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 following figure.
Figure 20: Verifying Equipment Rack Dimensions
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).
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 the 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.
Determine where in the rack you want the chassis to be mounted. If you are mounting more than one chassis
in the rack, then start from the bottom up or the center of the rack. The following figure shows the brackets
attached to the chassis. Depending on the bracket holes you use, the chassis may protrude in the rack.
