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 is a higher performance DDR3 SDRAM interface providing less voltage and higher

speed successor. DDR3L SDRAM modules support 1333/1600MHz for DDR modules. DDR3L de-

livers 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 out-

standing graphics responsiveness. These enhancements deliver the performance and compat-

ibility needed for today’s and tomorrow’s business applications. Supports 1 LVDS and 2 DP

(default);or2HDMI(optional)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

®

I210 PCI Express Gigabit Ethernet and Intel

®

I218 with iAMT9.5 Gigabit Ethernet Phy

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 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

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:
