General Poe Operation - ProCurve 6200yl Management And Configuration Manual

General PoE Operation

The CLI commands discussed in this chapter apply to both the Series 5400zl
and Series 3500yl switches. For additional PoE configuration information for
the Series 5400zl and Series 3500yl switches, refer to the PoE Planning and
Implementation Guide, which is available from the ProCurve Networking
web site at www.procurve.com. (Click on technical support, then Product manu-
als (all)).
Configuration Options
In the default configuration, all Gig-T ports on the PoE module in a Series
5400zl 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 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 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.
