Description
The red FAIL LED indicates that the card's processor is not ready. Replace
the card if the red FAIL LED persists.
The green ACT LED indicates that the OC3 IR 4/STM1 SH 1310 card 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 BER on one or more of the card's ports. 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.
