Power Over Ethernet (PoE) Operation
Configuring PoE Operation
Disabling or Re-Enabling PoE Port Operation
Enabling Support for Pre-Standard Devices
The ProCurve switches covered in this guide also support some pre-802.3af

model.
Syntax : [no] interface < port-list > power-over-ethernet
Re-enables PoE operation on
< port-list >
and restores the priority
setting in effect when PoE was disabled on
< port-list >
. The
no
form
of the command disables PoE operation on
< port-list >
. (Default:
All PoE ports on the module are initially enabled for PoE
operation at
Low
priority. If you configure a higher priority, this
priority is retained until you change it.)
Note : Disabling all ports on a module allows the 22W of
minimum PoE power allocated for the module to be recovered and
used elsewhere. You must disable ALL ports in the module for this
to occur.
Syntax : [no] power-over-ethernet pre-std-detect
Detects and powers pre-802.3af standard devices.
Note : This is enabled by default.
