The MDS-G4000 Series industrial switches offer 12/20/28-port Gigabit mix-and-match modularity, ideal for flexible network expansion. With a highly durable housing smaller than a 3U half-rack, these switches are designed to fit in confined spaces and operate in the harsh environments common in substation, mining, and oil and gas applications. The MDS-G4000 switches offer a variety of hot-swappable media modules (RJ45, SFP, PoE) and power units (24/48VDC, 110/220 VAC/VDC) to provide even greater flexibility and availability, especially for continuity-critical operations.
