Installing the Router without aMechanical Lift
You can install the router into a rack either with or without the he lp of a mechanical
lift. B ecause 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, youmust remove components from the chassis
to reduce its weight before lifting it into the rack. The reduced chassis weight is
approximately 115lb (52 kg), so installing it safely still requires three people to lift
and another person to insertthe mounting screws.
Table22 lists th e weight of the chassis and major components.
