Abstract: A power distribution unit (PDU) includes a housing configured to be mounted into or on a rack that has a plurality of shelf positions for a variety of computing equipment, networking equipment or data storage equipment. The PDU includes power inputs. The power inputs are configured to receive one or more of: alternating current (AC) power, high voltage direct current (DC) power, single-phase fault managed power, or multi-phase fault managed power. The PDU further includes at least one fault managed power module configured to be contained in the housing, the at least one fault managed power module including a power transmitter configured to generate single-phase or multi-phase fault managed power from the AC power and/or high voltage DC power. The PDU also includes a plurality of connectors on the housing and configured to provide cable connections to one or more of the plurality of shelf positions of the rack.

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: 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: Presented herein are techniques for connectors, apparatuses, and system with connectors for data and power. A connector at an end of the network cable can be configured to mate with a port in a device. The connector can include a set of data pins for connecting data wires in the network cable to the port. The connector can include a set of power pins for connecting power wires in the network cable to the port. The set of power pins can carry a higher electrical power than that carried by the set of data pins. A first spacing between adjacent power pins in the set of power pins has at least a minimum distance to reduce voltage breakdown between the adjacent power pins in the set of power pin.

Abstract: A system is provided that includes a power transmitter configured to provide power to a current loop, a power receiver configured to receive the power from the current loop. The power receiver is configured to, on a periodic basis, disconnect from the current loop to stop pulling power from the current loop for a period of time to enable a safety check to be performed by the power transmitter. The power transmitter is configured to: monitor current on the current loop; determine whether a current level on the current loop passes the safety check within a predetermined time interval since a determination that the current level was not within a safe range; and control connectivity of the power to the current loop depending on whether the safety check has or has not passed within the predetermined time interval.
