E120 and E320 11.1.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. To maintain
airflow requirements, a plenum must be installed above the E320 router before any
piece of equipment (other than an E320 router) is installed above the router. If you
choose not to install a plenum, be sure to include 2 U of space between the E320
router and the other component for proper exhaust. A plenum, however, is highly
recommended.

installed
With one person standing on the left side of the router and another standing on

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

If the router was delivered with the modules already installed, see "Cabling the
Router" on page 47, for instructions on connecting cables.
