Installing the Chassis Installation Brackets
Figure 1: Verifying Equipment Rack Dimensions
Step 1
Mark and measure the distance between two holes on the left and right mounting rails.
The distance should measure 18.31 inches ± 0.06 inches (46.5 cm ± 0.15 cm).
Note Measure for pairs of holes near the bottom, middle, and top of the equipment rack to ensure that the rack posts
are parallel.
Step 2 Measure the space between the inner edges of the left front and right front mounting flanges on the equipment rack.
The space must be at least 17.7 inches (45 cm) to accommodate the chassis.
Installing the Chassis Installation Brackets
Each chassis is shipped with two chassis installation brackets in the accessory kit. These brackets aid in
installing a chassis into a 19-inch rack. These brackets are used as a support base to vertically position and
set the chassis before installing the rack mount screws.
Step 1 Determine the position in the rack where you want to mount the chassis.
If you are mounting more than one chassis in the rack, start from the bottom or the center of the rack. Hold the chassis
installation bracket, where the bottom of the chassis will be positioned vertically in the rack.
Step 2
Secure the chassis installation bracket to the front rails with rack-mount screws.
If a second internal rack rail is present which is not more than 23 inches from the front rail, position the second installation
bracket to create a rear support for the chassis during installation.
