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 internal modem, 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.

Introduction

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 por t, 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.

Wake-On-Keyboard/Mouse

This function allows you to use the keyboard or mouse to power-on the system.

Important:

The 5VSB power source of your power supply must support

The system board is equipped with an onboard serial port (CN6 Teal/Turquoise) for COM 1 and a 9-pin connector at location J17 for COM 2.

One card-edge bracket, mounted with a serial port cable, is provided with the system board. If you want to use the COM 2 serial port, connect the serial port cable to connector J17. Make sure the colored stripe on the ribbon cable is aligned with pin 1 of connector J17. Mount the card-edge bracket to the system chassis.

BIOS Setting

Select the serial ports’ I/O address in the Integrated Peripherals submenu (“Onboard Super IO Device” field) of the BIOS. Refer to chapter 3 for more information.
