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 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.
