Power over Ethernet Defaults
The following table lists the defaults for PoE configuration:
Understanding and Modifying the Default Settings
The sections below provide information on each of the key components within the Power over Ethernet
software. They include information on PoE-related CLI commands. For detailed information on PoE-
related commands, refer to the OmniSwitch CLI Reference Guide.
Setting the PoE Operational Status
Enabling PoE
By default, Power over Ethernet is administratively enabled in the switch’s system software. However, in
order to physically activate PoE, you must issue the lanpower start command on a slot-by-slot basis
before any connected PDs will receive inline power.
To activate power to PoE-capable in a switch, enter the corresponding slot number only. For example:
-> lanpower start 1
If power to a particular port has been disconnected via the lanpower stop command, you can reactivate
power to the port by specifying both the slot and port in the command line. For example:
-> lanpower start 1/1
Note. You cannot use the slot/port syntax to initially activate PoE on a port. This syntax is intended only
to reactivate power to those that have been disconnected via the lanpower stop command. To initially
activate PoE, you must use the lanpower start slot syntax only, as described above.
