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 Desktop Boards D865GBF and
D865GLC support LAN wake capabilities with ACPI in the following ways:
•
The PCI bus PME# signal for PCI 2.2 compliant LAN designs
•
The onboard LAN subsystem
