Brand strength endorsement
Hirschmann, as a leading brand in the field of industrial networks, has been established since 1924, after nearly a hundred years of technical precipitation and market cultivation. Hirschmann has achieved outstanding results in the fields of broadcasting and television transmission technology, enterprise and industrial network solutions. In 1984, Hirschmann built the world’s first fibre-optic Ethernet, and in 1990, it launched HIPER – Ring, which has established its position at the forefront of industrial network technology.

With deep technical accumulation and rich experience, its products are known for high reliability and excellent performance, which can operate stably in extreme industrial environments such as high temperature, high pressure and strong electromagnetic interference, and its business covers the whole world, which provides a solid brand guarantee for MM20 – m2 m2 t1 sahh managed Ethernet switch.

Port Configuration and Connectivity
Ethernet Ports: The switch will most likely be equipped with Ethernet ports that support 10/100/1000Base-T adaptive rates, using standard RJ-45 interfaces. This design enables a transmission distance of up to 100 metres when using standard Cat5e, Cat6 or higher Ethernet cables, which can easily and seamlessly connect with industrial controllers, smart sensors, computers and other types of Ethernet devices, ensuring stable and reliable short-distance data transmission in the industrial field to meet the needs of data interaction between devices on the factory floor.

Optical Fibre Port: Considering the demand for long distance and high bandwidth transmission in industrial scenarios, it is likely to be equipped with an optical fibre port. If it is a multi-mode optical fibre port, the transmission distance is estimated to be up to 550m when 50/125μm optical fibre is used and the transmission rate is 1000Mbps, which is suitable for scenarios where different workshops and floors within the factory are in relatively close proximity to each other, but have higher requirements for the data transmission rate, such as the data communication between the equipment of the stamping workshop and the welding workshop of the automobile manufacturing factory.

When equipped with single-mode fibre ports, the transmission distance can be greatly extended to several kilometres when using single-mode fibre at 1310nm wavelength, which is significant for data communication across plants in large industrial parks, or for long-distance data transmission between substations and remote monitoring centres in smart grids. Fibre optic ports may be of the common SC, LC type, with easy plugging and unplugging, solid connection characteristics, in line with the requirements of industrial environments on the stability and convenience of equipment connection.

Data processing and transmission performance
High-performance data forwarding: High-performance switching chips and optimised forwarding algorithms are used internally to achieve fast data forwarding. In industrial automation production lines, a large amount of sensor data needs to be transmitted to the control system in real time, MM20 – m2 m2 t1 sahh can accurately forward the data to the target device in a very short time, to ensure the timeliness of the production data, to ensure the efficient operation of the production line.

VLAN Support: Supports Virtual Local Area Network (VLAN) technology, which can divide a physical network into multiple logically independent virtual networks. In the enterprise network, the data of different departments or business areas can be isolated and managed through VLANs, for example, dividing the production equipment network and office network into different VLANs, which improves network security and management efficiency while avoiding the impact of broadcast storms on network performance.

QoS (Quality of Service): With QoS (Quality of Service) function, it can differentiate the processing according to the type and priority of data. For control data in industrial automation with high real-time requirements, a higher priority can be set to ensure that it is transmitted first when the network is congested, so as to avoid production accidents caused by network delays, while for non-critical monitoring data and so on, a lower priority can be set to reasonably allocate network bandwidth resources.

Network Management Functions
Multiple management methods: As a managed Ethernet switch, it supports rich management methods. It can be configured via command line interface (CLI), which is suitable for professional network engineers to set complex parameters; it also supports Telnet remote management, which is convenient to configure and monitor the switch remotely. At the same time, it provides web interface management, with intuitive graphical interface, allowing non-professionals to easily perform basic configuration operations, such as setting port parameters, checking network status, and so on.

Port monitoring and statistics: It can monitor the status of each port in real time, including the connection status of the port, data traffic, number of error frames and other information. Through these real-time monitoring data, network administrators can timely detect network failures or abnormal traffic, such as port connection interruption, data traffic abnormally increased, etc., and handle the situation accordingly. In addition, the port data can be statistically analysed, such as the average flow rate and peak flow rate over a period of time, providing data basis for network optimization and expansion.

Security Management: Support Access Control List (ACL), which can restrict network access according to source IP address, destination IP address, port number and other conditions. For example, only devices with specific IP address segments are allowed to access the production network, preventing unauthorised devices from accessing and safeguarding the security of the industrial network. At the same time, it may support 802.1X authentication to ensure that the identity of devices accessing the network is legitimate through the authentication mechanism, further enhancing network security.
V. Reliability and Environmental Adaptability

Redundant design: Some models may adopt redundant power supply design, equipped with two or more power input interfaces, so that when one power supply fails, the other power supply can automatically take over the work to ensure the continuous operation of the switch and avoid network interruption due to power failure. In terms of network connection, it supports link redundancy function, which transmits data through multiple network links, and when one link fails, the data can be automatically and quickly switched to other normal links to ensure uninterrupted network communication, which is suitable for industrial application scenarios that require high network reliability, such as electric power system monitoring network, chemical production control system, and so on.

Industrial-grade design: Strictly designed and manufactured in accordance with industrial-grade standards, it can adapt to harsh industrial environments. The internal electronic components have been strictly screened and have the characteristics of high temperature resistance, low temperature resistance, humidity resistance, dust resistance, etc. The shell design can effectively prevent dust and water, and the internal structure can resist a certain degree of vibration and impact. For example, it can operate stably in the high temperature smelting workshop of steel factory, dusty and humid environment of coal mine, outdoor power substation and other harsh places to ensure the reliable connection of industrial network.
