This industrial Gigabit PoE Ethernet switch features 16 Gigabit Ethernet RJ45 ports and 8 100/1000Base-X SFP slots, making it ideal for demanding environments such as industrial networking, intelligent transportation systems (ITS), military, and utility applications. It provides 8 IEEE 802.3af/at PoE+ ports, each capable of delivering 30W of power, with a total PoE power budget of 240W. The fanless, rugged design, housed in an IP30-rated enclosure, is built for durability and operates with a redundant dual power input (48VDC), ensuring reliable performance in harsh conditions. Additionally, it offers advanced features such as cable diagnostics for identifying faults, support for up to 5 ring topologies (μ-Ring, μ-Chain, or Sub-Ring), and quick recovery times of less than 10ms in a ring setup of up to 250 devices. The switch also supports EMS management for efficient network control.
