.

single power supply fails, no powered devices are shut down. If power supplies with different ratings are used, the highest-rated power supply is held in reserve to ensure full redundancy.

Note When changing from one method to another, always check the current level

of PoE usage before implementing the change. The change could cause existing connection to lose PoE power.

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.

at 110-127V and 900 watts of PoE/PoE+ power at 200-240V. Mixing this power supply with any other type of power supply is NOT supported.

Note HP ProCurve Networking highly recommends that power supplies are not

mixed in the same 5400zl/8200zl chassis or Power Supply Shelf.

Operating Rules

Configuring PoE/PoE+ Power Using the CLI

Allocating PoE Power by Class or User-defined Power Level

The 2910al, 3500, 3500yl and the 5400zl/8200zl 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. In addition to this, the switch can allocate PoE/PoE+ power according to the power level specified in each device class or a level defined by the customer.

There are three methods to allocate PoE power:

■ By device usage (default). The switch does not enforce the power limit.

■ By power level specified in 802.3af or 802.3at. The device class will be

detected according to the specification and power limits will be enforced.

■ By user-defined. Configurable per port values or a range of ports to power

level 1-17 watts or 1-33 watts for the 2910al and 3500yl-PoE+ Switches. Incorrectly setting the PoE maximum value to be less than the device requires will result in a PoE fault.

Switch Port Priority

Using a port-number priority method, a lower-numbered port has priority over a higher-numbered port within the same configured priority class, for example, port A1 has priority over port A5 if both are configured with High priority.

A port can be assigned a power priority that alters the assignment of power to it by the switch. For more information, see the Management and Configuration Guide on the ProCurve Web site at:

www.hp.com/go/procurve/manuals

Configuring PoE/PoE+ Power Using the CLI

Operating Rules

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. If there is enough power to provision PDs on only some of the ports with a low priority, then power is allocated to the ports in ascending order, beginning with the lowest-numbered port in the class until all available power is in use.

■ High - This priority class receives power only if all PDs on ports assigned

with a critical priority are receiving full power. If there is not enough power to provision PDs on ports assigned with a high priority, then no power goes to the low priority ports. If there is enough power to provision PDs on only some of the high priority ports, then power is allocated to the high priority ports in ascending order, beginning with lowest-numbered high priority port, until all available power is in use.

■ Critical - This priority class is the first to be allocated power. If there is

not enough power to provision PDs on all of the ports configured for this class, then no power goes to “High or Low” priority ports. If there is enough power to provision PDs on only some of the critical ports, then power is allocated to the critical ports in ascending order, beginning with the lowest-numbered port in the class.

Operating Rules

Configuring PoE/PoE+ Power Using the CLI

Threshold

You can configure one of the following thresholds:

■ A global power threshold that applies to all modules on the switch.

This setting acts as a trigger for sending a notice when the PoE power consumption on any PoE module installed in the switch crosses the configured global threshold level. (Crossing the threshold level in either direction—PoE power usage either increasing or decreasing— triggers the notice.) The default setting is 80%.

■ A per-slot power threshold that applies to an individual PoE module

installed in the designated slot. This setting acts as a trigger for sending a notice when the module in the specified slot exceeds or goes below a specific level of PoE power consumption.

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.

PoE Power Characteristics

Operating Rules

PoE Power Characteristics

Line Loss

A certain amount of power is consumed by the resistance of the wire in the LAN cable connected from the switch to the powered device (typically less than 16% loss), which can be influenced by cable length, quality, and other factors. The IEEE 802.3af specification has addressed loss of power by providing more power than a powered device requires. As well, depending upon the classification (Class 0-4) of the device, the switch will provide more or less power to address the specific power needs of that end device.

PD Power Classification

A PD is classified based on the maximum power it draws across all input voltages and operational modes. The most common class is 0, in which the switch will allow a maximum draw of 15.4 watts per port. As an example, 15.4 watts - Power Loss (16%) = 12.95 watts. See table 2-7.

Table 2-1. Power Usage

Class Usage Minimum Power Levels

at Output of PSE

0 Default 15.4 watts 0.44 to 12.95 watts

1 Optional 4.0 watts 0.44 to 3.84 watts

2 Optional 7.0 watts 3.84 to 6.49 watts

3 Optional 15.4 watts 6.49 to 12.95 watts

4 Optional 30 watts 0.05 to 24.00 watts

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.

