Setting Up the System 2-9
Installing the Slide Rail Assemblies into the Rack Cabinet
Before you can mount the server in the rack cabinet, you must install the slide
rail assemblies in the rack cabinet.
Note:
You must use the following procedure to prepare
the rack cabinet before mounting the server into it. Observe
all safety precautions, warnings, and cautions noted
throughout this chapter.
1. Determine where you want to install the server in the rack cabinet.
!
To improve rack stability, mount the server towards the bottom of the
rack cabinet.
!
If there are units already installed, install the server into the next empty
space from the bottom of the rack cabinet.
2.
Starting at the bottom of the rack cabinet or at the top or bottom of a
previously mounted unit, measure the number of screw hole locations on the
front vertical mounting rails and rear vertical mounting rails for the slide rail
assemblies. Mark the location with a pencil on the outside of both the front
and rear vertical mounting rails.
Note:
For vertical reference, every three screw holes on
the rack vertical mounting rail are equal to 1U (1.75 inches).
3. Measure the distance between the front and rear vertical mounting rails of
your system rack. See Figure 2-5. You’ll use this measurement for a
preliminary adjustment of the slide rails in the next step.
