on configuration, using a mechanical lift is recommended; for instructions, see "Installing
the M40e 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.
To make the router light enough to install without a mechanical lift, you must remove
most of the components.
WARNING: The procedures in this section apply only to initial installation
and assume that you have not yet connected power to the router. If power
is connected, completely disconnect it before continuing. See Disconnecting
AC Power from the M40e Router or Disconnecting DC Power from the M40e
Router.
Do not stack components on top of one another after removing them from
the chassis. Place each one individually on a flat, stable surface, either on an
antistatic mat or in an electrostatic bag.
Set the removed components far enough away from the installation site that
they will not be in the way as you lift the chassis into the rack.
NOTE: Do not remove the circuit breaker box (on a DC-powered router) or
the Connector Interface Panel (CIP). This topic does not include instructions
for removing these components.
Perform the procedures described in the following sections to remove components from
the chassis, first from the rear and then from the front:
