Parameters

Name Meaning

N

Serial number of the RAID controller card.

No number is displayed if the server has only one RAID controller card.

Impact on the System

The components cannot operate stably, which shortens the service life of the server and increases power consumption. If the alarm persists, the server powers off or restarts, which interrupts services and causes data loss.

Possible Causes

  • The fan module is faulty.

  • The ambient temperature exceeds the normal range.

  • The air inlet or outlet is blocked.

  • Idle disk bays are not installed with hard disk fillers.

  • Air ducts are not installed properly.

  • The RAID card is faulty.

Procedure

  1. Check whether a low fan speed alarm is generated for the fan module.

    You can obtain alarm information in either of the following ways:
    • View alarm information on the Current Alarms page of the iBMC WebUI.
    • Run the ipmcget -d healthevents command on the iBMC CLI.
    • If yes, go to 2.

    • If no, go to 5.

  2. Remove and then reinstall the fan module. After 5 minutes, check whether the fan module alarm is cleared.

    • If yes, go to 4.

    • If no, go to 3.

  3. Replace the fan module. After 5 minutes, check whether the fan module alarm is cleared.

    For details about how to replace the fan module, see "Replacing Parts" in the server user guide.

    • If yes, go to 4.

    • If no, go to 14.

  4. Check whether the RAID controller card overheating alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 5.

  5. Check whether the temperature room temperature exceeds the normal range.

    • If yes, go to 6.

    • If no, go to 7.

  6. Lower the ambient 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 7.

  7. Check whether the air inlet or outlet is blocked.

    • If yes, go to 8.

    • If no, go to 9.

  8. Clear the blockage. Then, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 9.

  9. Check whether idle disk bays are not installed with hard disk fillers.

    • If yes, go to 10.

    • If no, go to 11.

  10. Install hard disk fillers in idle disk bays. After 5 minutes, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 11.

  11. Check whether air ducts are installed properly.

    • If yes, go to 13.

    • If no, go to 12.

  12. Install air ducts properly. After 5 minutes, check whether the alarm is cleared.

    For details about how to install air ducts, see "Replacing Parts" in the server user guide.

    • If yes, no further action is required.

    • If no, go to 13.

  13. Replace the RAID controller card. Then, check whether the alarm is cleared.

    For details about how to replace the RAID controller card, see "Replacing Parts" in the user guide.

    • If yes, no further action is required.

    • If no, go to 14.
