 Wear an ESD-preventive wrist strap attached to a good earth ground

 Check the resistance value of the wrist strap periodically (1 MΩ to 10 MΩ)

 Transport and store the module in its antistatic bag

 Handle the module at an approved ESD workstation

 Handle the module only by the edges

To get the module running follow these steps. If the module shipped from KONTRON already has components like
RAM and CPU cooler mounted, then skip the relevant steps below.

An Intel® SDM ready display or power supply daughter card is required to proceed the
following steps.

In case of a display compatible with Intel® SDM specifications

1. Turn off the main power switch
Turn off the main power switch on the display and withdraw the module from the display if it has been installed.

2. Insert the DDR4 2400 / 2133 module(s)
Be careful to push the memory module(s) in the slot(s) before locking the tabs.

3. Connect interfaces
Install M.2 SSD if needed. Insert the module into the display. Connect all external cables for keyboard etc. in order
to change BIOS settings.

4. Power on the module
Turn on the main power switch on the display.

5. BIOS setup
Enter the BIOS setup by pressing the <DEL> key during boot up.
Enter "Exit Menu" and Load Setup Defaults.

In case of a power supply daughter card compatible with Intel® SDM specifications

1. Turn off the PSU (Power Supply Unit)

Turn off PSU (Power Supply Unit) completely (no mains power connected to the PSU) or
leave the Power Connectors unconnected while configuring the module if it has been
connected to the power supply daughter card. Otherwise, components (RAM, LAN cards
etc.) might get damaged. Make sure to use a proper PSU depending on the daughter card

3.6. System Memory Support

The SDML-WLU0 Series has two DDR4 SO-DIMM sockets. The sockets support the following memory features:

 2x DDR4 SO-DIMM 260-pin

 Dual-channel with 1x SO-DIMM per channel

 Up to 64 GB

 SPD timing supported

 ECC not supported

The installed DDR4 SO-DIMM should support the Serial Presence Detect (SPD) data structure. This allows the BIOS to
read and configure the memory controller for optimal performance. If non-SPD memory is used, the BIOS will attempt
to configure the memory settings, but performance and reliability may be impacted, or the module may not be able to
boot totally.

3.6.1. Memory Operating Frequencies

In all modes, the frequency of system memory is the lowest frequency of all the memory modules placed in the
system. Each memory module's frequency can be determined through the SPD registers on the memory modules.

The table below lists the resulting operating memory frequencies based on the combination of SO-DIMMs and
processor.

DDR4 2133 PC4-17000 2133 1067 267 17067

Memory modules have in general a much lower longevity than smart display modules, and therefore EOL of memory
modules can be expected several times during lifetime of the smart display modules.

As a minimum it is recommend using Kontron memory modules for prototype system(s) in order to prove stability of
the system and as for reference.

For volume production you might request to test and qualify other types of RAM. In order to qualify RAM it is
recommend configuring 3 systems running RAM Stress Test program in heat chamber at 60° C for a minimum of 24
hours.

3.8. Power Supply Voltage

In order to ensure safe operation of the module, the input power supply must monitor the supply voltage and shut
down if the supply is out of range -- refer to the actual power supply specification. Please note, in order to keep the
power consumption to a minimal level, modules do not implement a guaranteed minimum load. The SDML-WLU0
Series module must be powered through Intel® SDM compliant PCIe x8 edge connector from an Intel® SDM ready
display or power supply daughter card for DC 12 V and 3.3 VSB power supply.

The requirements to the supply voltages are as follows:
