Impact on the System


Possible Causes

Cause 1: The active MPU was reset.

Cause 2: The active MPU was reinstalled when the device is running.

Cause 3: The slave switchover command was run.

Cause 4: The active MPU was faulty.


  1. Check whether the original active MPU was reset using the reset slot command or its power is turned off.

    • If so, the alarm handling ends.
    • If not, go to step 2.

  2. Check whether the slave switchover command was executed.

    • If so, the alarm handling ends.
    • If not, go to step 3.

  3. Run the display device command to check whether the original active MPU is installed properly.

    • If so, go to step 5.
    • If not, go to step 4.

  4. Install the original active MPU securely, and then run the display device command to check whether the original active MPU is available.
  5. Check whether the original active MPU is faulty. Perform the active/standby switchover again to check whether the switchover succeeds.

    • If so, the alarm handling ends.
    • If not, collect alarm information and configuration information, and then contact technical support personnel.
