ALM-0x0C0AFFFF Memory Overtemperature Major Alarm (DIMMN/CPUM Memory)

Description

Alarm message:

Critical overtemperature

This alarm is generated when a sensor detects that the DIMM temperature is higher than the major alarm threshold.

This alarm is generated by the following sensors:

  • DIMMN
  • CPUM Memory

Attribute

Alarm ID

Alarm Severity

Auto Clear

0x0C0AFFFF

Major

Yes

Parameters

Name

Meaning

N

DIMM silkscreen

M

Slot number of the CPU.

Impact on the System

Overheating affects memory and server performance.

Possible Causes

  • A fan module is faulty.
  • The fan module is not installed.
  • The equipment room temperature exceeds the normal range.
  • The air inlet or outlet is blocked.
  • Idle slots or spaces are not installed with filler panels.
  • The air duct is not installed.
  • The mainboard is faulty.
  • The DIMM is faulty.

Procedure

  1. Check whether the fan fault alarm is generated.

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

  2. Clear the fan fault alarm. Then check whether the alarm is cleared.

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

  3. Check whether all fans are properly installed.

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

  4. Install fans in spare slots properly. Then check whether the alarm is cleared.

    For details about how to install the fans, see the E9000 Server User Guide.
    • If yes, no further action is required.
    • If no, go to 5.

  5. Check whether the ambient temperature is higher than 40°C (104°F).

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

  6. 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) Then check whether the alarm is cleared.

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

  7. Check whether the air intake vent or air exhaust vent is blocked.

    • If yes, go to 8.
    • If no, go to 9.

  8. Remove the barriers. Then check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 9.

  9. Check whether the filler panels are inserted into the idle slots or spaces of the chassis.

    • If yes, go to 11.
    • If no, go to 10.

  10. Insert a filler pane into each vacant slot. Then check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 11.

  11. Power off the node and remove it from the chassis. Then check whether the air duct is properly installed in the server..

    • If yes, go to 13.
    • If no, go to 12.

  12. Install the air duct properly, and insert the node into the chassis to power it on. Then, check whether the alarm is cleared.

    For details, see the server user guide.
    • If yes, no further action is required.
    • If no, go to 13.

  13. Switch the DIMMs connected to the alarmed CPU to a CPU that is working normall. Then, check whether the alarm is generated for the new CPU.

    For details about the DIMM layout, see the server user guide or use the Huawei Server Product Memory Configuration Assistant.
    • If yes, go to 14.
    • If no, go to 15.

  14. Replace the DIMMs of the alarmed CPU. Then, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 15.

  15. Replace the mainboard. Then check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to 16.

  16. On the HMM WebUI, choose System Management > Information Collection, and collect logs.
  17. Contact Huawei technical support.
