7.7.7 40-DMX-C Port-Level Indicators
You can find the alarm status of the 40-DMX-C card ports using the LCD screen on the ONS 15454
fan-tray assembly. The screen displays the number and severity of alarms on a given port or slot. For the
procedure to view these counts, refer to "Manage Alarms" in the Cisco ONS 15454 DWDM Procedure
Guide.

Cards" section on page
The single-slot 40-Channel Demultiplexer C-band, even channels (40-DMX-CE) card demultiplexes 40
100-GHz-spaced even-numbered channels identified in the channel plan
sends them to dedicated output ports. The overall optical power can be adjusted using a single VOA that
is common to all channels. The 40-DMX-CE card is unidirectional, optically passive, and can be
installed in Slots 1 to 6 and 12 to 17.
7.8.1 40-DMX-CE Card Faceplate Ports
The 40-DMX-CE card has two types of ports:

Description
The red FAIL LED indicates that the card's processor is not ready or that an
internal hardware failure occurred. Replace the card if the red FAIL LED
persists.
The green ACT LED indicates that the 40-DMX-C 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 turns on when the transmit and receive fibers
are incorrectly connected. When the fibers are properly connected, the light
turns off.

COM RX port: COM RX is the line input port for the aggregate optical signal being demultiplexed.
This port is supported by a VOA for optical power regulation and a photodiode for per-channel
optical power monitoring.
Note By default, the VOA is set to its maximum attenuation for safety purposes (for example,
electrical power failure). A manual VOA setting is also available.
