3.7.2 Powering On Using An External Non-Latched Switch
For an application which places the system inside a cabinet, it’s useful to control
powering on/off the system using an external switch. The system provides an
on-board connector for connecting a latched/ non-latched switch and behaving either
AT-mode or ATX-mode power on/off control.
When using the ATX-mode on/ off control, you need a non-latch switch. The external
non-latched switch acts exactly the same as the power button on the front panel
Please follow the steps below to install an external non-latch switch.
1. Prepare a non-latched switch with a 2-pin, 2.0mm pitch connector
2. Connect the non-latched switch to the pin#2 and pin#3 of the on-board 1x3
pins, 2.0mm pitch pin header (polarity is negligible). Press the button on the
switch to turn on the system.
