Use a tape measure to measure the depth of the rack. Measure from the
outside of the front mounting posts to the outside of the rear mounting strip.
The depth must be at least 19.25 inches (48.9 cm) but not greater than
32 inches (81.3 cm).
Measure the space between the inner edges of the left front and right front
mounting posts to ensure that it is 17.75 inches (45.09 cm) wide. (The chassis
is 17.25 inches [43.8 cm] wide and must fit between the mounting posts.)
Remove the rubber feet from the chassis, if needed, to ensure a better fit in
the rack. Place the side of the chassis on a flat surface. Remove the screw that
secures each rubber foot to the chassis.
Place the chassis on the floor or on a sturdy table as close as possible to the
rack. Leave enough clearance so that you can move around the chassis.
Open the rack-mount kit.
