ATX power control Connector: CN3
When used with an ATX-compliant power supply that supports remote power on/off, the product can turn
off the system power through software control.
When using the ATX power supply, connect this connector to the ATX power control connector on the
backplane, using the attached cable.
To enable soft-off control in software, advanced power management must be enabled in the Setup
program and in the operation system. When the system BIOS receives the correct APM command from
the operating system, the BIOS turns off power to the computer.
