4.17.2 OC192 LR/STM64 LH ITU 15xx.xx Port-Level Indicators
You can find the status of the OC192 LR/STM64 LH ITU 15xx.xx 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.
4.18 15454_MRC-12 Multirate Card
For hardware specifications, see the
Note
page
The 15454_MRC-12 multirate card provides up to twelve OC-3/STM-1 ports, twelve OC-12/STM-4
ports, or four OC-48/STM-16 ports using small form-factor pluggables (SFPs), in any combination of
line rates. All ports are Telcordia GR-253 compliant. The SFP optics can use SR, IR, LR, coarse
wavelength division multiplexing (CWDM), and DWDM SFPs to support unrepeated spans. See the
"4.21 Optical Card SFPs and XFPs" section on page 4-52
The ports operate at up to 2488.320 Mbps over a single-mode fiber. The 15454_MRC-12 card has twelve
physical connector adapters with two fibers per connector adapter (Tx and Rx). The card supports VT
payloads, STS-1 payloads, and concatenated payloads at STS-3c, STS-6c, STS-9c, STS-12c, STS-18c,
STS-24c, STS-36c, or STS-48c signal levels. It is fully interoperable with the ONS 15454 G-Series
Ethernet cards.
The 15454_MRC-12 port contains a transmit and receive connector (labeled) on the card faceplate. The
card supports 1+1 unidirectional and bidirectional facility protection. It also supports 1+1 protection in
four-fiber BLSR applications where both span switching and ring switching might occur. You can
provision this card as part of an BLSR, path protection, or 1+1 linear configuration.
Longer distances are possible in an amplified system using dispersion compensation.

OC192 LR/STM64 LH ITU 15xx.xx Card-Level Indicators
Description
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.
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).
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.
