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.
