Desktop Board Features

Power Connectors

The desktop board has two power connectors. See Figure 11 on page 36 for the location of the power connectors.

Fan Headers

The desktop board has two chassis fan headers and one processor fan header. See Figure 11 on page 36 for the location of the fan headers.

Chassis Intrusion

The board supports a chassis security feature that detects if the chassis cover has been removed. The security feature uses a mechanical switch (not included) on the chassis that can be connected to the chassis intrusion header on the desktop board. See Figure 11 on page 36 for the location of the chassis intrusion header.

Suspend to RAM (Instantly Available PC Technology)

CAUTION

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.

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. When signaled by a wake-up device or event, the system quickly returns to its last known awake state.

The desktop board’s standby power indicator, shown in Figure 2, is lit when there is standby power to the system. This includes the memory modules and PCI bus connectors, even when the computer appears to be off.

If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber.
