Alarm Information
Chassis Serial#:12,Blade:blade3,Sensor:CPU1 Memory,Event:Critical overtemperature,Severity:Deassertion [Major],Event Code:0X0C8AFFFF
Handling Process

1, We checked the real temperature in the IT room and found that it is normal.

2, Because the temperature is normal, it is possible that it is the false alarm that caused by software.

3, checked the version of the MM910, it is not the latest.

 

 

4, check the latest version MM910 release notes, and we found that this issue was fixed in the MM910 V516

 

 



Root Cause

This is the false alarm and will be fixed in the MM910 v516

Solution

Upgrade the MM910 to the V516.  And CPLD version of CH140 V3 to be V100
