Product Description 1.12.2.2 Fan Headers The function/operation of the fan headers is as follows: • The fans are on when the board is in the S0 or S1 state • The fans are off when the board is off or 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 For information about The location of the fan headers The location of the fan headers and sensors for thermal monitoring Refer to Figure 11, page 41 Figure 6, page 26 1.12.2.3 LAN Wake Capabilities CAUTION For LAN wake capabilities, the +5 V standby line for 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 • Wake from CIR • Wake from S5 31

1.12.2.2
Fan Headers
The function/operation of the fan headers is as follows:
•
The fans are on when the board is in the S0 or S1 state
•
The fans are off when the board is off or 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
For information about
Refer to

LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the +5 V standby line for 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
•
Wake from CIR
•
Wake from S5
