Configuring Power Using Controller CLI Commands

Intelligent Power Management support is dependent on the version of software resident in the Cisco
switch that is providing power to the access point. Each Cisco switch should be upgraded to support
Intelligent Power Management. Until the software is upgraded, you can use your controller to configure
the access point to operate with older switch software using these controller CLI commands:
1) config ap power pre-standard enable <ap>
2) config ap power injector enable <ap> <switch port MAC address>
Refer to your controller documentation for instructions on using these commands.
Note
You can use these controller CLI commands to inform the access point of the following:
•
•
If the access point receives power through PoE, the output current of the power sourcing equipment
Caution
(PSE) cannot exceed 400 mA per port.
Refer to
and the corresponding Cisco switch power command.

1. You should check the release notes for your Cisco power source to determine which Cisco IOS release supports Intelligent Power Management. Support
for Intelligent Power Management might not be currently available for your Cisco power source.
2. Power injector must be AIR-PWRINJ4.

where <ap> is the access point name on the controller
(where <ap> is the access point name on the controller
and <switch port MAC address> is the MAC address of the switch port to which the
access point is connected)
The Cisco switch does not support Intelligent Power Management but should be able to supply
sufficient power.
A power injector is being used to supply sufficient power and the Cisco switch does not support
Intelligent Power Management.
