Juniper Networks 8 manual Preparing the Equipment Racks, Installing the Router

ERX 8.0.x Hardware Guide

Preparing the Equipment Racks

Following your installation plan, use a tape measure and marking pen to measure and mark space on each equipment rack for each router component. For horizontal spacing, follow Network Equipment Building System (NEBS) requirements. If you choose not to install a plenum, be sure to include 2 U of space between each chassis for proper exhaust. A plenum, however, is highly recommended.

Installing the Router

To complete the installation of the router in a rack, you need:

A Phillips screwdriver

Depending on the router, up to eight 10-32 x 3/8 Phillips screws (provided with the router) for each router to be installed

WARNING: Three people are required to install the router in a rack: two to lift the system into position and one to screw it to the rack.

CAUTION: Make sure all persons handling a router wear an antistatic device.

To install the router in the rack:

1.With one person standing on the left side of the router and another standing on the right side, lift the router into the rack.

2.Position the router in its designated location in the equipment rack. Make sure the holes of the mounting brackets align evenly with the holes of the equipment rack on both sides.

3.Starting at the bottom, have the third person secure the router in the equipment rack by using the 10-32 x 3/8 Phillips screws.

4.Connect the necessary cables. (See “Cabling ERX Routers” on page 53 for instructions on installing the cables.)
