Fan Headers; Lan Wake Capabilities - Intel BLKDG33FBC Technical Product Specification

Intel Desktop Board DG33FB Technical Product Specification
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 processor and Auxiliary fan headers are wired to a fan tachometer input and
the Front and Rear fan headers share the tachometer input of the hardware
monitoring and fan 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.

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 Express WAKE# signal
• The PCI bus PME# signal for PCI 2.3 compliant LAN designs
• The onboard LAN subsystem
