Hello, friend!
When the MA5616 service board (PON board) is abnormal, perform the following steps to locate the fault:
Check whether the service board is added offline.
Check whether the type of the inserted service board is the same as that configured in the system.
Check whether the power supply for the service board is normal.
Check whether the service board is inserted properly.
Check whether the board is faulty.
To facilitate fault report, save the results of the following steps.
Take ESD measures before removing and inserting a board.
Procedure
1. Check whether the service board is added offline.
If the board is added offline and is not inserted actually, no need to proceed.
If the board is not added offline, go to 2.
2. Run the display board frameid/slotid command to query the type of the faulty board, check the type of the actual board inserted into the slot, and then check whether their types are the same or compatible.
If their types are the same or compatible, go to 4.
If their types are different or not compatible, check whether the system configurations are correct. If it is confirmed that system configurations are correct, insert a board of the correct type as configured in the system into the slot. Then, go to 3.
If their types are different or not compatible, check whether the system configurations are correct. If it is confirmed that system configurations are incorrect, run the board delete frameid/slotid command to delete the original configurations, after the system displays a message indicating that the board is automatically found, run the board confirm frameid/slotid command to confirm the board. Then, go to 3.
3. Wait for five minutes and then check whether the service board is working properly.
If the board is working properly, go to 10.
If the fault persists, go to 4.
4. Run the display broad-service power-off state command to check whether the function of powering off the broadband services is in the On state.
If the function is in the On state, go to 5.
If the function is not in the On state, go to 6.
When the function of powering off the broadband services is in the On state, the device powered by batteries automatically cuts off the power supply for the broadband services to extend the narrowband service time.
5. Check whether the MA5616 is currently powered by batteries.
If the MA5616 is powered by batteries, go to 10.
If the MA5616 is not powered by batteries, go to 6.
6. Check whether the board is firmly inserted.
If the board is firmly inserted, go to 8.
If the board is not firmly inserted, remove and insert the board, and ensure that the board is firmly inserted. Then, go to 7.
If the board is not properly installed, component detection fails during board startup and therefore the startup fails. The fault can be rectified only by removing and inserting the board.
7. Check whether the fault is rectified.
If the fault is rectified, go to 10.
If the fault persists, go to 8.
8. Replace the original board, wait for about five minutes, and then check whether the new board is in the normal state.
A board is in the Auto_find state after being discovered automatically. After the board confirm frameid/slotid command is executed to confirm the board status, the board is in the normal state.
If the new board is in the normal state, the original board is faulty. Go to 10.
If the fault persists, go to 9.
9. Contacting Huawei for Assistance.
10. End.
Thanks!
