while two people push on the front-mounting flanges, slide the router onto the
mounting shelves until the mounting brackets or 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 center-mount the chassis, you use the center-mounting brackets attached to
the chassis; if you front-mount the chassis, you use the front-mounting flanges.
If you are installing the router in a four-post rack or cabinet, install a mounting screw
6.
and a cage nut 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.
Loosen the captive screws on the installation handle completely, and remove the
7.
handle from the chassis.
Visually inspect the alignment of the router. If the router is installed properly in the
8.
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.
