Patent number: 8195247Abstract: Certain embodiments of a cable sense mode for intelligent power saving in the absence of a link pulse may include detecting an energy level of an Ethernet link. The Ethernet link may couple a network adapter chip to a network. The power supplied to the network adapter chip may be adjusted based on the detected energy level. Power may be supplied to the network adapter chip if the detected energy level of the Ethernet link is greater than or equal to a particular energy level. Power may be reduced to the network adapter chip if the detected energy level of the Ethernet link is less than a particular energy level. An output signal and/or an interrupt signal may be generated that indicates a change in the detected energy level of the Ethernet link.
