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-5894 User Manual 2
1.1 Introduction
SOM-5894 is a COM-Express Basic module with pin-out Type 6 that fully complies
with the PICMG (PCI Industrial Computer Manufactures Group) COM.0 R2.1 specifi-
cation. The CPU module incorporates an Intel 4th Generation Core i processor, PCH
QM87, and other peripheral chips. The Intel latest processor uses 22nm and 3D Tri-
gate transistor technologies that brings 13% performance improvement over previ-
ous versions, and integrates a powerful Intel HD Graphic 4600 as well as DX11.1,
OpenCL1.2, OpenGL4.0 API enabling better display configurations with no band-
width limitations. With Intel PCH QM87, SOM-5894 provides advanced interfaces
such as PCI Express Gen 3, SATA Gen 3, and USB3.0. Moreover, PCIe x16 can be
used in combination of x4 or x8 to make it more flexible.
Advantech iManager 2.0 was invented to satisfy a lot of embedded application
requirements such as multi-level watchdog timer, voltage and temperature monitor-
ing, thermal protection and mitigation through processor throttling, LCD backlight on/
off and brightness control, and embedded storage. Combining Advantech SUSI
Access, it can remotely monitor and control devices via the internet for easy main-
tainance. All Advantech COM Express modules integrate iManager and SUSI Access
to benefit our customer’s applications.
With top performance and lower power consumption, various extensions and I/O
interfaces, SOM-5894 is suitable for computing intensive design, thermal sensitive
design, graphics/media insensitive design, and I/O demanding applications.
