Power Over Ethernet (PoE) Operation

Configuring PoE Operation

Cycling Power on a Port

Simply disabling a PoE port does not affect power delivery through that port.

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 on a

switch covered in this guide:

ProCurve(config)# no interface 1 power

ProCurve(config)# interface 1 power

Syntax: interface [e] < port-list > power [ critical | high | low ]

Reconfigures the PoE priority level on < port-list >. For a given

level, the switch automatically prioritizes ports by port

number (in ascending order). 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, and so on. The switch invokes configured

PoE priorities only when it cannot provision all active PoE

ports.

• Critical: Specifies the highest priority PoE support for < port-

list >. The switch provisions active PoE ports at this level

before PDs connected to any other ports.

• High: Specifies the second highest priority PoE support for

< port-list >. The switch provisions active PoE ports at this

level before PDs connected to Low-priority ports.

• Low (the default): Specifies the lowest priority PoE support

for < port-list >. The switch provisions active PoE ports at

this level only if there is power available after provisioning

any active PoE ports at the higher priority levels.
