Preparing the Equipment Rack
This section explains how to prepare the equipment rack for the 
installation of 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 installation of the AT-SBx3112 
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 
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 40 on page 87. You may use this additional space for other 
network equipment after the chassis is installed.
