3/ Installation procedure
3.1. Installing the Board
ESD Sensitive Device!
Electrostatic discharge (ESD) can damage equipment and impair electrical circuitry.
To get the board running follow these steps. If the board shipped from Kontron has already components like RAM
and CPU cooler mounted, then relevant steps below can be skipped.
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 board. Otherwise
components (RAM, LAN cards etc.) might get damaged. Make sure to use +12 V single supply
only.
The power supply unit shall comply with the requirements as defined in IEC 62368-1
according Clause 6.2.2 to power source category PS2 "Limited Power Source".
2.
Cooler Installation
Normally the cooler is pre-mounted, but in case not, then make sure that the heat paste etc. on the cooler is
intact. Remove plastic foil from heat paste before mounting the cooler. Check for correct orientation. Connect
cooler fan electrically to the FAN_CPU connector. We recommend 4 times M3x10 mm male-female standoffs to
fix cooler to the SBC. This gives sufficient space for any M.2 modules.
3.
Mounting the board in chassis
When mounting the board to chassis etc. please notice that the board contains components
on both sides of the PCB which can easily be damaged if board is handled without
reasonable care. A damaged component can result in malfunction or no function at all.
When fixing the Motherboard on a chassis it is recommended to use screws with integrated washer and a
diameter of < 5.5 mm. Do not use washers with teeth, as they can damage the PCB and cause short circuits.
4.
Connecting Interfaces
Insert all external cables for keyboard, COM, etc. A terminal must be connected in order to change U-Boot
settings.
•
Wear ESD-protective clothing and shoes
•
Wear an ESD-preventive wrist strap attached to a good earth ground
•
Check the resistance value of the wrist strap periodically (OK: 1 MΩ to 10 MΩ)
•
Transport and store the board in its antistatic bag
•
Handle the board at an approved ESD workstation
•
Handle the board only by the edges
