Tip To allow space to attach the cable-management brackets to the chassis in the rack easily, make certain that you use the
rack-mount bracket ear holes specified in Step 9.
Step 8 Hold the chassis in position against the mounting rails and follow these steps:
a. Insert the bottom screw into the second ear hole from the bottom of the rack-mount ear and use a hand-held screwdriver
to tighten the screw to the rack rail.
b. Insert the top screw into the second bracket hole from the top of the rack-mount bracket ear hole diagonally from the
bottom screw and tighten the screw to the rack rail. See Figure 3.
c. Repeat these steps for the other side of the chassis.
Note As a result of using the specified rack-mount bracket ear holes, the cable-management bracket can be easily
attached to the rack-mount bracket after the chassis is in the rack.
This completes the procedure for installing the chassis in a four-post rack. Proceed to the “Attach the Cable-Management
Bracket” section on page 8 to continue the installation.
Two-Post Rack Installation
Note Make certain that you attach the cable-management bracket to the chassis after you install the chassis in an equipment
rack.
Note Inner clearance (the width between the inner sides of the two posts or rails) must be at least 19 inches (48.26 cm).
Airflow through the chassis is from front to back.
