Acpi Features; Power Supply - Viglen Vig410p Manual

ACPI Features:

ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible and abstract hardware interface that provides a
standard way to integrate power management features throughout a PC system,
including its hardware, operating system and application software. This enables the
system to automatically turn on and off peripherals such as CD-ROMs, network
cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI
provides a generic system event mechanism for Plug and Play and an operating
system-independent interface for configuration control. ACPI leverages the Plug and
Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with both Windows 2000 and Windows 2003
Operating Systems.
 Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED and LE1 will start
blinking to indicate that the CPU is in suspend mode. When the user presses any
key, the CPU will wake-up and the LED will automatically stop blinking and remain
on.
 Main Switch Override Mechanism
When an ATX power supply is used, the power button may function as a system
suspend button, allowing the system to enter a Soft Off state. The monitor will be
suspended and the hard drive will spin down. Pressing the power button again to
"wake-up" the whole system. During the Soft Off state, the ATX power supply
provides power to keep the required circuitry in the system "alive." In case the
system malfunctions and you want to turn off the power, just press and hold the
power button for 4 seconds. This option can be set in the BIOS Setup utility.

Power Supply:

Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the Standby or Off state. Note that external modem ring-on
can only be used with an ATX 2.01 (or above) compliant power supply.
The Vig410P can accommodate 24-pin ATX power supplies. Although most power
supplies generally meet the specifications required by the CPU, some are
inadequate. In addition, the two 12V 8-pin power connections are also required to
ensure adequate power supply to the system. Also your power supply must supply
1.5A for the Ethernet ports.
It is strongly recommended that you use a high quality power supply that meets ATX
power supply Specification 2.02 or above. It must also be SSI compliant. (For more
