CAUTION: Lifting the chassis and mounting it in a rack requires four people.
The empty chassis weighs approximately 205 lb (93 kg).
If you are installing the router in an open-frame rack, ensure that the rack is in its
1.
permanent location and is secured to the building. Ensure that the installation site
allows adequate clearance for both airflow and maintenance. For details, see
Clearance Requirements for Airflow and Hardware Maintenance" on page
Attach the installation handle by tightening the captive screws of the handle into the
2.
holes previously occupied by the captive screws of the power supplies (see
Figure 80 on page 193). Tighten the screws, using a Phillips (+) screwdriver, number 2.

Figure 80: Attaching the Installation Handle

Position the router in front of the rack or cabinet, centering it in front of the mounting
3.
shelves. Use a pallet jack if one is available.
CAUTION: Do not lift the router using the installation handle, or the
handles on the sides of the chassis. Use these handles only to help position
the router.
With two people in the front and two people in the back, hold onto the bottom of the
4.
chassis and carefully lift it onto the mounting shelves.
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.
