Verifying Rack Dimensions
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 Figure 
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 the distance 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, which is approximately 17.45 in. (44.32 cm) wide, and fits between the mounting posts on the rack.
