1. Introduction
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 Ethernet
devices, 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 Nortel 5520-24T-PWR
switch provides 24 ports with PoE.
The Avaya product configurations addressed by these Application Notes are shown in Figure 1.
The following Avaya powered devices were covered:

3. Configuration of the Avaya endpoints
There is no configuration requirement on the Avaya endpoints to use PoE. For details on
configuring Avaya Communication Manager Servers, Gateways, or Endpoints, consult the
Administrator’s guide [1].
4. Configuration of the Nortel switch
The configuration covered here is specific to PoE and does not include configuration of other
features available in the Nortel switch. Consult the Nortel configuration manual [2] for additional
configuration details.
The default configuration on the Nortel switch is sufficient to enable the Avaya IP Telephones to
receive Power over Ethernet, as long as PoE is enabled on the port.
A serial port on a PC was used to connect to the serial port of the Nortel switch. A standard
terminal emulator was running on the PC. When connected to the switch, the main screen
appears and displays the switch model and software versions. The user must press “Ctrl-Y” to
enter the menu configuration screen shown below.

Use the arrow keys to move down to “Command Line Interface…” and press the “Enter” key to
access the Command Line Interface (CLI).
PoE can be enabled/disabled on a per port basis. Type “enable” followed by the “Enter” key.
Type “config t” followed by the “Enter” key. Type “interface fastethernet all” followed by the
“Enter” key. The “poe poe-shutdown port x” command disables PoE on a port. The “no poeshutdown port x” command enables PoE on a port. The screen below shows sample commands
to disable/enable PoE on port 1.

5. Observations
Table 1 shows the detected class and power allocated from the Nortel 5520-24T-PWR switch. IP
Telephones 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. The power measurements reported here are only for reference purposes.

Table 1: Power Measurements
* The Avaya one-X Value Edition 1603 IP Telephone with PoE Splitter is a Class 2 Powered
Device. It was observed that the Nortel 5520-24T-PWR was not able to properly detect its class.
The switch reported different classes for the device, but showed power measurements in the
expected range, and was able to properly provide power to the device. The class for all other
devices was properly detected. It should be noted that the Avaya one-X Value Edition 1603 IP
Telephone with PoE Splitter has been tested with other PoE switches and its class was properly
detected.
6. Verification Steps
The following commands can be used with the Nortel 5520-24T-PWR to display the device class
detected and power provided.

When 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 cable
used and check the port configuration to ensure PoE was enabled on the port.
