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.
Slide the router onto the mounting shelves until the mounting brackets or
4.
front-mounting flanges contact the rack rails or spacer bars (depending on your type
of installation). The shelves ensure that the holes in the mounting brackets and the
front-mounting flanges of the chassis align with the holes in the rack rails.
If you are installing the router in a four-post rack or cabinet, install a mounting screw
5.
into each of the holes aligned with the threaded holes in the spacer bars. If you are
installing the router in an open-frame rack, install a mounting screw into each of the
open mounting holes aligned with the rack, starting from the bottom.
Visually inspect the alignment of the router. If the router is installed properly in the
6.
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.
