Intel Desktop Board DQ43AP Technical Product Specification
1.14.2.2
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.
•
The processor fan header is wired to a fan tachometer input. The front and rear fan
headers each have independent tachometer input to the hardware monitoring and
fan control device. 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.

LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line from 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 subsystem PCI bus 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. Depending on the LAN
implementation, the board supports LAN wake capabilities with ACPI in the following
ways:
•
The PCI Express WAKE# signal
•
The PCI bus PME# signal for PCI 2.3 compliant LAN designs
⎯ By Ping
⎯ Magic Packet
•
The onboard LAN subsystem
