Problem solved,
fiber optic in wrong position.
fiber optic in wrong position.
1. Check if the optical connectors are plugged in with correct orientation, we had a customer who plugged them in with the locking clips on the wrong side.
2. Read product bulletin 3BSE084764 about a problem with failing cluster modems and check if your components are in the range of effected serial numbers.
