Fig. 1 assumes that a network card module 1021, a network card module 1022, a network card module 1023, and a network card module 1024 are configured on the I-th server board, a network card module of the same type as that of the I-th server board is configured on the L-th server board, the network card module 1021 on the I-th server board is correspondingly connected with the switching module 1011, the network card module 1022 is correspondingly connected with the switching module 1012, the network card module 1023 is correspondingly connected with the switching module 1013, and the network card module 1024 is correspondingly connected with the switching module 1014; the network card module 1021 on the L-th server board is correspondingly connected to the switching module 1011, the network card module 1022 is correspondingly connected to the switching module 1012, the network card module 1023 is correspondingly connected to the switching module 1013, and the network card module 1024 is correspondingly connected to the switching module 1014. Because each switching module can only run the service of one switching protocol, the switching protocol types supported by a single switching board are less, for example, the switching board 101 can only run the service of one switching protocol in the same time period.
An embodiment of the present invention provides a switch board 20, as shown in fig. 2, where the switch board 20 includes a bottom board 201 and at least 2 switch modules 202, where the switch modules 202 are located on the bottom board 201, and each switch module 202 is connected to a network card module of a server board through a backplane to run a service of one switch protocol, so that the switch board 20 can run services of at least 2 switch protocols. In particular, the switch module 202 may be fixedly disposed on the backplane 201 or connected to the backplane 201 by a snap or plug-in card.
Therefore, the exchange board comprises at least 2 exchange modules, each exchange module on the exchange board is connected with the network card module of the server board through the backboard, a service of one exchange protocol is operated, the types of the exchange protocols supported by a single exchange board are increased, and services of multiple exchange protocols can be operated simultaneously.
It should be noted that the type of the switching service may be an exchange protocol such as Ethernet (Ethernet), FCoE (fiber Channel over Ethernet), IB (InfiniBand), SAS (Serial Attached Small Computer System Interface), and the network card module also needs to configure a network card module with the same protocol type according to the exchange protocol type of the exchange module.

When signals are distinguished according to signal functions, the signal types comprise service signals and control management signals; when signals are distinguished according to signal electrical characteristics, the signal types include a high-speed signal and a low-speed signal. Specifically, the service signal may be a signal transmitted when the switch module is connected to the backplane through the backplane connector, and the control management signal may be a signal transmitted when the device management module is connected to the backplane through the backplane connector. In general, the high-speed signal may be the traffic signal for performing a switching function, and the low-speed signal may be the control management signal for performing a configuration management function.

The first switching module 2021 is connected to the first pin area M through a physical link a2 and the first network card module 4011 through a physical link a1, respectively, the physical links a2 and a1 establish connection between the first switching module 2021 and the first network card module 4011, the first switching module 2021 is connected to the first pin area M through a physical link e2 and the fifth network card module 4021 through a physical link e1, and the physical links e2 and e1 establish connection between the first switching module 2021 and the fifth network card module 4021; similarly, the second switch module 2022 is connected to the second pin area P through the physical link b2 and the second network card module 4012 through the physical link b1, the physical links b2 and b1 establish connection between the second switch module 2022 and the second network card module 4012, the second switch module 2022 is connected to the second pin area P through the physical link f2 and the sixth network card module 4022 through the physical link f1, and the physical links f2 and f1 establish connection between the second switch module 2022 and the sixth network card module 4022; the third switching module 2023 is connected to the third pin area Q through a physical link c2 and the third network card module 4013 through a physical link c1, respectively, the physical links c2 and c1 establish connection between the third switching module 2023 and the third network card module 4013, the third switching module 2023 is connected to the third pin area Q through a physical link g2 and the seventh network card module 4023 through a physical link g1, and the physical links g2 and g1 establish connection between the third switching module 2023 and the seventh network card module 4023; the fourth switching module 2024 is connected to the fourth pin area W through a physical link d2 and the fourth network card module 4014 through a physical link d1, the physical links d2 and d1 establish connection between the fourth switching module 2024 and the fourth network card module 4014, the fourth switching module 2024 is connected to the fourth pin area W through a physical link h2 and the eighth network card module 4024 through a physical link h1, and the physical links h2 and h1 establish connection between the fourth switching module 2024 and the eighth network card module 4024. Therefore, the pins of the backplane connector arranged in an array may be divided into n pin areas, where n is an integer greater than or equal to 2.
When the switching module is connected to the network card module, in this embodiment, it is assumed that the first switching module 2021, the first network card module 4011, and the fifth network card module 4021 run a GE Eth (Gigabit Ethernet) protocol service, and the switching protocol corresponding to the first pin region M is the GE Eth protocol, then the first switching module 2021 is connected to the first pin region M through the physical link a2 and the first network card module 4011 through the physical link a1 respectively to transmit a GE Eth protocol service signal, and the first switching module 2021 is connected to the first pin region M through the physical link e2 and the fifth network card module 4021 through the physical link e1 respectively to transmit a GE Eth protocol service signal.
