The following table lists the defaults for PoE configuration:

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. 

Note. PoE units support either 510W or 360W power supplies. If unlike power supplies are mixed or if an 
unsupported power supply (such as a 120W power supply) is used, a console message and a trap are 
generated.

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 

 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 3

If power to a particular port has been disconnected via the 

 command, you can reactivate 

power to the port by specifying both the slot and port in the command line. For example:

-> lanpower start 3/11

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 

 command. To initially 

activate PoE, you must use the lanpower start slot syntax only, as described above.
