4.19.3 MRC-2.5G-4 Card-Level Indicators
Table 4-23 shows the 15454_MRC-4 port availability and line rate for each port, based on total available
bandwidth. To use the table, go to the rows for the bandwidth that you have available, as determined in
Table 4-22. Each row indicates what line rate can be provisioned for each port (identified in the MCR-4
Port Number row). The Ports Used column shows the total number of ports that can be used with each
bandwidth scheme.
With the MRC-4 card, you can have a maximum of 16 combinations of STS-48 available bandwidths with the OC-12 and OC-3
port rates.
4.19.3 MRC-2.5G-4 Card-Level Indicators
Table 4-21 describes the three card-level LEDs on the MRC-2.5G-4 card.
4.19.4 MRC-2.5G-4 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 MRC-2.5G-4 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.

Table 4-24 MRC-2.5G-4 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.
