A system and method for reducing inrush current in an information handling system includes charging a pre-charge circuit with an elongated pin. The information handling system includes a midplane with at least one power source connector and multiple blade connectors able to connect to blade servers. Each blade connector has an elongated pin for supplying power to a blade server. Each blade server has a power connector for receiving the elongated pin and an integrated pre-charge circuit including a resistor and capacitor.

A redundant fan system includes an in-series configuration of adjustable speed fans. A speed controller coupled to the fan system includes a first fan operated at a constant operating speed and a second fan operated at an adjusted operating speed to maintain a speed differential between the first and second fan speeds. A sensing device is connected to the first and second fans and to the speed controller for maintaining the speed differential constant.
