If you intend to install more than one PowerEdge 8450 system in the rack, you
must install the slide assemblies so that 7 units (U) (12.25 inches) of vertical
space is between the top of one slide assembly and the top of the next. In the
Dell rack, the rails of the rack are marked by small indentations in 1-U (1.75-inch)
increments (see Figure 1-6).

2. To install the slide assemblies in the rack, perform the following steps:
NOTE: When installing the slide assemblies, be sure that the black rubber stops
at the ends of the channels are at the back of the rack.
a. Use the installation template to mark the locations of the slide assembly
mounting-bracket tabs and cage nuts.
b. Slide the back mounting bracket towards the center of the slide assembly to
slightly reduce the slide assembly's overall length (see Figure 1-7).
