Abstract: A non-transitory computer readable storage medium having computer readable program code embodied therein, where the computer readable program code is adapted to, when executed by a processor, implement a method for managing a power supply system. The method includes identifying a number of power supplies included in the power supply system, and determining a first system mode for the power supply system. The method also includes determining a first operating order for the power supplies, and assigning a first ACTIVE ON threshold to each of the power supplies to obtain a number of first ACTIVE ON thresholds. The method further includes assigning a first ACTIVE STANDBY OFF threshold to each of the power supplies to obtain a number of first ACTIVE STANDBY OFF thresholds, where the power supply system provides electrical power to at least one computer system.

Abstract: A method for reducing latency using a charging module when activating a power supply unit (PSU) among a plurality of PSUs in a power supply system. The method includes: Receiving, by the PSU from a power input feed, input power; receiving, from a supply bus shared by the plurality of PSUs, a first controlled signal designating a status of the PSU as standby; disabling, in response to the first controlled signal, a switching regulator of the PSU; receiving, from a voltage rail of the supply bus, charge flowing through a resistor of the charging module to maintain a charge of an output capacitor of the switching regulator; receiving a second controlled signal designating the status of the PSU as active; enabling the switching regulator; outputting a voltage from the PSU through the charging module to the voltage rail; and charging the output capacitor using the PSU.

Abstract: A method for autonomous control by a power supply unit (PSU) among a number of current share PSUs in a power supply system. The method includes: Receiving input power from a power input feed; setting a mode of the PSU to ON; receiving a first controlled signal including a first number of IStar modes and thresholds; receiving a first activation signal activating IStar in the PSU; receiving a second controlled signal comprising a first voltage; determining that the first voltage is less than a first Active standby OFF threshold for an IStar mode of Active standby OFF; setting the IStar mode for the PSU to Active standby OFF; receiving a third controlled signal that includes a second voltage; determining that the second voltage is greater than a first Active ON threshold for an IStar mode of Active ON; and setting the IStar mode for the PSU to Active ON.

Abstract: An access device having an input port for connecting to an upstream section of a coaxial distribution cable and an output port for connecting to a downstream section of a coaxial distribution cable, and provides isolation of an RF communication signal from an AC power signal for access by subscriber network service equipment. The access device also includes power conditioning of the AC signal to provide a DC operating voltage over a separate output to operate the respective subscriber network service equipment.
