Industrial-Grade H3C LS-IE4120U-5E Switch : Wide-Temperature , PoE+
Ready & High Reliability
The H3C LS-IE4120U-5E is a rugged 5-port Gigabit industrial
Ethernet switch designed for harsh environments, including
factories, power utilities, and transportation systems. Built to
withstand extreme temperatures (-40°C to 75°C) and vibrations, this
IP40-rated switch ensures stable connectivity in demanding
conditions.
Key Features:
✅ Industrial Durability – Fanless design, high EMI resistance, and
compliance with IEC 61000-4-3/4/5/6 standards for reliable
operation in noisy electrical environments.
✅ Flexible Connectivity – 5× 10/100/1000Base-T ports with
auto-negotiation, supporting PoE+ (IEEE 802.3af/at, 30W per port)
for powering IP cameras, wireless APs, and IoT devices.
✅ Fast Network Redundancy – Supports ERPS (Ethernet Ring
Protection, <50ms failover) and STP/RSTP/MSTP to prevent
downtime in mission-critical networks.
✅ Enhanced Security – Features 802.1X authentication, ACL, port
security, and DHCP Snooping to block unauthorized access.
✅ Easy Management – Web, CLI, and SNMP v1/v2c/v3 support,
compatible with H3C iMC for centralized monitoring.
