Installing the 0595, 5095, or 7311-D20 expansion unit into a rack

You might need to install an expansion unit into a rack. In addition to information intended to promote safety and reliable operation, illustrations of the related hardware components are also provided and show how these components relate to each other.

1. Slide the cover attachment (G) under the three clips (H) to attach the cover attachment to the cover (F).

2. Using four screws (A), install the rail-mounting guides (B) to the left and right side of the expansion unit chassis.

3. Extend the rails from the rack until they lock into place.
4. Using at least three people, lift the expansion unit onto the rails. The rail guides (B) go over the rails.
5. Align the mounting holes on the chassis with their corresponding holes on the rail.
6. Install the six screws (C) through the rails and secure the screws to the expansion unit chassis.
   
   Figure 3. Installing the expansion unit onto the rails
7. Remove the four screws (A) securing the rail-mounting guides (B) to the expansion unit and remove the rail mounting guides.
   
   Figure 4. Removing the rail-mounting guides
8. Slide the system approximately three-quarters of the way into the rack so that you can access the back of the system from the back of the rack.
9. Attach one end of the cable-management arm to the back of the rack with two screws (D). Attach the other end of the arm to the back of the expansion unit with the two blue press fasteners (E).

10. Go to the front of the rack and extend the rails from the rack until they lock into place.
11. Use two screws (A) to secure the left and right rails in the rack.
    
    Figure 6. Secure the rails
12. Slide the expansion unit into and out of the rack slowly to ensure that the expansion unit can slide freely on the rails. If the expansion unit cannot slide freely on the rails, then slide the expansion unit towards the front of the rack. Then loosen the six screws (C) an eighth of a turn, and then slide the expansion unit into and out of the rack slowly until the expansion unit slides freely on the rails. Slide the expansion unit out toward the front and retighten the six screws (C).
13. Slide the expansion unit completely into the rack.

14. If the system will be transported, install the two securing screws though the front of the expansion unit and into the securing screw mounts.
