Abstract
Disclosed are a sensor for detecting when an infrastructure interface is physically coupled to network infrastructure, and infrastructure connection detection circuitry coupled to the sensor. The infrastructure connection detection circuitry provides a power management control signal as a function of a signal from the sensor.
Claims41
A system comprising:
- a sensor for detecting when an infrastructure interface is physically coupled to network infrastructure;
- and
- infrastructure connection detection circuitry coupled to said sensor, said infrastructure connection detection circuitry providing a power management control signal as a function of a signal from said sensor.
A system comprising:
- network interface circuitry providing information communication between an information processing system and a network;
- an infrastructure interface for coupling said network interface circuitry and said network for said information communication;
- at least one sensor for detecting when said infrastructure interface is physically coupled to a mating connector;
- and
- infrastructure connection detection circuitry coupled to said at least one sensor, said infrastructure connection detection circuitry providing a power management control signal as a function of a signal from said at least one sensor.
2 more elements
A method comprising:
- determining if an infrastructure interface is physically coupled to network infrastructure as a function of a sensor signal indicative of when an infrastructure interface is physically coupled to network infrastructure;
- and
- providing a power management control signal to alter a powered state of network interface circuitry when a condition of said infrastructure interface with respect to being physically coupled to said network infrastructure is determined to have changed.
A system comprising:
- means for detecting if an infrastructure interface is physically coupled to a mating connector;
- and
- means for providing a power management control signal when said means for detecting indicates said infrastructure interface has changed a condition with respect to being physically coupled to said network infrastructure.
