Abstract: A blade server system with a management bus and method for managing the same. The blade server system includes a connection board and a management module. The connection board is used for modular interconnection, including communication paths for conducting signals including a management bus signal group and a first bus signal group. The management module is used for management of the blade server system using signals including the management bus signal group and the first bus signal group. If a module is detected, the management module selects the detected module through the management bus and acquires module configuration information of the detected module through the first bus signal group. Distribution of power from a power source to the blade server system is determined according to system configuration information including the module configuration information of the module so that the power source is prevented from being overloaded.

Abstract: A method of controlling surge current in fan modules is applied in a blade server. The blade server includes a fan module having a first fan motor, a second fan motor, a first resistor/capacitor (RC) circuit and a second RC circuit. The blade server generates a control signal for controlling the first and the second fan motors. The first RC circuit receives and delays the control signal for a period of first time to output a first delay control signal for driving the first fan motor. The second RC circuit receives and delays the control signal for a period of second time to output a second delay control signal for driving the second fan motor. The first time is different from the second time and thus the first surge current in the first fan motor and the second surge current in the second fan motor are generated at different time.
