ALML/4/HSB_SWITCH_CAUSE

Message

ALML/4/HSB_SWITCH_CAUSE:[STRING1] causes MPU board[ULONG] to reset. Switch cause code: [STRING2].

This log records reset information of the master switch.

Parameter Name	Parameter Meaning
[STRING1]	Cause description of active/standby switchover. The specific causes are as follows: Unknown switch reason: unknown reason. VRP command force: forced reset through command line. Master MPU is no memory: The master switch has insufficient memory. VRP find task deadloop: task infinite loop. Batch was not over: task abnormal. Master switch to slave Interrupt: Active/standby switchover results in reset of the switch. Ecm Channel was faulty: ECM channel failure. Monitor bus communication Interrupt: CANbus communication interrupted MPU board was pulled out: The switch is removed.
[ULONG]	Slot ID of the active switch
[STRING2]	Cause code of active/standby switchover. 0: unknown reason. 1: forced reset through command line. 2: The master switch has insufficient memory. 3: task infinite loop 4: task abnormal 5: Active/Standby switchover causes the master switch to reset. 6: ECM channel failure. 7: CANbus communication interrupted 8: The switch is removed.

Reason 1:

Forced reset is performed through the command line.

Reason 2:

The master switch has insufficient memory.

Reason 3:

Task infinite loop occurs.

Reason 4:

A task is abnormal.

Reason 5:

Active/Standby switchover causes the master switch to reset.

Reason 6:

An ECM channel fails.

Reason 7:

The communication of the CANbus is interrupted.

Reason 8:

The switch is removed.

Check whether the master switch is reset for routing maintenance.
- If so, the alarm handling ends.
- If not, go to step 2.