Range of Maximum Power required by the PD

2-7

Operating Rules

PoE Power Characteristics

PD Power Requirements

When a PD is initially connected to a PoE port, a minimum of 17 watts of available power is required to begin the power-up sequence. This 17 watts is needed to determine the type of PD requesting power (see “PD Power Classification” on page 2-7). Once the power classification is determined and power is supplied, any power beyond the maximum power requirements for that class of PD is available for use.

In the default switch configuration all PoE ports have a Low priority. If the switch has less than 17 W of PoE power available, the switch transfers power from lower-priority ports to higher-priority ports.

See “Switch Priority Class” on page 2-5 for information on the use of PoE port priority classifications. Within each priority class, a lower numbered port is supplied power before a higher numbered port.

Disconnecting a PD from a port causes the switch to stop providing power to that port and makes that power available to other ports configured for PoE operation.

Provisioning Power for PoE

Operating Rules

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.

By connecting an external power supply you can optionally provision more PoE wattage per port and or supply the switch with redundant 12V power to operate should an internal power supply fail.

By installing a second power supply in the 5406zl/8206zl or a third power supply in a 5412zl/8212zl chassis, depending on how many PoE ports are being supplied with power, the switch can have redundant power if one power supply fails. A Power Supply Shelf (external power supply) can also be connected to the 5400zl/8200zl switches to provide extra or redundant PoE power.

For example, if the 5406zl has two 24-port PoE modules (J8702A) installed, and all ports are using 15.4 watts, then the total wattage used is 739.2 watts (48 x 15.4). To supply the necessary PoE wattage a J8713A power supply is installed in one of the power supply slots.

To gain redundant power, a second J8713A must be installed in the second power supply slot. If the first power supply fails, then the second power supply can supply all necessary power.

PoE Power Requirements

It is important to understand the PoE power requirements of these switches because if the PoE power is not planned and implemented correctly, end devices connected to the PoE switch ports may not receive power if a switch PoE power source failure occurs or if the switch is over provisioned.

Since there is no external power supply available for these switches it is very important to understand that the 67 watts for the 8-port switches and the 195 watts for the 24-port switches are all there is for PoE power. Therefore, proper provisioning is very important.

PoE Power Requirements

It is important to understand the PoE power requirements of these switches because if the PoE power is not planned and implemented correctly, end devices connected to the PoE switch ports may not receive power if a switch PoE power source failure occurs or if the switch is over provisioned.

The Switch 2600-8-PWR has 8 ports and its internal PoE power supply provides 126 watts across all 8 ports. If a 600 RPS/EPS or a 610 EPS device is connected to the Switch 2600-8-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. If a 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. This will still provide enough wattage to be a full PoE backup for the Switch 2600-8-PWR because it only needs 126 watts.

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. If a 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 2650-PWR PoE power requirements are different. This switch has 48 ports and the internal PoE power supply supplies 406 watts across all 48 ports. The switch reserves 38 watts for either ports 1-24 or 25-48, so that neither set of ports receives the entire 406 watts.

By connecting a 600 RPS/EPS or a 610 EPS to the Switch 2650-PWR, more PoE power is provided to the switch. With the 600 RPS/EPS or the 610 EPS connected to the Switch 2650-PWR, the internal PoE power supply provides the first 24 ports (1-24) with 406 watts and the 600 RPS/EPS or the 610 EPS supplies the second 24 ports (25-48) with 408 or 204 watts (408 watts if only one switch is connected to the EPS ports; 204 watts if two switches are connected to the EPS ports). If the internal PoE power supply in the 2650PWR switch fails, 408 watts or 204 watts are provided to ports 1-48. 38 watts of power are always allocated to ports 1-25 or 25-48.

The Switch 3500yl48G-PWR has 48 ports with 398 watts of 50V power across all 48 ports. There is a special power provision on the Switch 3500yl-48G-PWR, Where the switch reserves 22 watts for each bank of 24 ports, ports 1-24 and 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/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. By enabling PoE LLDP detection, available information about the power usage of the PD will be used by the switch to configure the power allocation. The default configuration is for PoE information to be ignored if detected through LLDP.

For more information, see the Management and Configuration Guide on the ProCurve Web site at www.hp.com/go/procurve/manuals.

HP ProCurve 3500yl PoE+ Switches

Maximum PoE Power

The Switch 3500yl-24G-PoE+ provisions (allocates power to) ports 1-24 with 398 watts of power for PoE and PoE+ applications compatible with the IEEE

802.3af and the 802.3at standard and some pre-standard devices. The Switch 3500yl-48G-PoE+ provisions ports 1-48 with 398 watts. This reduces the average per port wattage by half as compared to the Switch 3500yl-24G-PoE+.

