Примечания к выпуску для Cisco Cisco Aironet 350 Access Points

Cisco Aironet 340 and 350 Series Bridges can be connected to the same LAN segments, but they cannot 
communicate wirelessly. Although you can disable STP on non-root 350 series bridges, 350 and 340 
series bridges are not designed to interoperate. If you use both 340 and 350 series bridges on your 
network, make sure the 340 series bridges have radio bridge links only to other 340 series bridges, and 
that 350 series bridges have radio bridge links only to other 350 series bridges.

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 steady 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 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 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
