3.2. Powering Up the Development Kit
The Cyclone® 10 GX FPGA Development Kit has two modes of operation as described below.
In a Standard PCIe* -Compliant System
In this mode, plug the board into an available PCIe* slot and connect the standard 2×4 PCIe* auxiliary power available from the PC's ATX power supply to the mating connector on the board (J12), and remove any power supply connected to J13. The PCIe* slot together with the PCIe* power is required to power the entire board with power up to 75 watt. If the ATX power is not connected, ensure that your PCIe* system can provide up to 75 watt of power through the PCIe* slot alone. The power switch S14 is ignored when the board is used in the PCIe* .
As a Standalone Evaluation Board
In this mode, plug the included power supply into the power adapter connector (J13) and the AC power cord of the power supply into a power outlet. Remove any ATX power supply that is connected from the 2×4 power connector (J12). The power switch S14 powers ON/OFF the board.
