Managing Power over Ethernet (PoE)

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.
Note. PoE units support different wattage power supplies. If unlike power supplies are mixed or if an
unsupported power supply is used, a console message and a trap are generated.

PoE Class Detection

Powered devices can be classified into different classes as shown in the table below. Class detection
allows for automatic maximum power adjustment based on the power class detected. This will prevent the
switch from delivering more than the maximum power allowed based on a device's class.
During class detection, the switch will allocate the maximum amount of power allowed based on the class
detected. Once powered, if the device uses less than the maximum, the remaining power will be made
available for other devices.

Although class-detection is disabled by default, the OS6860 still provides power to incoming PDs (if
available in the power budget). However, to strictly enforce class detection as specified in the 802.3at
standard, class detection must be enabled using the
Enabling class detection will reset all PoE ports on the chassis.

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
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 slot 2/1 service start
If power to a particular port has been administratively disconnected, you can reactivate power to the port
using the lanpower port admin-state
-> lanpower port 2/1/1-24 admin-state enable
