ALM-0149FFFF/0149FF01 Above Upper Major Threshold (LSW Temp)

Description

Alarm message:

Above upper major threshold

This alarm is generated when the sensor detects that the temperature of the LSW is higher than the upper threshold for major alarms. This alarm is cleared when the sensor detects that the temperature of the indicator board is lower than the upper threshold.

This alarm is generated by the following sensor:

  • LSW Temp

Parameters

Name

Meaning

Time

Indicates the time when an alarm is generated.

Sensor

Name of the sensor that generated the alarm.

Event

Provides detailed information about the alarm.

Severity

Indicates the severity of the alarm.

Event Code

Indicates the event code of an alarm.

Impact on the System

Overtemperature of the LSW causes the switching chip of the switch module to lose packets or generate incorrect packets, affecting services.

Possible Causes

  • A fan module is faulty.
  • The service volume is massive.
  • The ambient temperature is higher than 30°C (86°F).
  • The air intake vent is blocked.
  • The air exhaust vent is blocked.
  • The heat sink is in poor contact with the CPU.
  • The switch module is faulty.

Procedure

  1. Check whether a low fan speed alarm is generated for a fan module.

    Log in to the MM910 CLI command-line interface (CLI) or WebUI, and check for fan module alarms.

  2. Remove and then reinstall the fan module. 5 minutes later, check whether the fan module alarm is cleared.

  3. Replace the fan module. 5 minutes later, check whether the fan module alarm is cleared.

    For details about how to replace a fan module, see the server user guide.

  4. Check whether the services running on the server are in a massive volume.

  5. Stop non-critical services to reduce the service workloads on the server. Then check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 6.

  6. Check whether the ambient temperature is higher than 30°C (86°F).

  7. Lower the ambient temperature to a range of 10°C to 30°C (50°F to 86°F). Five minutes later, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 8.

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

  9. Remove barriers from the air intake or exhaust vent. Then check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 10.

  10. Power off the server, open the chassis, and check whether the heat sink is in poor contact with the CPU.

  11. Remove and reinstall the heat sink, and power on the server. Five minutes later, check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 12.

  12. Replace the switch module, then check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 13.

  13. Contact Huawei technical support for help.
