Abstract: 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.

Abstract: A modular information handling system includes a KVM management card. The KVM management card manages KVM communication with associated blade servers and allows access to KVM signals from each of the associated blade server through a VGA connector, a first PS2 connector and a second PS2 connector.

Abstract: A system for externally controlling keyboard video monitor (KVM) functions within a server blade architecture. The system includes an external KVM controller and a server blade chassis coupled to the external KVM controller. The server blade chassis includes a server blade and a management module coupled to the server blade. The management module includes an integrated KVM module. The integrated KVM module detects whether the external KVM controller is coupled to the server blade chassis. When the external KVM controller is coupled to the server blade chassis, the integrated KVM module functions as a relay agent between the external KVM controller and the server blade. When the external KVM controller is not coupled to the server blade chassis, the integrated KVM module functions as a master KVM controller for the server blade chassis.

Abstract: 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.