An external power supply, the HP ProCurve 630 Redundant and/or External (HP ProCurve 630 RPS/EPS) power supply (J9443A either of the 3500yl PoE+ switches to provide redundant or extra PoE+ power. The HP ProCurve 630 RPS/EPS provides up to 382 watts of PoE+ power at 54 volts.

PoE Power Requirements

PoE Only Modules.

There are two PoE modules for the 5400zl/8200zl chassis and they have the same requirement for reserving 22 watts (see above). There are 22 watts per module that is always held in reserve.

■ HP ProCurve Switch zl 24-Port 10/100/1000 PoE Module (J8702A)

■ HP ProCurve Switch zl 20-Port 10/100/1000 + 4-port Mini-GBIC Module

(J8705A)

Each group of 24 ports is its own management group and needs to have a minimum allocation associated with it in order to properly detect PDs and bring them online.

Each group of 24 ports will have a PoE power allocation of at least 22 watts. This 22 watts must be subtracted from the total wattage when figuring how many PoE devices to connect to which ports on a switch or module. In order to be able to allocate the reserved 22 watts, either use the ports it is allocated to, or the PoE power to all ports on the associated module must be turned off.

PoE/PoE+ Modules.

There are three zl modules that can provide PoE/PoE+ power to the 5400zl/ 8200zl switches. A minimum of 17 watts is required to power up a port used for PoE; a minimum of 33 watts is required to power up a port used for PoE+. There is a maximum limit of 370 watts of PoE/PoE+ power available per slot.

Planning and Implementation for the 2520 and 2520G Switches

This chapter discusses the planning process a user should follow to successfully implement PoE using a 2520 or 2520G Switch. After understanding what PoE is and its operating rules, the next step to implementation is planning. See “General Considerations” page A-1, for an example list of considerations during the planning phase.

Planning the PoE Configuration

This section assists you in building a PoE configuration. Using the following examples you can plan, build, and connect PoE devices quickly and easily.

There are four configurations:

■ HP ProCurve 2520-8-PoE Switch with Gigabit Uplink

■ HP ProCurve 2520-24-PoE Switch with Gigabit Uplink

■ HP ProCurve 2520G-8-PoE Switch

■ HP ProCurve 2520G-24-PoE Switch

3

Each example shows a complete configuration. A table shows the PoE power available to connected PoE devices.

Once you have selected your specific configuration and the PoE power provided, you then add up the maximum amount of power each of your IEEE

802.3af-compliant devices require (use maximum power in watts, usually found on a product’s data sheet). Adjust this total maximum power figure by adding 16% to account for possible line loss. This value must be less than the maximum power available shown in the table for your configuration.

The following examples only show the EPS connections, however, remember these switches use a single internal power supply which provides two isolated output voltages for switch and PoE functionality. One supply voltage provides power for the switch functionality while the isolated voltage provides power for the PoE functionality. If either voltage fails, the entire power supply shuts down disconnecting all switch and PoE connections.

After understanding what PoE is and its operating rules, the next step to implementation is planning. See “General Considerations” page A-1, for an example list of considerations during the planning phase.

There are three configurations:

■ ProCurve 2600-8-PWR Switch with Gigabit Uplink

■ ProCurve 2626-PWR Switch

■ ProCurve 2650-PWR Switch

Each example shows a complete configuration including an optional 600 RPS/ EPS or 610 EPS unit. A table shows the PoE power available to connected PoE devices when using just the switch or when using the switch and either the 600 RPS/EPS or 610 EPS unit. The tables show the available power when the 600 RPS/EPS or 610 EPS unit is providing PoE power to connected switch devices.

Once you have selected your specific configuration and the PoE power provided, you then add up the maximum amount of power each of your IEEE

802.3af-compliant devices require (use maximum power in watts, usually found on a product’s data sheet). Adjust this total maximum power figure by adding 16% to account for possible line loss. This value must be less than the maximum power available shown in the table for your configuration.

If you are planning to include redundant power in your configuration you need to determine which PoE devices must receive redundant PoE power, then total their power requirements as explained in the paragraph above.

The maximum power figure must be less than the maximum power available when the switch is powered by the 600 RPS/EPS or the 610 EPS unit, taking into consideration the number of switches the 600 RPS/EPS or 610 EPS unit is powering.

