4. Load the switch onto the lift, making sure it rests securely on the lift platform.

5. Using the lift, position the switch in front of the rack, as close as possible to the mounting shelf.

6. Align the switch to the center of the mounting shelf, and lift the switch approximately 0.75 in. (1.9 cm) above the

surface of the mounting shelf.

7. Carefully slide the switch onto the mounting shelf so that the bottom of the switch and the mounting shelf overlap by

approximately 2 in. (5.08 cm).

8. Slide the switch onto the mounting shelf until the mounting brackets or front-mounting flanges contact the rack-rails.

The shelf ensures that the holes in the mounting brackets and the front-mounting flanges of the switch align with the

holes in the rack-rails.

9. Move the lift away from the rack.

10. Install a 10-32, ½-in. screw into each of the open mounting holes aligned with the rack, starting from the bottom.

Ensure that all the mounting screws on one side of the rack are aligned with the mounting screws on the opposite side
and the chassis is level.

11. Tighten the screws.

12. Visually inspect the alignment of the switch. If the switch is installed properly in the rack, all the mounting screws on

one side of the rack are aligned with the mounting screws on the opposite side and the switch is level.

13. Connect the ground wire to the grounding points.

14. Reinstall the switch components. Ensure that all empty slots are covered with a blank panel.
