If you cannot use a mechanical lift to install the T640 router (the preferred method), you
can install it manually. Before installing the router manually, you must first remove most
components from the chassis, and you must reinstall the components after the router
is installed in the rack. With components removed, the chassis weighs approximately
205 lb (93 kg).
This procedure to remove components from the chassis is for initial installation only, and
assumes that you have not connected power cables or cords to the router. The procedure
describes how to remove components from the chassis, first from the rear and then from
the front:
