ALM-0x0147FFFF Above Upper Minor Threshold (BioInlet R Temp)

Description

Alarm message:

Above upper minor threshold

This alarm is generated when the temperature sensor detects thatthe air intake temperature of the rear I/O board is higher than the minor alarm upper threshold. This alarm is cleared when the system detects that the temperature is restored to the acceptable range.

This alarm applies only to the RH8100 V3 only.

Sensor triggering the alarm: BioInlet R Temp

Yes

Impact on the System

The components on the server cannot operate stably.

If this alarm persists, the system temperature further increases, which will trigger another alarm of a higher severity. To avoid problem escalation, clear the high-temperature alarm as soon as possible.

Possible Causes

  • The ambient temperature exceeds the normal range.

  • The air inlet is blocked.

  • Idle PCIe slots in rear I/O chassis are not installed with filler panels.

  • The rear I/O board 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 12.

  4. Check whether the rear I/O board high temperature 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 the idle PCIe slots exist in rear I/O chassis.

    • 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. Replace the rear I/O board, then check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 12.

  12. Contact Huawei technical support.
