The OC12 IR/STM4 SH 1310-4 card provides four intermediate or short range SONET/SDH
OC-12/STM-4 ports compliant with the ITU-T G.707, ITU-T G.957, and Telcordia GR-253-CORE.
Each port operates at 622.08 Mbps over a single-mode fiber span. The card supports VT,
nonconcatenated (STS-1), or concatenated (STS-1, STS-3c, STS-6c, or STS-12c) payloads.

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 ready to carry
traffic. 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.
