Cisco Cisco Aironet 350 Access Points Notas de publicación

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 continuously 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 should try to reset the unit to factory defaults using the :resetall 
command in the CLI; see Chapter 9 of the Cisco Aironet Access Point Software Configuration Guide for 
instructions on resetting the access point. If the unit cannot be reset to defaults, you must return the unit 
to Cisco for service.

You can safely shut off 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:

All three indicators are continuously green, meaning that the access point is beginning to update the 
firmware.

The middle indicator is steady green and the top and bottom indicators are off, indicating that the 
access point or bridge is updating the radio firmware. 

When the middle indicator blinks or the top and bottom indicators blink, you can remove power.

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. 

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, the access point should be configured to use Draft 8 of the 
802.1x protocol.
