Abstract: Presented herein are techniques for preventing an electrical arc upon disconnect of a network cable. A method can include monitoring a network cable connected to a device for faults at a remote location from a connector of the network cable by observing conditions on the network cable of power applied to the network cable, wherein the network cable is for sending data and power. The method can further include detecting a fault on the network cable, wherein the fault was introduced intentionally at the connector prior to disconnecting the connector from the device. The method can further include terminating power at the remote location that is sent over the network cable to prevent an electrical arc upon disconnecting the connector from the device.

Abstract: In one embodiment, a method includes transmitting multi-phase pulse power from power sourcing equipment to a powered device in a data center, wherein the multi-phase pulse power comprises multiple phases of power delivered in a sequence of pulses defined by alternating low direct current voltage states and high direct current voltage states, and synchronizing the pulses at the power sourcing equipment with the pulses at the powered device.

Abstract: In one embodiment, a method includes applying Forward Error Correction (FEC) to data at power sourcing equipment, transmitting the data and pulse power over a wire pair to a powered device, identifying data transmitted during power transitions between a pulse power on time and a pulse power off time in the pulse power at the powered device, and applying FEC decoding to at least a portion of the data based on said identified power transitions.

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.
