Cooling system failure
When the temperature inside the router exceeds 75°C (167°F), the following information appears on the
configuration terminal:
%May 14 21:37:35:271 2010 H3C DRVMSG/3/Temp2High:
Environment temperature too high in Slot 0, index is 2.
#May 14 21:37:35:713 2010 H3C DEV/1/BOARD TEMPERATURE UPPER:
Trap 1.3.6.1.4.1.2011.2.23.1.12.1.16<hwBoaardTemperatureHigher>: frame Index is 0, slot
Index 0.0
%May 14 21:37:35:713 2010 H3C DEV/4/BOARD TEMP TOOHIGH:
Board temperature is too high on Frame 0 Slot 0, type is MPU.
The output shows that the temperature inside the router has exceeded the upper threshold 75°C (167°F).
In this case, the fans of the router will rotate at full speed.
Generally, after the fans rotate at full speed for a certain period, the temperature inside the router will
drop below 75°C (167°F), and the following information appears on the configuration terminal:
%May 14 22:25:17:804 2010 H3C DRVMSG/3/TempHOK:
Environment temperature recovered from OT in Slot 0, index is 2.
#May 14 22:25:18:713 2010 H3C DEV/1/BOARD TEMPERATURE NORMAL:

%May 14 22:25:18:713 2010 H3C DEV/4/BOARD TEMP NORMAL:
Board temperature changes to normal on Frame 0 Slot 0, type is MPU.
The output shows that the operating temperature of the router restores to normal state.
When exceptions occur, the temperature inside the router might exceed 90°C (194°F), and the following
information appears on the configuration terminal in this case:
%Jun 25 14:38:45:444 2010 H3C DRVMSG/3/TempCritical:
CPU temperature critical in Slot 3, index is 1.
At the same time, the ALM LED of the MPU is red, which indicates that the temperature inside the router
is abnormal.
