Disabling Or Re-Enabling Poe Port Operation - HP ProCurve 6400cl Series Management And Configuration Manual

Power Over Ethernet (PoE) Operation for the Series 5300xl Switches

Disabling or Re-Enabling PoE Port Operation

Syntax: [no] interface [e] < port-list > power
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 xl PoE ports on the module are enabled for PoE
operation at Low priority.)
Changing the Threshold for Generating a Power Notice
Syntax: power [slot < slot-identifier >] threshold < 1 - 99 >
This command specifies the PoE usage level (as a percentage of the
PoE power available on a module) at which the switch generates a
power usage notice. This notice appears as an SNMP trap and a
corresponding Event Log message, and occurs when an xl PoE
module's power consumption crosses the configured threshold value.
That is, the switch generates a notice whenever the power
consumption on a module either exceeds or drops below the specified
percentage of the total PoE power available on the module.
This command configures the notification threshold for PoE power
usage on either a global or per-module (slot) basis.
Without the [slot < slot-identifier >] option, the switch applies one
power threshold setting on all PoE modules installed in the switch.
For example, suppose slots A, B, and C each have an xl PoE module
installed. In this case, executing the following command sets the
global notification threshold to 70% of available PoE power.
HPswitch(config)# power threshold 70
With this setting, if an increasing PoE power demand crosses this
threshold on the module in slot B, the switch sends an SNMP trap
and generates this Event Log message:
Slot B POE usage has exceeded threshold of 70 %.
If the switch is configured for debug logging, it also sends the Event
Log message to the configured debug destination(s).
On any PoE module, if an increasing PoE power load (1) exceeds
the configured power threshold (which triggers the log message and
SNMP trap), and then (2) later decreases and drops below the
threshold again, the switch generates another SNMP trap, plus a
message to the Event Log and any configured Debug destinations.
