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
•

system that provides full ACPI support.
1.11.2.1 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.

1.11.2.2 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.
