2-8 Setting Up the System
Getting Familiar with the System
Before setting up your system, you should become familiar with the system’s
features, such as the location of your system's front and rear panel switches,
indicators and connectors, etc. Note that this section describes the tower-based
system controls (switches and indicators) and connectors, which are identical for
the rack-mount system.
