About this Manual

This manual can be downloaded from the website.

The manual is subject to change and update without notice, and may be based on editions

that do not resemble your actual products. Please visit our website or contact our sales

representatives for the latest editions.

Warranty

1. Warranty does not cover damages or failures that arise from misuse of the product,

inability to use the product, unauthorized replacement or alteration of components and

product specifications.

2. The warranty is void if the product has been subjected to physical abuse, improper

installation, modification, accidents or unauthorized repair of the product.

3. Unless otherwise instructed in this user’s manual, the user may not, under any

circumstances, attempt to perform service, adjustments or repairs on the product,

whether in or out of warranty. It must be returned to the purchase point, factory or

authorized service agency for all such work.

4. We will not be liable for any indirect, special, incidental or consequential damages to

the product that has been modified or altered.

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 discharge can damage computer

components without causing any signs of physical damage. You must take extra care in

handling them to ensure against electrostatic 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 components,

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 installation or servicing. After installation or servicing, cover

the system chassis before plugging the power cord.

INTRODUCTION

XFeatures

Watchdog Timer

The Watchdog Timer function allows your application to regularly “clear” the system 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.

DDR4

DDR4 delivers increased system bandwidth and improves performance. The advantages of

DDR4 provide an extended battery life and improve the performance at a lower power than

DDR3/DDR2.

Graphics

The integrated GC7000 Lite 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.

Gigabit LAN

The Gigabit Ethernet Controller supports data transmission at 1Gbps.

Audio

The audio codec provides High Definition audio output.

Wake-On-LAN

This feature allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. It is

supported via the onboard LAN port that uses the PCI PME (Power Management Event) signal.

However, if your system is in the Suspend mode, you can power-on the system only through an

IRQ or DMA interrupt.

Wake-On-USB

This function allows you to use a USB keyboard or USB mouse to wake up a system from the

S3 (STR - Suspend To RAM) state.

ACPI STR

The system board is designed to meet the ACPI (Advanced Configuration and Power

Interface) specification. ACPI has energy saving features that enables PCs to implement

Power Management and Plug-and-Play with operating systems that support OS Direct Power

Management. ACPI when enabled in the Power Management Setup will allow you to use the

Suspend to RAM function.

With the Suspend to RAM function enabled, you can power-off the system at once by pressing

the power button or selecting “Standby” when you shut down Windows®without having to go

through the sometimes tiresome process of closing files, applications and operating system.

This is because the system is capable of storing all programs and data files during the entire

operating session into RAM (Random Access Memory) when it powers-off. The operating

session will resume exactly where you left off the next time you power-on the system.

Power Failure Recovery

When power returns after an AC power failure, you may choose to either power-on the system

manually or let the system power-on automatically.

USB

The system board supports the new USB 3.1 Gen 1. It is capable of running at a maximum

transmission speed of up to 5 Gbit/s, or 625 MB/s. USB 3.1 reduces the time required for data

transmission, reduces power consumption, and is backward compatible with USB 2.0. It is a

marked improvement in device transfer speeds between your computer and a wide range of

simultaneously accessible external Plug and Play peripherals.

RTC Timer

The Real Time Clock (RTC) installed on the system board allows your system to automatically

power-on on the set date and time.

Chapter 2 - Hardware Installation

XBoard Layout

Note:

Some components are optional and only available upon request.

Important:

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

disk drives, add-in boards, and other components. Perform

installation procedures 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.

HARDWARE INSTALLATION

User's Manual | M8M051

Installing the Heat Sink

The CPU must be kept cool by using a heat sink, otherwise the CPU will overheat damaging

both the CPU and system board.

1. Before you install the fan / heat sink, you must apply a thermal paste onto the top of

the CPU. The thermal paste is usually supplied when you purchase the fan / heat sink

assembly. Do not spread the paste all over the surface. When you later place the heat

sink on top of the CPU, the compound will disperse evenly.

Some heat sinks come with a patch of pre-applied thermal paste. Do not apply thermal

paste if the fan / heat sink already has a patch of thermal paste on its underside. Peel

the strip that covers the paste before you place the fan / heat sink on top of the CPU.

2. Place the heat sink on top of the CPU. The 4 spring screws around the heat sink, which

are used to secure the heat sink onto the system board, must match the 4 mounting

holes around the board.

3. Screw tight two of the spring screws at opposite corners into the mounting holes. And

then proceed with the other two spring screws.
