Fan Headers; Lan Wake Capabilities - Intel DZ87KLT-75K Specification

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 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
•

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
