Intel Desktop Board D925XCV/D925XBC Technical Product Specification

Resume on Ring enables telephony devices to access the computer when it is in a power-managed state. The method used depends on the type of telephony device (external or internal).

NOTE

The use of Resume on Ring and Wake from USB technologies from an ACPI state requires an operating system that provides full ACPI support.

1.14.2.1Power Connector

ATX12V-compliant power supplies can turn off the system power through system control. When an ACPI-enabled system receives the correct command, the power supply removes all non-standby voltages.

When resuming from an AC power failure, the computer returns to the power state it was in before power was interrupted (on or off). The computer’s response can be set using the Last Power State feature in the BIOS Setup program’s Boot menu.

1.14.2.2Fan Connectors

The function/operation of the fan connectors is as follows:

The fans are on when the board is in the S0 or S1 state.

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

Each fan connector is wired to a fan tachometer input of the hardware monitoring and fan control ASIC

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

All fan connectors have a +12 V DC connection

1.14.2.3LAN Wake Capabilities

CAUTION

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

LAN wake capabilities enable remote wake-up of the computer through a network. The LAN network adapter monitors network traffic at the Media Independent Interface. Upon detecting a Magic Packet* frame, the LAN subsystem asserts a wake-up signal that powers up the computer.
