Configuring PoE Operation
In the default configuration, PoE support is enabled on the Gig-T ports in a
PoE module installed on the switch. The default priority for all ports is Low
and the default power notification threshold is 80 (%). Using the CLI, you can:
■ Change the PoE priority level on individual PoE ports
Disable or re-enable PoE operation on individual PoE ports
■
Change the threshold for generating a power level notice
■

Changing the PoE Port Priority Level

Syntax: interface < port-list > power [ critical | high | low ]
Reconfigures the PoE priority level on < port-list >. For a given level,
ports are prioritized by port number in ascending order. For
example, if ports A1-A24 have a priority level of critical, port A1
has priority over ports A2-A24.
If there is not enough power available to provision all active PoE
ports at a given priority level, then the lowest-numbered port at that
level will be provisioned first, starting with module A, then B, C,
and so on. PoE priorities are invoked only when all active PoE ports
cannot be provisioned (supplied with PoE power).
• Critical: Specifies the highest-priority PoE support for
< port-list >. The active PoE ports at this level are provisioned
before the PoE ports at any other level are provisioned.
• High: Specifies the second priority PoE support for
< port-list >. The active PoE ports at this level are provisioned
before the Low priority PoE ports are provisioned.
• Low (the default): Specifies the third priority PoE support for <
port-list >. The active PoE ports at this level are provisioned only
if there is power available after provisioning any active PoE
ports at the higher priority levels.
You can use one command to set the same priority level on PoE
ports in multiple modules. For example, to configure the priority
to High for ports c5-c10, C23-C24, D1-D10, and D12, you could use
this command:
ProCurve(config)# interface c5-c10,c23-c24,d1-
d10,d12 power high
