1. Introduction

These Application Notes describe the Power Over Ethernet configuration of the ExtremeNetworks Summit X250e-48p Switch and Extreme Networks Summit X450e-24p Switch, to

support the Avaya 9608, 9611G, 9621G, and 9641G IP Telephones registered to Avaya Aura

Session Manager and Avaya Aura Communication Manager.

Power over Ethernet (PoE) allows both power and data to be simultaneously carried over

standard Ethernet cables. PoE-enabled Ethernet switches can supply power directly to Ethernetdevices, thereby simplifying installation and removing the need for separate power supplies for

those devices. The IEEE 802.3af standard defines the mechanisms for Power Sourcing

Equipment (PSE), such as PoE-enabled Ethernet switches, to detect, classify, and supply power

to Powered Devices (PDs), such as PoE-enabled IP telephones. The Extreme Networks SummitX250e-48p switch provides 48 ports with PoE. The Extreme Networks Summit X450e-24p

switch provides 24 ports with PoE.

The 96x1 IP telephones are part of the 96xx family. They build on existing 96xx functionalityand user interface concepts. They run on a Wind River Linux Operating System and provide

better performance at a lower cost than the 96xx phones.

The 96x1 IP telephones include the 9608, 9611G, 9621G, and 9641G models. The following

3. Configuration of the Avaya IP TelephonesThere is no configuration requirement on the Avaya IP telephones to use PoE. For details onconfiguring Avaya Aura Session Manager, Avaya Aura Communication Manager, or Avaya

IP Telephones, consult References [1], [2], and [3].

4. Configuration of the Extreme Network SwitchesThe configuration steps below focus on the basic commands used for PoE on the Extreme

switches. Additional configuration details are available in the ExtremeXOS Command ReferenceGuide [4].

The Extreme Networks Summit X250e-48p and Extreme Networks Summit X450e-24p useExtreme XOS, and therefore the commands listed here apply to both switches.

PoE is enabled by default in the Extreme Networks Summit switches. If the configuration has

changed, PoE can be enabled on a port by using the command enable inline-power port. Theexample below enables PoE on port 19.

X250e- 48p # enabl e i nl i ne- power por t 19

If the port parameter is not specified, PoE will be enabled on all the ports.

X250e- 48p # enabl e i nl i ne- power

The command disable inline-power can be used to disable PoE on a port when a device

attached to it does not use PoE. The example below disables PoE on port 19.

X250e- 48p # di sabl e i nl i ne- power port 19

If the port parameter is not specified, PoE will be disabled on all the ports.

X250e- 48p # di sabl e i nl i ne- power

5. ObservationsThe following table shows power classification and measured power reported by Extreme

Networks Summit X450e-24p and Extreme Networks Summit X250e-48p switches. IPTelephones were connected directly to the switch. Cables of different lengths were used. Cable

length and impedance affects power usage, so the measurements listed here may vary based on

the cable used. In addition, the power measured for a given port may vary slightly from time totime but will stay in a small range. The power measurements reported here are either the most

reported value or the average value and are only for reference purposes.

6. Verification StepsWhen the IP Telephones are properly powered, the IP Telephones should register and receive

dial tone when they are off-hook. If the IP Telephones are not receiving power, check the cableused and check the port configuration to ensure PoE was enabled on the port.

The show inline-power config port command can be used to see if PoE is enabled on a port.The example below shows PoE is enabled on port 19.

The show inline-power info port command can be used to see the amount of power being

delivered and the Class. The example below shows this information for port 19.
