4.15.4 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 SDH Troubleshooting Guide
for a complete description of the alarm messages.
4.16 OC192SR1/STM64IO Short Reach and OC192/STM64 Any
Reach Cards
Note For specifications, see the “A.6.15 OC192SR1/STM64IO Short Reach Card Specifications” section on
page A-42.
The OC192SR1/STM64IO Short Reach and OC192/STM64 Any Reach cards (also known in CTC as
STM64-XFP) each provide a single OC-192/STM-64 interface, as follows:
• OC192SR1/STM64IO Short Reach card (SR-1)
• OC192/STM64 Any Reach card (SR-1, IR-2, and LR-2)
The interface operates at 9.952 Gbps over single-mode fiber spans and may be provisioned for both
concatenated and non-concatenated payloads on a per VC-4/STS-1 basis. Specifications references can
be found for the OC-192/STM-64 interface in ITU-T G.691, G.693, and G.959.1 as well as 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 OC192/STM-64 SR-1 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 LR-2
XFP module. The XFP SR, IR, and LR interfaces each provide one bidirectional OC192/STM64
interface compliant with the recommendations defined by ITU-T G6.91.SR-1 is compliant with I-64.1,
IR-2 is compliant with S-64.2b, and LR-2 is compliant with P1L1-2D2.

Card-Level LED Description
Red FAIL LED The red FAIL LED indicates that the card 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 (MS-SPRing).
Amber SF LED The amber SF LED indicates a signal failure or condition such as LOS, LOF,
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.
