Abstract: In the system, a buffer and a multiplexer are electrically connected to an I2C interface and a control interface of a PCH. A plurality of memory are electrically connected to the buffer and corresponding to a first I2C address respectively. A plurality of card slots are electrically connected to the multiplexer for connecting to a function card so that the function card is corresponding to a second I2C address. When the first I2C address is distinct to the second I2C address, the PCH triggers the multiplexer to be enabled through the control interface to have the function card electrically connected to the PCH through the I2C interface. When the first I2C address is the same as the second I2C address, the PCH triggers the multiplexer or the buffer to be disabled through the control interface to have the function card or the memories electrically connected to the PCH through the I2C interface.

The first sliding tray module includes a first belt unit, a baffle is disposed on one end of the first belt unit. The switch module includes an elastic piece and a switch. The first sliding tray module and/or the second sliding tray module slide/slides in or out to make the elastic piece and the baffle touched or untouched. The switch generates a switch signal according to whether the elastic piece and the baffle being touched or untouched. While the elastic piece and the baffle are untouched, the main board is configured to generate a detecting time according to the switch signal, and while the detecting time is longer than a safe time, the main board generates a warning signal through the electronic apparatus.

Abstract: A server includes a control module, a power-supply unit, a storage unit and a switch unit. The control module is electrically connected to a storage device. When the server is powered on, a first power is transmitted to from the power-supply unit to the storage unit and the switch unit, and received by the switch unit to generate a third power. When the server is powered off, the storage unit is triggered to transmit a second power to the switch to make the switch transmit the third power. The control module is provided to control a transmission information between the storage device and a buffer of the control module. When the server is powered on again, the control module continually works according to the transmission information stored in the buffer.

Abstract: A server for selectively switching management network is disclosed in the present invention. In the server, a baseboard management controller (BMC) is provided to send a connection signal in a dedicated management network connection status. The BMC is also provided to send a trigger signal and the connection signal in a triggering event. A dedicated network connection controller of a dedicated network connection module receives the connection signal in the dedicated management network connection status to make the BMC connect to a client through a dedicated network connection port of the dedicated network connection module. In the triggering event, a programmable logic unit receives the connection signal to transmit a switch signal to a switch of a general network connection module. When the switch receives the switch signal, the switch is turned on to make a general network connection controller of the general network connection module receive the connection signal.

Abstract: A server with a power source protection system and a method thereof are provided herein, in which the server includes a power-controlling device and a hard disk drive connector. The power-controlling device includes an input unit that receives an input voltage, an output unit that outputs a load voltage, a switching unit coupled between the input unit and the output unit, and a processor coupled to the switching unit.

The hard disk drive connector coupled to the output unit receives the load voltage. When the bad current exceeds a predetermined current value, the processor turns off the switching unit for a cut-off period and retries to turn on the switching unit after the cut-off period so as to output the load voltage.
