Installation
This chapter provides you with information about hardware setup
procedures. While installing the mainboard, carefully hold the
components and closely follow the installation procedures. Some
components may be damaged if they are installed incorrectly.
It is recommended to use a grounded wrist strap before handling
computer components. Static electricity can damage some
components.

CPU
The VIA EPIA-PD Mini-ITX Mainboard includes an embedded VIA Eden
Processor or VIA C3 E-Series Processor. The CPUFAN (CPU fan) and SYSFAN
(system fan) run on +12V and maintain system cooling. When connecting the
wire to the connectors, always be aware that the red wire is the Positive and
should be connected to the +12V. The black wire is Ground and should be
connected to GND. The CPU, System and Power fan connectors have sensors
to detect fan speed.
The VIA C3 E-Series Processor
With low power consumption and advanced
thermal dissipation properties, the embedded
VIA C3 E-Series requires only a small fan to
guarantee performance and reliability. Ensure
that the CPU Fan Connector is correctly installed
as shown.
8
The VIA Eden Processor
Providing ultra-low power consumption and
advanced thermal dissipation properties, the
VIA Eden Processor features a fanless design.
The VIA Eden Processor requires only a
heatsink as shown.
Caution:
This motherboard is not designed to support overclocking. Any attempt to
operate beyond product specifications is not recommended. We do not
guarantee the damages or risks caused by operation beyond product
specifications.

DDR Module Installation Procedures
1. Push the white retaining latches at either end of the DIMM slot outwards.
2. Align the DDR module with the corresponding notches on the DIMM slot.
The modules will only fit if placed in the correct position.
3. With both hands, press the DDR module down into the DIMM slot so that
the white retaining latches rotate up and secure the module in place
(see picture below).

ONNECTING THE POWER SUPPLY
The VIA EPIA-PD Mini-ITX Mainboard requires an ATX power supply to be
connected. Before inserting the power supply connector, always make sure
that all components are installed correctly to ensure that no damage will be
caused.
ATX 20-Pin Power Connector
To connect the ATX power supply, make sure the plugs of the power supply
are inserted in the proper orientation and the pins are correctly aligned. Then,
push down the power supply plug firmly into the connector.
