4. Using the lift, position the switch in front of the rack or cabinet, centering it in front of the mounting
shelf installed in the rack.
5. Lift the chassis approximately 0.75 in. (1.9 cm) above the surface of the mounting shelf and position
it as close as possible to the shelf.
6. Carefully slide the switch onto the mounting shelf so that the bottom of the chassis and the
mounting shelf overlap by approximately two inches.
Slide the switch onto the mounting shelf until the mounting brackets contact the rack rails. The shelf
ensures that the holes in the mounting brackets of the chassis align with the holes in the rack rails.
7. Move the lift away from the rack.
8. Install a mounting screw into each of the open front-mounting holes aligned with the rack, starting
from the bottom.
9. 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.
