Power On/Off Slide Switch
[Figure 2-1, callout 22]
The ZCU104 board power switch is SW1. Sliding the switch actuator from the off to the on
position applies 12V power from J52, a 6-pin mini-fit connector. Green LED DS2 illuminates
when the ZCU104 board power is on. See Board Power System, page 83 for details on the
on-board power system.
CAUTION! Do NOT plug a PC ATX power supply 6-pin connector into the ZCU104 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 ZCU104 board and voids the board warranty.
Figure 3-29 shows the power connector J52, power switch SW1, and LED indicator DS2.
