4.3.1 OC3 IR/STM1 SH 1310-8 Card-Level Indicators
Table 4-4 describes the three card-level LEDs on the eight-port OC3 IR/STM1 SH 1310-8 card.
4.3.2 OC3 IR/STM1 SH 1310-8 Port-Level Indicators
Eight bicolor LEDs show the status per port. The LEDs show green if the port is available to carry traffic,
is provisioned as in-service, is part of a protection group, or is in the active mode. You can also find the
status of the eight card ports by using the LCD screen on the ONS 15454 fan-tray assembly. Use the LCD
to view the status of any port or card slot; the screen displays the number and severity of alarms for a
given port or slot. Refer to the Cisco ONS 15454 Troubleshooting Guide for a complete description of
the alarm messages.
4.4 OC12 IR/STM4 SH 1310 Card
Note For hardware specifications, see the “A.6.3 OC12 IR/STM4 SH 1310 Card Specifications” section on
page A-27. See Table 4-2 on page 4-4 for optical card compatibility.
The OC12 IR/STM4 SH 1310 card provides one intermediate or short range SONET OC-12 port
compliant with ITU-T G.707, ITU-T G.957, and Telcordia GR-253-CORE. The port operates at
622.08 Mbps over a single-mode fiber span. The card supports VT, nonconcatenated (STS-1), or
concatenated (STS-3c, STS-6c, or STS-12c) payloads. Figure 4-3 shows the OC12 IR/STM4 SH 1310
faceplate and a block diagram of the card.
Note The OC12 IR 1310 and OC12/STM4 SH 1310 cards are functionally the same.
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.

Card-Level LED Description
Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready. This LED
is on during reset. The FAIL LED flashes during the boot process. Replace
the card if the red FAIL LED persists.
Green ACT LED The green ACT LED indicates that the card is carrying traffic or is
traffic-ready.
Amber SF LED 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
is also on if the transmit and receive fibers are incorrectly connected. If the
fibers are properly connected and the links are working, the light turns off.
