CAUTION! Do NOT plug a PC ATX power supply 6-pin connector into the ZCU670 board power
connector J50. The ATX 6-pin connector has a different pinout than J50. Connecting an ATX 6-pin
connector into J50 damages the ZCU670 board and voids the board warranty.
The following figure shows the power connector J50, power switch SW2, and LED indicator
DS19.
