Abstract
A computer system includes a power supply coupled to a control logic, the power supply including a power_good output signal and Power output lines. The power_good signal notifies the control logic when the Power output lines have stabilized. The computer system also includes a plurality of voltage regulator modules (“VRM”) coupled to the control logic, wherein each VRM receives a power good signal from the control logic. A plurality of processors is also present in the computer system, each of the processors coupled to a VRM. Each of the VRMs transmits voltage to a processor to power-on the processor. Each VRM also transmits to its processor and to the control logic a voltage regulator module power good (“VRMP_G”) signal. The control logic includes means to control the sequential power-on of the processors so as to reduce the current sourcing requirements of the power supply and eliminate power supply surges.
