The VCU118 board power switch is SW5. Sliding the switch actuator from the off to the on position applies 12VDC power from the 6-pin mini-fit power input connector J16, normally used in bench-top applications with the provided power adapter. The green LED DS20 illuminates when the VCU128 board power switch is on. See Board Power System for details on the onboard power system. The following figure shows the power connector J16, power switch SW5, and indicator LED DS20.
When the VCU128 board is used inside a computer chassis (i.e., plugged in to a PCIe® slot), power is normally provided from the PC ATX supply 2x4 PCIe power connector. See Installing the Board in a PC Chassis.
