4.3.1 OC3 IR/STM1 SH 1310-8 Card-Level Indicators
You can install the OC3IR/STM1 SH 1310-8 card in Slots 1 to 4 and 14 to 17. The card can be
provisioned as part of an SNCP 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, angled downward 12.5 degrees.
The OC3IR/STM1 SH 1310-8 card supports 1+1 unidirectional and bidirectional protection switching.
You can provision protection on a per port basis.
The OC3IR/STM1 SH 1310-8 card detects loss of signal (LOS), loss of frame (LOF), loss of pointer
(LOP), multiplex section alarm indicator signal (MS-AIS), and multiplex section far-end receive failure
(MS-FERF) conditions. Refer to the Cisco ONS 15454 SDH Troubleshooting Guide for a description of
these conditions. The card also counts section and line BIP errors.
To enable an MS-SPRing, the OC3 IR/STM1 SH 1310-8 card extracts the K1 and K2 bytes from the SDH
overhead to perform appropriate protection switches. The OC3IR/STM1 SH 1310-8 card supports full
GCC connectivity for remote network management.
4.3.1 OC3 IR/STM1 SH 1310-8 Card-Level Indicators
Table 4-4 describes the three card-level LED indicators for the OC3IR/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 shows green if the port is available to carry
traffic, is provisioned as in-service, is part of a protection group, or in the active mode. You can also find
the status of the eight 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.
4.4 OC12 IR/STM4 SH 1310 Card
Note For specifications, see the “A.6.3 OC12 IR/STM4 SH 1310 Card Specifications” section on page A-30.
Table 4-4 OC3IR/STM1 SH 1310-8 Card-Level Indicators
Card-Level LED Description
Red FAIL LED The red FAIL LED indicates that the card 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 card ports. The amber signal fail (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.
