4.8.2 OC48 IR/STM16 SH AS 1310 Card-Level Indicators
The STM-16 port features a 1310-nm laser and contains a transmit and receive connector (labeled) on
the card faceplate. The OC48 IR/STM16 SH AS 1310 card uses SC connectors. The card supports 1+1
unidirectional protection and provisionable bidirectional switching.
The OC48 IR/STM16 SH AS 1310 card detects LOS, LOF, LOP, MS-AIS, and 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.
4.8.2 OC48 IR/STM16 SH AS 1310 Card-Level Indicators
Table 4-9 describes the three card-level LED indicators on the OC48 IR/STM16 SH AS 1310 card.
4.8.3 OC48 IR/STM16 SH AS 1310 Port-Level Indicators
You can find the status of the OC48 IR/STM16 SH AS 1310 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.
4.9 OC48 LR/STM16 LH AS 1550 Card
Note For specifications, see the “A.6.8 OC48 LR/STM16 LH AS 1550 Card Specifications” section on
page A-34.
Note Any new features that are available as part of this software release are not enabled for this card.
The OC48 LR/STM16 LH AS 1550 card provides one long-range, ITU-T G.707- and G.957-compliant,
SDH STM-16 port per card. The interface operates at 2.488 Gbps over a single-mode fiber span. The
card supports concatenated or nonconcatenated payloads at STM-1, STM-4, or STM-16 signal levels on
a per VC-4 basis.

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/Amber ACT LED The green ACT LED indicates that the card is carrying traffic or is
traffic-ready. The amber ACT LED indicates that the card is in standby mode
or is part of an active ring switch (MS-SPRing).
Amber SF LED The amber SF LED indicates a signal failure or condition such as LOS, LOF,
MS-AIS, or high BERs on one or more card 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 link is working, the light turns off.
