Soft Power Connector
The Soft Power Connector is located on pins 1 and 2 of jumper block J8. The
Tsunami AT uses the PIIX4e chip for power
management, including turning on and off the
system. If the Power Button Function option in the
Power Mangement Menu is set to On/Off (which is
the default), pressing the power button once, after
the BIOS has booted up, will turn the system on
and off. If the Power Button Function option is set
to Suspend, pressing the power button once will
wake the system or send it in to Suspend mode. In
this case, you cannot turn the system off unless
you shut down through the Windows operating
system or you hold the power button down for four
seconds. The soft power function requires an ATX
power supply.
Speaker Connector Installation
The Tsunami AT provides a 4-pin header to connect the speaker. The speaker
is connected to pins 24-27 of jumper block J8.
Hardware Reset Switch Connector
Installation
The Reset switch on your case's display panel provides you with the Hard-
ware Reset function, which is the same as power on/off. The system will do a
cold start after the Reset button is pushed. The Reset switch is a 2-pin
connector and should be installed on pins 22 and 23 of jumper block J8.
