NOTE: One person must be available to lift the switch while another secures it to the rack.
CAUTION: If you are mounting multiple units on a rack, mount the heaviest unit at the
bottom of the rack and mount the other units from the bottom of the rack to the top in
decreasing order of the weight of the units.
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. Position the router in front of the rack or cabinet.
3. Hold onto the bottom of the chassis and carefully lift it so that the mounting brackets contact the
rack rails.
WARNING: To prevent injury, keep your back straight and lift with your legs, not your
back. Avoid twisting your body as you lift. Balance the load evenly and be sure that
your footing is solid.
4. Align the mounting brackets with the holes in the rack rails.
5. Install a mounting screw into each of the open mounting holes aligned with the rack, starting from
the bottom.
