ALM-0x12000001 Air Inlet Overtemperature (Chassis, Minor Alarm)
Description
Alarm message:
The air inlet temperature (arg1 degrees C) exceeds the overtemperature threshold (arg2 degrees C).
This alarm is generated when the air inlet temperature exceeds the overtemperature minor threshold.
This alarm is cleared when the temperature is within the normal range.
Alarm object: chassis
Possible Causes
The ambient temperature exceeds the normal range.
The air inlet is blocked.
Idle slots or spaces are not installed with filler panels.
The component holding the air inlet temperature sensor is faulty.
The location of the air inlet temperature sensor varies with the server model. For details, see the user guide of the server you use.
Procedure
- Check whether the equipment room temperature exceeds the normal range. The recommended temperature is less than 40°C (104°F).
- Reduce the ambient temperature in the equipment room by using air conditioners and fans (for example, turn down the air conditioners and increase the fan speed. When the air conditioners cannot work properly, open doors and windows for ventilation). After 5 minutes, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 3.
- Check whether the temperature in the cabinet exceeds the normal range.
- Clear the blockage and ensure that the cabinet is well ventilated. After 5 minutes, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 5.
- Check whether the server air inlet is blocked.
- Clear the blockage. After 5 minutes, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 7.
- Check whether there are empty slots in the server.
- Install filler panels in empty slots. Then, check whether the alarm is cleared.
If yes, no further action is required.
If no, go to 9.
- Replace the component where the air inlet temperature sensor is located. Then, check whether the alarm is cleared.
The location of the air inlet temperature sensor varies with the server model. For details, see the sensor list in the server user guide.
Replace the component where the air inlet temperature sensor is located.For details, see the server user guide.
If yes, no further action is required.
If no, go to 10.
