28x 100/1000Base-X SFP with 4x GbE Combo

IGS-S2804TM 28x 100/1000Base-X SFP with 4x GbE Combo





The IGS-S2804TM is an industrial grade Ethernet Switch that is equipped with 28 gigabit SFP ports with 4 combo gigabit ports.The model features fan-less design with redundant, isolated power supplies (2 AC, 2 DC, AC + DC) and can be mounted in 19 inch EIA standard rack. This series offers various layer 2 Ethernet functions (IGMP, VLAN, QoS , Security, IPv6, bandwidth control, and port mirroring) and also supports μ-Ring redundancy protocol that can establish 5 independent rings for flexible applications, especially when employed in backbone infrastructure. Housed in rugged rack mountable enclosures, the model complies with many industrial-grade standards and is ideal for deployments in harsh environments to deliver mission-critical network services.
