I have a ws-C2960XR-24ps-I switch with 2 slots for power supply's but only 1 power supply inserted.

So the switch is always logging an event : "%PLATFORM_ENV-1-FRU_PS_ACCESS: FRU Power Supply is not responding". When I try to disable it by running enter image description here

I get "power supply is not present" in response. Is there a way to disable that slot so it stops sending these log messages that there is a missing power supply?

sh env cmd

I just want the specific log to stop without keeping it from logging any issues with the slot that is in use.

  • Is the switch part of a stack? what IOS version is it running?

  • no it is not part of a stack, IOS version is Cisco IOS Software, C2960X Software (C2960X-UNIVERSALK9-M), Version 15.2(2)E3, R ELEASE SOFTWARE (fc3)

I suspect that this log message is not caused by the absence of the PSU but by an IOS bug (e.g. CSCuv53498 but there are more), so upgrading it may get rid of the messages.

Alternatively, configure the following to just hide the syslog messages:

logging discriminator FOO msg-body drops FRU Power Supply is not responding
logging buffered discriminator FOO

(replace "buffered" with other type of logging as required)

  • So now how do I apply this to the logs being sent to syslog server?
