ABSTRACT:
A system for controlling power application to an electronic component during a hotswap operation. A chassis contains a plurality of slots for interfacing with electronic components, each slot having an associated timing device. The electronic component contains a delay mechanism, such that when the electronic component interfaces with a slot in the chassis, the delay and timing mechanisms interact to create a slot timing circuit. The slot timing circuit interfaces to a ramp-up switching circuitry to produce a controlled application of power to remaining circuitry of the electronic component. The timing mechanism may be a resistor and the delay mechanism may be a capacitor, such that an RC circuit is formed which controls, in a time delayed fashion, a switching mechanism which in turn controls ramp-up of power application to the electronic component. Furthermore, each timing mechanism of each slot in the chassis may have a different timing value, such that power application to multiple electronic components, inserted simultaneously into the chassis, may have power applied in a staggered fashion, to prevent inrush and surge currents to the power supply. Still further, each switching mechanism of an electronic component may have an associated power control circuit, which when activated by the slot timing circuit, controls ramp-up of power application to remaining circuitry of the electronic component in a controlled fashion.
