Furthermore, according to the needs of different customers, the resistance slots at different positions in the first stacked disk part and the second stacked disk part of the configurable circuit board can be selectively configured, thus realizing different configuration modes in the same configuration circuit.

The present invention adopts a form of single hardware compatibility design, which can meet the needs of different customers while reducing production and R & D costs and improving production efficiency.

[0049] Figure 2FIG. 2 is the second structural schematic diagram of the configurable circuit provided by the present invention. A first resistor is soldered in the first stacked disk portion to connect the MDI interface of the network card chip to the MDI interface of the switch chip, so that the second resistor slot in the first stacked disk portion is in an idle state, disconnecting it from the second stacked disk portion related to the MDI signal, and there will be no residual branches in the traces, and the residual branches will affect the signal, thereby ensuring the signal path.

[0050] Before, after or at the same time as soldering the first resistor in the first stacked disk portion, a second resistor is soldered in the second stacked disk portion to connect the management network port to the MDI interface of the switch chip, so that the fourth resistor slot in the second stacked disk portion is in an idle state, disconnecting it from the first stacked disk portion related to the MDI signal, and there will be no residual branches in the traces, thereby ensuring the signal path.

[0051] Optionally, as Figure 2 shown, as the design circuit for configuring the BMC, the BMC 11 is connected to the switch chip 12 through the media independent interface RGMII. The switch chip 12 is connected to the first connection end of the first stacked disk portion through the media interface MDI. The first overlapping end 212 of the first stacked disk portion is connected to the network card chip 42 through the media interface MDI. The network card chip 42 is connected to the CPU through the Peripheral Component Interconnect Express (PCIe). The switch chip 12 is also connected to the third connection end of the second stacked disk portion through the media interface MDI. The second overlapping end 312 of the second stacked disk portion is connected to the management network port 5 through the media interface MDI.

[0052] Figure 3 FIG. 3 is the third structural schematic diagram of the configurable circuit provided by the present invention. A second resistor is soldered in the first stacked disk portion to connect the MDI interface of the network card chip 42 to the first overlapping end 212 of the first stacked disk portion, so that the first resistor slot in the first stacked disk portion is in an idle state, disconnecting it from the switch chip 12 related to the MDI signal, and there will be no residual branches in the traces, and the residual branches will affect the signal, thereby ensuring the signal path.

[0053] Before, after or at the same time as soldering the first resistor in the first stacked disk portion, a fourth resistor is soldered in the second stacked disk portion to connect the management network port 5 to the second overlapping end of the second stacked disk portion, so that the third resistor slot in the second stacked disk portion is in an idle state, disconnecting it from the switch chip 12 related to the MDI signal, and there will be no residual branches in the traces, thereby ensuring the signal path. At the same time, the first connection end 211 of the first stacked disk portion is connected to the fourth connection end 321 of the second stacked disk portion through the MDI interface.

[0054] Optionally, as Figure 3As shown in the figure, for the designed circuit without BMC configuration, the CPU 41 is connected to the network card chip 42 through the computer expansion bus standard PCIe. The network card chip 42 is connected to the first overlapping end 212 through the media interface MDI. The second connection end 221 of the first stacked disk part is connected to the fourth connection end 321 of the second stacked disk part through the media interface MDI. The second overlapping end 312 of the second stacked disk part is connected to the management network port 5 through the media interface MDI.

[0055] Figure 4 It is a schematic flowchart of the configuration method of the configurable circuit provided by the present invention. The present invention provides a configuration method for a configurable circuit, including:

[0056] Determine the configuration mode according to the configuration requirements. The configuration mode includes the BMC configuration mode or the non - BMC configuration mode;

[0057] In the case where the configuration mode is the BMC configuration mode, configure the first resistor to the first resistor slot and configure the third resistor to the third resistor slot;

[0058] In the case where the configuration mode is the non - BMC configuration mode, configure the second resistor to the second resistor slot and configure the fourth resistor to the fourth resistor slot.

[0059] In step 101, the configuration requirements are determined according to the user's needs. The user can choose to select a BMC on the configurable circuit according to actual needs. That is, the configuration mode includes the BMC configuration mode or the non - BMC configuration mode. For different configuration modes, the resistor welding schemes on the first stacked disk part and the second stacked disk part will also be different. The BMC is used for data forwarding among the BMC, the CPU, and the management network port.

[0060] In step 102, in the case where the configuration mode is the BMC configuration mode, configure the first resistor to the first resistor slot and configure the third resistor to the third resistor slot. As Figure 2 shown, due to the co - lay (Compatible Layout) design in the printed circuit board (PCB), that is, the design method where two devices share some pads. When configuring the first resistor to the first resistor slot, it is impossible to configure the second resistor to the second resistor slot. When configuring the third resistor to the third resistor slot, it is impossible to configure the fourth resistor to the fourth resistor slot. Thus, a path is formed among the BMC 11, the switching chip 12, the network card chip 42, and the CPU, and a path is formed among the BMC 11, the switching chip 12, and the management network port 5.

