Intel Desktop Board D865GSA 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.
1.10.2.1 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.

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.
