WC8180 Wireless LAN Controller with 64 ap 8120. These APs are connected to Nortel 2550T Switch, Software version 1.1.0.133 all AP injector energized with Poe. All 3 years old.
Lately they have fallen 10 antennas. All stopped working without warning.
Someone had a problem working with these antennas.? you could check to prevent others have faults.?

I would appreciate help.

Do u mean to say, the Antennas are broken and APs stopped working? I think it might be a hardware issue. Antennas are required for 8120 Ap to work properly. You would wanted to replace it with an RMA process with Avaya.
