Comnet CNFE4SMSPOE Compact 4-Port Self-Managed PoE Switch

Overview

The Comnet CNFE4SMSPOE is a four-port self-managed Ethernet switch with integrated Power over Ethernet (PoE) delivery. It consolidates data from three camera ports into a single uplink port, then forwards traffic to your network backbone — solving the common problem of running separate power and data runs to distributed IP cameras in corridors, loading docks, or outdoor utility areas. No programming required; it ships pre-configured and ready to plug in.

Compatibility

Works with any 10/100 Mbps IP camera, access control reader, or intercom device that accepts IEEE 802.3at PoE (High PoE). Each of the four ports delivers up to 30W, supporting mid-range domes, turrets, and bullet cameras from Axis, Hikvision, Uniview, Hanwha, and other major surveillance manufacturers. The uplink port connects to your primary PoE injector, PoE switch, or NVR — no daisy-chaining required.

Installation Notes

Mount via wall bracket, DIN-rail adapter (sold separately; model DINBKT1), or optional rack frame. Operating range -40°C to +75°C handles outdoor equipment sheds and uninsulated utility closets. Auto-negotiation on all ports eliminates crossover-cable headaches. Maximum power consumption is 12W, so the unit itself draws minimal overhead from your main PoE supply. Use a 48 VDC power input (included power supply rated 5A). MTBF exceeds 100,000 hours; typical lifespan in harsh environments is 10+ years with no moving parts.
