16.6.2 32DMX-O Card
16.6.1.2 Power Monitoring
Physical photodiodes P1 through P32 monitor the power for the 32MUX-O card. The returned power
level values are calibrated to the ports as shown in Table 16-27.
16.6.1.3 32MUX-O Card-Level Indicators
The 32MUX-O card has three card-level LED indicators, described in Table 16-28.
16.6.1.4 32MUX-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 32MUX-O card has five sets of ports located on the faceplate.
COM Tx is the line output. MON is the optical monitoring port. The xx.x-yy.y RX ports represent the
four groups of eight channels ranging from xx.x wavelength to yy.y wavelength according to the channel
plan.
16.6.2 32DMX-O Card
The 32-Channel Demultiplexer (32DMX-O) card demultiplexes 32 100-GHz-spaced channels identified
in the channel plan. The 32DMX-O takes up two slots in an ONS 15454 and can be installed in
Slots 1 to 5 and 12 to 16.
The 32DMX-O features include:
• AWG that enables channel demultiplexing functions.
• Each single-channel port is equipped with VOAs for automatic optical power regulation after
demultiplexing. In the case of electrical power failure, the VOA is set to its maximum attenuation
for safety purposes. A manual VOA setting is also available.

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 32MUX-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.
