Core Product Features
2.1 Premium Industrial Protection Structure
This switch adopts a high-strength die-cast metal housing with excellent durability. It achieves an IP40 protection rating for the main housing and an upgraded IP67 protection grade for all optical ports, effectively preventing dust, water splash and corrosive substances from damaging internal components. Compliant with stringent industrial mechanical standards, it withstands 5g continuous vibration (IEC 60068-2-6) and 15g mechanical shock (IEC 60068-2-27), perfectly adapting to vibration-intensive equipment operation environments.
2.2 All-Fiber Flexible Port Design
Equipped with 8 universal SFP fiber slots, the MM20-Z6Z6Z6Z6SBH supports freely matched single-mode and multi-mode optical modules. It is compatible with 100Mbps and 1000Mbps fiber transmission rates, allowing users to flexibly configure transmission distances according to on-site networking demands. The all-optical port design thoroughly eliminates electromagnetic interference, making it ideal for long-distance cross-region wiring and high-electromagnetic-interference industrial workshops.
2.3 Powerful Industrial Redundancy & Management
Embedded with Hirschmann exclusive HIPER-Ring redundancy technology and standard RSTP/MRP protocols, the switch realizes network fault recovery within milliseconds to avoid communication interruption. It supports comprehensive intelligent management functions including VLAN division, QoS traffic priority optimization, IGMP Snooping multicast filtering, port mirroring and broadcast storm suppression. Users can conduct remote configuration and real-time monitoring via web page (HTTP/HTTPS), SSH command line and HiVision industrial network management software, simplifying daily operation and maintenance.
2.4 Stable Redundant Power Supply System
The device is equipped with dual redundant DC power input interfaces to avoid single-point power failure risks. Built-in multiple protection circuits cover reverse polarity protection, overvoltage protection and lightning surge protection conforming to EN 61000-4-5 standard. It can resist unstable voltage fluctuation and instantaneous surge in industrial power grids, ensuring continuous and safe operation of the equipment.
2.5 Ultra-Wide Temperature Environmental Adaptability
Maintaining consistent working performance in extreme temperatures, the operating temperature ranges from -40°C to +75°C, while the storage temperature covers -40°C to +85°C. The applicable relative humidity is 5% to 95% (non-condensing), enabling stable operation in high-temperature, low-temperature, humid and dusty harsh industrial environments without additional heat dissipation or thermal insulation devices.
