Configuring Power Using the CLI

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 configure the access point to
operate with older switch software using the following Cisco IOS CLI command:
[no] power inline negotiation {prestandard source | injector H.H.H}
(where H.H.H is the MAC address of the switch port to which the access point is connected)
You can use this Cisco IOS CLI command to inform the access point of the following:
•
•
Refer to
corresponding Cisco switch power command.
If the access point receives power through PoE, the output current of the power sourcing equipment
Caution
(PSE) cannot exceed 400 mA per port. The power source must comply with IEEE802.3af or IEC60950
for limited power sources.
After completing your configuration changes, you must remove the serial console cable from the access

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.
