摘要： A power device may include channels coupled to conductors in lines, where each one of the channels is coupled to a different one of the lines than the other channels and where the channels deliver direct current power signals over the conductors to the load devices. Each one of the load devices may be powered by a different one of the direct current power signals. The power device may include a power communicator that communicates with the load devices over the conductors that propagate the direct current power signals. The power communicator may determine a target power level for the load devices based on the communication over the conductors. The load device may adjust an amount of power in the direct current power signals in order to match the target power level.

摘要： In one embodiment, an apparatus includes a circuit coupled to a line, where the circuit may power a device, and where the power is transmitted to the device over the line as a pulse-width modulated signal. The circuit may set a duty cycle of the pulse-width modulated signal in order to transmit a determined power level to the device. The apparatus may vary a frequency of the pulse-width modulated signal to transmit data to the device while the duty cycle of the pulse-width modulated signal is fixed in order to continue to transmit the determined power level to the device. A variation in the frequency of the pulse-width modulated signal may be detectable by the device and represents at least a portion of the data.

摘要： A system for tracking rack-mount devices may be provided that may include a light fixture and a communication module. The light fixture may include one or more RFID readers and/or one or more antennas configured to read an RFID tag coupled to a rack-mount device. The rack-mount device may be mounted in any mounting position of a modular equipment rack. The communication module may cause a device identifier to be transmitted to a power device that powers the light fixture. The device identifier may identify the rack-mount device determined to be mounted in the modular equipment rack based on any of the RFID readers and/or any of the antennas reading the RFID tag.
