NOTE: Your system is safety-certified as a free-standing unit and as a component for use in a Dell™ rack cabinet using the customer rack kit. The installation of your system and rack kit in any other rack cabinet has not been approved by any safety agencies.
(continued) CAUTION: Safety Instructions • Use caution when pressing the component rail release latches and sliding a component into or out of a rack; the slide rails can pinch your fingers. • After a component is inserted into the rack, carefully extend the rail into a locking position, and then slide the component into the rack.
Two-Post Rack Installation The two-post rack kit is used to install a system in a two-post, open-frame relay rack, such as those found in telecommunications equipment facilities. Both 3-inch and 6-inch wide two- post racks with universal-hole spacing or wide-hole spacing are accommodated. You can install this kit in a center-mount or a flush-mount configuration.

Universal-Hole Spacing Racks Industry-standard two-post racks with universal-hole spacing have an alternating pattern of three holes per U with center-to-center hole spacing (beginning at the top hole of a 1-U space) of 15.9 mm, 15.9 mm, and 12.7 mm (0.625 inch, 0.625 inch, and 0.5 inch) for the front and back vertical column of holes (see Figure 1-2).
To mark the rack, perform the following steps: Place a mark on the rack’s front vertical rails where you want to locate the bottom of the system you are installing in the two-post rack. The bottom of each 1-U space is at the middle of the narrowest metal area between holes.

Center-Mount Installation The two-post rack kit is shipped with the brackets configured for center-mount installation. To complete the installation, perform the following steps: Locate the right slide assembly and push the back bracket toward the back of the slide assembly (see Figure 1-4). Position the right slide assembly in the two-post rack at the location you marked, push the back bracket forward against the vertical two-post rack, secure the front center- mounting bracket with two 12-24 x 0.5-inch pan-head Phillips screws, and secure the...

Installing the System in the Rack CAUTION: Due to the size and weight of the system, never attempt to install the system by yourself. NOTE: The procedure for installing a system into a rack is identical for flush-mount and center-mount slide assemblies. Pull the slides out to their fully extended position.
