Verifying Rack Dimensions
Before you begin
Before you install the chassis, measure the space between the vertical mounting flanges (rails) on your
equipment rack to verify that the rack conforms to the measurements shown in the following figure.
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)
Measure for pairs of holes near the bottom, middle, and top of the equipment rack to ensure that the rack posts
are parallel.
Note
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 that is 17.25 inches (43.8 cm) wide and fits between
the mounting posts on the rack.
Attaching Front Rack-Mount Brackets
Before you begin
Before installing the chassis in the rack, you must install the rack-mount brackets on each side of the chassis.
