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