Note Full redundancy is achieved by connecting both the RPS and EPS ports of the

2600-PWR Switches to the corresponding ports of a 600 RPS/EPS.

The following examples only show the EPS connections, however, remember these switches use a single internal power supply which provides two isolated output voltages for switch and PoE functionality. One supply voltage provides power for the switch functionality while the isolated voltage provides power for the PoE functionality. If either voltage fails, the entire power supply shuts down disconnecting all switch and PoE connections. Therefore it is important to provide redundancy for each isolated voltage.

ProCurve 2650-PWR Configurations

The tables in the example configurations contain entries that show the PoE power available when the 2650-PWR is used alone. When used with the 600 RPS/EPS or 610 EPS unit, additional PoE power is available to the PoE ports and PoE power is available should the switch’s internal PoE power supply fail. Table entries show the PoE power available when the 600 RPS/EPS or the 610 EPS alone provides PoE power.

In the following examples using the ProCurve 2650-PWR switch, reference is made to two blocks of ports: ports 1-24 and ports 25-48. This applies when external PoE power is available from an 600 RPS/EPS or 610 EPS unit. In that case, the internal switch PoE power supply provides 406 watts of power to ports 1-24 and the 600 RPS/EPS or 610 EPS provides 408 watts of power to ports 25-48.

If you are using the ProCurve 2650-PWR Switch with external PoE power, the number of ports with available PoE power when the switch is powered by just the 600 RPS/EPS or 610 EPS unit may be less than the number of ports powered when both the switch and the 600 RPS/EPS or 610 EPS unit are supplying power. In the default configuration the number and location of ports with redundant PoE power is determined by three factors:

■ The number of switches drawing external PoE power from the 600 RPS/

EPS or 610 EPS unit. If only a single switch is using external PoE power the 600 RPS/EPS or 610 EPS provides 408 watts of PoE power. If two switches are using external PoE power from the 600 RPS/EPS or two switches are connected to the same pair on the 610 EPS, a switch receives 204 watts of PoE power. Should the switch’s internal PoE power supply fail, the 600 RPS/EPS or 610 EPS provides power up to the wattage stated above.

■ When the internal PoE power supply fails, the 600 RPS/EPS reserves a

minimum of 38 watts for the less-loaded bank of ports. In the default configuration, at a minimum, the first two ports in the bank (1 and 2 or 25 and 26) will have PoE power.

Note It is the ports configured with the highest priority of either bank (1-24 or 25-

48) that will receive PoE power. For example, if the highest priority ports have been re-configured to be 23, 24 and 47, 48, then they will have PoE power.

■ In the default configuration PoE power priority is determined by port

number, with the lowest numbered port having the highest priority.

If redundant PoE power is required, use the example tables to determine how much power is available to which ports.

Planning and Implementation for the 2610-PWR Switches

This chapter discusses the planning process a user should follow to successfully implement a PoE 2610-PWR Switches. The 2610-PWR switches and the 2600-PWR switches utilize a common PoE implementation. Port counts, power supply wattages, specifications, and functionality for these two platforms are the same with respect to PoE.

After understanding what PoE is and its operating rules, the next step to implementation is planning. See “General Considerations” page A-1, for an example list of considerations during the planning phase.

Planning Your PoE Configuration

5

This section assists you in building a reliable and, if required, redundant PoE configuration. Using the following examples you can plan, build, and connect your PoE devices quickly and easily.

Your configuration may vary however this section discusses some of the more common configurations.

There are three configurations:

■ ProCurve 2610-24/12PWR Switch

■ ProCurve 2610-24-PWR Switch

■ ProCurve 2610-48-PWR Switch

Each example shows a complete configuration including an optional 600 RPS/ EPS or 610 EPS unit. A table shows the PoE power available to connected PoE devices when using just the switch or when using the switch and either the 600 RPS/EPS or 610 EPS unit. The tables show the available power when the 600 RPS/EPS or 610 EPS unit is providing PoE power to connected switch devices.

Planning Your PoE Configuration

Once you have selected your specific configuration and the PoE power provided, you then add up the maximum amount of power each of your IEEE

802.3af-compliant devices require (use maximum power in watts, usually found on a product’s data sheet). Adjust this total maximum power figure by adding 16% to account for possible line loss. This value must be less than the maximum power available shown in the table for your configuration.

