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 44 mm (1.75 inches) above the original mark you made (or count up
three holes in a rack with universal-hole spacing) (see Figure 1-13).
Each 1 U (44 mm, or 1.75 inches) of 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 inch (see Figure 1-13).
NOTE:
If your rack has universal-hole spacing, you have completed the procedure
for marking the rack.
3
Place a mark 44 mm (1.75 inches) above the original mark you made (or count up to
the next hole in the rack with wide-hole spacing (see Figure 1-14).
Each 1 U (44 mm, or 1.75 inches) of vertical space on a rack with wide-hole spacing
has two holes with center-to-center spacing between holes (beginning at the top of a
1-U space) of 31.7 mm (1.25 inches) (see Figure 1-14).
Installing the Slide Assemblies in the Rack
You can install the slide assemblies in a two-post, open-frame rack having either universal-
hole spacing (see Figure 1-13) or wide hole spacing (see Figure 1-14). You can install the
1-U slide assemblies in either a flush-mount or center-mount configuration.
