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.
