Abstract: In one embodiment, a method includes transmitting pulse power on two wire pairs, the pulse power comprising a plurality of high voltage pulses with the high voltage pulses on the wire pairs offset between the wire pairs to provide continuous power, performing low voltage fault detection on each of the wire pairs between the high voltage pulses, and transmitting data on at least one of the wire pairs during transmittal of the high voltage pulses. Data transmittal is suspended during the low voltage fault detection.

Abstract: In one embodiment, an apparatus includes a power supply operable to output power to a load along with at least one other power supply, a sensing component for identifying a load level, and a control component for switching the power supply from a full power mode to a power saving mode based on the identified load level. The power supply shares current with the other power supply at a lower current and generally the same voltage as the other power supply while in the power saving mode.

Abstract: A fault processing subsystem of an electronics assembly, senses an alarm state at an output of a first power distribution element of multiple power distribution elements arranged in a hierarchy in the electronics assembly. The first element is at a level of the hierarchy other than the top level, and the alarm state corresponds to an output of the first element being different than an expected output of that element. The fault processing subsystem commands, in response to the sensing the alarm state, the first element to disable via a control input to the first element. In response to the fault processing subsystem thereafter sensing an alarm state at the power output of the commanded element, the fault processing subsystem commands an element at the next higher level in the hierarchy from the first element to disable.

Abstract: Techniques are provided for detecting a fault across a pair of lines. Pulse power is applied across the pair of lines. The pulse power comprises alternating pulse on-time intervals and pulse off-time intervals. During a pulse off-time interval, a resistor is connected across the pair of lines and then disconnected when a voltage across the pair of lines reaches a first droop percentage in a first period of time. After disconnecting the resistor, it is determined whether the voltage across the pair of lines droops at least a second droop percentage within a second period of time that begins after the first period of time. Occurrence of a line-to-line fault across the pair of lines is determined when the voltage across the pair of lines droops by at least the second droop percentage or more within the second period of time.
