For convenience of description, the fan control board 120_1 will be described as an example, and the other fan control boards 120_2~120_N are analogous.

Please refer to "FIG. 3" for a detailed schematic diagram of the fan control board 120_1 of the present disclosure. The fan control board 120_1 includes an address circuit 130_1 and a microcontroller 140_1. The address circuit 130_1 includes a plurality of first ports 131_1~131_N, a plurality of first resistors R1_1 RR1_N, a second resistor R2, and a second port 132.

The first connection ports 131_1~131_N are coupled to the connection ends 112 of the corresponding connection units 111 such that one of the first connection ports 131_1~131_N is coupled to the ground terminal 180. Taking the fan control board 120_1 as an example, the first connection port 131_1 of the address circuit 130_1 is coupled to the ground terminal 180.

The first ends of the first resistors R1_1~R1_N are respectively coupled to the first ports 131_1~131_N. For example, the first ends of the first resistors R1_1~R1_N are coupled to the first ports 131_1~131_N in a one-to-one manner. That is, the first end of the first resistor R1_1 is coupled to the first port 131_1, the first end of the first resistor R1_2 is coupled to the first port 131_2, ..., the first end of the first resistor R1_2 is coupled to the first end Connect 埠132_N. The first resistors R1_1 R R1_N each have different resistance values.

The first end of the second resistor R2 receives the operating voltage VCC, for example, P3V3, and the second end of the second resistor R2 is coupled to the second end of the first resistors R1_1 R R1_N and is used to generate an address signal. The second port 132 is coupled to the second end of the second resistor R2 for transmitting the address signal. In this embodiment, the second port 132 is a General Purpose Input Output (GPIO) port. The microcontroller 140_1 is coupled to the second port 132 for receiving the address signal to generate corresponding address information.

First, when the fan control board 120_1 is coupled to the power supply backplane 110_1, the first ports 131_1~131_N of the fan control board 120_1 are coupled one-to-one to the connection end 112 of the connection unit 111 of the power supply backplane 110_1. Since the first connection end 112 of the connection unit 111 of the power supply backplane 110_1 is coupled to the ground terminal 180, the operating voltage VCC is coupled to the ground terminal 180 via the second resistor R2 and the first resistor R1_1 to form a loop.

Then, after the loop is formed, the addressing circuit 130_1 divides the operating voltage VCC by using the second resistor R2 and the first resistor R1_1, and the second terminal of the second resistor R2 generates a corresponding addressing signal, for example, the addressing signal is First resistor R1_1 The pressure drop on it. Thereafter, the addressing circuit 130_1 transmits the address signal to the microcontroller 140_1 through the second port 132_1.

When the microcontroller 140_1 receives the address signal generated by the addressing circuit 130_1, for example, in a look-up manner, the address of the fan control board 120_1 located in the rack server 100 is defined according to the voltage drop corresponding to the address signal. To complete the addressing operation.

In addition, when the fan control board 120_2 is coupled to the power supply backplane 110_2, the first ports 131_1~131_N of the fan control board 120_2 are coupled to the connection end 112 of the connection unit 111 of the power supply backplane 110_2. Since the second connection end 112 of the connection unit 111 of the power supply backplane 110_2 is coupled to the ground terminal 180, the operating voltage VCC is coupled to the ground terminal 180 via the second resistor R2 and the first resistor R1_2 to form a loop.

Then, after the loop is formed, the addressing circuit 130_1 divides the operating voltage VCC by using the second resistor R2 and the first resistor R1_2, and the second terminal of the second resistor R2 generates a corresponding address signal, for example, the addressing signal is The voltage drop across the first resistor R1_2. Thereafter, the addressing circuit 130_2 transmits the address signal to the microcontroller 140_2 through the second port 132_1.

When the microcontroller 140_2 receives the address signal generated by the addressing circuit 130_2, for example, in a table lookup manner, the address of the fan control board 120_2 located in the rack server 100 is defined according to the voltage drop corresponding to the address signal. To complete the addressing operation. The address operation of the remaining fan control boards 120_3~120_N is analogous, so it is not here. Let me repeat.

As a result, the fan control boards 120_1~120_N have their addresses located in the rack server 100, and the 120_1~120_N addresses of the fan control boards are, for example, the address control operations are performed on the fan control boards 120_1~120_N. The Rack Management Controller (RMC) is provided to the rack server 100 for management and subsequent processing.

That is to say, when an error occurs in one of the fan control boards 120_1~120_N, the microcontroller of the fan control board that has an error does not provide the address information to the cabinet management controller, and the cabinet management controller can be To know which fan control board has an error, to increase the convenience of management and maintenance.

The rack server of the embodiment of the present disclosure, when a plurality of first ports are coupled to the power supply backplane, coupling one of the plurality of first ports to the ground, so that the operating voltage, The second resistor forms a loop with the first resistor corresponding to the first connection port coupled to the ground terminal to generate a corresponding address signal, and the microcontroller controls the fan control board in the rack server according to the address signal Perform the corresponding addressing operation. In one case, the convenience of use, management, and subsequent processing can be increased.
