Industrial-Grade 28-Port Gigabit Switch With Fiber Ports & Wide Temperature Support
The H3C LS-IE4500-28S-G is a rugged 28-port Gigabit Ethernet switch designed for demanding industrial environments. Featuring all-SFP fiber ports, this switch ensures high-speed, long-distance data transmission while withstanding extreme temperatures (-40°C to 75°C). Its fanless, IP40-rated design enhances durability in harsh conditions, making it ideal for power utilities, smart factories, and outdoor deployments.
✔ Industrial Reliability – Operates in wide temperature ranges (-40°C~75°C) with high EMI resistance (EMC Level 4).
✔ 28 Gigabit SFP Ports – Supports fiber connectivity for extended reach (multi-mode/single-mode options).
✔ Redundant Power Input – 12-48V DC dual power supply ensures continuous operation.
✔ Millisecond-Level Fault Recovery – Supports ERPS (Ethernet Ring Protection Switching) and RSTP/MSTP for self-healing networks.
✔ Fanless & Low Power Consumption – Reduces failure risks in dusty/vibratory environments.
✔ Industrial Protocol Support – Compatible with Modbus TCP, DNP3, and other OT protocols.
