Preparing the Equipment Rack
This section explains how to prepare the equipment rack for the chassis.
The procedure requires the following items:
 #2 Phillips-head screwdriver (not provided)
 Two equipment rack screws (not provided)
To prepare the equipment rack for the AT-SBx8112 Chassis, perform the
following procedure:
Caution
The chassis is heavy and should be mounted as low as possible in
the equipment rack to maximize vertical stability.
1. Reserve 311.1 mm (12.25“) of vertical rack space for the installation of
the AT-SBx8112 Chassis, as shown in Figure 30 on page 92.
2. Do not mount any other equipment within 152.4 mm (6”) above this
space during installation. This additional vertical space is temporary
and allows you enough room to lift and tilt the chassis into its position
in the equipment rack without hitting other equipment, as shown in
Figure 36 on page 99. You may use this additional space for other
network equipment after the chassis is installed.
