2/ Installation Procedures
2.1. Chassis Compliance
Before installing the mITX-SKL-H in the chassis, users must evaluate the chassis to ensure compliance with the
requirements of the IEC60950-1 safety standard:
The motherboard must be installed in a suitable mechanical, electrical and fire enclosure.
The system, in its enclosure, must be evaluated for temperature and airflow considerations.
The motherboard must be powered by a CSA or UL approved power supply that limits the maximum input
current to 10 A via an external barrel-type +12 V to +24 V DC Jack, or to 16 A via an internal square
ATX +12 V 4-pin connector.
For interfaces having a power pin such as external power or fan, ensure that the connectors and wires are
suitably rated. All connections from and to the product shall use Safety Extra Low Voltage (SELV) circuits only.
Wires must have suitable ratings to withstand the maximum available power.
The enclosure of the peripheral device fulfils IEC60950-1's fire protection requirements.
2.2. 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 already has components like RAM
and CPU cooler mounted, then skip the relevant steps below.
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 a +12 V to +24 V DC
single supply only. Alternatively, use a standard ATX PSU with suitable cable kit and PS_ON#
active.
2.
Insert the DDR4 1866/2133 module(s)
Be careful to push the memory module in the slot(s) before locking the tabs. For a list of approved DDR4
SO-DIMMs, see Chapter 4.6 System Memory or contact your Distributor or FAE.
3.
Cooler Installation
The mITX-SKL-H comes with a pre-installed cooler.
4.
Connecting Interfaces
Insert all external cables for hard disk, keyboard etc. A monitor must be connected in order to change BIOS
settings.
5.
Connect and turn on PSU
Connect PSU to the board by the ATX+12 V- 4-pin connector or DC Jack.
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 (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
