Setup and Operation 2-7
The system has a built-in checking program that automatically tests the components at
power-on. One beep indicates that the system has successfully completed its power-on test.
If there is a problem, a series of beeps may occur. If this happens repeatedly after powering
on the system, power off the system and see Section 4 for troubleshooting.
NOTE:
If the system displays a message
indicating that system settings have changed,
run Setup (see “System Configuration” later in
this section).
If a problem occurs, and is not indicated by beeps, check the following items, then turn to
Section 4 for troubleshooting. Check that:
n
the power switch for the system unit and monitor are on.
n
all cables and power cords are tightly connected.
n
the electrical outlet is working.
n
the monitor's brightness and contrast are adjusted properly.
n
all options are properly installed (see Section 3 for option installation).
SYSTEM CONFIGURATION
This subsection describes the Setup utility program that allows the system configuration
information to be viewed and changed.
NOTE:
The system ships from the factory with
the correct system configuration for each system.
Unless customizing the system or adding an
option, Setup does not need to be run.
System configuration information is stored in nonvolatile memory. Nonvolatile memory in
the system is a complementary metal-oxide semiconductor (CMOS) chip backed up by the
RTC battery chip on the system board. The RTC battery supplies continuous power to the
CMOS memory and maintains configuration information when system power is off.
