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.

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 poe-
shutdown port x” command enables PoE on a port. The screen below shows sample commands
to disable/enable PoE on port 1.
