Chapter 16 Card Reference
16.7.6 32WSS Card
16.7.6.1 Power Monitoring
Physical photodiodes P1 through P69 monitor the power for the 32WSS card. The returned power level
values are calibrated to the ports as shown in Table 16-48.
16.7.6.2 32WSS Card-Level Indicators
Table 16-49 describes the three card-level LED indicators on the 32WSS card.
16.7.6.3 32WSS Port-Level Indicators
You can find the status of the 32WSS card’s 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 32WSS card has five sets of ports located on the faceplate.
COM RX is the line input, COM TX is the line output, EXP RX is the port where a channel can be added
or passed through, EXP TX is the port that passes through the channels that are not dropped, and
DROP TX is the port for the dropped channels. The xx.x-yy.y TX ports represent the four groups of eight
channels ranging from xx.x wavelength to yy.y wavelength according to the channel plan.

Card-Level Indicators Description
Red FAIL LED 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.
Green ACT LED The green ACT LED indicates that the 32WSS card is carrying traffic or is
traffic-ready.
Amber SF LED 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.
