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 in the S3, S4, or S5 state
•
Each fan header is wired to a fan tachometer input of the hardware monitoring and
fan control ASIC
•
All fan headers support closed-loop fan control that can adjust the fan speed or
switch the fan on or off as needed
•
All fan headers have a +12 V DC connection
•
4-pin fan headers are controlled by Pulse Width Modulation
•
The front fan and rear fan headers also support linear fan control on 3-wire fans

LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line for the power supply must be capable
of providing ad5 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 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.
