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.

Warranty
1. Warranty does not cover damages or failures that arised from misuse of the product,
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
product that has been modified or altered.
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.
Battery:
• Danger of explosion if battery incorrectly replaced.
• Replace only with the same or equivalent type recommend by the manufacturer.
• Dispose of used batteries according to local ordinance.
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.

The VGA port is used for connecting a VGA monitor. Connect the monitor’s 15-pin D-shell cable
connector to the VGA port. After you plug the monitor’s cable connector into the VGA port,
gently tighten the cable screws to hold the connector in place.

Wake-On-USB Keyboard/Mouse
The Wake-On-USB Keyboard/Mouse function allows you to use a USB keyboard or USB mouse
to wake up a system from the S3 (STR - Suspend To RAM) state. If your module board supports this function, follow below jumper setting to use it:
• Jumper Setting
JP1 (for USB 3.0 ports 0,1) and JP2 (for USB 3.0 ports 2,3) must be set to “2-3 On: +5VDU”.
Refer to “USB Power Select” in this chapter for more information.
Important:
If your module board supports Wake-On-USB Keyboard/Mouse function, the +5V_
standby power source of your power supply must support ≥2A for 2 USB devices.
USB Ports
USB allows data exchange between your computer and a wide range of simultaneously accessible external plug-and-play peripherals.
The system board is equipped with 4 onboard USB 3.0 ports (USB 0,1/2,3). (Full function
depends on module board.)
Driver Installation
You may need to install the proper drivers in your operating system to use the USB device.
Refer to your operating system’s manual or documentation for more information.

The Low Pin Count Interface was defined by Intel® Corporation to facilitate the industry’s
transition towards legacy free systems. It allows the integration of low-bandwidth legacy I/O
components within the system, which are typically provided by a Super I/O controller. Furthermore, it can be used to interface firmware hubs, Trusted Platform Module (TPM) devices and
embedded controller solutions. Data transfer on the LPC bus is implemented over a 4 bit serialized data interface, which uses a 24MHz LPC bus clock. For more information about LPC bus
refer to the Intel
®
Low Pin Count Interface Specification Revision 1.1’. The table on the right
indicates the pin functions of the LPC connector.

Use a power supply that complies with the ATX12V Power Supply Design Guide Version 1.1.
An ATX12V power supply unit has a standard 24-pin ATX main power connector that must be
inserted into the 24-pin connector. The 4-pin +12V power connector enables the delivery of
more +12VDC current to the COM express module board and carrier board’s PCIe device.
The power connectors from the power supply unit are designed to fit the 24-pin and 4-pin
connectors in only one orientation. Make sure to find the proper orientation before plugging
the connectors.

Important:
The system board consumes a minimal amount of power. Due to its low power
consumption, you only need a 120W to 150W power supply. Every power supply has
its minimum load of power. If you use a greater than 150W power supply, the power
consumed by the system board may not attain its minimum load causing instability to
the entire system.
