Server

A method for managing two baseboard management controllers comprises connecting to a first baseboard management controller, sending an instruction to the first baseboard management controller, determining whether the instruction comprises a bridge parameter, when the instruction comprises the bridge parameter, sending the instruction to a second baseboard management controller through a bus, generating a response signal by the second baseboard management controller, and receiving the response signal by the first baseboard management controller and sending the response signal to an administration interface; otherwise, executing a corresponding operation according to the instruction by the first baseboard management controller and sending an operation result to the administration interface.

Server system and method for managing two baseboard management controllers

A computer system including a first and second main boards, a judgment unit, a power supply, a first switch and second switch is provided. The judgment unit receives a first and second power start signals from the first and second main boards, and outputs a total power start signal. The power supply outputs a power reply signal according to the total power start signal. The first and second switches determine whether to output a power good signal individually according to the first and second power start signals. When one of the first and second power start signals is available, the total power start signal and the power reply signal are available, and the power supply outputs an operating voltage. When the first and second power start signals are unavailable, the total power start signal and the power reply signal are unavailable, and the power supply stops outputting the operating voltage.

Computer system

A computer system including a power supply and N main boards is provided, herein N is an integer greater than 1. The power supply generates a main power and a standby power. The N main boards respectively correspond to one standby voltage. The 1to the (N&#x2212;1)main boards respectively generate the corresponding standby voltage by the main power in a power-on state, and respectively generate the corresponding standby voltage by the standby power in a power-off state. The Nmain board generates the corresponding standby voltage by the main power in the power-on and power-off state.

A computer system including a power supply, a plurality of mainboards, and a power controller is provided. Each of the mainboards corresponds to a standby voltage, respectively. The power supply generates a standby power, and generates a main power according to a power enabling signal. The power controller is coupled between the power supply and the mainboards, for generating the power enabling signal and a control signal according to whether an amount of the mainboards is greater than a predetermined value, and selectively outputting the control signal to at least one of the mainboards. When the mainboards receive the control signal, regardless being in a booting state or a non-booting state, the mainboards receive the main power and converts the main power into a standby voltage corresponding thereto. When failing to receive the control signal, the mainboards convert the standby power into the standby voltage corresponding thereto.

A sever including a chassis, at least one first tray, at least one second tray, a power supply module, multiple input/output interface circuit boards, and multiple mother boards is provided. The first and second trays are slidably disposed in the chassis, and the first and second trays can be drawn out of the chassis in opposite directions. The power supply module is disposed on a bottom plate of the chassis. The input/output interface circuit boards are disposed on the first tray, respectively. The power supply module is located between two input/output interface circuit boards. Each input/output interface circuit board has multiple input/output interfaces. The mother boards are disposed on the second trays, respectively. The input/output interface circuit boards and the power supply module are correspondingly electrically connected to the mother boards.

An apparatus for resolving conflicts happened between two I2C slave devices with the same addressed address is provided. The apparatus is composed by all cheap electronic devices, so as to achieve a purpose of lowering a cost for design. In addition, in the apparatus for resolving conflicts happened between two I2C slave devices with the same addressed address of the invention, all the IC slave devices are addressed by an IC master device to perform the data transmission subsequently before a basic input/output system (BIOS) completes a power-on self-test (POST), but all the IC slave devices are addressed by a system chip (for example, a baseboard management controller (BMC)) to perform the data transmission subsequently after the BIOS completes the POST. Therefore, the purpose of performing the data transmission for all the IC slave devices on real time is achieved.
