Installing the Router without a Mechanical Lift

You can install the router into a rack either with or without the help of a mechanical lift. Because the router weighs between 190 lb (86 kg) and about 370.5 lb

(168 kg) depending on configuration, using a mechanical lift is recommended; for instructions, see “Installing the Router Using a Mechanical Lift” on page 81.

If you do not use a mechanical lift, you must remove components from the chassis to reduce its weight before lifting it into the rack. The reduced chassis weight is approximately 115 lb (52 kg), so installing it safely still requires three people to lift and another person to insert the mounting screws.

Table 22 lists the weight of the chassis and major components.
