Hirschmann Brand Advantages
Hirschmann has a longstanding reputation in the field of industrial networks, with a deep history and excellent technical strength. Since its establishment in 1924, Hirschmann has been making breakthroughs in technological innovations, from the early innovation of broadcasting and television transmission technology to the later pioneering of enterprise and industrial network solutions. 1984, Hirschmann successfully constructed the world’s first fibre-optic Ethernet, and in 1990, it launched the HIPER – Ring technology, which has continued to set the trend for the development of the industry. With nearly 100 years of experience, Hirschmann products occupy an important position in the global industrial market with their unrivalled reliability and high performance, and the MM20 – s 2s 2m 2 sahh managed Ethernet switch is a strong testimony to the brand’s strength.

Port Setting and Connection Characteristics
Ethernet ports: The switch is most likely to be equipped with multiple Ethernet ports and supports 10/100/1000Base-T adaptive rate function with standard RJ-45 interface. In practical application scenarios, when using standard Ethernet cables such as Cat5e, Cat6, etc., the transmission distance can reach 100 metres stably. This makes it easy to connect industrial controllers, smart sensors, computers and other Ethernet devices in industrial automation production lines, ensuring efficient and stable data transmission over short distances within the factory floor.

Fibre optic port: In view of the urgent need for long-distance, high-bandwidth data transmission in industrial environments, the MM20-s 2s 2m 2 sahh switch is most likely to be equipped with a fibre optic port. If it is a multi-mode optical fibre port, the transmission distance can reach up to 550m when 50/125μm optical fibre is used and the transmission rate is set to 1000Mbps, which is suitable for scenarios where different workshops and floors within a factory are in relatively close proximity to each other, but the data transmission rate is demanding, such as the data interaction between equipment in different production areas of an electronics manufacturing factory.

In the case of single-mode fibre ports, when 1310nm single-mode fibre is used, the transmission distance can be greatly extended to several kilometres, which is of great significance for long-distance application scenarios such as cross-factory data communication in large-scale industrial parks, or data transmission between the headquarters of a petrochemical company and a remote production base. The fibre optic port type is either SC or LC, which is easy to plug and unplug and has strong connection characteristics, fully meeting the requirements of industrial environments for both reliability and convenience of equipment connection.

Data processing and transmission performance
Fast data forwarding mechanism: The switch is equipped with a high-performance switching chip and adopts optimised forwarding algorithms to achieve extremely fast data forwarding operations. In the complex industrial automation production process, a large number of sensors generate data that need to be transmitted to the control system in real time and accurately, MM20 – s 2s 2m 2 sahh switch can forward these data to the target device in a very short time accurately and without error, which strongly guarantees the timeliness of the production data and ensures that the production line can run efficiently and stably.

VLAN Function Support: Supports Virtual Local Area Network (VLAN) technology, which can logically divide a physical network into multiple independent virtual networks. In a large enterprise network, data from different departments or business areas can be effectively segregated and managed with the help of VLAN technology. For example, dividing the production equipment network and office network into different VLANs can significantly improve network security and network management efficiency, while also effectively avoiding the negative impact of broadcast storms on network performance.

QoS Quality of Service Assurance System: It is equipped with perfect QoS (Quality of Service) function, which can differentiate data according to its type and priority. In the field of industrial automation, for control data with extremely high real-time requirements, a higher priority can be set to ensure that such data can still be transmitted with priority when the network is congested, thus avoiding production accidents caused by network delays. For non-critical monitoring data, a lower priority can be set to achieve a reasonable allocation of network bandwidth resources.

Network Management Function Module
Diversified Management Modes: As a managed Ethernet switch, MM20-s 2s 2m 2 sahh supports rich and diversified management modes. Professional network engineers can perform fine configuration through the command line interface (CLI) to meet the needs of complex network settings; Telnet can also be used for remote management, which is convenient for configuring and monitoring the switch in remote environments. In addition, it also provides Web-based management, which enables even non-professionals to easily perform basic configuration operations, such as setting port parameters and viewing real-time network status, through an intuitive graphical interface.

Port Monitoring and Statistical Analysis: Each port can be monitored in real time, including the connection status of the port, data traffic, the number of error frames and other key information. With the help of these real-time monitoring data, network administrators can detect network failures or abnormal traffic conditions, such as sudden interruption of port connection, abnormal increase of data traffic, etc., and quickly take corresponding measures. In addition, the switch can also perform comprehensive statistical analysis of port data, such as the average traffic volume and peak traffic volume over a period of time, providing valuable data for network optimisation and expansion.

Security Management Mechanism: Supporting Access Control Lists (ACLs), the switch can strictly restrict network access based on various conditions such as source IP address, destination IP address, port number, and so on. For example, in an industrial network, only devices with specific IP address segments are allowed to access the production network, effectively preventing unauthorised devices from accessing the network and effectively safeguarding the security of the industrial network. At the same time, 802.1X authentication may be supported to ensure that the identity of devices accessing the network is legal and compliant through a rigorous authentication mechanism, further enhancing the overall security of the network.

Reliability and Environmental Adaptability
Redundant design guarantee: Some models may adopt redundant power supply design, equipped with two or more power input interfaces. When one of the power supply fails, the other power supply can quickly and automatically take over the work to ensure the continuous and stable operation of the switch, effectively avoiding network interruptions caused by power failure. In terms of network connection, it supports link redundancy function, which transmits data through multiple network links. Once a link fails, the data can be automatically switched to other normal links in a very short time to ensure the continuity and stability of network communication. This feature is especially suitable for industrial application scenarios that require high network reliability, such as electric power system monitoring network and medical equipment remote control network.

Industrial-grade standard: Strictly following the industrial-grade standard for design and manufacturing, it can adapt to all kinds of harsh industrial environments. The internal electronic components have been carefully screened, with excellent resistance to high and low temperatures, humidity, dust and other characteristics, the shell design can be effectively dustproof, waterproof, the internal structure can withstand a certain degree of vibration and shock. Whether in the hot smelting workshop of a steel factory, the dusty and humid working environment of a coal mine, or the complex and changeable climatic conditions of an outdoor power substation, the MM20 – s 2s 2m 2 sahh switches can operate stably and reliably, ensuring that the industrial network is always unimpeded.
