In a center-mounted position, an optional set of center-mount brackets are secured
to the rack posts and the chassis rack-mounting flanges are then secured to the
center-mount brackets. The center-mounted position moves the center of gravity
of the chassis closer to the vertical axis of the rack posts, which adds to the
security and stability of the rack installation.
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
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.
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 17.25 inches (43.8 cm) wide and fits between the mounting posts on the rack.