[0061] In step 103, when the configuration mode is the non - BMC - configuration mode, configure the second resistor to the second resistor slot and configure the fourth resistor to the fourth resistor slot. As Figure 3 shown, when configuring the second resistor to the second resistor slot, it is impossible to configure the first resistor to the first resistor slot. When configuring the fourth resistor to the fourth resistor slot, it is impossible to configure the third resistor to the third resistor slot, thereby enabling the CPU 41, the network card chip 42, and the management network port 5 to form a path.

[0062] Optionally, configuring the first resistor to the first resistor slot and configuring the third resistor to the third resistor slot includes:

[0063] Weld the first resistor to the first resistor slot to form a first path where the baseboard management controller BMC configuration part is connected to the network card chip configuration part via the first stacked disk part;

[0064] Weld the third resistor to the third resistor slot to form a second path where the baseboard management controller BMC configuration part is connected to the management network port via the second stacked disk part.

[0065] In the present invention, it is necessary to weld the first resistor to the first resistor slot and weld the third resistor to the third resistor slot simultaneously to complete the BMC mode configuration. In the baseboard management controller BMC configuration part, the design method of the BMC and the switch chip circuit is actually adopted. A switch chip with at least 1 RGMII interface and 2 MDI interfaces needs to be selected. Optionally, the switch chip can have two MDI interfaces with two 10 / 100 / 1000M rate Ethernet Transceivers, two gigabit interfaces, and three RGMII interfaces.

[0066] The RGMII interface of the BMC is connected to the RGMII interface of the switch chip through PCB traces. One MDI interface of the switch chip is connected to the first stacked disk part, and the other MDI interface of the switch chip is connected to the second stacked disk part.

[0067] The network card chip configuration part actually adopts the design method of the CPU and the network card circuit. A network card chip of the PCIe - to - MDI interface type needs to be selected. The PCIE interface of the CPU is connected to the PCIe interface of the network card chip through PCB traces, and the MDI signal of the network card chip is connected to the first stacked disk part through PCB traces.

[0068] Optionally, the management network port is an RJ45 connector, supporting 10 / 100 / 1000M rate, and is connected to the second stacked disk part through PCB traces internally and can be connected to a debugging computer or a management switch through a network cable externally.

[0069] Optionally, configuring the second resistor to the second resistor slot and configuring the fourth resistor to the fourth resistor slot includes:

[0070] Soldering the second resistor to the second resistor slot and soldering the fourth resistor to the fourth resistor slot to form a third path for the network card chip configuration unit via the first stacked disk unit, the second stacked disk unit, and the management network port.

[0071] Optionally, the first resistor, the second resistor, the third resistor, and the fourth resistor are resistors with resistance values less than a preset value. The preset value can be 1 ohm, 0.2 ohm, etc. In an optional embodiment, the first resistor, the second resistor, the third resistor, and the fourth resistor all have a resistance value of 0 ohm. In such an embodiment, the first stacked disk unit is a 0-ohm resistor stacked disk design. Among them, the pins of the first resistor slot and the second resistor slot are stacked together and connected to the MDI interface of the network card through PCB traces. Another pin of the first resistor slot is connected to the MDI interface of the switching chip through PCB traces. Another pin of the second resistor slot is connected to the second stacked disk unit through PCB traces. Since the MDI signal is a signal of four differential pair types, multiple 0-ohm resistors can also be used, and the same design method is used for each signal line. The PCB is a support for electronic components and a carrier for the electrical interconnection of electronic components.

[0072] The first stacked disk unit is also a 0-ohm resistor stacked disk design. Among them, the pins of the third resistor slot and the fourth resistor slot are stacked together and connected to the management network port through PCB traces. Another pin of the third resistor slot is connected to the MDI interface of the switching chip through PCB traces. Another pin of the fourth resistor slot is connected to the first stacked disk unit through PCB traces. Since the MDI signal is a signal of four differential pair types, multiple 0-ohm resistors are used, and the same design method is used for each signal line.

[0073] The present invention provides a configurable circuit, a configuration method, a configurable circuit board, and a switch. By using the connection relationships between the first stacked disk unit and the second stacked disk unit and the substrate management controller BMC configuration unit, the network card chip configuration unit, and the management network port to deploy the configurable circuit, it is possible to selectively configure the resistor slots at different positions in the first stacked disk unit and the second stacked disk unit in the configurable circuit board according to the needs of different customers, thereby realizing different configuration modes in the same configuration circuit. The configuration modes include configuring the BMC mode or not configuring the BMC mode. The present invention adopts a form of single hardware compatible design, which can meet the needs of different customers while reducing production and R & D costs and improving production efficiency.
