Intel Desktop Board DG41TX Product Guide Hardware Support Power Connectors ATX12V-compliant power supplies can turn off the computer power through system control. When an ACPI-enabled computer 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 (either on or off). The computer's response can be set by using the Last Power State feature in the BIOS Setup program's Boot menu. The Desktop Board has two power connectors. See Figure 24 on page 53 for the location of the power connectors. Fan Headers The function/operation of the fans is as follows: • The fans are on when the computer is in the ACPI S0 state. • The fans are off when the computer is in the ACPI S3, S4, or S5 state. • All fan headers support closed-loop fan control that can adjust the fan speed according to thermal conditions. • All fan headers have a +12 V DC connection. • The system fan headers support auto-detection for 4-pin and 3-pin chassis fans. If a 4-pin chassis is detected, PWM control is used. If a 3-pin fan is detected, linear voltage control is used. The Desktop Board has a 4-pin processor fan header and two 4-pin chassis fan headers. LAN Wake Capabilities CAUTION For LAN wake capabilities, 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. LAN wakeup capabilities enable remote wake-up of the computer through a network. The LAN subsystem monitors network traffic and upon detecting a Magic Packet* frame, it asserts a wake-up signal that powers up the computer. 24
