Several AP1200s were recently installed at a customer site. They were all connected to Lucent switches and powered using power injectors. In one building the access points all lost their identity one day. They were not accessable through web management at all. If the access point was rebooted it would come up fine. All of the configurations were still on it when it came back up. This following day the same thing happened in another building on the site which is on a different network segment. Is there anything that would cause the access points to do this? I am at a loss and the customer is wondering as well.
It could be the following error message and open Caveat from Cisco AP1200 release notes:
CSCdy128761200 series access points sometimes lock up under extremely large bursts of Ethernet traffic. Reboot the access point if it locks up.
Maybe get a LAN analyser and confirm the Lucent switches are OK
Otherwise what firmware are you using? Some early releases may be a little buggy. Try the latest, 11.54T on one AP1200 and see if this resolves your issue, the firmware and release notes can be downloaded here:
