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.
• DDR3L
DDR3L is a higher performance DDR3 SDRAM interface providing less voltage and higher
speed successor. DDR3L SDRAM modules support 1066/1333MHz for DDR modules. DDR3L delivers increased system bandwidth and improved performance to provide its higher bandwidth
and its increase in performance at a lower power.
• 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 outstanding graphics responsiveness. These enhancements deliver the performance and compatibility needed for today’s and tomorrow’s business applications. Supports 1 LVDS, 1 HDMI and
1 VGA (default); or 1 DVI-I (optional) interface for display outputs.
• Serial ATA
Serial ATA is a storage interface that is compliant with SATA 1.0a specification. With speed of
up to 3Gb/s (SATA 2.0), it improves hard drive performance faster than the standard parallel
ATA whose data transfer rate is 100MB/s.
• Gigabit LAN
Two Intel® I210 Gigabit LAN controllers support up to 1Gbps data transmission.
• Audio
The Realtek ALC888 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 transmission 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.

• 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.
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.
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.
• 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 Management 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 session will resume exactly where you left off the next time you power-on the system.
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.

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 lights 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.

you can reconfigure the system with the default values stored in the ROM BIOS.
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 JP24 pins 2 and 3 to On. Wait for a few seconds and set JP24 back to its default setting, pins 1 and 2 On.
3. Now plug the power cord and power-on the system.
Chapter 2 Hardware Installation
JP25 is used to select the method of powering on the system. If you want the system to
power-on whenever AC power comes in, set JP25 pins 2 and 3 to On. If you want to use the
power button, set pins 1 and 2 to On.
When using the JP25 “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).
