Supports 5 ring instances, with μ-Ring, μ-Chain, or Sub-Ring topology options
μ-Ring provides redundant cabling with recovery time <10ms for up to 250 devices
Supports EMS management for monitoring and configuration

The IGS-402SM-4PU is a rugged, industrial-grade managed Ethernet switch designed for demanding environments. It features four Gigabit Ethernet RJ45 ports, each capable of delivering up to 60W of Power over Ethernet (PoE+) for high-power devices, with a total PoE budget of 240W. Additionally, it includes two 100/1000Base-X SFP slots for flexible fiber optic connectivity, ideal for long-distance transmission. This fanless switch is built for durability, with a high Mean Time Between Failures (MTBF), 4KV surge protection, and a wide operating temperature range, making it suitable for industrial automation, data centers, intelligent transportation systems, and military applications. The switch offers redundant 48VDC power input for continuous operation, and its advanced features include cable diagnostics for identifying opens and shorts, as well as support for flexible network topologies with up to five ring instances (μ-Ring, μ-Chain, or Sub-Ring), ensuring fast recovery times of under 10ms in networks with up to 250 devices. The IGS-402SM-4PU also supports EMS management for easy monitoring and configuration.
