For Your Safety
Your new Kontron product was developed and tested carefully to provide all features necessary to ensure its
compliance with electrical safety requirements. It was also designed for a long fault-free life. However, the life
expectancy of your product can be drastically reduced by improper treatment during unpacking and installation.
Therefore, in the interest of your own safety and of the correct operation of your new Kontron product, you are
requested to conform with the following guidelines.
High Voltage Safety Instructions
As a precaution and in case of danger, the power connector must be easily accessible. The power connector is the
product’s main disconnect device.
Warning
All operations on this product must be carried out by sufficiently skilled personnel only.
Electric Shock!
Before installing a non hot-swappable Kontron product into a system always ensure that
your mains power is switched off. This also applies to the installation of piggybacks. Serious
electrical shock hazards can exist during all installation, repair, and maintenance operations
on this product. Therefore, always unplug the power cable and any other cables which
provide external voltages before performing any work on this product.
Earth ground connection to vehicle’s chassis or a central grounding point shall remain
connected. The earth ground cable shall be the last cable to be disconnected or the first
cable to be connected when performing installation or removal procedures on this product.
Special Handling and Unpacking Instruction
ESD Sensitive Device!
Electronic boards and their components are sensitive to static electricity. Therefore, care
must be taken during all handling operations and inspections of this product, in order to
ensure product integrity at all times.
Do not handle this product out of its protective enclosure while it is not used for operational purposes unless it is
otherwise protected.
Whenever possible, unpack or pack this product only at EOS/ESD safe work stations. Where a safe work station is
not guaranteed, it is important for the user to be electrically discharged before touching the product with his/her
hands or tools. This is most easily done by touching a metal part of your system housing.
It is particularly important to observe standard anti-static precautions when changing piggybacks, ROM devices,
jumper settings etc. If the product contains batteries for RTC or memory backup, ensure that the product is not
placed on conductive surfaces, including anti-static plastics or sponges. They can cause short circuits and damage
the batteries or conductive circuits on the product.

5/ Connectors
5.1. Hardware Configuration Setting
This chapter gives the definitions and shows the positions of jumpers, headers and connectors. All of the
configuration jumpers on the board are in the proper position. The default settings shipped from factory are marked
with an asterisk (*).
In general, jumpers on the board are used to select options for certain features. Some of the jumpers are designed to
be user-configurable, allowing for system enhancement. The others are for testing purpose only and should not be
altered. To select any option, cover the jumper cap over (SHORT) or remove (NC) it from the jumper pins according to
the following instructions. Here, NC stands for “Not Connect”.

5.5. Thermal Management, Heatspreader and Cooling Solutions
A heatspreader plate assembly is available from Kontron for the SMARC sXCAL (2). The heatspreader plate on top of
this assembly is NOT a heat sink. It works as a SMARC-standard thermal interface to use with a heat sink or external
cooling devices.
Figure 7: Heatspreader as cooling solution
External cooling must be provided to maintain the heatspreader plate at proper operating temperatures. Under
worstcase conditions, the cooling mechanism must maintain an ambient air and heatspreader plate temperature on
any spot of the heatspreader's surface according the module specifications:
60°C for commercial grade modules
75°C for extended temperature grade modules (E1)
85°C for industrial temperature grade modules (E2/XT)
The aluminum slugs and thermal pads or the heat-pipe on the underside of the heatspreader assembly implement
thermal interfaces between the heatspreader plate and the major heat-generating components. About 80 % of the
power dissipated within the module is conducted to the heatspreader plate and can be removed by the cooling
solution. Documentation and CAD drawings of heatspreader and cooling solutions are provided at
http://emdcustomersection.kontron.com.
