Preface

Before using this information and the product it supports, please read the following general infor-

mation.

1. This Service Guide provides you with all technical information relating to the BASIC CON-

FIGURATION decided for GIGABYTE’s “global” product offering. To better t local market-

requirements and enhance product competitiveness, your regional ofce MAY have decided

toextend the functionality of a machine (e.g. add-on card, modem, or extra memory capabil-

ity).These LOCALIZED FEATURES will NOT be covered in this generic service guide. In

suchcases, please contact your regional ofces or the responsible personnel/channel to

provide youwith further technical details.

2. Please note WHEN ORDERING SPARE PARTS, you should check the most up-to-date

informationavailable on your regional web or channel. For whatever reason, if a part num-

ber change is made,it will not be noted in the printed Service Guide. For GIGABYTE-AU-

THORIZED SERVICEPROVIDERS, your GIGABYTE ofce may have a DIFFERENT part

number code to thosegiven in the FRU list of this printed Service Guide. You MUST use the

list provided by yourregional GIGABYTE ofce to order FRU parts for repair and service of

cause harmful interference to radio communications. Operation of thisequipment in a residential area is likely

to cause harmful interference in which case the user will berequired to correct the interference at his own ex-

pense.Properly shielded and grounded cables and connectors must be used in order to meet FCC emission-

limits. Neither the provider nor the manufacturer are responsible for any radio or television interferencecaused

by using other than recommended cables and connectors or by unauthorized changes ormodications to this

equipment. Unauthorized changes or modications could void the user's authority tooperate the equipment.

This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions:

(1) this device may not cause harmful interference, and

(2) this device must accept any interference received, including interference that may cause undesired opera-

tion.

Canadian Department of Communications Compliance Statement

This digital apparatus does not exceed the Class A limits for radio noise emissions from digitalapparatus as

set out in the radio interference regulations of Industry Canada.Le present appareil numerique n'emet pas

de bruits radioelectriques depassant les limites applicables auxappareils numeriques de Classe A prescrites

dans le reglement sur le brouillage radioelectrique edicte parIndustrie Canada.

Class A equipment

This device has been tested and found to comply with the limits for a class A digital device pursuantPart 15 of

the FCC Rules. These limits are designed to provide reasonable protection againstharmful interference when

the equipment is operated in a commercial environment. This equipmentgenerate, uses, and can radiate

interference to radio communication. Operation of thisequipment in a residential area is likely to cause harm-

ful interference, in which case the user will berequired to correct the interference at personal expence.

However, there is no guarantee that interference will not occur in a particular installation. If thisdevice does

cause harmful interference to radio or television reception, which can be determined bytuning the device off

and on, the user is encouraged to try to correct the interference by on or more ofthe following measures:

• Reorient or relocate the receiving antenna

• Increase the separation between the device and receiver

• Connect the device into an outlet on a circuit different from that to which the receiver isconnected'Consult

the dealer or an experienced radio/television technician for help.

1-1 Installation Precautions

The motherboard/system contain numerous delicate electronic circuits and components which

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

read the service guide 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 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

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 certied computer technician.
