1.13.2.2 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 chassis fan header supports closed-loop fan control that can adjust the fan
speed and is wired to a fan tachometer input.
All fan headers have a +12 V DC connection.

1.13.2.3 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 bus PME# signal for PCI 2.3 compliant LAN designs
By Ping
Magic Packet
The onboard LAN subsystem
