ALML/4/CANBUSNODELOST: Failed to find the CANbus node of [STRING].


A CANbus node is lost.


Parameter Name Parameter Meaning
[STRING] Indicates a slot ID.

Possible Causes

The system scans for CANbus nodes every 30s. If the system does not detect registration of a CANbus node or fails to obtain its software version after 10 detection intervals (5 minutes), the system determines that the CANbus node is lost.


  1. Check whether the log ALML/6/CANBUSNODERESUME is generated.
    • If so, the fault is rectified, and no action is required.
    • If not, go to step 2.
  2. Restart the board where a CANbus node is lost and then check whether this log persists.
    • If so, go to step 3.
    • If not, the alarm handling ends.
  3. Replace this board and check whether this log persists.
    • If so, collect log information and configuration information, and then contact technical support personnel. You can collect diagnostic information using the display diagnostic-information command.
    • If not, the alarm handling ends.
