[0037] With the continuous development of computer technology, servers have become an indispensable part of modern enterprises. The hardware modules inside the server are mainly composed of a mainboard, a processor, a memory, a hard disk, a network card and a power supply, etc. With the continuous iteration and update of servers, the functions supported by the servers are becoming more and more complex, so the computing performance requirements of the servers are getting higher and higher, and the computing performance of single-node servers has gradually failed to meet the demand for huge computing power, so dual-node servers have emerged.

[0038] The traditional single-node server refers to a single node composed of one server, which is used to carry and run application programs or provide specific services. The single-node server has only one mainboard inside the case, and all hardware configurations inside the server are connected to this mainboard, including power board, network board, fan board, hard disk backboard and riser card slot (RISER) and other sub-card configurations. The configuration and management of the single-node server are relatively simple, the cost is low, it is easy to deploy, and since there is only one node, the performance is relatively consistent, and there is no difference between nodes. However, the single-node server has no redundancy mechanism, and once the server fails, the entire service will be immediately interrupted, and the scalability of the single-node server will be limited. When the load increases, a single node may not be able to handle all requests, and the expansion capability is limited. In addition, the computing performance and resources of the single-node server are limited, and the central processing unit (CPU), memory and storage resources of a single node are limited, which cannot meet large-scale demand. The development of dual-node servers effectively solves various problems of single-node servers.

[0039] The dual-node server generally refers to a cluster system composed of two server nodes. The dual-node server has two mainboards in the chassis, and the two mainboards correspond to the two nodes. In the dual-node server, each node has its own separate hardware configuration and common hardware modules. For example, the power board in the dual-node server can supply power to node 0 or node 1, so that the power supply of the two nodes in the dual-node server can be met by using one power board, greatly saving the space inside the server. In addition to the power supply requirement, the network connection problem of the dual-node server also needs to be focused on. The network connection problem of the single-node server can be solved by using a network pass-through board. The Slimline connector on the network pass-through board is connected to the Slimline connector on the mainboard through a cable, and then the network cable is connected to the RJ45 connector on the network pass-through board to realize the network connection of the single-node server. This network pass-through board is suitable for single-node servers. If the network pass-through board is applied to the dual-node server, each node needs a network pass-through board, and the dual-node server needs two identical network pass-through boards to ensure normal network connection. Although this network connection method can realize the normal connection of the two nodes, it will occupy more chassis front window space resources and network port resources.

[0040] Referring to Figure 1 , Figure 1 is a structural diagram of a network pass-through board. The network pass-through board is composed of an RJ45 connector, a Slimline connector and a chip on the board. The chip on the network pass-through board mainly includes a temperature sensor and a memory. The temperature sensor is mainly used to monitor the temperature of the network pass-through board, and the memory is mainly used to store the relevant information of the network pass-through board.

[0041] Referring to Figure 2 , Figure 2A network connection topology diagram of a single-node server in the related art is shown in FIG. 1. As shown in the diagram, a Slimline connector at the end of a mainboard and a Slimline connector at the end of a network pass-through board are connected by a cable, so that the mainboard and the network pass-through board are in communication. Network signals (MDI) between a physical layer interface (PHY) chip on the mainboard and an RJ45 connector on the network pass-through board are directly connected, and devices such as electrostatic protection (ESD) devices can be connected in between to protect the quality of the network signals. The LINK_ACT signal and the lighting signal (such as the 100M / 1000M lighting signal) are controlled by the physical layer interface chip on the mainboard, and when the RJ45 connector on the network pass-through board is connected to an external network port or switch through a network cable, the network port light on the RJ45 connector will indicate the status of the network connection under the control of the physical layer interface chip.

[0042] When the network port light is normally lit, it means that the network connection function of the single-node server is normal. As can be intuitively felt from the above diagram, this network connection method is very suitable for single-node servers, the principle is very simple, and the implementation of network connection is very convenient, which not only ensures the convenience of network connection of the single-node server, but also guarantees the stability of network connection of the single-node server.

[0043] In the actual server field, dual-node servers are becoming more and more common. Both nodes in the dual-node server need network connection, and a network pass-through board can only realize the network connection function of one node, so it is obvious that there are certain disadvantages in using a network pass-through board in a dual-node server.

[0044] Referring to Figure 3 , Figure 3 A network connection topology diagram of a dual-node server in the related art is shown in FIG. 2. As shown in the diagram, if a network pass-through board is used to realize the network connection of the dual-node server, node 0 and node 1 (i.e., mainboard 0 and mainboard 1) both need to be connected to a separate network pass-through board, and each network pass-through board needs to be connected to a different RJ45 connector by a separate network cable. Although this method can realize the network connection function of the two nodes of the dual-node server, using two network pass-through boards not only makes the internal space of the dual-node server more cramped, but also occupies more space of the front window of the server by the two RJ45 connectors, wasting network port resources.

[0045] Therefore, the local area network switching board provided in the present application saves the internal space of the dual-node server and the external network port resources.

[0062] The first Slimline connector 3 is used for forwarding the network signal to a second Slimline connector in a first node and / or a third Slimline connector in a second node according to the network signal pin configuration.

[0063] The LAN switch board (LAN SWITCH) provided by the embodiment of the present application can include the LAN switch chip 1, the firmware storage 2, the firmware storage 2 and the RJ45 connector 4.
