Installing the Rear Connector Plate

To install a DSU and its rear connector plate for the first time:

Procedure

1. Configure the DSU to meet the requirements of the application (refer to 

Hardware

Strapping on page 8). Do not disable the front panel switches at this time.

2. At the rear of the carrier, set the tab on the rear connector plate into one of the slots

on the carrier’s backplane. Make sure the rear connector plate uses the same slot
position intended for the DSU.

3. Loosely fasten the screw attached to the rear connector plate, allowing for slight

adjustment that may be needed when installing the DSU.

4. Using a Phillips screwdriver, loosen the screw holding the circuit pack lock that

secures the DSU’s latch, and rotate the lock to the open position. Open the latch.
