IES-3080 is a managed redundant ring Ethernet switches with 8x10/100Base-T (X) ports. Ring Main Units are compact modules that are gas-insulated and sealed, comprising main switching devices and ancillary components to ensure continuous secondary power distribution. The precise arrangement and configuration of components always depend on the particular application and loading. A leading multi-site mining corporation, operating some of the nation's most significant mineral extraction sites, faced the critical challenge of establishing a reliable, 24/7 communication network in the harsh and hazardous conditions of their underground tunnels. To ensure the safety of their. Device Level Ring (DLR) is a Layer 2 protocol that enables redundancy in a ring topology, providing fast network fault detection and reconfiguration for industrial networks. DLR network includes at. The basic building block for a 'ring' network is the 3-Port switch as shown in Figure 1 below. Ring Network using Ethernet 3-Port Switch Unlike a token-ring network, which has been the basis of much of the evolution of the IEEE 802.
