4550T-PWR Toggle POE

You may want to disable POE, eg, for trunk ports, or if using external Avaya power bricks for IP phones.

Use the following commands in Interface Configuration mode:

From the command line:

config terminal
interface fastethernet XX
poe poe-shutdown | no poe-shutdown

From the web interface:

When multiple ports are selected (ctrl-click), double-click in the AdminEnable column, and select a value from the list:

- true to enable PoE for the port, or false to disable PoE for the port.

Example:

To disable POE on all switch ports:

Closet1#conf t
Closet1(config)#sh poe-port-status
