Hirschmann RS20-0800M2M2SDHE

Key Features and Specifications 

1. Managed Layer 2 Capabilities:

   • As a managed switch, it supports essential features like VLAN (IEEE 802.1Q), QoS (IEEE 802.1p), RSTP/MSTP for network redundancy, and IGMP Snooping for efficient multicast traffic management.

2. Robust Industrial Design:

   • DIN-rail Mountable (M2): Standard for control cabinet installation.

   • Wide Temperature Range: Typically operates from -40 °C to +70 °C.

   • High EMC Immunity: Designed for industrial environments with heavy electrical noise.

   • Redundant Power Supplies (S&D): The dual 24VDC inputs ensure high availability. If one power supply fails, the switch continues operating from the other.

3. Advanced Features of the RS2 Series:

   • Fast Redundancy: Supports Hirschmann's proprietary HIPER-Ring protocol, which offers extremely fast network recovery times (< 50 ms). It also supports standard protocols like RSTP.

   • Security: Features like Port Security, 802.1X network access control, and management access control lists (ACLs).

   • Comprehensive Diagnostics: Detailed status and statistics monitoring via web interface, CLI, or SNMP.

     
     

     
     

     The Hirschmann RS20-0800M2M2SDHE is a robust, reliable, and fully-featured industrial workhorse. Its value lies in its proven track record, high availability features (dual power, HIPER-Ring), and comprehensive management set. It is an excellent choice for modernizing or building a network where Gigabit speed is not yet a requirement but where reliability and redundancy are paramount. It is the kind of switch you install and forget about, trusting it to operate for years in a demanding environment.
