Power Over Ethernet (PoE/PoE+) Operation
Configuring PoE Operation
Configuring PoE Operation
In the default configuration, PoE support is enabled on the ports in a PoE
module installed on the switch. The default priority for all ports is Low and
the default power notification threshold is 80 (%).
Using the CLI, you can:
■ Disable or re-enable PoE operation on individual PoE ports
■ Enable support for pre-standard devices
■ Change the PoE priority level on individual PoE ports
■ Change the threshold for generating a power level notice
■ Manually allocate the amount of PoE power for a port by usage, value,
or class.
■ Allocate PoE power based on the link-partner’s capabilities via LLDP.
Disabling or Re-Enabling PoE Port Operation
Syntax: [no] interface <port-list > power-over-ethernet
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 PoE ports are initially enabled for PoE operation at Low
priority. If you configure a higher priority, this priority is
retained until you change it.)
Note: For PoE, disabling all ports allows the 22 W of minimum
PoE power or 38 W for PoE+ power allocated for the module to be
recovered and used elsewhere. You must disable ALL ports for this
to occur.
Enabling Support for Pre-Standard Devices
The ProCurve switches covered in this guide also support some pre-802.3af
devices. For a list of the devices supported, refer to the FAQs for your switch
model.
Syntax: [no] power-over-ethernet pre-std-detect
Detects and powers pre-802.3af standard devices.
Note: This is enabled by default.
