ALM-0x0149FFFF Above Upper Major Threshold (Inlet Temp)

Description

Alarm message:

Above upper major threshold

This alarm is generated when the sensor detects that the air intake vent temperature is higher than the major alarm upper threshold. This alarm is cleared when the system detects that the temperature is restored to the acceptable range.

Sensor triggering the alarm: Inlet Temp

Attribute

0x0149FFFF

Major

Yes

Impact on the System

The components on the server cannot operate stably.

Possible Causes

  • The ambient temperature exceeds the normal range.

  • The air inlet is blocked.

  • Idle slots or spaces are not installed with filler panels.

  • The component holding the sensor is faulty.

The location of the Inlet Temp sensor varies depending on the server model. For details, see the user guide of the server you use. The XH321 V3 server node is used as an example to describe how to clear the alarm.

The Inlet Temp sensor is located on the left mounting ear of the X6000 chassis. For details, see the X6000 User Guide.

Procedure

  1. Check whether the equipment room temperature exceeds the normal range.

    • If yes, go to 2.

    • If no, go to 3.

  2. Reduce the equipment room temperature to thenormal range. 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 air inlet is blocked.

    • If yes, go to 4.

    • If no, go to 5.

  4. Remove the blockage from the air inlet. Five minutes later, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 5.

  5. Check whether filler panels or baffles are installed in the idle slots or spaces between servers.

    • If yes, go to 7.

    • If no, go to 6.

  6. Install filler panels in idle slots or baffles in spaces between servers. Then, check whether the alarm is cleared.

    • If yes, no further action is required.

    • If no, go to 7.

  7. Replace the component where the air inlet temperature sensor is located. Then, check whether the alarm is cleared.

    • The air inlet temperature sensor of an XH321 V3 server node is on the left mounting ear.
    • The air inlet temperature sensor of an XH310 V3 server node is on the mainboard.
    For details, see the sensor list in the server user guide.

    Take the XH321 V3 as an example, replace the X6000 chassis left mounting ear. For details, see "Replacing Parts" in the user guide.

    • If yes, no further action is required.

    • If no, go to 8.
