FCC and DOC Statement on Class B

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 reason­able 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 encour­aged 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 compli­ance 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.

inability to use the product, unauthorized replacement or alteration of components and
product specifications.

2. The warranty is void if the product has been subjected to physical abuse, improper instal­lation, modification, accidents or unauthorized repair of the product.

3. Unless otherwise instructed in this user’s manual, the user may not, under any circum­stances, 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 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.

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.

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.

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 delivers increased system bandwidth and improves performance. The advantages of
DDR4 provide an extended battery life and improve the performance at a lower power than
DDR3/DDR2.

• 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 x HDMI, 1 x DVI-I
(DVI-D signal) and 1 x DP++ interfaces for triple display outputs.

• PCI Express

PCI Express is a high bandwidth I/O infrastructure that possesses the ability to scale speeds
by forming multiple lanes. The PCI Express architecture also supports high performance graph­ics infrastructure by enhancing the capability of a PCIe x16 Gen 3 at 16GB/s bandwidth.

• 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® I211AT PCIe and Intel® I219LM PCIe with iAMT12.0 (only Xeon, Core i7/i5 supports
iAMT) Gigabit LAN controllers support up to 1Gbps data transmission.

• Audio

The Realtek ALC888S-VD2-GR audio codec provides 5.1-channel High Definition audio output.

• Wake-On-PS/2

This function allows you to use the PS/2 keyboard or PS/2 mouse to power-on the system.

Important:

The 5V_standby power source of your power supply must support ≥720mA.

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.

• RTC Timer

The RTC installed on the system board allows your system to automatically power-on on the
set date and time.

• 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:

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 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.

8

• 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 3.1 Gen 2. It is capable of running at a maximum
transmission speed of up to 10 Gbit/s (1.2 GB/s) and is faster than USB 3.1 Gen 1 (5 Gbit/s,
or 625 MB/s), USB 2.0 (480 Mbit/s, or 60 MB/s) and USB 1.1 (12Mb/s). USB 3.1 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.

Features

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.

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.
