Hello, friend!

Check whether the two alarms affect services.

If the alarms affect services, perform the following operations:

According to previous experience, the NS4 board reported the OTU4_LOF alarm, which may be caused by the fluctuation of the module clock.

Solution

1. The board is reset.

2. Upgrading the module software version can effectively reduce the fault rate.

Thanks!
