2.13.2 Hardware Support
The board provides several power management hardware features, including:
Power connector
Fan header
LAN wake capabilities
Instantly Available PC technology
Wake from USB
Wake from PS/2 devices
Power Management Event signal (PME#) wake-up support
WAKE# signal wake-up support
+5V Standby Power Indicator LED
LAN wake capabilities and Instantly Available PC technology require power from the
+5 V standby line.
NOTE
The use of Wake from USB technologies from an ACPI state requires an operating
system that provides full ACPI support.
2.13.2.1 Fan Header
The function/operation of the fan header is as follows:
The fan is on when the board is in the S0 state.
The fan is off when the board is off or in the S3, S4, or S5 state.
The system fan header supports closed-loop fan control that can adjust the fan
speed and is wired to a fan tachometer input.
The fan header supports +12 V, 3-wire fans at 1 A maximum.

2.13.2.2 LAN Wake Capabilities
LAN wake capabilities enable remote wake-up of the computer through a network. The
LAN subsystem network adapter monitors network traffic at the Media Independent
Interface. The board supports LAN wake capabilities with ACPI in the following ways:
By Ping
By Magic Packet
Upon detecting the configured wake packet type, the LAN subsystem asserts a wake-
up signal that powers up the computer.
