Troubleshooting the Cooling System

Symptom
When the temperature inside the firewall exceeds 75°C (167°F), the following information appears on
the configuration terminal screen:
%May 14 21:37:35:271 2007 H3C DRVMSG/3/Temp2High:

%May 14 21:37:35:713 2007 H3C DEV/4/BOARD TEMP TOOHIGH:
Board temperature is too high on Frame 0 Slot 0, type is MPU.
This indicates that the temperature inside the firewall exceeds the upper limit 75°C (167°F). In this case,
the fans should run at full speed.
Normally, when the temperature inside the firewall comes down below 75°C (167°F), the following
information appears on the configuration terminal screen:

%May 14 22:25:18:713 2000 H3C DEV/4/BOARD TEMP NORMAL:
Board temperature changes to normal on Frame 0 Slot 0, type is MPU.
This indicates the temperature in the firewall has come back to the normal range.
If the temperature inside the firewall keeps rising and exceeds 90°C (194°F), the following information
appears on the configuration terminal screen:
%Jun 25 14:38:45:444 2007 H3C DRVMSG/3/TempCritical:
CPU temperature critical in Slot 3, index is 1.
The ALM LED of the MPU is red. This indicates that the temperature inside the firewall is abnormal.

Check that:
The fans are running normally.
The working environment of the firewall is well ventilated.
Use the display environment command to check whether the temperature in the firewall keeps
rising.
