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 stan-
dard, class detection must be enabled using the lanpower slot class-detection command.
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 lanpower slot service 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 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 command. For example:
-> lanpower port 2/1/1-24 admin-state enable
Note. You cannot use the lanpower port admin-state command to initially activate PoE on a port. This
syntax is intended only to reactivate power to those that have been disconnected via the lanpower slot
service command. To initially activate PoE, you must use the lanpower slot service command as
described above.
