Abstract: A data processing device includes an internal volume that is electromagnetic interference (EMI) isolated and a communication system, disposed in the internal volume, that: determines a first EMI state of at least one device of devices disposed in the internal volume; makes a determination that the first EMI state is an EMI emitting state; and disables communications by the communication system using a high-speed connection while allowing the communications using a low-speed connection.

Abstract: A physical layer transceiver (PHY) ability configuration system includes a peer computing device having a first communication subsystem that includes a first PHY device coupled to a first port. They system also includes a networking device having a second communication subsystem that includes a second PHY device and that is configured to operate in a plurality of modes and a second port that is coupled to the second PHY device. The networking device determines, in response to a cable coupling the first port and the second port while the second PHY device is configured to operate in a first mode of the plurality of modes, that a link is not detected at the second port. The networking device changes the first mode to a second mode of the plurality of modes, and detects the establishment of the link between the first port and the second port.
