4.14.2 OC192 LR/STM64 LH ITU 15xx.xx Card-Level Indicators
Table 4-15 describes the three card-level LED indicators on the OC192 LR/STM64 LH ITU 15xx.xx
card.
4.14.3 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 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.
4.15 15454_MRC-12 Multirate Card
Note For specifications, see the “A.6.14 15454_MRC-12 Card Specifications” section on page A-41.
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
“4.17 SFPs and XFPs” section on page 4-40 for more information about SFPs.
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,VC4 payloads, and concatenated payloads at VC4-1c, VC4-2c, VC4-3c, VC4-4c, VC4-8c, or
VC4-16c signal levels. It is fully interoperable with the ONS 15454 SDH G-Series Ethernet cards.
Each 15454_MRC-12 port contains a transmit and receive connector (labeled) on the card faceplate. The
card supports unidirectional and bidirectional facility protection.It also supports both span and ring
switching in MS-SPRing protection scheme. You can provision this card as part of an MS-SPRing,
SNCP, or linear configuration.
Table 4-15 OC192 LR/STM64 LH ITU 15xx.xx Card-Level Indicators
Card-Level LED Description
Red FAIL LED The red FAIL LED indicates that the card 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. If the ACT/STBY LED is amber, the card is in standby 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.
