4. Position the chassis in front of the rack, centering it in front of the mounting shelf.
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 chassis onto the mounting shelf so that the bottom of the chassis and the mounting shelf overlap
by approximately 2 in. (5.08 cm).
7. Slide the chassis further until the mounting brackets touch the rack rails. The shelf ensures that the holes in the mounting
brackets and the front-mounting brackets of the chassis align with the holes in the rack rails.
8. Install a mounting 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. Tighten the screws.
9. Reinstall the chassis components. Ensure that all empty slots are covered with a blank panel before operating the
switch.
