[0002] With the development of information technology, especially the rise of emerging technologies such as the Internet, terminal technology, cloud computing, and big data in the 21st century, mankind has entered the era of information explosion. The explosive growth of data has put forward higher requirements for data storage, processing, and application, and has also promoted the market demand and development prospects of data storage products such as servers and storage. However, due to the late start of computer information technology in my country and relatively weak technology, domestic server products have long been under the monopoly of foreign giants in the market and technology fields, and the development strength is limited. At present, the server products on the market in my country mainly use foreign processor chip solutions (such as Intel, AMD, HP and other chips). Some servers that use domestic processor chips also use foreign chips for their core chipsets.

[0003] The core components of the server (processors and chipsets) are foreign products, which cannot be independent, safe and controllable, and there are great information security risks, and the hardware cost is high; core components such as processors and chipsets are completely imported, which is easy to cause resource dependence. Once the international situation changes and a chip embargo occurs, it may cause an embarrassing situation where no chips are available and no chips can be replaced, affecting industrial development; domestic EEB servers are relatively single in type and lack product diversity, which is not conducive to the localization process. Therefore, we have made improvements to this and proposed a switch motherboard based on the Shenwei 121 processor and network switching chip. Summary of the invention

[0009] As a preferred technical solution of the present invention, the Ethernet PHY is provided with M, M and M Ethernet interfaces, and is connected to the RJ45 socket through a 100M transformer.

[0010] As a preferred technical solution of the present invention, the Shenwei 121 processor is externally connected to an RS232 serial port transceiver via a UART interface, and the RS232 serial port on the RS232 serial port transceiver realizes power isolation through a power isolation chip.

[0011] As a preferred technical solution of the present invention, the power timing control chip is connected to a power supply via a CPLD interface.

The processor and the chipset are both independently designed by my country, which further breaks the monopoly of foreign chips in servers from the core components. At the same time, the product takes into account the design characteristics of autonomy, controllability and security, can better meet the information security requirements, and can be better applied to my country's information industry and other fields.
