radiate radio frequency energy and, if not installed and used in accordance with

the instruction manual, may cause harmful interference to radio communications.

However, there is no guarantee that interference will not occur in a particular

installation. If this equipment does cause harmful interference to radio or televi-

sion reception, which can be determined by turning the equipment off and on,

the user is encouraged to try to correct the interference by one or more of the

following measures:

• Reorientorrelocatethereceivingantenna.

• Increasetheseparationbetweentheequipmentandthereceiver.

• Connecttheequipmentintoanoutletonacircuitdifferentfromthattowhich

the receiver is connected.

• ConsultthedealeroranexperiencedradioTVtechnicianforhelp.

Notice:

1. The changes or modifications not expressly approved by the party responsible

for compliance could void the user’s authority to operate the equipment.

Introduction

Static Electricity Precautions

It is quite easy to inadvertently damage your PC, system board, components

or devices even before installing them in your system unit. Static electrical dis-

charge can damage computer components without causing any signs of physical

damage. You must take extra care in handling them to ensure against electro-

static build-up.

1. To prevent electrostatic build-up, leave the system board in its anti-static bag

until you are ready to install it.

2. Wear an antistatic wrist strap.

3. Do all preparation work on a static-free surface.

4. Hold the device only by its edges. Be careful not to touch any of the compo-

nents, contacts or connections.

5. Avoid touching the pins or contacts on all modules and connectors. Hold

modules or connectors by their ends.

Important:

Electrostatic discharge (ESD) can damage your processor, disk drive and

other components. Perform the upgrade instruction procedures described

at an ESD workstation only. If such a station is not available, you can

provide some ESD protection by wearing an antistatic wrist strap and

attaching it to a metal part of the system chassis. If a wrist strap is

unavailable, establish and maintain contact with the system chassis

throughout any procedures requiring ESD protection.

Safety Measures

To avoid damage to the system:

• UsethecorrectACinputvoltagerange.

To reduce the risk of electric shock:

• Unplug the power cord before removing the system chassis cover for instal-

lation or servicing. After installation or servicing, cover the system chassis

before plugging the power cord.

Introduction

Features

Watchdog Timer

The Watchdog Timer function allows your application to regularly “clear” the sys-

tem at the set time interval. If the system hangs or fails to function, it will reset

at the set time interval so that your system will continue to operate.

DDR3

DDR3 delivers increased system bandwidth and improved performance. The ad-

vantages of DDR3 are its higher bandwidth and its increase in performance at a

lower power than DDR2.

Graphics

The integrated Intel

®

HD graphics engine delivers an excellent blend of graphics

performance and features to meet business needs. It provides excellent video

and 3D graphics with outstanding graphics responsiveness. These enhancements

deliver the performance and compatibility needed for today’s and tomorrow’s

businessapplications.SupportsLVDSandVGAdisplayoutputs.

Serial ATA

Serial ATA is a storage interface that is compliant with SATA 1.0a specification.

With speed of up to 3Gb/s (SATA 2.0), it improves hard drive performance faster

than the standard parallel ATA whose data transfer rate is 100MB/s. The band-

width of the SATA 3.0 will be limited by carrier board design.

Gigabit LAN

The Intel 82567V Gigabit Ethernet Phy controller supports up to 1Gbps data

transmission.

Hardware Installation

Important:

When the Standby Power LED lit red, it indicates that there is power on

the board. Power-off the PC then unplug the power cord prior to install-

ing any devices. Failure to do so will cause severe damage to the board

and components.

System Memory

Important:

Electrostatic discharge (ESD) can damage your board, processor, disk

drives, add-in boards, and other components. Perform installation proce-

dures at an ESD workstation only. If such a station is not available, you

can provide some ESD protection by wearing an antistatic wrist strap

and attaching it to a metal part of the system chassis. If a wrist strap

is unavailable, establish and maintain contact with the system chassis

throughout any procedures requiring ESD protection.

DDR3 SODIMM

The system board is equipped with one 204-pin SODIMM socket that support

DDR3 memory modules.

Hardware Installation

Installing the DIM Module

Note:

The system board used in the following illustrations may not resemble

the actual one. These illustrations are for reference only.

1. Make sure the PC and all other peripheral devices connected to it has been

powered down.

2. Disconnect all power cords and cables.

3. Locate the SODIMM socket on the system board.

4. Note the key on the socket. The key ensures the module can be plugged into

the socket in only one direction.

Hardware Installation

6. Push down the module until the clips at each end of the socket lock into

position. You will hear a distinctive “click”, indicating the module is correctly

locked into position.

Clip

5. Grasping the module by its edges, align the module into the socket at an ap-

proximately 30 degrees angle. Apply rm even pressure to each end of the

module until it slips down into the socket. The contact ngers on the edge of

the module will almost completely disappear inside the socket.

Jumper Settings

Clear CMOS Data

If you encounter the following,

a) CMOS data becomes corrupted.

b) You forgot the supervisor or user password.

you can recongure the system with the default values stored in the ROM BIOS.

To load the default values stored in the ROM BIOS, please follow the steps below.

1. Power-off the system and unplug the power cord.

2. Set pins 2 and 3 to On. Wait for a few seconds and set the jumper back to

its default setting, pins 1 and 2 On.

3. Now plug the power cord and power-on the system.

Connect the CPU fan’s cable connector to the CPU fan connector on the board.

The cooling fan will provide adequate airow throughout the chassis to prevent

overheating the CPU and board components.
