Description
We can check the current reported output from the MPX 8XXX device using the command
> stat system detail
CPU Fan 0 Speed (RPM) 4050
CPU Fan 1 Speed (RPM) 4050
System Fan Speed (RPM) 4050
System Fan 1 Speed (RPM) 4200
System Fan 2 Speed (RPM) 4200
CPU 0 Temperature (Celsius) 100
CPU 1 Temperature (Celsius) 0
Internal Temperature (Celsius) 56
Power supply 1 status NORMAL
Power supply 2 status NORMAL
Resolution
As per the output of command "ipmitoo_sel_elist" output shows that cpu has burned up.
ipmitool_sel_elist.out
1 | 08/29/2014 | 21:30:49 | Temperature CPU Temp | Upper Non-critical going high | Reading 100 > Threshold 95 degrees C
2 | 08/29/2014 | 21:30:49 | Temperature CPU Temp | Upper Critical going high | Reading 100 > Threshold 98 degrees C
3 | 08/29/2014 | 21:30:49 | Temperature CPU Temp | Upper Non-recoverable going high | Reading 100 > Threshold 100 degrees C
Device has to be RMA'ed if this issue is observed.
Looking at this screenshot we see that CPU reports "nr" that is because *upper non-recoverable* threshold value for this sensor is 100.
