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 motherboard to be securely
attached on 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
use with 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
In order to protect the contact pins, please pay
attention to these notices:
1. A maximum 20 cycles of CPU installation
is recommended.
2. Never touch the contact pins with fingers
or any object.
3. Always put on the cap when the CPU is
not in use.
1. Place the board so as to let the lever hook
of the socket is on your left side. Use your left
thumb and forefinger to hold the lever hook,
pull it away from the retention tab.
2. Rotate the lever to fully open position.
3. Use your right thumb on the bottom-right
side of the load plate and lift it up to fully open
position.
4. Use your right thumb and forefinger to
grasp the CPU package. Be sure to grasp on the
edge of the substrate, and face the Pin-1
indicator toward the bottom-left side. Aim at the
socket and place the CPU package vertical
down into the socket.
5. Visually inspect if the CPU is seated well
into the socket. The alignment key must be
located in the notch of package.
6. Use your left hand to hold the load plate,
and use your right thumb to peel the cap off.
