Juniper Networks M160 manual Installing the Router without a Mechanical Lift

Installing the Router without a Mechanical Lift

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 Power from the Router” on page 200.

If you are installing or replacing components in an operational router, see “Replacing Hardware Components” on page 139.

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:
