Introduction
Thank you for choosing the D-Link DFE-550TX - the value
leader among Fast Ethernet adapters for the PCI-Bus. This
introduction gives a general description of the newer
networking technologies found on the DFE-550TX.
ACPI Power Management
The DFE-550TX adapter complies with the Advanced
Configuration and Power Interface 1.0 (ACPI) specifications.
ACPI is a new open industry specification providing power
management support systems through hardware and
operating system cooperation. The DFE-550TX can reduce
power consumption by entering Sleep mode along with the
host computer. Although in Sleep mode, the network interface
card (NIC) will continue to monitor the LAN looking for wake-
up packets.
Wake On LAN
Wake On LAN (WOL) is an ACPI function allowing a powered
down (sleeping) computer to be powered ON from a remote
station. To use the WOL feature, the NIC must be WOL
capable and the motherboard of the PC must be ACPI
compliant.
While powered-down computers Sleep, WOL enabled NICs
monitor LAN traffic for valid Wake-up frames. When one is
received, the NIC will immediately wake-up and send a signal
to the motherboard to power ON the computer.
Some uses for the WOL feature include:
