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.
