Hardened L2+ 24-Port Gigabit Switch with 4 SFP USB-C Easy Management
Overview
The ETH-DIMC2424M Series is not just another industrial Ethernet switch — it combines
24 Gigabit RJ45 ports, 4 SFP uplinks, and a USB-C management interface that
replaces traditional RS232 for faster, simpler deployment. Engineered with a fanless IP40
aluminum case, -40°C to +80°C temperature tolerance, and redundant 12~48VDC
power inputs, it ensures uninterrupted connectivity in extreme conditions. With advanced
L2+ features including VLAN, QoS, ERPS ring redundancy, and robust security such as
SSH/HTTPS/802.1X, it delivers enterprise-grade reliability to industrial networks.
Features
Unique USB-C management port – no need for RS232 serial access
24 × Gigabit RJ45 + 4 × SFP ports, 110Gbps switching capacity
Hardened IP40 aluminum chassis, fanless & vibration-resistant
Wide -40°C to +80°C operation for harsh environments
Redundant 12~48VDC power with automatic reset protection
Advanced redundancy: STP/RSTP/MSTP/ERPSv2 ring recovery
Robust security: SSH, HTTPS, RADIUS, 802.1X, DoS/DDoS defense
Industrial protocols support: IGMP Snooping, QoS, ACL, VLAN Q-in-Q
High reliability: MTBF > 200,000 hrs, CE/FCC/EN/IEC certified
