Power On/Off Slide Switch
[Figure 2-1, callout 29]
The ZCU111 board power switch is SW1. Sliding the switch actuator from the off to on
position applies 12V power from J52, a 6-pin mini-fit connector. Green LED DS19
illuminates when the ZCU111 board power is on. See Board Power System for details on the
on-board power system.
CAUTION! Do NOT plug a PC ATX power supply 6-pin connector into the ZCU111 board power
connector J52. The ATX 6-pin connector has a different pin-out than J52. Connecting an ATX 6-pin
connector into J52 damages the ZCU111 board and voids the board warranty.
