Comnet 5 Port Self-Managed Switch 10/100 Mbps Ethernet 5TX (Copper) - CNFE5SMS

Comnet CNFE5SMS 5-Port 10/100 Mbps Self-Managed Ethernet Switch

Overview

The Comnet CNFE5SMS is a five-port, self-managed Ethernet switch purpose-built for surveillance and IP video deployments where plug-and-play simplicity matters more than managed complexity. All five ports operate at 10/100 Mbps and come pre-programmed out of the box — there is no configuration required. The CNFE5SMS combines data from four electrical ports into a fifth uplink port and forwards that traffic to the next network device. This is the right tool if you're deploying multiple IP cameras on a single backbone without the overhead of a managed switch.

Key Features

• 5 × 10/100 Mbps RJ45 Ports: Each port supports Auto-Negotiation between 10 and 100 Mbps, half or full duplex — the switch detects the connected device's speed and adapts automatically. No crossover cable hunting required; automatic MDI/MDI-X crossover is built in, so cameras, computers, and uplink connections work without swapping cables.
• Pre-Programmed, Zero-Configuration Setup: Ship it, mount it, plug in power and Ethernet — the CNFE5SMS is ready to forward traffic immediately. This eliminates weeks of planning typical with managed switches and reduces field commissioning time on multi-camera jobs.
• Dual Operating Modes (Uplink or Unmanaged): The switch selection allows you to run it as an uplink device aggregating four camera ports into one backbone connection, or as a flat unmanaged switch if you prefer all ports equivalent. Flexibility without reprogramming.
• 9–24 VDC Wide Input Range: Powers from 9 to 24 VDC, so you can run it on a dedicated 12V industrial supply, a UPS-backed supply, or even a PoE injector in a pinch. At 12W max consumption, it won't strain a typical power budget on job sites with dozens of cameras.
• Full Environmental Compliance (NEMA TS-1/TS-2, Caltrans Traffic Signal Spec): Operates reliably from −40°C to +75°C and stores safely from −40°C to +85°C. Humidity tolerance to 95% non-condensing makes this suitable for outdoor electrical enclosures, highway locations, and warehouse environments without special cooling or desiccant cartridges. Voltage transient protection on all power and signal lines guards against the surges and spikes common in field installations.
• Multiple Mounting Options: Mount flat to a wall or enclosure surface via screw attachment, snap into a single rack slot using ComFit packaging, or mount to a DIN rail with the optional DINBKT1 adapter. Compact dimensions (6.1 × 5.3 × 1.1 in.) mean it fits in cramped electrical boxes without eating significant real estate.
• Status Monitoring via LED Array: Power and activity LEDs display unit operational status and received signal strength at a glance — a simple visual health check without needing a management interface or software.
• IEEE 802.3 Compliance & Lifetime Warranty: Standards-compliant electronics ensure interoperability with any 10/100 Mbps Ethernet device. Lifetime warranty (verified by manufacturer) removes worry about end-of-life replacement costs on surveillance systems with 5–10-year retention windows.

Integration & Compatibility

The CNFE5SMS pairs with any standard Ethernet-based IP camera or network device operating at 10 or 100 Mbps. It is particularly common in Ethernet network deployments where a lightweight aggregation switch is needed before a backbone or NVR connection. No special VMS or vendor lock-in — it is a passive data forwarder compatible with Axis, Hikvision, Dahua, Uniview, Hanwha, and any ONVIF-compliant IP camera. Automatic resettable solid-state current limiters protect against downstream short circuits, so a failed camera won't cascade into a switch failure.

What's in the Box

• 1 × Comnet CNFE5SMS switch (wall-mount or flat-surface ready)

Frequently Asked Questions

Q: Does the CNFE5SMS require any configuration or management software?

A: No. The CNFE5SMS ships pre-programmed and ready to use. Plug in power, connect Ethernet cables, and it begins forwarding traffic immediately. There is no web interface, SNMP, or console login required.

Q: Can I use the CNFE5SMS in outdoor or high-temperature environments?

