Parameters

Name Meaning

arg1

Socket number of the CPU, for example, CPUn.

arg2

  • DIMM silkscreen, for example, DIMM020 (A) or DIMM010 (B)
  • CPU socket number and channel number. For example, in a 2488 V5 server, CPU 1 channel 2 indicates the number 2 memory channel of CPU 1, that is, DIMMs DIMM020 and DIMM021.
    NOTE:

    The number of DIMMs corresponding to a memory channel varies depending on the server model.

You can obtain the CPU socket number and channel number corresponding to a DIMM from the server user guide. For example, if you use a 2488 V5 server, see Components > DIMM Slot Locations in the 2488 V5 Server V100R005 User Guide.

arg3

Current reading of the sensor.

arg4

Alarm threshold.

Impact on the System

The overheating affects DCPMM stability and server performance.

Possible Causes

  • The fan module is faulty.
  • The equipment room temperature exceeds the normal range.
  • The air inlet or outlet is blocked.
  • The DCPMM is faulty.

Procedure

  1. Check whether there are fan module alarms.

    • If yes, go to 2.

    • If no, go to 3.

  2. Replace the alarmed fan module. After 5 minutes, 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 air inlet or outlet of the server 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 DCPMM. After the server is powered on, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 8
