Claim Text:
1. A computer program product for controlling in rush current to a hot plug device, the computer program product comprising a computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to perform a method comprising: providing a series of turn on pulses to the gates of a plurality of turn on FETs on a hot plug device coupled to a direct current power source, wherein each pulse causes the plurality of FETs to pass current from the direct current power source to a subsystem of the hot plug device, and wherein each pulse has a duration that ends before the impedance of the turn on FETs falls below a safe operating region; and providing a steady turn on signal to the FETs in response to the output voltage from the FETs to a subsystem of the hot plug device exceeding a predetermined voltage threshold.
