10. Troubleshooting
This section provides useful tips to get the SYS-ITX-N-3900 operating. For
basic hardware installation and configuration, refer to “Installation and
Connections” on page 10. This section addresses system integration issues
in terms of BIOS setting and OS diagnostics.
10.1 BIOS settings
This section assumes that you have correctly selected and connected all
devices with the required cables before applying power. If this is in
question, inspect the connection and application of each of the following
components: 204-pin DDR3 memory, keyboard, mouse, SATA hard disk,
VGA connector, power cable of the device, and all ATX accessories. Failure
of any of these components can cause a system failure.
It is recommended that you press the
DELETE
or
ESC
key and enter the
BIOS setup menu during the initial boot-up sequence to configure a stable
BIOS configuration that can be woken.
10.1.1 Loading the Default Optimal Setting
NOTE If the system appears to be unstable during startup, you can try loading
the default BIOS configuration to see if this solves the issue.
When prompted in the main setup menu, load setup defaults:
1. Apply power to an installed SYS-ITX-N-3900 and press
DELETE
or
ESC
to enter the BIOS setup menu.
2. Select the
Save & Exit
menu and then scroll to
Restore Defaults
.
3. Press
Enter
.
4. To load the default optimal BIOS setup, select
Yes
. This forces the BIOS
settings back to the initial factory configuration.
10.1.2 Reset CMOS BIOS Configuration
You can use jumpers to reset the BIOS CMOS settings to the factory
default. Enable or disable the Clear CMOS Function hardware circuit by
placing or removing the jumper from JP3 as needed. See “CMOS Clear
To reset the BIOS CMOS configuration to the factory default settings:
1. Remove power from the SYS-ITX-N-3900.
2. Find JP3.
3. Remove jumpers from pins 1-2.
4. Install jumpers on pins 2-3 and wait five seconds.
