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 Router or Disconnecting DC Power from the Router.
If you are installing or replacing components in an operational router, see Replacing Hardware Components.
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.
Perform the procedures described in the following sections to remove components from the chassis, first from the rear and then from the front:
