Product Warranty (2 years)
Advantech warrants to you, the original purchaser, that each of its products will be
free from defects in materials and workmanship for two years from the date of pur-
chase.
This warranty does not apply to any products which have been repaired or altered by
persons other than repair personnel authorized by Advantech, or which have been
subject to misuse, abuse, accident or improper installation. Advantech assumes no
liability under the terms of this warranty as a consequence of such events.
Because of Advantech’s high quality-control standards and rigorous testing, most of
our customers never need to use our repair service. If an Advantech product is defec-
tive, it will be repaired or replaced at no charge during the warranty period. For out-
of-warranty repairs, you will be billed according to the cost of replacement materials,
service time and freight. Please consult your dealer for more details.
If you think you have a defective product, follow these steps:
1. Collect all the information about the problem encountered. (For example, CPU
speed, Advantech products used, other hardware and software used, etc.) Note
anything abnormal and list any onscreen messages you get when the problem
occurs.
2. Call your dealer and describe the problem. Please have your manual, product,
and any helpful information readily available.
3. If your product is diagnosed as defective, obtain an RMA (return merchandize
authorization) number from your dealer. This allows us to process your return
more quickly.
4. Carefully pack the defective product, a fully-completed Repair and Replacement
Order Card and a photocopy proof of purchase date (such as your sales receipt)
in a shippable container. A product returned without proof of the purchase date
is not eligible for warranty service.
5. Write the RMA number visibly on the outside of the package and ship it prepaid
to your dealer.

Safety Precaution - Static Electricity
Follow these simple precautions to protect yourself from harm and the products from
damage.
To avoid electrical shock, always disconnect the power from your PC chassis
before you work on it. Don't touch any components on the CPU card or other
cards while the PC is on.
Disconnect power before making any configuration changes. The sudden rush
of power as you connect a jumper or install a card may damage sensitive elec-
tronic components.

SOM-6898 User Manual 2
1.1 Introduction
SOM-6898 is a COM Express Compact module with type 6 pin-out that fully complies
with the PICMG (PCI Industrial Computer Manufactures Group) COM.0 R2.1 specifi-
cation. The CPU module uses an Intel 7th Generation Core i processor and other
peripheral chips in a basic size 95x95mm COM Express form factor. SOM-6898 fea-
tures a 15 watt TDP and is equipped with a power-saving ULV-SoC on new 14nm
micro architecture. SOM-6898 supports up to 32GB dual channel DDR4 2133 non-
ECC, with higher memory bandwidth for better performance. SOM-6898 is equipped
with an integrated Intel Gen 9 LP graphics micro architecture, supplying up to three
independently operated 4K displays via DisplayPort. It also supports HW accelerated
video decoding for AVC, VC1, MPEG2, HEVC, VP8, JPEG. SOM-6898 I/O includes
PCI Express Gen 3, 2 SATA G3, 4 USB 3.0, 8 USB 2.0. Moreover, 5 PCIe x1 (4 PCIe
x1 + 1 PCIe x4 (support up to 5 devices and 8 lanes) can be supported at a time to
make the IO design more flexible. In addition, SOM-6898 adds mounting holes
around the processor to strengthen the board structure and avoid board bending.
Advantech iManager was designed to satisfy a lot of embedded application require-
ments such as multi-level watchdog timer, voltage and temperature monitoring, and
thermal protection through processor throttling, as well as LCD backlight on/off,
brightness control, and embedded storage information. Combined with Advantech
SUSI Access, it can remotely monitor and control devices via the internet for easy
maintenance. All Advantech COM Express modules integrate iManager and SUSI
Access to benefit customer’s applications. SOM-6898 is suitable for computing inten-
sive, thermal sensitive, graphics/media intense, and I/O demanding applications.
