1-1 Installation Precautions

The motherboard contains numerous delicate electronic circuits and components which can

become damaged as a result of electrostatic discharge (ESD). Prior to installation, carefully read

the user's manual and follow these procedures:

• Prior to installation, do not remove or break motherboard S/N (Serial Number) sticker or

warranty sticker provided by your dealer. These stickers are required for warranty validation.

• Always remove the AC power by unplugging the power cord from the power outlet before

installing or removing the motherboard or other hardware components.

• When connecting hardware components to the internal connectors on the motherboard,

make sure they are connected tightly and securely.

• When handling the motherboard, avoid touching any metal leads or connectors.

• It is best to wear an electrostatic discharge (ESD) wrist strap when handling electronic com-

ponents such as a motherboard, CPU or memory. If you do not have an ESD wrist strap,

keep your hands dry and rst touch a metal object to eliminate static electricity.

•

Prior to installing the motherboard, please have it on top of an antistatic pad or within an

electrostatic shielding container.

• Before unplugging the power supply cable from the motherboard, make sure the power sup-

ply has been turned off.

• Before turning on the power, make sure the power supply voltage has been set according to

the local voltage standard.

• Before using the product, please verify that all cables and power connectors of your hard-

ware components are connected.

• To prevent damage to the motherboard, do not allow screws to come in contact with the

motherboard circuit or its components.

• Make sure there are no leftover screws or metal components placed on the motherboard or

within the computer casing.

• Do not place the computer system on an uneven surface

• Do not place the computer system in a high-temperature environment.

• Turning on the computer power during the installation process can lead to damage to sys-

tem components as well as physical harm to the user.

• If you are uncertain about any installation steps or have a problem related to the use of the

product, please consult a certied computer technician.
