the card if the red FAIL LED persists.
The green ACT LED indicates that the OC12 IR/STM4 SH 1310 card is
operational and is carrying traffic or is traffic-ready.
The amber SF LED indicates a signal failure or condition such as LOS, LOF,
AIS-L or high BERs on the card's port. The amber SF LED also illuminates
when the transmit and receive fibers are incorrectly connected. When the
fibers are properly connected, the light turns off.
