3.1. Applying Power to the Development Board

This development kit is designed to operate in two modes:

As a PCIe* Add-In Card

When operating the add-in card as a PCIe* end-point, insert the add-in card into an available PCIe* slot and connect a 2x4 pin PCIe* power cable from the system to power connectors at J11 of the board.

Note: When operating as a PCIe* add-in card, the board does not power on unless power is supplied to J11.

In Bench-Top Mode

In bench-top mode, you must supply the board with the provided 240 W power supply connected to the power connector J11. The following describes the operation in bench-top mode.

This development board ships with its switches preconfigured to support the design examples in the kit.

If you suspect that your board may not be correctly configured with the default settings, follow the instructions in the Default Switch Settings.

  1. Connect the supplied power supply to an outlet and the DC Power Jack (J11) on the FPGA board.
    Note: Use only the supplied power supply. Power regulation circuits on the board can be damaged by power supplies with greater voltage.
  2. Set the power switch (SW6) to the ON position.

    When the board powers up, the blue power LED illuminates and the board is ready for use.

The blue LED (D6) illuminates to indicate that all the power rails on the board are good. If the POWER GOOD LED (D6) is not illuminated, it indicates that the power supply malfunctioned, and the board does not power up.

CAUTION:
Standby powers are always present as soon as the Aux power is applied to J11. Use power switch SW6 to start the board.
