Industrial-Grade Gigabit PoE++ Switch With ERPS Redundancy & Wide Temperature Support H3C LS-IE4320-10S-UPWR
The H3C LS-IE4320-10S-UPWR is a rugged industrial-grade Gigabit Ethernet switch designed for harsh environments, offering high-speed connectivity, PoE++ power delivery (IEEE 802.3bt), and ultra-reliable network redundancy. Built to withstand extreme temperatures (-40°C to 75°C) and industrial conditions, this switch ensures stable performance in smart factories, transportation, energy, and outdoor deployments.
✅ Industrial Durability – IP40-rated, fanless design, and high EMC resistance for reliable operation in dusty, humid, or high-interference environments.
✅ High-Power PoE++ Support – Delivers up to 30W per port (IEEE 802.3bt/at/af), powering IP cameras, wireless APs, and industrial IoT devices without extra wiring.
✅ Ultra-Fast Network Redundancy – Supports ERPS (Ethernet Ring Protection Switching) with <50ms failover, plus STP/RSTP/MSTP for loop prevention.
✅ Flexible Connectivity – 8x 10/100/1000Base-T ports + 2x SFP fiber slots (Combo), enabling hybrid copper/fiber uplinks.
✅ Precision Timing Sync – IEEE 1588v2 (PTP) support for industrial automation and smart grid applications.
✅ Easy Management – Web, CLI, and SNMP management, compatible with H3C iMC for centralized control.
