NovaScale R422 Installation and User's Guide
This feature is available when the user enables the CPU overheating warning function in
the BIOS. This allows the user to de fi ne an overheat temperature. When the temperature
exceeds a user pre-de fi ned threshold, both overheat fan and warning LED are triggered.
5-11 ACPI Features
ACPI stands for Advanced Con fi guration and Power Interface. The ACPI speci fi cation
de fi nes a fl exible 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. This
also includes consumer devices connected to the PC such as VCRs, TVs, telephones and
stereos.
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 con fi guration 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 NT 5.0.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED 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 a power supply is used, the power button can function as a system suspend button
to make the system enter a SoftOff state. The monitor will be suspended and the hard drive
will spin down. Pressing the power button again will cause the whole system to wake up.
During the SoftOff state, the 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 Boot Features
Section under Advanced Setup in the BIOS.
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem ringing when
the system is in the SoftOff state. Note that external modem ring-on can only be used with
an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN (WOL)
Wake-On-LAN is de fi ned as the ability of a management application to remotely power up
a computer that is powered off. Remote PC setup, updates and asset tracking can occur
after hours and on weekends so that daily LAN traf fi c is kept to a minimum and users are
not interrupted. The motherboard has a 3-pin header (WOL) to connect to the 3-pin header
on a Network Interface Card (NIC) that has WOL capability. In addition, an onboard LAN
controller can also support WOL without any connection to the WOL header. The 3-pin
WOL header is to be used with a LAN add-on card only.
