Disabling or Re-Enabling PoE Port Operation

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 are initially enabled for PoE operation at Low priority.
If you configure a higher priority, this priority is retained until
you change it.)
To cycle the power on a PD receiving power from a PoE port on the switch,
disable, then re-enable the power to that port. For example, to cycle the power
on a PoE device connected to port 1:
ProCurve(config)# no interface 1 power-over-ethernet
ProCurve(config)# interface 1 power-over-ethernet
Configuring the PoE Port Priority Level
Using a priority class method, you can assign a power priority of Low (the
default), High, or Critical to each enabled PoE port.
Syntax: interface < port-list > power-over-ethernet [ 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 1-24 have a priority level of critical, port 1 has
priority over ports 2-24.
If there is not enough power available to provision all active PoE
ports at a given priority level, then the lowest-numbered port will
be provisioned first. 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.
