Power over Ethernet Budget Managing Power over Ethernet (PoE)
page 4-6 OmniSwitch 6560 Hardware Users Guide December 2019
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 switch still provides power to incoming PDs (if avail-
able in the power budget). However, to strictly enforce class detection it must be enabled using the
lanpower slot class-detection command.
Enabling class detection will reset all PoE ports on the chassis.
Enabling 802.3bt
The OmniSwitch supports IEEE 802.3af, IEEE 802.3at on 2-pairs, IEEE 802.3at on 4 pairs with support
for classes 0, 1, 2, 3 and 4. Support for 60W, 75W and 95W per port is provided supporting IEEE 802.3at
on 4-pairs and enabling PoH using the lanpower 4pair command.
The OmniSwitch also supports IEEE 802.3bt with an additional two types and 4 classes listed in the table
above. IEEE 802.3bt can be enabled with the lanpower 8023bt command.
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
