I notice something strange with OSC-CSM card on ONS 15454 MSTP. It showed as red in CTC with APS state is disable. Alarm indicate equipemtn failure. But when I view at card level all ports are green and optical power is good. However on the network and circuit (OCHNC) view one of the line is grey while the other is green and the state is partial. Traffic from the client however is passing through. This is strange. The manual says that I can soft reset the card from CTC or reseat/replace it but I dont want to do this now as this will interrupt operation. What's the best course to take? Apreciate your expert advice. Thanks.
