1.5 ACPI Features

The Advanced Configuration and Power Interface (ACPI) defines a flexible and abstract
hardware interface that provides a standard way to integrate power management features
throughout a computer 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-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
appropriate Windows operating systems. For detailed information regarding OS support,
please refer to the Supermicro website.
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 where
noisy power transmission is present.
The X13SAE/X13SAE-F motherboard accommodates a 24-pin ATX power supply. Although
most power supplies generally meet the specifications required by the CPU, some are
inadequate. In addition, one 12V 8-pin power connection is also required to ensure adequate
power supply to the system. Also, your power supply must supply 1.5A for the Ethernet ports.
Warning: To avoid damaging the power supply or the motherboard, be sure to use a
power supply that contains a 24-pin and an 8-pin power connector. Be sure to con-
nect the power supplies to the 24-pin power connector (JPW1), and the 8-pin power
connector (JPW2) on the motherboard. Failure in doing so may void the manufacturer
warranty on your power supply and motherboard.
It is strongly recommended that you use a high quality power supply that meets ATX power
supply Specification 2.02 or later. It must also be SSI compliant.
