1.4. Setting Up the Hardware

  1. Power down computer number 1.
  2. Plug the Intel® Stratix® 10 MX FPGA development kit card into a PCIe* slot that supports Gen3 x16.
  3. For the Intel® Stratix® 10 MX FPGA development kit, connectors J26 and J27 power the card. After inserting the card into an available PCIe* slot, connect 2x4- and 2x3-pin PCIe* power cables from the power supply of computer number 1 to the J26 and J27 connectors of the PCIe* card, respectively.
  4. Connect a USB cable from computer number 2 to the Intel® Stratix® 10 MX FPGA development kit. The development kit includes an on-board Intel FPGA Download Cable for FPGA programming.
  5. To power up the Intel® Stratix® 10 MX FPGA development kit via the PCIe* slot, power on computer number 1. Alternatively, you can power up the Intel® Stratix® 10 MX FPGA development kit using the external power adapter that ships with the kit.
  6. On computer number 2, bring up the Intel® Quartus® Prime programmer and configure the FPGA through an Intel FPGA Download Cable.
    Note: You must reconfigure the FPGA whenever the FPGA development kit loses power.
  7. To force system enumeration to discover the PCIe* device, restart computer number 1.
