ALML/4/TEMP_UPPER:The "[STRING1]" temperature of sensor [STRING2](entity) exceeds the upper [STRING3] limit. This problem may be caused by poor ventilation, blocked air filter, fan failure, or idle slots without filler panels installed. (SensorNum=[ULONG], Value=[STRING4], UpperThreshold=[STRING5], LowerThreshold=[STRING6])


The temperature sensor detects that the temperature exceeds the upper limit. This problem may be caused by poor ventilation, blocked air filter, fan failure, or vacant slots without filler panels installed.


Parameter Name Parameter Meaning
[STRING1] Indicates the name of temperature sensor.
[STRING2] Indicates the entity name.
[STRING3] Indicates the alarm severity.
[ULONG] Indicates the number of the temperature sensor.
[STRING4] Indicates the current temperature.
[STRING5] Upper limit of temperature
[STRING6] Indicates the lower limit of temperature.

Possible Causes

  • The hot air in the equipment cannot be exhausted.

  • The air filter is blocked.

  • Vacant slots are not covered by filler panels.

  • The temperature of the environment where the device is located is high.

  • The number of fans on the device is insufficient.

  • A fan on the device is faulty.

  • The temperature of the chip is high.


  1. Clean the air filter and remove the objects that block the air exhaust area (if any). Cover all vacant slots with filler panels to ensure efficient heat dissipation. Then check whether the alarm is cleared.
    • If so, the alarm handling ends.
    • If not, go to step 2.
  2. Check whether the ambient temperature is too high.
    • If so, go to step 3.
    • If not, go to step 4.
  3. Install an external cooling device. Then go to Step 4.
  4. Check whether all fan slots have fans installed.
    • If so, go to step 6.
    • If not, go to step 5.
  5. Install more fans on the device. Then go to Step 6.
  6. Run the display fan command to check whether any fan operates abnormally.
    • If so, go to step 7.
    • If not, go to step 8.
  7. Replace the abnormal fan. Then go to Step 8.
  8. Run the display temperature all command to check whether the card chip overheats.
    • If so, collect log information and configuration information, and then contact technical support personnel.You can collect diagnostic information using the display diagnostic-information command.
    • If not, the alarm handling ends.
