General Poe Operation - HP ProCurve 6400cl Series Management And Configuration Manual

Power Over Ethernet (PoE) Operation for the Series 5300xl Switches
For information on installing an HP ProCurve Switch xl PoE Module
■
(J8161A), refer to the HP ProCurve Switch xl Modules Installation
Guide provided with the module.
To help you plan and implement a PoE system in your network, refer
■
to edition 2 or later of the PoE Planning and Implementation Guide,
which is available from either of the following sources:
• The Documentation CD-ROM (version 3.6 or greater) shipped with
your Switch Series 5300xl device after April, 2004.

General PoE Operation

Configuration Options
In the default configuration, all 10/100Base-TX ports on an xl PoE module
installed in the switch are configured to support PoE operation. You can:
■ Disable or re-enable per-port PoE operation on individual ports to
help control power usage and avoid oversubscribing PoE resources.
■ Configure per-port priority for allocating power in case a PoE module
becomes oversubscribed and must drop power for some lower-
priority ports to support the demand on other, higher-priority ports.
Configure one of the following:
■
• A global power threshold that applies to all modules on the switch.
This setting acts as a trigger for sending a notice when the PoE power
consumption on any xl PoE module installed in the switch crosses
the configured global threshold level. (Crossing the threshold level in
either direction—PoE power usage either increasing or decreasing—
triggers the notice.) The default setting is 80%.
• A per-slot power threshold that applies to an individual xl PoE module
installed in the designated slot. This setting acts as a trigger for
sending a notice when the module in the specified slot exceeds or
goes below a specific level of PoE power consumption.
