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-PWRINJ3 or AIR-PWRINJ-FIB.

3.The Cisco switch uses Intelligent Power Management to inform the access point of the power injector being used.

4.Cisco switches that support Intelligent Power Management always configure the use of a power injector at the switch.

Follow these steps to issue the Cisco IOS command for your power scenario:

Step 1 Connect a PC to the access point console port and use a terminal emulator to establish a session with the access point (refer to the “Connecting to the Access Point Locally” section on page 3-20).

Step 2 From the global configuration mode (refer to the Cisco IOS Software Configuration Guide for Cisco Aironet Access Points), enter the command below that applies to your power configuration (see Table 3-2):

•power inline negotiation injector installed

•no power inline negotiation injector

•power inline negotiation prestandard source

•no power inline negotiation prestandard source

Step 3 Enter the write memory command to save the setting to the access point memory.
