Impact on the System

Overheating affects component performance and server operations.

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 hosting the air inlet temperature sensor is faulty.

Procedure

  1. Check whether the equipment room temperature exceeds the normal range.

  2. Reduce the equipment room temperature to the normal range. After 5 minutes, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 3.

  3. Check whether the server air inlet is blocked.

  4. Clear the blockage. After 5 minutes, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 5.

  5. Check whether there are empty slots in the server.

  6. Install filler panels in empty slots. Then, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 7.

  7. 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 is on the indicator plate in the left mounting ear. Replace the left mounting ear. For details, see "Replacing Parts" in the user guide. Then, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 8.
