Intel Desktop Board DQ35JO Technical Product Specification

1.14.2.2 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 fan header is 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.

1.14.2.3 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

⎯ By Ping

⎯ Magic Packet

• The onboard LAN subsystem

1.14.2.4 Intel

Management Engine Wake-on-LAN

The board supports waking the Intel

Management Engine over the network. This can

be enabled in the BIOS and allows Intel AMT to be remotely turned on through a wake

packet generated by a management console application or a ping. The client system

will be in a low power state until a management console alert requests Intel AMT

functionality.
