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
components such as a motherboard, CPU or memory. If you do not have an ESD wrist strap,
keep your hands dry and first 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 supply
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 hardware
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 system
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 certified computer technician.
