Managed Hardened Switch Lantronix SISGM1040-284-LRT — 8× 10/100/1000Base-T + 4× 100/1000 SFP

Lantronix Managed Hardened Switch SISGM1040-284-LRT is an industrial-grade Layer 2 switch that combines eight Gigabit copper ports with four SFP fiber-capable slots. Built for harsh environments, the device supports both 10/100/1000Base-T copper connections and 100/1000 SFP modules, enabling mixed media deployments for local devices and uplinks. The switch includes managed switching features, remote management and redundancy options suited for transportation, outdoor cabinets, factory floors and other demanding network locations.

Advantages

This hardened switch provides a compact, managed solution for converging copper and fiber links while maintaining industrial reliability. It supports full Gigabit copper throughput on eight RJ45 ports and flexible SFP-based fiber or fiber/copper uplinks at 100/1000 speeds. Built for rugged environments, the unit offers managed Layer 2 features and remote administration capabilities to simplify integration, monitoring and troubleshooting across distributed or critical networks.

Suitable for

• Industrial Ethernet networks connecting PLCs, HMIs and automation controllers
• Transportation systems and roadside cabinets requiring weather-tolerant equipment
• Outdoor or edge deployments that need mixed copper and fiber connectivity
• Networks needing managed Layer 2 features such as VLANs, QoS and link redundancy

When it may not be suitable

As a Layer 2 managed hardened switch, this unit is not designed for Layer 3 routing or advanced firewall functions; networks requiring integrated routing, NAT or deep security functions will need additional devices. It is intended for industrial or outdoor use cases; for small office or purely indoor home networks a standard unmanaged or consumer-grade switch may be more cost-effective.

Key specifications

• Port configuration: 8 × 10/100/1000Base-T RJ45 copper ports
• Fiber uplinks: 4 × SFP slots supporting 100/1000 Mbps SFP modules
• Switching layer: Layer 2 managed switching with VLAN and QoS support
• Management: Remote management and monitoring (SNMP/CLI/web interface where supported)
• Environment: Designed for hardened/industrial deployment with appropriate enclosure and operating conditions

How to use

Install the switch in an appropriate industrial cabinet or mounting location with suitable environmental protection and power input. Populate SFP slots with compatible 100 or 1000 Mbps modules as required, and connect endpoints to the RJ45 ports using standard Ethernet cabling. Use the device's management interface to configure VLANs, QoS, link aggregation and redundancy features, and enable remote monitoring for ongoing status checks and diagnostics.

What to consider before purchase

• Required media types: confirm whether your uplinks require 100 Mbps or 1 Gbps SFP modules and source compatible SFPs
• Desired managed features: verify support for specific Layer 2 functions such as VLANs, QoS, link aggregation and redundancy protocols
• Environmental ratings: ensure the switch enclosure and operating temperature range match your installation site requirements
• Power and mounting: check available power inputs and mounting options for racks, DIN rail or cabinets in your deployment

Usage recommendations

For reliable operation in industrial or outdoor networks, pair the switch with high-quality SFP modules that match fiber type and distance requirements, configure VLANs to segment traffic, and enable redundancy protocols to maintain uplink availability. Regularly monitor link status and temperature via the management interface and schedule firmware updates through controlled maintenance windows.
