Comnet Hardened 3 Port 1000Mbps + 7 Port 100Mbps Managed Switch Includes Power Supply - RLGE3FE7MS4

Comnet RLGE3FE7MS4 Hardened Managed Ethernet Switch

Overview

The RLGE3FE7MS4 is a 10-port hardened managed Layer 2 switch designed for industrial and utility environments where commercial gear fails — substations, railway enclosures, hazardous locations, and outdoor telecommunications huts. It combines seven 100Mbps ports with three dual-rate gigabit ports (1G SFP combo) in a compact DIN-rail form factor rated for -40 to +85°C operation without derating. Redundant power inputs (12–60 VDC LV model or 85–264 VAC / 88–370 VDC HV model) eliminate single points of failure during grid outages or battery switchovers. The switch is rated for Class 1 Division 2 hazardous locations (Groups A, B, C, D) and complies with IEC 61850-3, IEEE 1613 Class 2, and EN50155 railway standards — critical certifications for substation automation, renewable energy sites, and rail-integrated networks.

Compatibility

The RLGE3FE7MS4 integrates into any IP surveillance, SCADA, or networked sensor deployment requiring industrial-grade switching. The seven 100Mbps Fast Ethernet ports support standard IP cameras, PTZ controllers, and access control readers drawing minimal bandwidth. Three 1000BASE-Tx / 100/1000BASE-Fx SFP combo ports allow fiber uplinks for long-distance backbone runs (critical where ground loops or lightning strike risk demands optical isolation) or gigabit aggregation to NVRs and core network equipment. Managed Layer 2 features—VLAN (802.1Q, up to 4096), LACP port trunking, RSTP/MSTP failover, and port mirroring—interoperate with standard ONVIF cameras, Milestone VMS, and enterprise network management tools (SNMP v1/v2c/v3, Syslog, SNMP Trap). The switch does not require custom firmware; standard surveillance and industrial VMS platforms recognize it as a transparent backbone device.

Installation Notes

Mount on 35mm DIN rail; requires secure enclosure with IP30 ingress protection (fan-cooled, sealed cabinet recommended for full -40 to +85°C rating in outdoor installations). Redundant power inputs accept 12–60 VDC (LV) or 85–264 VAC / 88–370 VDC (HV) simultaneously—wire both inputs for failover resilience. A C-Ring topology recovers from a single cable break in <30ms; configure RSTP or MSTP on daisy-chained devices to enable this. SFP ports accept standard LC fiber modules; multimode OM3/OM4 or singlemode OS2 supported. The 7.4 Gbps switching bandwidth and 7 µS latency ensure real-time video streams (multiple H.265 camera feeds) and SCADA polling do not block each other. Test IEEE 802.1x RADIUS authentication and port security rules in a staging environment before deployment in critical infrastructure.
