About this Manual
Static Electricity Precautions
An electronic file of this manual is included in the CD. To view the user’s manual in the CD,
insert the CD into a CD-ROM drive. The autorun screen (Main Board Utility CD) will appear.
Click “User’s Manual” on the main menu.
Warranty
1. Warranty does not cover damages or failures that arised 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 consequencial damages to the
product that has been modified or altered.
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.

Features
• 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.
• DDR3
DDR3 delivers increased system bandwidth and improved performance. The advantages of
DDR3 are its higher bandwidth and its increase in performance at a lower power than DDR2.
• Graphics
The integrated Intel® GMA 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 DVI and VGA for up
to 2 independent displays.
• Gigabit LAN
The Intel® WG82574L Gigabit LAN controller supports up to 1Gbps data transmission.
• Audio
The Realtek ALC886 audio codec provides 7.1-channel High Definition audio output.
• Wake-On-LAN
• 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.
Important:
If you are using the Wake-On-USB Keyboard/Mouse function for 2 USB ports, the
5V_standby power source of your power supply must support ≥1.5A. For 3 or more
USB ports, the 5V_standby power source of your power supply must support ≥2A.
This feature allows the network to remotely wake up a Soft Power Down (Soft-Off) PC. It
is supported via the onboard LAN port or via a PCI LAN card that uses the PCI PME (Power
Management Event) signal. However, if your system is in the Suspend mode, you can poweron the system only through an IRQ or DMA interrupt.
Important:
The 5V_standby power source of your power supply must support ≥720mA.

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.
System Memory
Important:
When the Standby Power LED lit red, it indicates that there is power on the system
board. Power-off the PC then unplug the power cord prior to installing any devices.
Failure to do so will cause severe damage to the motherboard and components.

This DB-9 port can be used as an RS232/422/485 COM port or as an isolated 4-bit DIO. Refer
to the jumper setting in this section for its respective configuration.
COM2 (Serial) Port
The serial port is an asynchronous communication ports with 16C550A-compatible UARTs that
can be used with modems, serial printers, remote display terminals, and other serial devices.
Isolated 4-bit DIO (2-bit in and 2-bit out)
The isolated 4-bit Digital I/O connector provides powering-on function to external devices that
are connected to these connectors.

The board supports the chassis intrusion detection function. Connect the chassis intrusion
sensor cable from the chassis to this connector. When the system’s power is on and a chassis
intrusion occurred, an alarm will sound. When the system’s power is off and a chassis intrusion
occurred, the alarm will sound only when the system restarts.
MyGuard Hardware Monitor
Install the “MyGuard Hardware Monitor” utility. By default, the chassis intrusion detection function is disabled. When enabled, a warning message will appear when the chassis is open. The
utility can also be configured so that a beeping alarm will sound when the chassis is open.
Refer to the “MyGuard Hardware Monitor” section in chapter 4 for more information.
