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 requires less voltage (1.35V) than DDR3 (1.5V). DDR3L SDRAM modules support
1867MHz for DDR modules.
• 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 x VGA, 1 x HDMI
and 1 x LVDS/eDP (eDP optional) interfaces for triple 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 Realtek RTL8111H-CG Ethernet controllers support up to 1Gbps data transmission.
• Audio
The Realtek ALC269Q audio codec provides 4-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 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.
• 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 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.
• 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.
