4.5.2 OC12 LR/STM4 LH 1310 Port-Level Indicators
4.5.2 OC12 LR/STM4 LH 1310 Port-Level Indicators
You can find the status of the OC12 LR/STM4 LH 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.
4.6 OC12 LR/STM4 LH 1550 Card
The OC12 LR/STM4 LH 1550 card provides one long-range, ITU-T G.707- and G.957-compliant, SDH
STM-4 port per card. The interface operates at 622.08 Mbps over a single-mode fiber span. The card
supports concatenated or nonconcatenated payloads on a per VC-4 basis. Figure 4-8 shows the OC12
LR/STM4 LH 1550 faceplate.
Green/Amber ACT LED The green ACT LED indicates that the card is operational and 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 (BLSR).
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 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 link is working, the
light turns off.
