Intel Desktop Board DP67BG Product Guide Fan Headers The function/operation of the fans is as follows: • The fans are on when the computer is in the ACPI S0 state. • The fans are off when the computer is in the ACPI S3, S4, or S5 state. • Each fan header is wired to a tachometer input of the hardware monitoring and control device. • 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. The Desktop Board has a 4-pin processor fan header and three 4-pin chassis fan headers. LAN Wake Capabilities CAUTION For LAN wake capabilities, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply. LAN wakeup capabilities enable remote wake-up of the computer through a network. The LAN subsystem monitors network traffic and upon detecting a Magic Packet* frame, it asserts a wake-up signal that powers up the computer. Instantly Available PC Technology CAUTIONS For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality. Power supplies used with this Desktop Board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the Desktop Board may lose register settings stored in memory. 22

The Desktop Board has a 4-pin processor fan header and three 4-pin chassis fan
headers.
LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the 5 V standby line for the power supply must be capable
of delivering adequate +5 V standby current.
Failure to provide adequate standby
current when using this feature can damage the power supply.
LAN wakeup capabilities enable remote wake-up of the computer through a network.
The LAN subsystem monitors network traffic and upon detecting a Magic Packet*
frame, it asserts a wake-up signal that powers up the computer.
Instantly Available PC Technology
CAUTIONS
For Instantly Available PC technology, the 5 V standby line for the power supply must
be capable of delivering adequate +5 V standby current.
Failure to provide adequate
standby current when using this feature can damage the power supply and/or effect
ACPI S3 sleep state functionality.
Power supplies used with this Desktop Board must be able to provide enough standby
current to support the standard Instantly Available (ACPI S3 sleep state) configuration.
If the standby current necessary to support multiple wake events from the PCI and/or
USB buses exceeds power supply capacity, the Desktop Board may lose register
settings stored in memory.
