1-5 ACPI Features
ACPIstandsforAdvancedCongurationandPowerInterface.TheACPIspecica-
tion denes a 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.
In addition to enabling operating system-directed power management, ACPI also
provides a generic system event mechanism for Plug and Play, and an operating
system-independentinterfaceforcongurationcontrol.ACPIleveragesthePlugand

Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start to blink
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.
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. This motherboard draws power from the backplane. Make sure that power
coming from the backplane and chassis is enough to power this motherboard and
the other nodes that reside in the same chassis.
It is strongly recommended that you use a high quality power supply that meets ATX

areas where noisy power transmission is present, you may choose to install a line
