4.12.2 OC192 IR/STM64 SH 1550 Card-Level Indicators
4.12.2 OC192 IR/STM64 SH 1550 Card-Level Indicators
Table 4-13 describes the three card-level LED indicators on the OC192 IR/STM64 SH 1550 card.
4.12.3 OC192 IR/STM64 SH 1550 Port-Level Indicators
You can find the status of the OC192 IR/STM64 SH 1550 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.
4.13 OC192 LR/STM64 LH 1550 Card
The OC192 LR/STM64 LH 1550 card provides one long-range SDH STM-64 port per card, compliant
with ITU-T G.707 and G.957, and Telcordia GR-253-CORE (except minimum and maximum transmit
power, and minimum receive power). Also, the port is compliant to ITU-T G.691 (prepublished unedited
version 10/2000) L-64.2, except for optical output power and receiver sensitivity (see Note on page
4-38). The port operates at 9.95328 Gbps over unamplified distances up to 80 km with different types of
fiber such as C-SMF or dispersion compensated fiber limited by loss and/or dispersion. The card
supports concatenated or nonconcatenated payloads on a VC-4 basis, as well as VC-4, VC-3, and VC-12
payloads.
Figure 4-21 shows the OC192 LR/STM64 LH 1550 faceplate and a block diagram of the card.
Figure 4-22 on page 4-37 shows an enlarged view of the faceplate warning.
Note You can differentiate this OC-192/STM-64 card (15454E-L64.2-1) from the OC-192/STM-64 card with
the product ID 15454-OC192LR1550 by looking at the faceplate. This card does not have a laser on/off
switch.
Table 4-13 OC192 IR/STM64 SH 1550 Card-Level Indicators
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.
ACT/STBY LED
Green (Active)
Amber (Standby)
If the ACT/STBY LED is green, the card is operational and ready to carry
traffic. The amber ACT/STBY 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,
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.
