LevelOne 20-Port L2 Plus Managed Gigabit Industrial Switch, 16x 1GbE RJ45, 4x 1/2.5GbE SFP, DIN-Rail, -40°C to 80°C

The LevelOne IGU-2071 is a rugged, managed L2+ industrial Ethernet switch designed for demanding environments and industrial automation. It provides 16 10/100/1000Base-T RJ45 ports and 4 1000/2500Base-X SFP ports, a switching capacity of 52 Gbit/s and a MAC address table of 16,000 entries to handle dense network traffic while withstanding harsh conditions. The switch supports redundant DC power input, advanced surge and ESD protection, and a wide operating temperature range for reliable long-term operation.

Advantages

The device delivers fast failover with G.8032 ERPS protocol and sub-20 ms recovery time to maintain network availability. It includes extensive Layer 2 features such as VLAN, STP/RSTP/MSTP, Link Aggregation, QoS and IGMP Snooping for traffic optimization. Management options cover Web, SNMP, CLI, Telnet and SSH interfaces, and USB one-key simplifies configuration and firmware upgrades. Built for industrial use, it provides redundant 12–75 V DC power support, 6 kV surge protection and ESD protection (Air 15 kV, Contact 8 kV), all in a fanless IP40 DIN-rail enclosure rated for −40 °C to +80 °C.

Suitable for

• Industrial automation networks
• Transportation and utility networks requiring rapid failover
• Factory floors and harsh-environment installations
• Edge aggregation for surveillance and IoT devices

How to use

Mount the switch on a DIN-rail in a suitable enclosure or cabinet and connect redundant DC power sources within the specified 12–75 V range. Connect RJ45 and SFP devices according to your network design and configure L2 features (VLAN, link aggregation, STP variants) via the web GUI, CLI, SNMP or USB one-key. Enable ERPS to provide fast ring recovery and configure QoS and IGMP Snooping for optimized traffic handling. Apply 802.1X and ACL settings to enforce port-level security as required.

Recommendations

For reliable operation in industrial environments, use proper surge-protected cabling, implement redundant power feeds, and keep the unit within the specified temperature range. Regularly update firmware via the USB one-key or management interfaces and validate ERPS and STP configurations in a test environment before deploying to production networks.
