4.8 Power on your Nuvo-2400
4.8.1 Power on Using the Power Button
This is the simplest way to turn on your system. The power button is a non-latched switch
and behaves the ATX-mode on/off control. As DC power is connected, push the power
button will turn on the system as well as the PWR LED indicator. Push the button when
system is on will turn off the system. If your operating system supports ATX power mode
(i.e. Microsoft Windows or Linux), push the power button causes a pre-defined system
behavior, such as shutdown or hibernation.
4.8.2 Power on Using an External Latched Switch
When using the AT-mode on/off control, you need a latched switch. The external latched
switch controls the feed-in of DC power. When the switch is closed, the DC power is
break-
off. When it’s opened, the DC power is feed
-in. To power on Nuvo-2400 using an
external latched switch (AT-mode), please follow the steps listed below:
1. Configure the
[Power On after Power Failure]
BIOS option as
[ON]
. Please refer to
section “
Power On after Power Failure Option
2. Prepare a latched switch with a 2-pin, 2.0mm pitch connector. Connect the latched
switch to the AT pin and GND pin of the on-board wafer connector.

3. When the latched switch is closed, the DC power is break off and system is turn off.
When the latched switch is opened, the DC power is feed-in, and the system is turn on.
