4.18.4 15454_MRC-12 Port-Level Indicators

Each port has an Rx indicator. The LED flashes green if the port is receiving a signal, and it flashes red
if the port is not receiving a signal.
You can also find the status of the 15454_MRC-12 card ports by using the LCD screen on the ONS 15454
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 Troubleshooting Guide for
a complete description of the alarm messages.
4.19 OC192SR1/STM64IO Short Reach and OC192/STM64 Any Reach Cards
Note For hardware specifications, see the “A.6.18 OC192SR1/STM64IO Short Reach Card Specifications”
section on page A-42 and the “A.6.19 OC192/STM64 Any Reach Card Specifications” section on
page A-43. See Table 4-2 on page 4-4 for optical card compatibility.
The OC192SR1/STM64IO Short Reach and OC192/STM64 Any Reach cards each provide a single
OC-192/STM-64 interface, as follows:
• OC192SR1/STM64IO Short Reach card (SR-1)
• OC192/STM-64 Any Reach card (SR-1, IR-2, and LR-2)
In CTC, these cards are referred to as “OC192-XFP” cards.
The interface operates at 9.952 Gbps over single-mode fiber spans and can be provisioned for both
concatenated and nonconcatenated payloads on a per STS-1/VC-4 basis. Specification references can be
found for the OC-192/STM-64 interface in ITU-T G.691, ITU-T G.693, and ITU-T G.959.1, and
Telcordia GR-253.
The optical interface uses a 10-Gbps form-factor pluggable (XFP) optical transceiver that plugs into a
receptacle on the front of the card. The OC192SR1/STM64IO Short Reach card is used only with an
SR-1 XFP, while the OC192/STM-64 Any Reach card can be provisioned for use with an SR-1, IR-2, or
Table 4-21 15454_MRC-12 Card-Level Indicators
Card-Level LED Description
Red FAIL LED The red FAIL LED indicates that the card’s processor is not ready. This LED
is on during reset. The FAIL LED 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. If the ACT/STBY LED is amber, the card is operational and in
standby (protect) 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.
