You can find the status of the OC192 IR/STM64 SH 1550 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

Note For hardware specifications, see the “A.6.15 OC192 LR/STM64 LH 1550 Card Specifications” section
on page A-41. See Table 4-2 on page 4-5 for optical card compatibility.
Note Any new features that are available as part of this software release are not enabled for this card.
The OC192 LR/STM64 LH 1550 card provides one long-range SONET/SDH OC-192 port compliant
with ITU-T G.707, ITU-T G.691, ITU-T G.957, and Telcordia GR-253-CO RE (except minimum and
maximum transmit power, and minimum receive power). The card port operates at 9.95328 Gbps over
unamplified distances up to 80 km (50 miles) with different types of fiber such as C-SMF or dispersion
compensated fiber limited by loss and/or dispersion. The card supports VT, nonconcatenated (STS-1),
or concatenated payloads.
There are two versions of the OC192 LR/STM64 LH 1550. The earliest version has the product ID
15454-OC192LR1550, and the latest card’s product ID is 15454-OC192-LR2 . These cards have slight
specification differences that are noted throughout this description.
Warning
The laser is on when the optical card is booted. The port does not have to be in service for the laser
to be on.

Table 4-16 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. 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 L ED
Green (Active)
Amber (Standby)
If the ACT/STBY LED is green, the card is operational and re ady 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.
