Abstract: A power supply management system includes a power supply backplane, a plurality of power supply units connected to the power supply backplane, and a power controller chip. The power controller chip sends a plurality of power controlling signals to the power supply backplane. The power supply backplane transmits the plurality of power controlling signals to the plurality of power supply units, transition the plurality of power supply units into specific working states according to the plurality of power controlling signals, collect present working states of the plurality of power supply units, and sends the present working states of the plurality of power supply units to the power controller chip. A method for managing power supply units is also provided.

Abstract: An Inter-Integrated Circuit (I2C) bus structure includes a master device, a slave device, and an address setter connected to each other via I2C buses. The slave device has an original device address. The master device transmits an address set command to the address setter. The address setter changes the first device address of the slave device to a second device address in response to the address set command. An address management method is also provided.

Abstract: An Inter-Integrated Circuit (I2C) bus structure includes a master device and a slave device. The slave device is connected to the master device via an I2C bus and an interrupt line. When the master device receives an interrupt request from the slave device via the interrupt line, the master device determines that the slave device is available. When the master device has not received any interrupt request from the slave device via the interrupt line for a time period, the master device determines that the slave device is not available. A device availability query method is also provided.

Abstract: A connector assembly includes a first connector and a second connector. The first connector includes a plurality of first signal pins and a first hot-plugging detection pin. The second connector includes a plurality of second signal pins and a second hot-plugging detection pin. The first hot-plugging detection pin is configured to connect to the second hot-plugging detection pin when the plurality of first signal pins are connected to the plurality of second signal pins. The first hot-plugging detection pin is configured to disconnect from the second hot-plugging detection pin before the plurality of first signal pins are disconnected from the plurality of second signal pins.
