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:

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.
You can safely remove power after a firmware update when the configuration management pages
reappear in the command-line or web-browser interfaces, or when the three status indicators on top of
the unit complete the following pattern:

When the middle indicator blinks or the top and bottom indicators blink, you can remove power.
EAP Authentication Requires Matching 802.1x Protocol Drafts
Note
This section applies to wireless networks set up to use LEAP. If you do not use LEAP on your
wireless network, you can skip this section.

Wireless client devices use Extensible Authentication Protocol (EAP) to log onto a network and generate
a dynamic, client-specific WEP key for the current logon session. If your wireless network uses WEP
without EAP, client devices use the static WEP keys entered in the Aironet Client Utilities.

without EAP, client devices use the static WEP keys entered in the Aironet Client Utilities.
If you use Network-EAP authentication on your wireless network, your client devices and access points
must use the same 802.1x protocol draft. For example, if the radio firmware on the client devices that
will associate with an access point is 4.16, then the access point should be configured to use Draft 8 of
the 802.1x protocol.
