2: Mainboard Installation
Install the Mainboard
Install the mainboard in a system chassis (case). The board is a
Micro ATX size mainboard with a twin-tier of I/O ports. You can
install this mainboard in any ATX case. Ensure that your case has
an I/O cover plate that matches the ports on this mainboard.
Install the mainboard in a case. Follow the instructions provided by
the case manufacturer using the hardware and internal mounting
points on the chassis.
Connect the power connector from the power supply to the
ATX1
connector on the mainboard.
If there is a cooling fan installed in the system chassis, connect the
cable from the cooling fan to the
CHSFAN
fan power connector
on the mainboard.
Connect the cable from the PC speaker to the
SPK1
header on the
mainboard.
Connect the case switches and indicator LEDs to the
SW1
header.
If there are a headphone jack or/and a microphone jack on the front
panel, connect the cables to the
AUDIO1
header on the mainboard.
See the illustrations below for the guide to the SW1 and AUDIO1
