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:
•
Max 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%
)
•
Pre-standard Detect
: Shows whether PoE for
pre-802.3af-standard powered devices is enabled on the
switch. (Default:
Off
; shows
On
when PoE for
pre-802.3af-standard powered devices has been enabled.)
For example, in the default PoE configuration, when the switch is running
with several ports supporting PD loads,
show power-management
displays data
similar to the following:
ProCurve(config)# show power-management
Status and Counters - System Power Status
Pre-standard Detect : Off
Maximum Power : 406 W
Operational Status : On
Power In Use : 75 W +/- 6 W Usage Threshold (%) : 80