If you are planning to include redundant power in your configuration you need to determine which PoE devices must receive redundant PoE power, then total their power requirements as explained in the paragraph above. The maximum power figure must be less than the maximum power available when the switch is powered by the 600 RPS/EPS or the 610 EPS unit, taking into consideration the number of switches the 600 RPS/EPS or 610 EPS unit is powering.

Note Full redundancy is achieved by connecting both the RPS and EPS ports of the

2610-PWR switches to the corresponding ports of a 600 RPS/EPS.

The following examples only show the EPS connections, however, remember these switches use a single internal power supply which provides two isolated output voltages for switch and PoE functionality. One supply voltage provides power for the switch functionality while the isolated voltage provides power for the PoE functionality. If either voltage fails, the entire power supply shuts down disconnecting all switch and PoE connections. Therefore it is important to provide redundancy for each isolated voltage.

ProCurve 2610-24/12PWR Configurations

The tables in the example configurations contain entries that show the PoE power available when the 2610-24/12PWR is used alone. When used with the 600 RPS/EPS or 610 EPS unit, PoE power is available to the PoE ports should the internal PoE power supply fail. Table entries show the PoE power available when the 600 RPS/EPS or 610 EPS alone provides PoE power.

redundant PoE power for the 12 PoE ports at 7.5 W per port or 12 ports at 15.4 W per port. Only 12 ports can be PoE powered.

■ The internal power supply can provide up to 126 W of power to be used on all

12 PoE ports. The power can be allocated up to the maximum of 12 ports, or 126 W, whichever is depleted first with a reserve of 22 W maintained by the switch for power management. If more power is needed to allow the maximum of 15.4 W on all 12 ports, an external power supply accessory is needed.

■ Also (not shown), two 2610-24/12PWR switches with a dedicated 600 RPS/

EPS unit has full redundant PoE power for both switches. The 600 RPS/EPS supplies 408 watts to one switch and 204 watts to each switch when two switches are connected to the 600 RPS/EPS.

ProCurve 2610-48-PWR Configurations

The tables in the example configurations contain entries that show the PoE power available when the 2610-48-PWR is used alone. When used with the 600 RPS/EPS or 610 EPS unit, additional PoE power is available to the PoE ports and PoE power is available should the switch’s internal PoE power supply fail. Table entries show the PoE power available when the 600 RPS/EPS or the 610 EPS alone provides PoE power.

In the following examples using the ProCurve 2610-48-PWR Switch, reference is made to two blocks of ports: ports 1-24 and ports 25-48. This applies when external PoE power is available from an 600 RPS/EPS or 610 EPS unit. In that case, the internal switch PoE power supply provides 406 watts of power to ports 1-24 and the 600 RPS/EPS or 610 EPS provides 408 watts of power to ports 25-48.

If you are using the ProCurve 2610-48-PWR Switch with external PoE power, the number of ports with available PoE power when the switch is powered by just the 600 RPS/EPS or 610 EPS unit may be less than the number of ports powered when both the switch and the 600 RPS/EPS or 610 EPS unit are supplying power. In the default configuration the number and location of ports with redundant PoE power is determined by three factors:

■ The number of switches drawing external PoE power from the 600 RPS/

EPS or 610 EPS unit. If only a single switch is using external PoE power the 600 RPS/EPS or 610 EPS provides 408 watts of PoE power. If two switches are using external PoE power from the 600 RPS/EPS or two switches are connected to the same pair on the 610 EPS, a switch receives 204 watts of PoE power. Should the switch’s internal PoE power supply fail, the 600 RPS/EPS or 610 EPS provides power up to the wattage stated above.

■ When the internal PoE power supply fails, the 600 RPS/EPS reserves a

minimum of 22 watts for the less-loaded bank of ports. In the default configuration, at a minimum, the first two ports in the bank (1 and 2 or 25 and 26) will have PoE power.

Note It is the ports configured with the highest priority of either bank (1-24 or 25-

48) that will receive PoE power. For example, if the highest priority ports have been re-configured to be 23, 24 and 47, 48, then they will have PoE power.

■ In the default configuration PoE power priority is determined by port

number, with the lowest numbered port having the highest priority.

If redundant PoE power is required, use the example tables to determine how much power is available to which ports.

After understanding what PoE is and its operating rules, the next step to implementation is planning. See “General Considerations” page A-1, for an example list of considerations during the planning phase.

Your configuration may vary however this section discusses some of the more common configurations.

