Watchdog Timer

The Watchdog Timer function allows your application to regularly
“clear” the system at the set time interval. If the system hangs or
fails to function, it will reset at the set time interval so that your
system will continue to operate.

Dual Function Power Button

Depending on the setting in the “Soft-Off By PWR-BTTN” field of
the Power Management Setup, this switch will allow the system to
enter the Soft-Off or Suspend mode.

Wake-On-Ring

This feature allows the system that is in the Suspend mode or Soft
Power Off mode to wake-up/power-on to respond to calls coming
from an external modem or respond to calls from a modem PCI
card that uses the PCI PME (Power Management Event) signal to
remotely wake up the PC.

Important:
If you are using a modem add-in card, the 5VSB power source
of your power supply must support a minimum of

720mA.

Wake-On-LAN

This feature allows the network to remotely wake up a Soft Power
Down (Soft-Off) PC. It is supported via the onboard LAN port, via
a PCI LAN card that uses the PCI PME (Power Management Event)
signal or via a LAN card that uses the Wake-On-LAN connector.
However, if your system is in the Suspend mode, you can power-on
the system only through an IRQ or DMA interrupt.

Important:
The 5VSB power source of your power supply must support

720mA.
