14.6.4.6 4MD-xx.x Port-Level Indicators
You can find the status of the card ports 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. The 4MD-xx.x card has five sets of ports located on the faceplate. COM RX is
the line input. COM TX is the line output. The 15xx.x TX ports represent demultiplexed channel
outputs 1 to 4. The 15xx.x RX ports represent multiplexed channel inputs 1 to 4.

Description
The red FAIL LED indicates that the card's processor is not ready or that
there is an internal hardware failure. Replace the card if the red FAIL LED
persists.
The green ACT LED indicates that the 4MD-xx.x card is carrying traffic or
is traffic-ready.
The amber SF LED indicates a signal failure on one or more of the card's
ports. The amber SF LED also illuminates when the transmit and receive
fibers are incorrectly connected. When the fibers are properly connected, the
light turns off.
