CAUTION: If you are installing two routers in one rack, install the lower one
first. Installing a router in the 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 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 72 on page 121). Tighten the screws, using a Phillips (+) screwdriver, number 2.

Figure 72: 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.
