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-5992 User Manual 2
1.1 Introduction
SOM-5992, designed around the Intel® Xeon® Processor D-1500 family, brings the
performance and advanced intelligence of Intel® Xeon® processors into a dense,
low-power system-on-a-chip. With enhanced reliability, availability, and serviceability
features, platform storage extensions, and built-in hardware virtualization, the Intel®
Xeon® processor D-1500 product family offers new possibilities for a variety of appli-
cations. SOM-5992 is suitable for midrange routers, network appliances, security
appliances, wireless base stations, embedded midrange IoT devices, entry network-
ing, midrange storage area networks (SANs), network attached storage (NAS) appli-
ances, warm cloud storage, and more.
In a breakthrough move, SOM-5992 supports a maximum of 64 GB DDR4 memory
which should help fulfill the ever-increasing server application demands in the area of
COM Express. The Intel® Xeon® processor D-1500 delivers 16 processor cores and
64 GB memory, combined with computer on module flexibility, this is an optimal solu-
tion for users who want extreme computing performance and non-stop service.
Moreover, the SOM-5992 incorporates two 10GBase-KR interfaces for integrating
with 10GbE customer carrier boards. PCIe x16 and 8 PCIe x1 Supports Non-Trans-
parent Bridge (NTB), which allows redundancy via PCIe. This helps reduce data loss,
allowing a secondary system to take over PCIe storage device management if a CPU
fails, and provides high availability for applications requiring continuous service.
SOM-5992 has four screw holes near the CPU, positioned in compliance with the
Intel® standard thermal design guide. The thermal module is attached to the CPU in
a balanced torque design, and it is the first COM Express to have an added back-
plane to increase rigidity like single board, so the thermal module makes tight contact
with the CPU with no board bending. This result is highly efficient heat dissipation
with outstanding computing performance. Advantech also offers SOM-5992-thermal-
solution pre assembly service that can assist in system-level assembly.

BIOS
The BIOS chip is on the module by default. This also allows users to place the
BIOS chip on the carrier board with an appropriate design and jumper setting on
BIOS_DIS#[1:0].
Power Management
Power Supply

optional if standby is not required (suspend-to-RAM). Supports RTC Battery as
optional if keep time/date is not required.

RTC Battery Power: 2.0V – 3.3V
PWROK
From the main power supply, a high value indicates that the power is good. This
signal can be used to hold off module startup to allow carrier based FPGAs or
other configurable devices time to be programmed.
Power Sequence
According to PICMG COM Express R3.0 specification
Wake Event
Various wake-up events support for different scenarios.
Wake-on-LAN(WOL): Wake to S0 from S4/S5
USB Wake: Wake to S0 from S4
PCIe Device Wake: depends on user inquiry and may need customized BIOS
LPC Wake: depends on user inquiry and may need customized BIOS
Advantech S5 ECO Mode (Deep Sleep Mode)
Advantech iManager provides additional features to allow the system to enter a very
low suspend power mode – S5 ECO mode. In this mode, the module will cut all
power including suspend and active power into the chipset and keep an on-module
controller active. Therefore, only under 50mW power will be consumed which means
the user’s battery pack will last a longer time. With this mode enabled in BIOS, the
system (or module) will only allow a power button to boot rather than others such as
WOL.
BIOS_DIS0# BIOS_DIS#1 Boot up destination/function
Open Open Boot from module’s SPI BIOS
GND Open Boot from carrier board LPC/FWH BIOS
Open GND SPI_CS0# to carrier board, SPI_CS1# to module
GND GND SPI_CS0# to module, SPI_CS1# to carrier board
Note! If system COMs are cleared, we strongly suggest to go to the BIOS
setup menu and load default settings at the first time of boot up.

OS Support (duplicate with SW chapter)
The mission of Advantech Embedded Software Services is to "Enhance quality of life
with Advantech platforms and Microsoft Windows embedded technology." We enable
Windows Embedded software products on Advantech platforms to more effectively
support the embedded computing community. Customers are freed from the hassle
of dealing with multiple vendors (Hardware suppliers, System integrators, Embedded
OS distributor) for projects. Our goal is to make Windows Embedded Software solu-
tions easily and widely available to the embedded computing community.
To install the drivers for Linux or other OS, please connect to the internet to download
the setup file.

Pin Description
Advantech provides useful checklists for schematic design and layout routing. In
schematic checklist, it will specify details about each pins electrical properties and
how to connect for different uses. In layout checklist, it will specify the layout con-
strains and recommendations for trace length, impedance, and other necessary infor-
mation during design.
Please contact your nearest Advantech branch office or call for getting the design
documents and further advanced support.
