Power Over Ethernet (PoE) Operation

Viewing PoE Configuration and Status

Displaying the Switch’s Global PoE Power Status

Syntax: show power-management

Displays the switch’s global PoE power status, including:

• Maximum Power: Lists the maximum PoE wattage available to

provision active PoE ports on the switch.

• Power In Use: Lists the amount of PoE power presently in use.

• Operational Status: Indicates whether PoE power is available on

the switch. (Default: On ; shows Off if PoE power is not available.

Shows Faulty if internal or external PoE power is oversubscribed

or faulty.)

• Usage Threshold (%): Lists the configured percentage of available

PoE power provisioning the switch must exceed to generate a

usage notice in the form of an Event Log message and an SNMP

trap. If this event is followed by a drop in power provisioning

below the threshold, the switch generates another SNMP trap and

Event Log message. Event Log messages are also sent to any

optionally configured debug destinations. (Default: 80%)

For example, in the default PoE configuration, when the switch is running

with several ports supporting PD loads on the PoE module in slot A, show

power-management displays data similar to the following:

ProCurve(config)# show power-management

Status and Counters - System Power Status

Pre-standard Detect :On

Status and Counters - System Power Status for slot A

Maximum Power : 270 W Operational Status :On

Power In Use : 0 W +/- 6 W Usage Threshold (%) :80
