Solved: 2950G log shows Internal POWER supply is FAULTY

mike.purdon · ‎02-25-2010

Hi Everyone, I've a 2950G that from time to time logs the Internal POWER supply is FAULTY message. The switch is operating normally, it's not rebooting and isn't connected to an RPS. The IOS version is .121-22.EA8a. Has anyone any idea whether this is a genuine hardware problem or is it software related?

best wishes, Mike

Hi Mike,

If 'show env all" does not presents any PS failures, then it could be some cosmetic issue.

For example, could be due to the not fully correct changes in the code

done under CSCsb73608 "2950 does not generate error message when power supply fails",

which in turn were corrected in 12.1(22)EA9 under CSCse84332.

Thanks,

Sergey

Hi, the code upgrade didn't fix the problem, the switch has continued to work but the CLI showed psu fault. We plan to replace the switch just in case the psu suddenly dies, best wishes, Mike
