LevelOne 28-Port L2 Plus Managed Gigabit Fiber Industrial Switch, 4x 1.25/2.5GbE SFP, 16x 1.25GbE SFP, 8x Gigabit SFP/RJ45 Combo, Redundant Power Supply, -40°C to 80°C

The LevelOne IGU-2872 is a rugged L2+ managed industrial Ethernet switch designed for demanding industrial environments. It provides high-density fiber and copper connectivity with 16x 100/1000Base-X SFP ports, 8x Gigabit SFP/RJ45 combo ports and 4x 1G/2.5GBase-X SFP ports. Built for continuous operation, the switch supports redundant AC/DC power, advanced surge and ESD protection, and a wide operating temperature range from -40°C to +80°C in a fanless, IP40 rack-mount enclosure.

Advantages

The IGU-2872 delivers rapid network recovery through G.8032 ERPS with sub-20 ms failover and advanced Layer 2 functionality including VLAN, STP/RSTP/MSTP, Link Aggregation, QoS and IGMP Snooping. It supports robust management interfaces (Web, SNMP, CLI, Telnet, SSH) and simplifies maintenance with USB one-key configuration. Security features include 802.1X authentication, port isolation and ACL. The switch also offers IPv4/IPv6 static routing and DHCP server functions for enhanced Layer 3 capability.

How to use

Install the IGU-2872 in a standard 19-inch rack and connect fiber or copper links to the appropriate SFP or RJ45 combo ports. Configure network parameters and security using the web interface, CLI, SNMP or SSH. Use the USB one-key function to apply saved configurations or perform firmware upgrades. For redundant power, connect both AC and DC power sources according to the installation manual.

Recommendations

Place the switch in a clean, ventilated rack position protected from direct moisture. Use approved SFP transceivers compatible with 1.25/2.5GbE and 1G SFP ports. Regularly back up configuration files and verify ERPS topology when deploying in ring architectures to ensure sub-20 ms recovery.
