General PoE Operation

For additional PoE configuration information for the ProCurve 8212zl switch,
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 manuals (all)).

Configuration Options

In the default configuration, all Gig-T ports on the PoE module in a ProCurve
82121zl 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.
