Warning
The laser is on when the optical card is booted. The port does not have to be in service for the laser
to be on.
Figure 4-2 shows the card faceplate and block diagram.

You can install the OC3 IR/STM1 SH 1310-8 card in Slots 1 to 4 and 14 to 17. The card can be
provisioned as part of a path protection or in an ADM configuration. Each interface features a 1310-nm
laser and contains a transmit and receive connector (labeled) on the card faceplate. The card uses LC
connectors on the faceplate that are angled downward 12.5 degrees.
The OC3 IR/STM1 SH 1310-8 card supports 1+1 unidirectional and bidirectional protection switching.
You can provision protection on a per port basis.
The OC3 IR/STM1 SH 1310-8 card detects LOS, LOF, LOP, AIS-L, and RDI-L conditions. Refer to the
Cisco ONS 15454 Troubleshooting Guide for a description of these conditions. The card also counts
section and line BIP errors.
To enable APS, the OC3 IR/STM1 SH 1310-8 card extracts the K1 and K2 bytes from the SONET
overhead to perform appropriate protection switches. The OC3 IR/STM1 SH 1310-8 card supports full
DCC/GCC connectivity for remote network management.
