[0019] In the embodiment, in order to realize that the control panel can support M-PESTI protocol and GPIO interface when the hanging ear plate as the server is connected with the mainboard of the server, the microcontroller unit 10 can be added in the control panel, and the microcontroller unit 10 is connected with the connector 11 through multiple general input / output port bus 15, modular peripheral edge band tunnel interface bus 16 and detection line 17. The detection line 17 can be connected with the DETECT pin in the microcontroller unit 10. If the above connection mode is adopted, when the microcontroller unit 10 detects that the mainboard is connected on the connector 11 and the level signal transmitted by the detection line 17 is a low level signal, it indicates that the mainboard connected with the connector 11 supports M-PESTI protocol, at this time, the DETECT pin can be short-circuited to ground, or the DETECT pin in the microcontroller unit 10 is short-circuited to ground based on the jump control set on the mainboard; when the microcontroller unit 10 detects that the mainboard is connected on the connector 11 and the level signal transmitted by the detection line 17 is a high level signal, it indicates that the mainboard connected with the connector 11 supports GPIO interface, at this time, the DETECT pin can be suspended, or the DETECT pin in the microcontroller unit 10 is suspended based on the jump control set on the mainboard.

[0020] More specifically, when the microcontroller unit 10 determines that the connected motherboard supports the M-PESTI protocol, the serial data transmitted by the modular peripheral sideband tunnel interface bus 16 can be decoded, and the decoded data can be used to control other components (such as the LED unit) on the control board; or the microcontroller unit 10 can be used to write data related to the key value into a specific register for the motherboard to read. When the microcontroller unit 10 determines that the connected motherboard supports the GPIO interface, the specified components (such as the LED unit or the key unit) are connected to the FPGA (Field-Programmable Gate Array) of the motherboard through the GPIO bus. As can be seen, through the single board of the control board described above, the docking of the server motherboard supporting the M-PESTI protocol and the GPIO interface is realized, that is, one card with multiple uses is realized.

[0021] The voltage conversion unit 12 is used to step down the received input voltage (such as 12V) to the working voltage (such as 3.3V) to supply power to the microcontroller unit 10 and other components. The connector 11 can be connected to the motherboard of the server through the connection cable, and the information interaction between the control board and the motherboard is realized through the connection cable, that is, for transmitting the interactive information between the motherboard and the control board, for example, the connection cable transmits the key information to the motherboard, and the motherboard transmits the information for controlling the LED unit to turn on or off to the control board.

The multiplexing switch 102 is used to determine whether to turn on the module peripheral sideband tunnel interface bus 16 or the multiple general input / output port buses 15 based on the level signal transmitted by the detection line 17. Specifically, when the microcontroller unit 10 determines that the level signal transmitted by the detection line 17 is a low-level signal, the multiplexing switch 102 is controlled to turn on the module peripheral sideband tunnel interface bus 16; when the microcontroller unit 10 determines that the level signal transmitted by the detection line 17 is a high-level signal, the multiplexing switch 102 is controlled to turn on the multiple general input / output port buses 15.

[0029] In the embodiment, the second light emitting diode LED2 is different from other light emitting diodes in that it directly receives the input voltage and is connected with the microcontroller unit 10 through the field effect transistor FET. Moreover, the third light emitting diode LED3 and the fourth light emitting diode LED4 can constitute a light emitting diode group. The first light emitting diode LED1 is used to indicate the server power state, for example, when the first light emitting diode LED1 emits light, it indicates that the server power is normal, and when the first light emitting diode LED1 is off, it indicates that the server power is abnormal. The second light emitting diode LED2 is used to indicate the server positioning state, for example, when the second light emitting diode LED2 emits light, it indicates that the server positioning state is normal, and when the second light emitting diode LED2 is off, it indicates that the server positioning state is abnormal. The light emitting diode group composed of the third light emitting diode LED3 and the fourth light emitting diode LED4 is used to indicate the server health state, for example, when the light emitting diode group emits green light, it indicates that the server is in a healthy state, and when the light emitting diode group emits amber light, it indicates that the server is in an abnormal state. The fifth light emitting diode LED5 is used to indicate the server hard disk reading state, for example, when the fifth light emitting diode LED5 emits light, it indicates that the server hard disk is being read, and when the fifth light emitting diode LED5 is off, it indicates that the server hard disk is not being read.
