Parameters

Name

Meaning

Alarm Severity

Indicates the alarm severity.

Alarm Source

Indicates the alarm source.

Subject

Indicates the event body for which an alarm is generated.

Time

Indicates the time when an alarm is generated.

Description

Provides an alarm description.

Event Code

Indicates the event code of an alarm.

Impact on the System

The system starts the self-protection mechanism, which may affect system monitoring and maintenance. If the alarm is generated only for the active CMC and the standby CMC is operating properly, an active/standby failover of the CMC will be automatically performed.

System Actions

None

Possible Causes

  • The fan module on a power and fan integrity module (PFM) is faulty.
  • The fan module on a PFM is not detected.
  • The ambient temperature of the equipment room is high.
  • The upper threshold for critical alarms is not properly set for the sensor.

Procedure

  1. Check whether the alarm "ALM-3600002D Front Fan of Counter Rotary Fan 1 Failed" is generated.

  2. Clear the alarm "ALM-3600002D Front Fan of Counter Rotary Fan 1 Failed". Then check whether alarm 17000007 is cleared.

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

  3. Check whether all PFMs are properly installed.

  4. Install PFMs in required slots. Then check whether the alarm is cleared.

    • If yes, no further action is required.
    • If no, go to Step 5.

  5. Check whether the ambient temperature of the equipment room is in a normal range.

    For details about the normal range, see the KunLun 9005 V5 User Guide.

  6. Reduce the ambient temperature of the equipment room by using air conditioners and fans in the equipment room. (For example, lower the temperature of air conditions and increase the fan speed. If air conditions are unavailable, open doors and windows to improve ventilation.) Then check whether the alarm is cleared.

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

  7. Run the smmget [-l smm] -t sensorname -d thresholdall command on the CMC CLI, and check whether the upper threshold for critical alarms is set properly.

    The proper threshold for the sensor is as follows:

    Ambient Temp: 62°C

    If the command output is as follows, the threshold is set properly:

    root@SMM:/# smmget -t Ambient Temp -d thresholdall  
    Upper Non-recoverable: 62.000 Celsius 
    Upper Critical       : 57.000 Celsius 
    Upper Non-critical : 47.000 Celsius 
    Lower Non-critical : Not supported. 
    Lower Critical       : Not supported. 
    Lower Non-critical : Not supported.

  8. Run the smmset -t sensor -d uppernonrecoverable -v value command (value indicates the upper threshold for critical alarms) on the CMC CLI to change the threshold. Then check whether the alarm is cleared.

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

  9. Check whether the fan modules on all PFMs are running properly. If an alarm indicating a low fan speed is generated for the fan module on a PFM, remove and reinstall the PFM. Then check whether the alarm is cleared.

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

  10. Replace the PFM. Then check whether the alarm is cleared.

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

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

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

  12. Check whether the air intake or exhaust vent is blocked. If yes, remove the barriers. 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.

Clearing

This alarm is cleared when the sensor detects that the temperature is lower than the upper threshold for critical alarms.

After the fault is rectified, the system automatically clears the alarm.
