Chapter 2 Installation

This is a mini ITX form factor (6.7'' x 6.7'', 17.02 cm x 17.02 cm) motherboard. Before

you install the motherboard, study the conguration of your chassis to ensure that the

motherboard ts into it.

2.1 Screw Holes

Place screws into the holes indicated by circles to secure the motherboard to the chassis.

Do not over-tighten the screws! Doing so may damage the motherboard.

2.2 Pre-installation Precautions

Take note of the following precautions before you install motherboard components or

change any motherboard settings.

1. Unplug the power cord from the wall socket before touching any components.

2. To avoid damaging the motherboard’s components due to static electricity, NEVER

place your motherboard directly on the carpet or the like. Also remember to use a

grounded wrist strap or touch a safety grounded object before you handle the compo-

nents.

3. Hold components by the edges and do not touch the ICs.

4. Whenever you uninstall any component, place it on a grounded anti-static pad or in

the bag that comes with the component.

5. When placing screws into the screw holes to secure the motherboard to the chassis,

please do not over-tighten the screws! Doing so may damage the motherboard.

Before you install or remove any component, ensure that the power is switched o or the

power cord is detached from the power supply. Failure to do so may cause severe damage to

the motherboard, peripherals, and/or components.

Make sure to unplug the power cord before installing or removing the motherboard. Failure

to do so may cause physical injuries to you and damages to motherboard components.
