Power On/Off Slide Switch
[Figure 2, callout 24]
The ZCU208 board power switch is SW15. Sliding the switch actuator from the off to on position
applies 12V power from J50, a 6-pin mini-fit connector. Green LED (DS19) illuminates when the
ZCU208 board power is on. See
CAUTION! Do NOT plug a PC ATX power supply 6-pin connector into the ZCU208 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 ZCU208 board and voids the board warranty.
The following figure shows the power connector J50, power switch SW2, and LED indicator
DS19.
