Example 3 Redundant Application

In a redundant application for high network availability where a rack- mountable managed switch with over 24 ports is required with dense port features, Magnum 6K32’s equipped with redundant LAN features like S-Ring, RSTP, Link-Loss-Learn and various security features are easily qualified for the application. The -48VDC input power option with Dual Source is a useful option in telecom central offices.

The Magnum 6K32 with two Gigabit ports in the modular slot allows it to connect into a Gb mesh structure with RSTP and S-Ring combo used in a no- single-point-of-failure self-healing LAN topology along with a ring of multiple 6K25s at the edge to efficiently recover from a fault in the network. The industry standard Rapid Spanning Tree Protocol 802.1d is used in top eight switches (see diagram below) to perform GB mesh fault recovery, whereas the bottom ring setup has been configured with S-Ring and Link-Loss-Learn for faster recovery in a big ring.

A redundant LAN setup not only provides a reliable recovery solution
