CPU
The VIA EPIA-SN Mini-ITX mainboard can support VIA C7 1.0GHz / 1.8GHz
NanoBGA2 Processor. The VIA processor C7 1.8GHz requires a heatsink with
fan to provide sufficient cooling.

CPU Fan and System Fan: CPUFAN and SYSFAN
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 (positive wire) should be connected to the +12V.
The black wire is Ground and should always be connected to GND .

EMORY MODULE INSTALLATION
Memory Slot: DDR2 DIMM
The VIA EPIA-SN Mini-ITX mainboard provides two 240-DIMM slots for DDR2
667/533 SDRAM memory modules and supports mem ory sizes up to 4GB.
DDR2 SDRAM Module Installation Procedures
• Locate the DIMM slot in the motherboard.
• Unlock a DIMM slot by pressing the r etaining clips outward.
• Align a DIMM on the socket such that the notch on the DIMM
matches the break on the slot.
• Firmly insert the DIMM into the slot until the retaining clips snap
back in place and the DIMM is properly seated.
Available DDR2 SDRAM Configurations
Refer to the table below for available DDR2 SDRAM configurations on the
mainboard.
Slot Module Size Total
DIMM1 64MB, 128MB, 256MB, 512MB, 1GB, 2GB 64MB-2GB
DIMM2 64MB, 128MB, 256MB, 512MB, 1GB, 2GB 64MB-2GB

ONNECTING THE POWER SUPPLY
The VIA EPIA-SN Mini-ITX mainboard supports a conventional ATX power
supply for the power system. Before inser ting the power supply connector,
always make sure that all components are instal led correctly to ensure that
no damage will be caused.
ATX 20-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 plu g firmly
into the connector.

RJ45 LAN Port and USB Connectors
The mainboard provides a standard RJ-45 (10/100
Ethernet PHY and PCIe Gigabit Ethernet) and USB
2.0 ports. These ports allow connection to a Local
Area Network (LAN) through a network hub and USB
2.0 devices.
Audio Port
The Line-Out jack is for connecting to external
speakers or headphones. The Line-In jack is for
connecting to an external audio device such as a CD
player, tape player, etc. The Mic jack is for
connecting to a microphone.
Note:
The audio ports can be switched to Smart 5.1 6-channel au dio output. You
can enable the function by clicking the “Vinyl Audio” icon on your desktop after
installing the audio driver.
After completing the previou s insta llation , con nect the speakers to the 3-jack
connectors on the back panel.
