Installing the Router without a
Mechanical Lift
You can install the router into a r ack either with or without the h elp 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 r educe 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.
