14.7.2.6 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.

14.7.3 AD-4C-xx.x Card

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.
