CATERR_N:Sensor Failure Asserted

[Simon5923]

Hi,

I received a minor warning on a server displaying CATERR_N:Sensor Failure Asserted.

Looking at the SEL log I can see this happening like 1-4 times a year since the server was first initialized but has now occurred multiple times in the last few days. Should I be worried?

As far as I understand, this relates to the CPU and/or the memory of the server?

Thanks,

That alert can be generated in association with DIMM issues, so it makes sense that you appear to have a batch of DIMM alerts going on around that same time.

I would open a TAC case to get the DIMM issue corrected/evaluated, and see if the CATERR_N issue disappears.

The DIMM alert may/may not be an issue, as it seems to be hitting a marginal voltage threshhold.

Hello Simon, 

I am having the same issue with one of the Server. 

Appreciate if you share that how were you able to solve this issue?
