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.)
