SNMP PSU Values

Hi,

Quick question, I’m monitoring PSU status with SNMP. I can see that a value of 1 means the PSU is OK. Can anyone confirm the value of a failed PSU? Is it 0, 2 or other? Is there anyway to look this up?

Also, when it comes to things like fan speed or temperature readings, is there anywhere that defines acceptable thresholds? Just need to know what values to trigger alerts at.

Many thanks.

Anyone have information on this? Thanks.
