Hi

Unfortunately It looks like a hardware problem, if you have Cisco contract (Smartnet), you should open a case with the Cisco TAC in order to see if a RMA process can be submitted to replace the switch.

Is this a 3750 switch? If so, what is the version of IOS?

I'd upgrade the IOS and see if there are any improvements. 12.2(50)SE train isn't necessarily a stable/reliable release.

Hi,

As Leo said, I´d suggest you to upgrade to the suggested IOS version. In regards to the PoE error messages, the problem could be related to CSCsw18530. Once you upgrade you can apply the "power inline port 2x-mode" command

Last occurance is on 14/9

From 14/9 no device was connected at Fa1/0/22

And the switch was fine up until today

20/9 the switch hang again. I was out of office. Can't perform check.

Someone restart the switch.

Once online i was able to show log and it shows

AAA-3-DROPACCTFAIL: Accounting record dropped, send to server failed: system

another bug it seem.

By the way, when switch hang, what usefull command can enter to collect/check/investigate the condition of the switch?
