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. Power may be provided to the circuitry that generates the output signal and the interrupt signal.

A technique that is usable with a subterranean well includes communicating a slurry through a shunt flow path and operating a control device to isolate slurry from being communicated to an ancillary flow path. The system may include a shunt tube and a diverter. The shunt tube is adapted to communicate a slurry flow within the well to form a gravel pack. The diverter is located in a passageway of the shunt tube to divert at least part of the flow. A slurry may be communicated through the shunt flow path, and a control device may be operated to isolate the slurry from being communicated to the ancillary flow path.
