arg3

Port No. of the optical module, for example, 1 or 2.

arg4

Current reading of the sensor.

arg5

Alarm threshold.

Impact on the System

Services related to the optical module are affected.

Possible Causes

  • A fan module is faulty.
  • The ambient temperature exceeds the normal range.
  • The air inlet or outlet is blocked.
  • The optical module is faulty.

Procedure

  1. Check whether there is a fan alarm.

    • If yes, go to 2.
    • If no, go to 3.

  2. Replace the fan module. Then, check whether the alarm is cleared.

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

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

    • If yes, go to 4.
    • If no, go to 5.

  4. 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 5.

  5. Check whether the server air inlet or outlet is blocked.

    • If yes, go to 6.
    • If no, go to 7.

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

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

  7. Replace the optical module. Then, check whether the alarm is cleared.

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