OC12 LR/STM4 LH 1310 Card-Level Indicators
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 card is operational and is carrying
traffic or is traffic-ready. The amber ACT LED indicates that the card is part
of an active ring switch (BLSR).
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 is also on if the
transmit and receive fibers are incorrectly connected. If the fibers are
properly connected, the light turns off.
