6.3.2 AD-1C-xx.x Card-Level Indicators
The AD-1C-xx.x card has three card-level LED indicators, described in Table 6-8.
6.3.3 AD-1C-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-1C-xx.x has six LC-PC-II optical ports: two for add/drop channel client
input and output, two for express channel input and output, and two for communication.
6.4 AD-2C-xx.x Card
Note See the “A.8.2 AD-2C-xx.x Card Specifications” section on page A-39 for hardware specifications.
The 2-Channel OADM (AD-2C-xx.x) card passively adds or drops two adjacent 100-GHz channels
within the same band. Sixteen versions of this card—each designed for use with one pair 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. Each version of the
card has a different part number.
The AD-2C-xx.x has the following features:
P3 IN EXP EXP RX
P4 OUT EXP EXP TX
V1 IN COM COM RX
V2 OUT COM COM TX
