Chapter 16 Card Reference
16.6.3 32DMX Card
16.6.2.2 32DMX-O Card-Level Indicators
The 32DMX-O card has three card-level LED indicators, described in Table 16-30 .
16.6.2.3 32DMX-O 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 32DMX-O card has five sets of ports located on the faceplate. MON is the
output monitor port. COM RX is the line input. 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.
16.6.3 32DMX Card
The 32-Channel Demultiplexer card (32DMX) is a single-slot optical demultiplexer. The card receives
an aggregate optical signal on its COM RX port and demultiplexes it into to 32 100-GHz-spaced
channels. The 32DMX card can be installed in Slots 1 to 6 and in Slots 12 to 17.
The 32DMX includes these high-level features:
•
COM RX port: COM RX is the input port for the aggregate optical signal being demultiplexed. This
port is supported by both a VOA for optical power regulation and a photodiode for optical power
monitoring.
• DROP ports (1 to 32): On its output, the 32DMX provides 32 drop ports that are typically used for
dropping channels within the ROADM node. Each drop port has a photodiode for optical power
monitoring. Unlike the two-slot 32DMX-O demultiplexer, the drop ports on the 32DMX do not have
a VOA per channel for optical power regulation.
•
A terminal site can be configured using only a 32WSS card and a 32DMX card plugged into the east
or west side of the shelf.
Figure 16-30 shows the 32DMX card front panel and the basic traffic flow through the ports.
Table 16-30 32DMX-O Card-Level Indicators
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 32DMX-O 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.
