Power On/Off Slide Switch

[Figure 1-2, callout 20]
The ZC702 board power switch is SW11. Sliding the switch actuator from the Off to On
position applies 12V power from J60, a 6-pin mini-fit connector. Green LED DS14
illuminates when the ZC702 board power is on. See
onboard power system.
Do NOT plug a PC ATX power supply 6-pin connector into J60 on the ZC702 board. The ATX
CAUTION!
6-pin connector has a different pinout than J60. Connecting an ATX 6-pin connector into J60 will
damage the ZC702 board and void the board warranty.
Figure 1-26 shows the power connector J60, power switch SW11 and indicator LED DS14.
