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.
