Hardware Setup 2-1
Chapter 2. Hardware Setup
Before the Installation: Turn off the power supply switch (fully turn off the +5V standby power), or
disconnect the power cord before installing or unplugging any connectors or add-on cards. Failing to do
so may cause the motherboard components or add-on cards to malfunction or damaged.
2-1. Install The Motherboard
Most computer chassis have a base with many mounting holes to allow a motherboard to be securely
attached and at the same time, prevented from short circuits. There are two ways to attach the
motherboard to the chassis base:
1. use with studs
2. or use with spacers
In principle, the best way to attach the board is to
studs. Only if you are unable to do this should
you attach the board with spacers. Line up the
holes on the board with the mounting holes on the
chassis. If the holes line up and there are screw
holes, you can attach the board with studs. If the
holes line up and there are only slots, you can
only attach with spacers. Take the tip of the
spacers and insert them into the slots. After doing
this to all the slots, you can slide the board into
position aligned with slots. After the board has been positioned, check to make sure everything is OK
before putting the chassis back on.
ATTENTION: To prevent shorting the PCB circuit, please REMOVE the metal studs or spacers if they
are already fastened on the chassis base and are without mounting-holes on the motherboard to align with.

2-2. Install CPU, Heatsink and Fan Assembly
Please pay attention to the following notices
before installing the CPU and heatsink/fan
assembly.
1. Always use the processor with the
Heatsink and Fan Assembly installed.
2. Do not touch the pins on the processor.
3. If you ever need to reinstall the Heatsink
and fan Assembly, please clean the
heatsink surface and apply new thermal
interface material first.
1. Pull out the socket locking lever slightly,
then lift it up.
2. Align the corner with triangle mark of the
processor with the marking on the motherboard,
and then place the processor vertical down into
the socket.
3. Lower the locking lever to the fully locked
position.
4. Apply thermal interface material.
5. Place the heatsink and fan assembly onto
the retention frame. Match the heatsink clip
with the socket mounting lug. Hook the spring
clip to the mounting lug.
