Brand Story
Maissn, In 2000, Mr. Zachary Biao led Huawei's R&D team to create a brand in the United States. In order to better explore the Chinese market, the brand registered a mainland trademark in 2012. The annual export of Meisen industrial switches to Japan exceeds 10000 units. From underwater equipment such as Wuhan CSIC, land-based armored equipment such as Xianyang Northwest Electromechanical Research Institute, Suzhou and Chengdu subway systems, to the integration of the Huawu high-speed railway, to the aerospace satellite of the Institute of Optoelectronics of the Chinese Academy of Sciences, as well as the extensive application in extremely harsh environments such as China Southern Power and China Railway Equipment Manufacturing. In the United States, Japan, China, and other countries, it is known as a "trusted partner in industrial communication" and the "king of cost-effectiveness". According to professional organizations, Maissn has become one of the world's four famous industrial Ethernet switch brands.
Beijing Meisen Technology MS24GMCM12 series full network management Ethernet switch, specially developed for military applications. Supports 12 Gigabit M12 ports with complete management functions, including QoS, VLAN, IGMP Snooping/GMRP, Port Trunking, SNMP V1/V2/V3, etc. Multiple redundant protection protocols such as RSTP/STP/MSTP/EAPS, redundant power input, wide temperature design, and strong electromagnetic interference resistance have improved the reliability of the network.
360 ° Quality Assurance
The quality system of Meisen Technology is divided into three major parts: design quality assurance, customer service quality assurance, and manufacturing quality assurance. These three parts influence, feedback, and enhance each other. It is this continuous improvement (TQM) that has created the Meisen Technology Quality System.

Excellent design quality assurance
Meisen Technology rigorously divides the entire design quality assurance into six parts, namely concept, evaluation, design, verification, trial production, and mass production; Only by passing strict inspections at each stage can we move on to the next stage. In the end, we need to go through six rigorous inspection points to confirm the reliable quality, so that the product can be smoothly born and delivered to the customer.

Rigorous product testing and verification
Only in the verification stage of design quality assurance, there are 9 tests that need to be passed. Only when all products pass these 9 strict tests, will the product be allowed to enter the next stage: trial production stage. During the trial production phase, there will be stricter tests that need to be passed.
