Cisco Cisco Aironet 1200 Access Point Notas de publicación

This section describes limitations and restrictions for 1200 series access points.

When you update the firmware on an access point, 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) is red continuously, and the following error message appears when the access point starts 
up:

Failed to start driver for port “awc0” (errno=0x006d0002)

The access point should recover from this error automatically.

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 continuously green and the top and bottom indicators are off, indicating that 
the access point is updating the radio firmware. 

When the middle indicator blinks or the top and bottom indicators blink, you can shut off 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 version 4.16, the access point should be configured to use Draft 8 
of the 802.1x protocol.
