CAUTION:
verify that the rack is strong enough to support the router's weight and is adequately
supported at the installation site.

1. Ensure that the rack is in its permanent location and is secured to the building. Ensure that the installation
site allows adequate clearance for both airflow and maintenance.
2. Load the router onto the lift, making sure it rests securely on the lift platform.
3. Using the lift, position the router in front of the rack or cabinet, centering it in front of the mounting
shelf.
4. Lift the chassis approximately 0.75 in. above the surface of the mounting shelf and position it as close
as possible to the shelf.
5. Carefully slide the router onto the mounting shelf so that the bottom of the chassis and the mounting
shelf overlap by approximately two inches.
6. Slide the router 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 mounting holes aligned with the rack, starting from the
bottom.
9. Visually inspect the alignment of the router. If the router is installed properly in the rack, all the mounting
screws on one side of the rack should be aligned with the mounting screws on the opposite side and
the router should be level.
