1-5 ACPI Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI specifica -
tion 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 operating_system-directed power management, ACPI also 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 Windows 7, Windows 8, and Windows 2008
Operating Systems.
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 the suspend mode. When the user presses any key,
the CPU will "wake up," and the LED will automatically stop blinking and remain on.
1-6 Power Supply
As with all computer products, a stable power source is necessary for proper and
reliable operation. It is even more important for processors that have high CPU
clock rates.
The X9DRFF-iG+/iTG+/7G+/7TG+ motherboard supports two 8-pin and one 4-pin
power supplies. Although most power supplies generally meet the specifications
required by the CPU, some are inadequate. All these power connections are re-
quired for Fat Twin use only.
Note: To ensure adequate power to the system, SMC-proprietary power
backplanes or adaptors may be required. Refer to the server user's manual
that came with your system for detailed instructions on power supply
recommendations.
