Configuring Power over Ethernet Parameters
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 .
For a tutorial that provides a step-by-step walk through a typical PoE software configuration, refer to
page 3-32 .
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 ports in a slot, enter the corresponding slot number only. For example:
lanpower start 3
Note. You cannot activate PoE for more than one slot at a time. Also, a valid PoE module (OS7-ENI-P24)
must be installed in the corresponding slot position.
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 3/11
Parameter Description Command(s) Default Value/Comments
PoE operational status lanpower start or lanpower stop Disabled
Total power allocated to a port lanpower power 15400 milliwatts
Total power allocated to a slot lanpower maxpower 210 watts
Power priority level for a port lanpower priority low
The capacitor detection method lanpower capacitor-detection Disabled
Power supply redundancy lanpower redundant-power Disabled (see important note on
page 3-24 )
Priority disconnect status lanpower priority-disconnect Enabled
