Abstract
In one embodiment, a single electrical power supply is used to interchangeably power either a single motherboard or dual motherboards. Switchable output power and individual sequencing may be provided to each motherboard using FETs, such that the power supply may respond to the sequencing of each motherboard as if it were dedicated to that motherboard. In a two motherboard system, power to the first motherboard is reduced by removing some output voltages from the first motherboard. Fault circuitry may also be provided so that a power related fault on one domain does not affect operation of the other motherboard.
