This equipment has been tested and found to comply with the limits for a Class B digital
device, pursuant to Part 15 of the FCC rules. These limits are designed to provide reason-
able protection against harmful interference when the equipment is operated in a residential
installation. This equipment generates, uses and can 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 television
reception, which can be determined by turning the equipment off and on, the user is encour-
aged 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.

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 instal-
lation, modification, accidents or unauthorized repair of the product.
3. Unless otherwise instructed in this user’s manual, the user may not, under any circum-
stances, 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

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 han-
dling 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 con-
nectors by their ends.
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 installa-
tion or servicing. After installation or servicing, cover the system chassis before
plugging the power cord.
Important:
Electrostatic discharge (ESD) can damage your processor, disk drive and other com-
ponents. Perform the upgrade instruction procedures described at an ESD worksta-
tion 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 chas-
sis. If a wrist strap is unavailable, establish and maintain contact with the system
chassis throughout any procedures requiring ESD protection.

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 out-
standing graphics responsiveness. These enhancements deliver the performance and compat-
ibility needed for today’s and tomorrow’s business applications. Supports DVI-I 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
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 power-
on the system only through an IRQ or DMA interrupt.
Chapter 1
• 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:
The 5V_standby power source of your power supply must support ≥720mA.
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.

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 wear-
ing 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.
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.

button, set pins 1 and 3 to On.
When using the JP5 “Power On” feature to power the system back on after a power failure
occurs, the system may not power on if the power lost is resumed within 5 seconds (power
flicker).
Note:
In order to ensure that power is resumed after a power failure that recovers within a
5 second period, JP5 must be set to pins 3-5 and the “AC Power Lose” in CMOS is set
to “On”.

RS232/422/485 COM2
or Isolated 4-bit DIO
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.

Chassis Intrusion Connector
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 func-
tion 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.

Cooling Fan Connectors
The fan connectors are used to connect cooling fans. The cooling fans will provide adequate
airflow throughout the chassis to prevent overheating the CPU and system board components.
BIOS Setting
The Advanced menu (“Hardware Health Configuration” submenu) of the BIOS will display the
current speed of the cooling fans. Refer to chapter 3 for more information.
