Cisco Cisco Aironet 1200 Access Point Notas de publicación

This section describes limitations and restrictions for the access point.

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 should try to reset the unit to factory defaults using the :resetall 
command in the CLI; see the 

 of the Cisco 

Aironet 1200 Series 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 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:

All three indicators are steady 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 IEEE 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 IEEE 802.1x protocol.

with which they comply.
