Card-Level Indicators Description
Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready or that
there is an internal hardware failure. Replace the card if the red FAIL LED
persists.
Green ACT LED The green ACT LED indicates that the OSC-CSM is carrying traffic or is
traffic-ready.
Amber SF LED The amber SF LED indicates a signal failure or condition such as LOS, LOF,
AIS-L, or high BER on one or more of the card’s ports. The amber SF LED
also illuminates when the transmit and receive fibers are incorrectly
