Installing optional devices
There are many servers and optional devices that you can install in the rack cabinet. Always read the
documentation that comes with your server or optional device for detailed installation instructions.
When you install devices in the rack cabinet, secure each device or the rails for that device on rack-mounting
flanges. Some devices come with threaded holes on the rail-mounting flanges. Other devices require that
you use clip nuts to install them in the rack cabinet.
Always install the heaviest devices in the bottom of the rack cabinet.
For information about optional, compatible devices that you can install in the rack cabinet, go to the
ServerProven website at

Installing clip nuts
You must use clip nuts for all optional devices that do not have threaded holes. Install clip nuts on the rack-
mounting flanges as shown in Figure 9 “Installing clip nuts on the rack-mounting flanges” on page 12.
Note: The rack cabinet comes with a supply of clip nuts, and devices that require them come with clip nuts.
