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.
Notice:
1. The changes or modifications not expressly approved by the party responsible for compli-
ance could void the user’s authority to operate the equipment.
2. Shielded interface cables must be used in order to comply with the emission limits.

ability to use the product, unauthorized replacement or alteration of components and prod-
uct 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 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.

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.
• DDR3L
DDR3L SDRAM provides backward compatibility to DDR3 memory modules but can operate at
the same or at a lower power level.
• 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 1VGA, 1 LVDS and 1
DP++ 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
Intel®I210AT PCI Express Gigabit Ethernet controller and Intel® I219LM PCI Express Gigabit
Ethernet controller with iAMT11.0 support up to 1Gbps data transmission.
• Audio
The Realtek ALC888S-VD2-GR audio codec provides 2.1-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 enable PCs to implement power manage-
ment and plug-and-play with operating systems that support power management features.
With ACPI, the system can further utilize the Ethernet adapter’s wake-on-LAN (WOL) capability
that enables remote wake-up if the Ethernet adapter supports such feature.
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.

Clear CMOS Data
If you encounter the following conditions, you can reconfigure the system with the default val-
ues stored in the ROM BIOS.
a) CMOS data becomes corrupted.
b) You forgot the supervisor or user password.
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 JP1 pins 2 and 3 to On. Wait for a few seconds and set JP1 back to its default setting,
pins 1 and 2 On.
3. Now plug the power cord and power-on the system.

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 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.
