3. Install the rack bar on the front posts just below the desired height of the bottom of the chassis. The

rack bar requires 1 RU below the chassis.

Use the rack bar as a guide to mount the chassis. It is not required to support the weight of the

chassis; you can remove it when the chassis is securely mounted in the rack. To install the rack bar,

first insert two cage nuts (item 2 in Figure 6) into each post at the desired height.

Hold the rack bar (item 1 in Figure 6) so that the smooth side faces outward and the arrows point

upward. Align the holes in the rack bar with the cage nuts in the posts. Attach the bar to the front-

rack posts using the mounting screws and washers shipped with the rack bar (items 3 and 4 in Figure

6). Tighten each screw to secure the rack bar to the posts.

NOTE: The installation procedure in this section describes how to install the C9010 in a 4-post

rack using the rack bar provided in the base configuration package. For information about how

to use Dell ReadyRails or a rack mount tray to install the C9010, follow the instructions in

Installing Dell ReadyRails or Installing a Rack Mount Tray. Then continue with Step 4.
