Unpacking and Installing the Chassis

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 the figure below.
Procedure
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
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.
