Desktop Board Features

Fan Headers

The function/operation of the fans is as follows:

The fans are on when the computer is in the ACPI S0 state.

The fans are off when the computer is in the ACPI S3, S4, or S5 state.

Each fan header is wired to a tachometer input of the hardware monitoring and control device.

All fan headers support closed-loop fan control that can adjust the fan speed or switch the fan on or off as needed.

All fan headers have a +12 V DC connection.

The Desktop Board has a 4-pin processor fan header, one 4-pin and two 3-pin chassis fan headers, and one 3-pin MCH fan header.

LAN Wake Capabilities

CAUTION

For LAN wake capabilities, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply.

LAN wakeup capabilities enable remote wake-up of the computer through a network. The LAN subsystem monitors network traffic and upon detecting a Magic Packet* frame, it asserts a wake-up signal that powers up the computer.

Instantly Available PC Technology

CAUTIONS

For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality.

Power supplies used with this Desktop Board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the Desktop Board may lose register settings stored in memory.

Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to- RAM) sleep state. While in the S3 sleep state, the computer will appear to be off. If the computer has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber. When signaled by a wake-up device or event, the computer quickly returns to its last known awake state.
