1 Introduction This chapter provides an overview of: ■ Power over Ethernet (PoE/PoE+). ■ A list of reasons why you might want to implement PoE/PoE+ in your network environment. ■ How PoE/PoE+ supplies power over twisted pair cable. ■ The capabilities of the HP devices used to provide PoE/PoE+.
PAGE 14
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.
PAGE 15
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.
PAGE 16
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.

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.

2 Operating Rules Introduction This chapter discusses the operating rules and characteristics of the HP networking product capabilities, switches, and external power supplies, including an overview of how PoE power is configured on these devices, and how the switches prioritize PoE provisioning to their network ports.
PAGE 26
Operating Rules Configuring PoE/PoE+ Power Using the CLI 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 for your switch at: www.hp.
PAGE 27
Operating Rules PoE Power Characteristics 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%.
PAGE 28
Operating Rules PoE Power Characteristics Table 2-1. Power Usage Class Usage Minimum Power Levels at Output of PSE Range of Maximum Power required by the PD 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.

Operating Rules Provisioning Power for PoE Provisioning Power for PoE Many of the PoE/PoE+ switches discussed in this manual support an external power supply (EPS) that can provide either redundant or extra PoE/PoE+ power. It is important to understand how PoE power is provisioned in order to use these EPSs efficiently. The following chapters will discuss this in detail for each of the products.

Planning and Implementation for the HP 2610-PoE Switches Planning the PoE Configuration 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. HP 2610-24-PPoE Switch Configurations The tables in the example configurations contain entries that show the PoE power available when the HP 2610-24-PPoE Switch is used alone.
PAGE 50
Planning and Implementation for the HP 2610-PoE Switches Planning the PoE Configuration ■ ■ 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.

Planning and Implementation for the HP 5400zl/8200zl Switches Introduction 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.

Planning and Implementation for the HP 5400zl/8200zl Switches Introduction PoE Chassis Switch 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.
PAGE 129
Planning and Implementation for the HP 5400zl/8200zl Switches Introduction Switch 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.

Planning and Implementation for the HP 5400R zl2 Switches Configuration Examples fails, the J9828A can keep the switch running but cannot supply all the PoE power that the J9829A was supplying. Therefore you need to plan very carefully when using this configuration. In a system with mixed power supplies, failover is calculated based on the largest power supply failing.

Planning and Implementation for the HP 5400R zl2 Switches Configuration Examples Standard J9829A Configurations This configuration (Figure 14-11) is an example of two power supplies supplying 900 watts each for a maximum of 1664 watts to a fully-loaded HP 5412R zl2 Switch with 288 ports. Therefore out of the total 288 available ports, 107 can be powered at 15.4 watts each or all ports could be used at 4.0 watts. Figure 14-11.

Planning and Implementation for the HP 5400R zl2 Switches Configuration Examples This configuration could be redundant for PoE power up to 900 W. The upper 6 slots would stay up if they were the ports supplying the PoE power and the lower 6 slots were used for other than PoE power. One power supply has enough power to supply system power to the upper 6 slots and keep the switch up and running. And as long as the 900 watts of PoE power is not exceeded, then the top 6 modules would remain powered.

Planning and Implementation for the HP 5400R zl2 Switches Configuration Examples In this example, one J9829A could be held in reserve to provide redundant power for the other J9829A since they are equal in power. However if the J9828A should fail there would be no redundancy for that power supply unless you borrow power from the reserve J9829A. If you do that and the primary J9829A fails, there will not be enough power to fully backup the failed J9829A.

15 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.
PAGE 208
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.
