Limitations and Restrictions
Removing Power During Firmware Update Can Corrupt Radio Firmware
When you update the firmware on an access point or bridge, allow the unit to finish its start-up sequence 
before removing power. If you update the firmware and remove power before the unit finishes the 
start-up sequence, the radio firmware might be corrupted, making the unit inoperable. If the radio 
firmware is corrupted, the radio indicator (the bottom of the three indicators on top of the access point 
or bridge) lights solid red, and the following error message appears when the access point or bridge starts 
up:
Failed to start driver for port “awc0” (errno=0x006d0002)
If the radio firmware is corrupted, you must return the unit to Cisco for service.
