Industrial-Grade PoE+ Switch With 20 Ports , Wide Temp & ERPS
Ring For Harsh Environments
The H3C LS-IE4320-20P is a rugged industrial Ethernet switch
designed for demanding environments, offering high reliability,
PoE+ support, and ultra-fast redundancy for critical networks. With
20 ports (16x Gigabit PoE+ RJ45 + 4x SFP fiber slots), this switch
ensures flexible connectivity for IP cameras, wireless APs, PLCs,
and industrial IoT (IIoT) devices. Its industrial-grade design
(-40°C to 75°C operating range, IP40 protection, and vibration
resistance) makes it ideal for manufacturing plants,
transportation, power utilities, and outdoor deployments.
Key Features & Benefits:
✅ Industrial Durability – Operates in extreme temperatures (-40°C
to 75°C) with IP40-rated protection against dust and moisture.
✅ High-Power PoE+ Support – Delivers up to 30W per port (IEEE
802.3af/at), powering IP cameras, wireless APs, and VoIP phones
without extra cabling.
✅ Ultra-Fast Redundancy – ERPS (Ethernet Ring Protection Switching)
ensures <20ms failover, minimizing downtime in mission-critical
networks.
✅ Flexible Connectivity – 16x 10/100/1000M PoE+ ports + 4x Gigabit
SFP slots for fiber uplinks, supporting long-distance connections.
✅ Dual Power Inputs – 24V DC or 110/220V AC options with redundant
power support for uninterrupted operation.
✅ Advanced Management – Supports CLI, Web, SNMP, and LLDP for easy
monitoring and integration into H3C iMC network management systems.
