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.

describes the three card-level LEDs on the MRC-2.5G-4 card.
MRC-2.5G-4 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.
