6.4.4 AD-2C-xx.x Port-Level Indicators
You can find the status of the card port 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 AD-2C-xx.x card has eight LC-PC-II optical ports: four for add/drop channel
client input and output, two for express channel input and output, and two for communication.
6.5 AD-4C-xx.x Card
See the
Note
The 4-Channel OADM (AD-4C-xx.x) card passively adds or drops all four 100-GHz-spaced channels
within the same band. Eight versions of this card—each designed for use with one band of
wavelengths—are used in the ONS 15454 DWDM system. The card bidirectionally adds and drops in
two different sections on the same card to manage signal flow in both directions. There are eight versions
of this card with eight part numbers.
The AD-4C-xx.x has the following features:

AD-2C-xx.x Card-Level Indicators
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 AD-2C-xx.x card is carrying traffic
or is traffic-ready.
The amber SF LED indicates a signal failure. 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.

Passive cascade of interferential filters perform the channel add and drop functions.
Four software-controlled VOAs in the add section, one for each add port, regulate the optical power
of inserted channels.
Two software-controlled VOAs regulate insertion loss on express and drop path, respectively.
Internal control of the VOA settings and functions, photodiode detection, and alarm thresholds.
Software-monitored virtual photodiodes (firmware calculation of port optical power) at the common
DWDM output and input ports.
