Intel Desktop Board D5400XS 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 two 4-pin processor fan headers, one 4-pin and two 3-pin chassis fan headers, one 3-pin MCH fan header, and one 3-pin DIMM cooling fan header. 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. 22

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.
