Chapter 2 Installation

is is an ATX form factor (12” x 9.6”, 30.5 cm x 24.4 cm) motherboard. Before you install

the motherboard, study the conguration of your chassis to ensure that the motherboard

ts into it.

Make sure to unplug the power c ord before installing or re moving the mothe rboard. Failure
to do so may cause physical injurie s to you and d amages to motherboard components.

2.1 Screw Holes

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

Attention! Before installing this moth erboard, be sure to unscrew and remove the stando
at the marked location, under the motherboard, from the chassis, in order to avoid elec tri­cal shor t circuit and damage to your 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.

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 f rom the power supply. Failure to d o so may cau se severe damage to
the motherboard, peripherals, and/or components.
