3.2.1. Default Setting

The Intel® Agilex™ I-Series FPGA Development Kit ships with its board switches preconfigured to support the design examples in the kit. If you suspect your board might not be correctly configured with the default settings, follow the instructions in the Table 4 to return to its factory settings before proceeding.

4: Not used X X
SW6 ON/OFF

When the board is not in a PCIe* slot, it must be powered by an external power supply. The SW6 switch turns on the power of the board when it is at the ON position and turns off the power when it is at the OFF position.

When the board is in a PCIe* slot, the external and auxiliary power supplies must still be connected. The SW6 switch can be left at either the ON or OFF position. The board can only be powered on when both power sources are present.
