CAUTION: Safety Instructions Use the following safety guidelines to help ensure your own personal safety and to help protect your system and working environment from potential damage. For complete safety information, see the System Information Guide. Rack Mounting of Systems Observe the following precautions for rack stability and safety. Systems are considered to be components in a rack. Thus, "component" refers to any system as well as to various peripherals or supporting hardware.
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m CAUTION: Safety Instructions (continued) • 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. • Do not overload the AC supply branch circuit that provides power to 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 twopost 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. The two-post kit incorporates slide assemblies that enable the system to be pulled out of the rack for servicing.

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).

w w w. d e l l . c o m | s u p p o r t . d e l l . c o m To mark the rack, perform the following steps: 1 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. NOTE: If your rack has wide-hole spacing, go to step 3. 2 Place a mark 88 mm (3.
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: 1 Locate the right slide assembly and push the back bracket toward the back of the slide assembly (see Figure 1-4). 2 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 centermounting bracket with two 12-24 x 0.

Flush-Mount Installation The two-post rack kit is shipped with the brackets configured for center-mount installation. To prepare the slide assemblies for flush-mount installation in the two-post rack, perform the following steps: 1 Locate the two slide assemblies and place them, side by side, on a smooth work surface, with the front ends of the slide assemblies toward you. Position both slide assemblies so that the center brackets are facing upward (see Figure 1-5).

w w w. d e l l . c o m | s u p p o r t . d e l l . c o m 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. 1 Pull the slides out to their fully extended position. CAUTION: Because of the size and weight of the system, never attempt to install the system in the slide assemblies by yourself.
3 Push the tab on the front end of the cable-management arm into a mating latch on the inner segment of the slide assembly (see Figure 1-7). The latch clicks when locked. Figure 1-7.

Figure 1-9. Routing the Power Cords power receptacle housing power cord plug CAUTION: Allow some slack in each cable as you route them around hinges in the cable-management arm. Routing Cables 1 Attach the I/O cable connectors to their respective connectors on the system back panel. For details on cable connections, see your system’s Installation and Troubleshooting Guide and the User’s Guide.
w w w. d e l l . c o m | s u p p o r t . d e l l . c o m NOTE: As you pull the system out to its furthest extension, the slide assemblies will lock in the extended position. To push the system back into the rack, press the slide release latch on the side of the slide, and then slide the system completely into the rack. 4 Slide the system in and out of the rack to verify that the cables are routed correctly and do not bind, stretch, or pinch with the movement of the cable-management arm.
