Install the Router Using a Mechanical Lift
Using a mechanical lift to maneuver the router into the rack is recommended because of the
router’s size and weight. The lift must be able to accommodate the router’s
weight—approximately 280 lb (127 kg) fully configured—and must fit between the support
posts of the rack.

First, perform the following prerequisite procedures:
Place the rack in its permanent location, allowing adequate clearance for airflow

Then, perform the following procedures to install the router:
1.
If you are installing the router in the upper half of the rack, install the C-bracket first (see
“Rack-Mounting Brackets” on page 94). Follow this procedure:
“Rack-Mounting Brackets” on page 94). Follow this procedure:
a.
Select the height in the rack at which to mount the C-bracket. The M40 router is
35 in. (89 cm or 20 U) high, so if you are mounting two routers in the rack
leave at least that much distance between the C-bracket shelf and both the top
and bottom cross-pieces of the rack.

b.
As you stand in front of the rack, position the C-bracket so that the shelf is
protruding toward you, and align the C-bracket mounting holes with holes in
the rack rails. If you are front mounting the router, install the C-bracket into the
rack from the rear. Make sure the mounting holes on both sides are parallel.
