• The equipment has been exposed to moisture
• The equipment has not work well or you cannot get it work according to User's
Manual.
• The equipment has dropped and damaged
• If the equipment has obvious sign of breakage
12. DO NOT LEAVE THIS EQUIPMENT IN AN ENVIRONMENT UNCONDITIONED,
STORAGE TEMPERATURE ABOVE 60 C (140F), IT MAY DAMAGE THE
EQUIPMENT.
CAUTION: Explosion or serious damage may occur if the battery is
incorrectly replaced. Replace only with the same or equivalent
battery type recommended by the manufacturer.

Specifications
The ultra-compact and highly integrated VIA EPIA-NX Nano-ITX
mainboard is the smallest form-factor available today. Through a
high level of integration, the Nano-ITX measures at only 50% of
the size of a Mini-ITX mainboard. The mainboard enables the
creation of an exciting new generation of small, ergonomic,
innovative and affordable embedded systems.

Installation
This chapter provides you with information about hardware
installation procedures. It is recommended to use a grounded wrist
strap before handling computer components. Electrostatic discharge
(ESD) can damage some components.

CPU
The VIA EPIA-NX Nano-ITX mainboard can support VIA C7 NanoBGA2 and
VIA Eden NanoBGA2 processors. The processor requires a heatsink with fan
for 1.5GHz SKU and a fanless heatsink for 1.2GHz SKU.
CPU Fan and System Fan: CPU_FAN and SYS_FAN
The CPU_FAN (CPU fan) and SYS_FAN (system fan) run on +12V and
maintain system cooling. When connecting the wire to the connectors,
always be aware that the red wire (positive wire) should be connected to
+12V. The black wire is Ground and should always be connected to GND.

MEMORY MODULE INSTALLATION
Memory Slot: DDR2_SODIMM
The VIA EPIA-NX Nano-ITX mainboard provides one SODIMM slot for DDR2
533 SDRAM memory modules and supports memory sizes up to 1GB.
Insert the SODIMM module at a 45 degree angle.
Push the SODIMM module back towards the board until the clips lock the
module in place.
Available DDR2 SDRAM Configurations
Refer to the table below for available DDR2 SDRAM configurations on the
mainboard.

CONNECTING THE POWER SUPPLY
The VIA EPIA-NX Nano-ITX mainboard supports a Nano-ITX power supply for
the power system. Before inserting the power supply connector, always
make sure that all components are installed correctly to ensure that no
damage will be caused.
Nano-ITX 12-Pin Power Connector
To connect the power supply, make sure the power plug is inserted in the
proper orientation and the pins are aligned. Then push down the plug firmly
into the connector.

Power Switch (PW_BN)
Connect to a 2-pin power button switch. Pressing this button will turn the
system power on or off.
Reset Switch (RST_SW)
The reset switch is used to reboot the system rather than turning the power
ON/OFF. Avoid rebooting the system, if the HDD is still working. Connect
the reset switch from the system case to this pin.
Power LED (PWR_LED)
The LED will light when the system is on. If the system is in S1 (POS - Power
On Suspend) or S3 (STR - Suspend To RAM) state, the LED will blink.
HDD LED (HD_LED)
HDD LED shows the activity of a hard disk drive. Avoid turning the power off
when the HDD LED still has a lit. Connect the HDD LED from the system case
to this pin.
Speaker (SPEAK)
The speaker from the system case is connected to this pin.
