We had an issue Monday morning where a customer's site lost power for an extended period of time.
When power cameback up, the UC500 would not boot up. Here are our technician's notes:
" I connected to the UC500 via console port and the box was running, but it was asking me if i wanted to run the initial configuration, so the box lost the configuration which was stored in the startup NVRAM. We had a backup of the config on the flash car, so I copied that to startup and reloaded and everything came back up. However, I had some weird issues with some static NATs, not sure why, but after reloading the system again, they started workign again."
This client is running 20T...
What I want to know is: is this normal? Shouldn't a UC500 withstand a power outtage? What should have been the expected behavior?
I have a TAC case open, but wanted the Cisco BU's ideas/advice/input...not just a TAC response.
We had the exact same thing occur and found it was due to a bug in the IOS we were using. After upgrading to a later version (22T I think) this problem stopped.
