Dear friend!
The NO_BD_PARA is an alarm indicating that the board parameters are not set. This alarm occurs when the system cannot detect the parameter file of the board, which is when the system cannot detect the optical module parameters.
Configuration reference:

If the parameters are correctly configured, perform the following steps to troubleshoot the fault:
1. View the NO_BD_PARA alarm on the NCE to confirm the relevant board.
2. Perform a cold reset on the board. Then, check whether the NO_BD_PARA alarm is cleared.
If the services travel through the board are not configured with protection, the services are interrupted after the cold reset of the board.
3. If the alarm persists, replace the faulty board.
Thank you!
