1.3 Choosing a Computer Chassis
• Choose a chassis big enough to install this motherboard.
•
As some features for this motherboard are implemented by cabling connectors on the
motherboard to indicators and switches or buttons on the chassis, make sure your chassis
supports all the features required.
• If there is a possibility of adopting some more hard drives, make sure your chassis has
sufficient power and space for them.
• Most chassis have alternatives for I/O shield located at the rear panel. Make sure the I/O
shield of the chassis matches the I/O port configuration of this motherboard. You can find
an I/O shield specifically designed for this motherboard in its package.
1.4 Installing Motherboard
Most computer chassis have a base with many
mounting holes to allow the motherboard to be
securely attached, and at the same time, prevent
the system from short circuits. There are two
ways to attach the motherboard to the chassis
base: (1) with studs, or (2) with spacers.
Basically, the best way to attach the board is
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.
※
Always power off the computer and unplug the AC power cord before adding or
removing any peripheral or component. Failing to so may cause severe damage
to your motherboard and/or peripherals. Plug in the AC power cord only after
you have carefully checked everything.
To install this motherboard:
1. Locate all the screw holes on the
motherboard and the chassis base.
2. Place all the studs or spacers needed on
the chassis base and have them tightened.
3. Face the motherboard’s I/O ports toward
the chassis’s rear panel.
4. Line up all the motherboard’s screw holes
with those studs or spacers on the chassis.
5. Install the motherboard with screws and
have them tightened.
※
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.
Face the chassis’s rear panel.
