Comnet CNGE2FE4SMSPOEHO Hardened PoE Ethernet Switch

The CNGE2FE4SMSPOEHO is a 6-port self-managed switch combining four 10/100 Mbps copper ports with two 1000 BASE-FX optical SFP ports. No programming required—it ships pre-configured with dip switch selection for fiber uplink or unmanaged bridging. This is the switch to deploy when you need copper PoE for edge cameras alongside fiber backhaul in a hardened environment.

Overview

Mixed copper-optical architecture lets you run PoE-powered devices (IP cameras, access points) on four copper ports while extending uplink distance via single-mode or multimode fiber SFP modules. Ports 1 and 2 deliver up to 30W PoE+ each; Ports 3 and 4 deliver up to 60W PoE+ each—meaning you can power multiple cameras and edge devices per port without external injection. Operating range of -40°C to +75°C and compliance with NEMA TS-1/TS-2 and Caltrans specifications make this suitable for traffic control cabinets, outdoor shelters, and telecom enclosures where temperature swings and vibration are routine.

Compatibility

Works with any standard IP camera, network device, or PoE-compatible equipment drawing ≤60W per port. Auto-negotiation on copper ports handles 10 Mbps, 100 Mbps, or 1000 Mbps speeds and full/half duplex automatically—no manual config needed. SFP ports accept Comnet or standard 1000 BASE-FX modules (single-mode or multimode). Integrates into Axis, Hikvision, Milestone, or any ONVIF-based VMS without special drivers.

Installation Notes

Requires external 48–57 VDC power supply (5A maximum with PoE, 1A without) sold separately. Wall or flat-surface mounting via screw attachment. Voltage transient protection on all power and signal lines guards against surge events. Automatic resettable current limiters prevent port shutdown from short-circuit. Operating humidity range of 0–95% (non-condensing) and MTBF >100,000 hours support long unattended duty cycles in shelters and cabinets.
