Power Over Ethernet (PoE) Operation

Configuring PoE Operation

Configuring PoE Operation

In the default configuration, PoE support is enabled on the PoE ports. 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

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 to be recovered and used elsewhere. You must disable ALL ports for this to occur.

Enabling Support for Pre-Standard Devices

By default, all ProCurve PoE switches support 802.3af-standard PDs. In addition, the switches covered in this guide have the ability to supply power to pre-802.3af-standard devices, such as legacy (non-standard) IP phones.

When the switch is in legacy detection mode, the detection signature range is expanded beyond the IEEE specification. This allows non-compliant devices to be powered.
