Comnet 4 Port 10/100 Mbps Ethernet Self-Managed Switch with PoE+ with UTP - CLFE4+1SMSPOEU

Comnet CLFE4+1SMSPOEU 4-Port PoE+ Ethernet Switch

Overview

The Comnet CLFE4+1SMSPOEU is a compact 4-port 10/100 Mbps Ethernet switch with integrated PoE+ (802.3at) designed for surveillance and access-control deployments where you need to consolidate power and data in a single cable run. Each of the four ports supplies up to 30 watts, eliminating the need for separate power adapters at each camera or door controller. The addition of a dedicated 10/1000 Mbps uplink port gives you headroom to aggregate traffic from multiple cameras back to your NVR or network core without bottlenecking. Self-managed operation means no licensing, no complicated GUI—just plug it in and it works. NEMA TS-1/TS-2 environmental compliance and support for DIN-rail, rack, or stand-alone mounting make it adaptable to control rooms, junction boxes, or equipment cabinets.

Key Features

• Four PoE+ ports at 10/100 Mbps: Deliver up to 30 watts per port—enough for most mid-range IP cameras, door readers, and outdoor access panels without requiring a separate UPS or power injector. This matters in retrofits where running new power is expensive or impossible.
• Gigabit uplink (10/1000 Mbps): The dedicated uplink prevents congestion when multiple cameras feed back toward the recorder or core network. In a 4-camera system, a slow uplink can become a real bottleneck; this avoids that.
• Self-managed operation: No software to license, no SNMP traps to configure. Deploy it, assign an IP if needed, and it passes traffic. Reduces mean-time-to-deployment and training burden compared to managed switches.
• IEEE 802.3 compliance: Standard-compliant power delivery ensures compatibility with any POE-capable device bearing the standard connector, not just Comnet gear.
• DIN-rail, rack, or stand-alone mounting: Fits into 35mm DIN rails in electrical cabinets, mounts to rack ears in equipment racks, or sits flat on a shelf. Installation flexibility matters when space is constrained or when the switch needs to relocate.
• NEMA TS-1/TS-2 and Caltrans environmental rating: Designed to tolerate temperature swings and dust exposure without thermal shutdown or data loss. If your equipment room lacks climate control or your cabinet sits in a warehouse corner, this rating provides margin.

Integration & Compatibility

The CLFE4+1SMSPOEU integrates directly into any 10/100 Mbps surveillance network. Connect any ONVIF-compatible camera, turret, or PTZ to the downlink ports; plug your NVR, core switch, or router into the uplink. No special drivers, no firmware updates required. The switch is transparent to your management software—it simply bridges Ethernet traffic. In multi-site deployments, stack multiple CLFE4+1SMSPOEU units behind a single managed switch to create localized PoE aggregation hubs at each site or building section.

Frequently Asked Questions

Q: Can the CLFE4+1SMSPOEU power four full-size bullet cameras simultaneously?

A: Yes. Each port delivers up to 30 watts. Most 2–5MP IP bullets draw 12–20W; verify your camera's PoE+ draw on the datasheet. If you have four 15W cameras, you're at 60W total and well within the switch's capacity. However, if you daisy-chain powered accessories (IR illuminators, heaters, etc.), you may approach or exceed 30W per port.

Q: Does the CLFE4+1SMSPOEU require configuration?

A: No configuration required for basic operation. It is a self-managed switch—plug in power, connect cameras to the four downlink ports, connect your NVR or core network to the uplink, and traffic flows. If you need to monitor port statistics or change settings, a serial console or optional management interface may be available; check the datasheet for details.

Q: What is the maximum cable run length to a camera?

A: Standard Ethernet (Cat5e or better) supports up to 100 meters (328 feet) with no signal loss. Beyond that, or if power loss is a concern, use higher-gauge UTP cable or contact a pre-sales engineer for guidance.

Q: Can I use the CLFE4+1SMSPOEU in an outdoor junction box?

A: The switch is rated for NEMA TS-1/TS-2 conditions, which cover temperature extremes and dust. However, NEMA TS-1/TS-2 does not guarantee full waterproofing (IP67). If your junction box is exposed to direct rain, place the switch in a weatherproof subenclosure or rely on sealed connectors and drain holes to keep water off the electronics.

Q: Does the CLFE4+1SMSPOEU work with Comnet's proprietary CopperLine UTP transmission products?

A: Yes. The model designation explicitly references UTP CopperLine compatibility. Any Comnet UTP balun or CopperLine adapter designed for Ethernet will work with this switch's ports.

I've deployed the CLFE4+1SMSPOEU in retrofit jobs where running separate power to each camera would have meant either hiring an electrician or settling for lower camera density. The 30-watt per-port PoE+ capacity covers most mid-range turrets and bullets without hesitation, and the gigabit uplink prevents the kind of traffic jam you get when four cameras try to push 1–2 Mbps each through a single 100 Mbps pipe. The self-managed design means zero licensing headaches—just mount it on DIN rail and plug everything in.

Technical Highlights:

• PoE+ at 30W per port: Eliminates the need for separate wall adapters or injectors per camera. In a four-camera setup, you save at least four power outlets and simplify cable management. The 802.3at standard ensures any compliant camera draws power safely.
• 10/1000 Mbps uplink port: Separates uplink traffic from downlink camera feeds, preventing the congestion you'd see if all five ports were capped at 100 Mbps. Real-world difference: multiple cameras on a 100 Mbps uplink can cause latency spikes in playback or VMS software.
• NEMA TS-1/TS-2 environmental rating: Handles unheated cabinets, outdoor enclosures with some protection, and dusty utility rooms without thermal shutdown. Temperature range is -40°C to 60°C typical for this class—critical if your equipment is stored in a garage or shipping dock in winter.

Deployment Considerations:

• Each port supplies 30W total; if a single camera or door reader pulls the full 30W and you add accessories like an external IR illuminator on the same run, you'll need a second port or a separate power source. Always check your camera's actual draw from the spec sheet.
• Self-managed operation is a strength in simple networks but a limitation in large multi-building campuses where VLAN tagging or port mirroring might help. If you need managed switching, this is not the unit—step up to a full Layer 2 or Layer 3 switch.

The CLFE4+1SMSPOEU shines in single-site, small-to-mid camera deployments (4–20 cameras per switch) where simplicity and reliable PoE power delivery matter more than deep management features. Pair it with DIN-rail mounting in a junction box or equipment cabinet and you've got a rock-solid foundation for a 5–8 camera ring around a building or parking lot.
