S-Ring for Magnum 6K Switches - Software for Redundancy Management

Magnum S-Ring™ Redundancy Manager software product, built upon networking industry standards including IEEE 802.1w Rapid Spanning Tree Protocol (RSTP) and 802.1d Spanning Tree Protocol (STP), enables Magnum 6K Managed Switches to simplify and speed up recovery from faults in Industrial Ethernet LAN configurations that use a ring structure. With S-Ring, fault tolerant LANs finally can have both standards and speed.

Speak To An Expert

Fast fault-recovery - in Ethernet LAN ring structures
Extensions - to industry standard Spanning Tree Protocol
Multi-vendor hubs and switches - supported in the rings--both managed and unmanaged
Large rings (50+ members) - over long distances using fiber media
User controlled set-up - for ring management via software commands
Auto Ring-Learn - Scan feature
Ring-Scan feature - simplifies ring definitions and makes reliable installation easy
