Cisco Aironet 350 Series Bridges Incompatible with 340 Series Bridges
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.

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 steady red, and the following error message appears when the access point or bridge
starts up:

firmware is corrupted, the radio indicator (the bottom of the three indicators on top of the access point

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:
