I would like to inform you that this is what we know as a cosmetic bug.
This message is not correct since the unit does not support RPS and does not
have any internal power supplies. This occurs under all conditions and these
logs are erroneously indicating an error condition that does not exist.
There is no workaround for this behavior. The logs may be ignored.

 

2. I would request you to try reloading the switch, else we can replace the
switch.

I would like to inform you that if 2950 doesnt have RPS connected and sh env shows no RPS connected/supported, then this is a cosmetic bug.

CSCse84332 Unexpected RPS failure message on bootup

This message is not correct since the unit does not have RPS and does not have any internal power supplies. This occurs under all conditions and these logs are erroneously indicating an error condition that does not exist.
There is no workaround for this behavior. The logs may be ignored.

Try reloading the switch, else in worst case, replace the switch.

Hi

The error massage is h/w fault message in power part. but I saw message when the switch is inaccurate movement.

So if you can turn off and on the switch. You check the log. You will find this message again.

You have to support cisco tech support team. Because the switch is failed power part.

And refer below the link. The document is message guide.

Yesterday I started to receive

"ENVIRONMENT-3-RPS_FAILED: Faulty internal power supply detected" messages on one of my 2950.

NO RPS is connected to the 2950. I am a little bit confused: is this error message relate to the RPS module of the 2950, or does it relate to the physical AC power supply builtin to the device?

I hardly believe this error relates to the built-in AC power supply, as in case it has an issue, it would just simply crash the device (or even cut the power completely) without letting the device send out any scream, am I right? It this some kind of pre-fail diagnostic message?

pasztor.richard · ‎09-09-2011

Forgot to say: its running the most recent IOS for 2950: 12.1(22)EA14

pasztor.richard · ‎04-25-2012

Even if nobody replied with anything useful, I wanted to give another headsup to this issue (hoping someone provides feedback): since 2 days, it started to log this error message every 10 seconds. The switch is still running thoug, so I am not sure if thats only a pure software bug, or this indeed relates to the hardware (in which case the switch should have already crashed without having time to report this issue).

I am currently also seeing same issue at one of our site where we having power issue and lost complete power to cisco 3750 but where 2950 showing same thing

You need to contact Cisco TAC and get the part replaced.

I think most 2950's are EOL at this point so you should probably look for a new switch . You could call the TAC to verify.