There are five configurations:

■ One module with a 600 RPS/EPS

■ Two modules with a 600 RPS/EPS

■ Two modules with a 610 EPS using a separate pair of power ports

■ Two modules with a 610 EPS using the same pair of power ports

■ Four modules with a 610 EPS

Each example shows a complete configuration using either a 600 RPS/EPS or 610 EPS unit. A table shows the PoE power available to connected PoE devices

Once you have selected your specific configuration and the PoE power provided, you then add up the maximum amount of power each of your IEEE

ProCurve Switch PoE xl Module Configurations with a 600 RPS/EPS

For the ProCurve Switch xl PoE Module to function it must be installed in an ProCurve Switch 5300xl. The module will receive it’s operational power from the switch and it’s PoE power from the 600 RPS/EPS or an 610 EPS.

Figure 6-1. Example of an 600 RPS/EPS Powering One Module

In this example there is only one module connected to the 600 RPS/EPS, therefore it will be supplied with 408 watts of PoE power to be distributed to all it’s 24 ports at 15.4 watts per port.

Note When planning the installation of the ProCurve Switch xl PoE Module you

must pay attention to the cabling. In a rack type installation, the 600 RPS/EPS is installed with the EPS ports in the rear, opposite this graphic. This means the EPS cable must come from the back of the 600 RPS/EPS unit and connect to the front of the module.

Planning and Implementation for the 2910al PoE+ Switches

This chapter discusses the planning process a user should follow to successfully implement PoE+ using a Series 2910al Switch. After understanding what PoE+ is and its operating rules, the next step to implementation is planning. See “General Considerations” page A-1, for an example list of considerations during the planning phase.

Planning Your PoE Configuration

This section assists you in building a PoE+ configuration. Using the following examples you can plan, build, and connect PoE+ devices quickly and easily.

7

There are four configurations:

■ HP ProCurve 2910al-24G-PoE+ Switch

■ HP ProCurve 2910al-24G-PoE+ Switch connecting an external power

supply

■ HP ProCurve 2910al-48G-PoE+ Switch

■ HP ProCurve 2910al-48G-PoE+ Switch connecting an external power

supply

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.

Once you have selected your specific configuration and the PoE+ power provided, you then add up the maximum amount of power each device requires (use maximum power in watts, usually found on a product’s data sheet). Adjust this total maximum power figure by adding 16% to account for possible line loss. This value must be less than the maximum power available shown in the table for your configuration.

The table in this example configuration contains entries that show the PoE+ power available for the 2910al-24G-PoE+.

Figure 7-1. Example of a 2910al-24G-PoE+ Switch

If any of the mini-GBIC ports are used (21-24) the corresponding RJ-45 port will not be supplied with PoE+ power. Therefore that needs to be taken into consideration when planning per port PoE+ wattage.

If for example, port 24 is used for a mini-GBIC, then the RJ45-port 24 is disabled. Therefore the PoE+ power that was being supplied to the RJ45-port 24 is returned to the total available pool of PoE+ power.

Figure 7-2. Example of a 2910al-24G-PoE+ Switch connecting to a 630 RPS/EPS

The same considerations apply for the mini-GBIC ports as in the previous example.

One 2910al-24G-PoE switch can be supported by one 630 RPS/EPS. This is a full redundant configuration. The switch can be supplied with power should either of their internal power supplies fail. The 630 RPS/EPS can supply system power to keep the switch powered on and PoE+ power to supply the attached PoE+ devices with power.

Planning Your PoE Configuration

ProCurve 2910al-48G-PoE+ Configuration

PoE+ power requirements are figured differently for the 2910al-48G-PoE+ switch, see PoE+ Power on page 2-15. The table in this example configuration contains entries that show the PoE+ power available for the 2910al-48G-PoE+ switch.

In the default configuration PoE+ power priority is determined by port number, with the lowest numbered port (port 1) having the highest priority, and the highest numbered port (port 48) having the lowest priority.

Note It is the ports configured with the highest priority of either bank (1-24 or

25-48) that will receive PoE+ power first. For example, if the highest priority ports have been re-configured to be 23, 24 and 47, 48, then they will receive PoE+ power before the lower priority ports.

7-4

Figure 7-3. Example of a 2910al-48G-PoE+ Switch

Internal PoE+ Power Supply

For example, the switch starts with 382 watts. It takes 360.0 watts to fully provision 12 ports at 30 watts per port (plus 6 watts to account for load fluctuations), leaving 22 watts to be returned to the pool of available watts.

Since a port requires 33 watts to power up a PoE+ device, there is not enough available power to power another device.
