!HANDLING PRECAUTIONS FOR

STATIC-SENSITIVE DEVICES

This product is designed to protect sensitive components from
damage due to electrostatic discharge (ESD) during normal operation.
When performing installation procedures, however, take proper static
control precautions to prevent damage to equipment. If you are not
sure of the proper static control precautions, contact your nearest
sales or service representative.
To install a DSU and its rear connector plate for the first time:
Procedure
1. At the rear of the carrier, set the tab on the rear connector plate into one of
the slots on the carrier’s backplane (Figure 2). Make sure the rear connector
plate uses the same slot position intended for the DSU.
2. Loosely fasten the screw attached to the rear connector plate, allowing for
slight adjustment that may be needed when installing the DSU.
3. At the front of the carrier, hold the DSU vertically with the latch on its
faceplate in the open position. Then, insert the circuit card into the top and
bottom circuit card guides for the slot that contains the rear connector plate.
