Industrial-Grade Ethernet Switch With 24x100M & 4x1G Ports , Wide-Temp Support For Harsh Environments
The H3C LS-IE4120U-28TP-H1 is a rugged industrial-grade Ethernet switch designed for harsh environments, featuring 24x 10/100M ports and 4x Gigabit combo ports (SFP/RJ45) for high-speed connectivity. Built to withstand extreme conditions, it operates in a wide temperature range (-40°C to 75°C) and offers IP40 protection against dust and EMI interference, making it ideal for industrial automation, smart transportation, and power utility networks.
✔ Industrial Durability – Fanless design, DIN rail mounting, and 12-48V DC/24V AC dual power input ensure reliable operation in demanding settings.
✔ High-Speed Networking – 4x Gigabit uplink ports (SFP or copper) enable seamless backbone connectivity.
✔ Fast Redundancy – Supports ERPS (Ethernet Ring Protection Switching) with <50ms failover, minimizing downtime.
✔ Industrial Protocol Support – Optimized for Profinet, Ethernet/IP, and IEEE 1588v2 (PTP) for precise synchronization.
✔ Advanced Security & QoS – Features VLAN, ACL, 802.1X authentication, and traffic prioritization for secure, stable data transmission.
