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.
For information about

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
