Cisco 39xx CPU temperature thresholds

Hi,

What are proper CPU temperature thresholds for Cisco 39xx series? What are the values and what are the states?

I'm avare of "normal" and "critical" state when the cpu reaches 115 C. I don't know which temperature is not "normal" and still not criticall...

TIA.

Re: Cisco 39xx CPU temperature thresholds

The output of "show environment" can report an "Abnormal" state for a temperature which is the non-critical state you are asking about.  The threshold changes per platform.  If you are asking about the 3900 and not the 3900e series routers, then there is no Abnormal state. The reading will be either Normal or Over-temperature (at 115 degrees).  These thresholds aren't documented publicly.
