Intel Desktop Board D945GBO 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.

1.13.2.1 Power

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.

1.13.2.2 Fan

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.

1.13.2.3 LAN 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.
