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 installation or servic-
ing. 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.

Chapter 1 Introduction
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.
• DDR4
DDR4 deliver increased system bandwidth and improved performance. The advantages of
DDR4 are its higher bandwidth and its increase in performance at a lower power than DDR3
and DDR3L. It is not compatible with older standards of DDR memories.
• 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 out-
standing graphics responsiveness. These enhancements deliver the performance and compat-
ibility needed for today’s and tomorrow’s business applications. Supports 1 LVDS (or eDP), 1
DisplayPort (or HDMI) and 1 VGA interfaces for display outputs.
• Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification. With speed of
up to 6Gb/s (SATA 3.0), it improves hard drive performance faster than the standard parallel
ATA whose data transfer rate is 100MB/s.
• Gigabit LAN
Two Intel
®
Gigabit LAN controllers (Intel
®
I210AT PCI Express Gigabit Ethernet controller and
Inte
I219LM Gigabit Ethernet Phy) support up to 1Gbps data transmission.
• Audio
The Realtek ALC888S-VD2-GR audio codec provides 5.1-channel High Definition audio output.
• 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 3.0. It is capable of running at a maximum transmis-
sion speed of up to 5 Gbit/s (625 MB/s) and is faster than USB 2.0 (480 Mbit/s, or 60 MB/s)
and USB 1.1 (12Mb/s). USB 3.0 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.
Important:
The 5V_standby power source of your power supply must support 720mA.
• Wake-On-USB (optional)
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 Manage-
ment 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 ses-
sion will resume exactly where you left off the next time you power-on the system.
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.
• 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 Man-
agement Event) signal. However, if your system is in the Suspend mode, you can power-on
the system only through an IRQ or DMA interrupt.
Important:
The 5V standby power source of your power supply must support 720mA.
• RTC Timer
The RTC installed on the system board allows your system to automatically power-on on the
set date and time.

System CPU
The system board is equipped with a Skylake-U microprocessor in socket BGA compatible
package 1356.
Installing the Heat Sink
The CPU must be kept cool by using a CPU fan with heat sink. Without sufficient air circula-
tion across the CPU and heat sink, 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 assem-
bly. 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 captive
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 CPU on
the system board.
2. Use the standoffs and captive
screws to fasten the heat sink on
the system board.

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 lights red, it indicates that there is power on the sys-
tem board. Power-off the PC then unplug the power cord prior to installing any de-
vices. Failure to do so will cause severe damage to the motherboard and components.

DC-in
This 2-pin terminal block provides maximum of 100W/120W power and is considered a low
power solution. Connect a DC power cord to this terminal block. Using a voltage more than
the recommended range may fail to boot the system or cause damage to the system board.
Graphics Interfaces
VGA Port
The VGA port is used for connecting a VGA monitor. Connect the monitor’s 15-pin D-shell cable
connector to the VGA port. After you plug the monitor’s cable connector into the VGA port,
gently tighten the cable screws to hold the connector in place.
DP Port
The DP port is a digital display interface used to connect a display device such as a computer
monitor. It is used to transmit audio and video simultaneously. The interface, which is devel-
oped by VESA, delivers higher performance features than any other digital interface.
HDMI Port (optional)
The HDMI port which carries both digital audio and video signals is used to connect a LCD
monitor or digital TV that has the HDMI port.
BIOS Setting
Configure the display devices in the Chipset menu (“North Bridge Configuration” submenu) of
the BIOS. Refer to the chapter 3 for more information.

ously accessible external Plug and Play peripherals.
The system board is equipped with four onboard USB 3.0 port (USB 1-4). The 10-pin connec-
tor allows you to connect 2 additional USB 2.0 port (USB 1-2). The additional USB port may be
mounted on a card-edge bracket. Install the card-edge bracket to an available slot at the rear
of the system chassis and then insert the USB port cables to a connector.
BIOS Setting
Configure the onboard USB in the Advanced menu (“USB Configuration” submenu) of the
BIOS. Refer to chapter 3 for more information.
Driver Installation
You may need to install the proper drivers in your operating system to use the USB device.
Refer to chapter 4 for more information.
Wake-On-USB Keyboard/Mouse
The Wake-On-USB Keyboard/Mouse 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.
