SmartAX MA5818 fault

Hi, friend!

Can you provide the display xdsl vectoring state command output?

Hi, sir!

MA5818(diagnose)%%display xdsl vectoring state

Hi, friend

According to your feedback, the VD board is not synchronized with the VP board.

Vectoring out-of-synchronization check process:

1. Switch the faulty board to another slot and check whether vectoring can be synchronized. Check whether the fault is related to the slot.

2. If the synchronization still fails, insert the same board and check whether the synchronization is successful. Check whether the fault is related to the VDSL board.

3. Query the status of the VP board. Remove the VP board and check whether the backplane connector is damaged. If the backplane connector is not damaged, insert the backplane connector and check whether the fault is rectified.

4. If the fault persists, replace the VP board. Check whether the fault is related to the VP board.

5. If the fault persists, replace the lower frame. Check whether the fault is related to the subrack.

Thanks!