A: Yes. The switch is rated for operation from −40°C to +75°C and meets NEMA TS-1/TS-2 and Caltrans traffic signal specifications, making it suitable for outdoor electrical enclosures, highway cabinets, and industrial warehouse settings. Humidity tolerance to 95% non-condensing is standard; if condensation is a concern, order the '/C' conformally coated variant.

Q: What is the maximum cable distance the CNFE5SMS supports?

A: Standard IEEE 802.3 10/100 Mbps Ethernet supports up to 100 meters (328 feet) per port. Longer distances require a fiber converter or repeater.

Q: Can I use the CNFE5SMS for both surveillance cameras and data connections?

A: Yes. The CNFE5SMS is a standard Ethernet switch; it forwards any 10/100 Mbps traffic equally — IP video, audio, or management data. It does not prioritize one traffic type over another, so Quality of Service or bandwidth guarantees are not available.

Q: What mounting options are available?

A: Wall or surface mount via screw attachment (included), single rack slot using ComFit packaging, or DIN-rail mount with the optional DINBKT1 adapter. Compact size (6.1 × 5.3 × 1.1 inches) fits standard electrical boxes and enclosures.

Q: Does the CNFE5SMS include a power supply?

A: Yes. A DC plug-in power supply (90–264 VAC input, 50–60 Hz) is included. The switch itself requires 9–24 VDC input and draws a maximum of 12W.

Karl Wilson

The CNFE5SMS is a no-nonsense aggregation switch for surveillance jobs where you need to consolidate four camera feeds onto a single backbone link without burning hours on switch provisioning. I've deployed dozens of these on fixed-camera retail and warehouse sites, and the pre-programmed logic — combine four ports into one uplink — handles the typical single-floor, single-backbone topology out of the box. The 9–24 VDC wide input range means you can power it from nearly any industrial supply on the truck, and the NEMA TS-1/TS-2 rating lets you leave it in an unheated highway cabinet without thermal management.

Technical Highlights:

• Automatic MDI/MDI-X & Auto-Negotiation: You don't need crossover cables or speed-matching cables. Every port detects the connected device (camera, computer, uplink) and adapts its speed and pin configuration on the fly. Real-world upside: field swaps are faster, and you don't waste time on cable inventory or diagnostic troubleshooting.
• 12W Max Power Draw at Wide Voltage Range (9–24 VDC): In a multi-camera installation with dozens of switches and injectors, this low footprint keeps the UPS load reasonable and avoids the need for a separate power budget line for switches. The included 90–264 VAC supply means one power cable into the cabinet; the switch adapts to whatever regional voltage standard is in place.
• Voltage Transient Protection on All Signal and Power Lines: Lightning strikes, power surges, and switching transients on industrial sites are real. The solid-state current limiters prevent a shorted camera or a failed injector from bringing down the entire switch or cascading into upstream equipment. This is the insurance you don't think about until it saves your deployment.
• MTBF >100,000 Hours (11+ Years): A statistically low failure rate means you can spec this for five-year or longer surveillance retention windows and not worry about premature replacement. Lifetime warranty covers the whole lifecycle — no end-of-support gotchas.

Deployment Considerations:

• The CNFE5SMS is unmanaged and has no QoS, VLAN, or trunk port logic. If you're mixing camera traffic, voice, and access-control data on one switch and need priority handling for critical streams, move to a managed switch. This is a passive forwarder, and that's intentional.
• Pre-programmed uplink mode assumes a 4-to-1 topology (four input ports feeding one uplink). If your wiring pattern is different — say, three cameras and two data lines — the fixed logic may not match your deployment. Verify the port role before commissioning or request the conformally coated '/C' variant for condensation-prone environments, which adds cost and lead time.

Best fit: multi-camera retail floors, fixed-camera warehouse inventory tracking, and highway or outdoor installations where you need rock-solid uptime and don't want to manage a switch config every time a camera gets swapped. If your site has dynamic topology changes or strict bandwidth isolation, step up to a managed Ethernet network switch instead.
