Marking the Rack
Determine where you want to place the bottom of the support tray.
1
If you are installing other components in the rack, install the heaviest items at the
bottom of the rack.
Place the 2-U template over the front of the rack rails in the desired location.
2
Position the bottom of the template in line with the desired bottom position of the
3
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.
Mark the upper- and lower-mounting positions on the vertical rails as shown by the
4
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).
