4.2.2 OC3 IR 4/STM1 SH 1310 Card-Level Indicators
Table 4-3 describes the three card-level LED indicators on the OC3 IR 4/STM1 SH 1310 card.
4.2.3 OC3 IR 4/STM1 SH 1310 Port-Level Indicators
Eight bicolor LEDs show the status per port. The LEDs shows green if the port is available to carry
traffic, is provisioned as in-service, and is part of a protection group, in the active mode. You can find
the status of the four card ports using the LCD screen on the ONS 15454 SDH 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 SDH Troubleshooting Guide for a complete
description of the alarm messages.
4.3 OC3 IR/STM1 SH 1310-8 Card
The OC3 IR/STM1 SH 1310-8 card provides eight intermediate or short range SDH STM-1 ports
compliant with ITU-T G.707, and ITU-T G.957. Each port operates at 155.52 Mbps over a single-mode
fiber span. The card supports VC-4 and nonconcatenated or concatenated payloads at the STM-1 signal
level. Figure 4-3 shows the card faceplate.

Card-Level LED Description
Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready. The FAIL
LED is on during reset and 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,
MS-AIS, 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.
