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

Memory Slot: DDR2 DIMM
The VIA NAS 7800 mainboard provide one 240-DIMM slots for DDR2
667/533/400 SDRAM memory modules and supports memory sizes up
to 1GB.
DDR2 SDRAM Module Installation Procedures
• Locate the DIMM slot in the motherboard.
• Unlock a DIMM slot by pressing the retaining 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.

Connecting the Power Supply
The VIA NAS 7800 mainboard supports a conventional ATX 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.
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
plug firmly into the connector.
