If you are installing other components in the rack, install the heaviest items at the bottom of the rack. 2 Place the 2-U template over the front of the rack rails in the desired location. 3 Position the bottom of the template in line with the desired bottom position of the system chassis. NOTE: If your rack has wide hole spacing, go to step 5. If your rack has universal-hole spacing, continue with the next step. 4 Mark the upper- and lower-mounting positions on the vertical rails as shown by the bottom and top V-notches on the sides of the template. Each 1-U (1.75-inch) vertical space on a rack with universal-hole spacing has three holes with center-to-center spacing between holes (beginning at the top of a 1-U space) of 0.625, 0.625, and 0.5 inches (see Figure 1-2).
