Intel Desktop Board DG965WH Technical Product Specification LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. 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. 1.10.2.1 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. For information about The location of the main power connector The signal names of the main power connector Refer to Figure 16, page 52 Table 27, page 56 1.10.2.2 Fan Headers The function/operation of the fan headers is as follows: • The fans are on when the board is in the S0 state. • The fans are off when the board is off or in the S3, S4, or S5 state. • Each fan header is wired to a fan tachometer input of the hardware monitoring and fan 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.

LAN wake capabilities and Instantly Available PC technology require power from the
+5 V standby line.
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).

The use of Resume on Ring and Wake from USB technologies from an ACPI state
requires an operating system that provides full ACPI support.
1.10.2.1
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.

1.10.2.2
Fan Headers
The function/operation of the fan headers is as follows:
•
The fans are on when the board is in the S0 state.
•
The fans are off when the board is off or in the S3, S4, or S5 state.
•
Each fan header is wired to a fan tachometer input of the hardware monitoring and
fan 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.
