Installing the Chassis in the Rack Manually

To install the router in the rack (see Figure 69 on page 193):
CAUTION: If you are installing more than one router in a rack, install the lowest one
first. Installing a router in an upper position in a rack or cabinet requires a lift.
CAUTION: Before front mounting the router in a rack, have a qualified technician
verify that the rack is strong enough to support the router's weight and is adequately
supported at the installation site.
CAUTION: Lifting the chassis and mounting it in a rack requires two people. The
empty chassis weighs approximately 52.0 lb (23.6 kg).

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.

Installing the Chassis in the Rack Manually
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. For details, see "Preparing the Site for Router
Installation" on page 29.
Position the router in front of the rack or cabinet, centering it in front of the
mounting shelf. Use a pallet jack if one is available.
With one person on each side, hold onto the bottom of the chassis and carefully
lift it onto the mounting shelf.
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.
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 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.
