INTEGRATOR’S NOTES
• Use only ATX12V-compliant power supplies with these boards. ATX12V power supplies
have an additional power lead that provides required supplemental power for the
processor. Always connect the 20-pin and 4-pin leads of ATX12V power supplies to the
corresponding connectors on the board, otherwise the board will not boot.
• Do not use a standard ATX power supply. The board will not boot with a standard ATX
power supply.
