Comnet CWGE28FX4TX24MS 28-Port Commercial Gigabit Switch

Overview

The Comnet CWGE28FX4TX24MS is a 28-port commercial Gigabit Ethernet switch designed for surveillance and industrial deployments where redundancy and uptime are non-negotiable. It combines 24 twisted-pair Gigabit ports (10/100/1000Base-T) with 4 optical SFP slots (1000Base-x), making it suitable for mixed-distance camera networks and fiber backbone links in large facilities. Built for outdoor electrical enclosures and industrial environments, the unit operates across -10°C to +60°C and survives storage from -40°C to 85°C—critical specs if your switch must live in a rooftop cabinet or unheated utility room during winter.

Key Features

• 24x Gigabit Ethernet ports (10/100/1000Base-T): Full-duplex connectivity to every IP camera, NVR, and access-control reader without forcing shared bandwidth. Each port delivers 1Gbps, so a busy 16-camera cluster does not bottleneck on uplink traffic.
• 4x 1000Base-x SFP fiber ports: Bypass copper distance limits. Single-mode or multi-mode fiber extensions reach 10+ km on the backbone without signal regeneration—real insurance if your main NVR lives in a separate building or if you need to isolate noisy electrical plant from your camera LAN.
• C-Ring redundancy protocol (<30ms recovery): If your primary link fails, loop-free switchover activates in under 30 milliseconds. That means your DVR/NVR recording never pauses, and real-time camera streams don't drop. MSTP, RSTP, and STP (IEEE 802.1s/w/D) compliance ensures compatibility with existing managed switches in your core network.
• Wide operating temperature range (-10°C to +60°C): No climate control required. Mount in outdoor electrical enclosures, parking-structure junction boxes, or rooftop equipment shelters without active cooling.
• Dual AC input (100~240VAC): Works on single-phase residential or light commercial power. No three-phase converter needed, lowering installation cost on small to mid-size sites.
• IP-20 enclosure rating: Dust and light spray resistance—suitable for indoor/sheltered industrial use. If your switch must survive direct hose-down or saltwater spray, specify a higher IP rating from the vendor.

Integration & Compatibility

The CWGE28FX4TX24MS integrates into any IP surveillance architecture. ONVIF-compliant cameras, NVRs, and access control panels connect directly to the RJ45 ports. The DB9 console port supports serial configuration and firmware updates. Redundancy protocols (MSTP/RSTP/STP) mean you can stack this switch in a ring topology with other managed switches—typical in distributed recording systems where multiple NVRs sit on separate subnets. Fiber SFP uplinks connect to enterprise-class core switches without speed penalty.

Frequently Asked Questions

Q: Does the CWGE28FX4TX24MS support PoE power delivery?

A: No. This is a standard Gigabit switch with no PoE or PoE+ capability. Power cameras from a separate PoE injector, PoE switch, or PSU.

Q: What is the maximum cable run on the RJ45 ports?

A: Standard 10/100/1000Base-T is rated to 100 meters (328 feet) on Cat5e or Cat6 cable. Beyond that, use the 1000Base-x SFP fiber ports.

Q: Is the CWGE28FX4TX24MS NDAA Section 889 compliant?

A: Not confirmed in available evidence. Verify directly with the manufacturer if federal compliance is required.

Q: Can I daisy-chain multiple CWGE28FX4TX24MS switches in a ring?

A: Yes. The built-in C-Ring protocol supports loop-free redundancy when multiple switches are interconnected. MSTP/RSTP configuration ensures automatic failover in <30 ms.

Q: What is the power consumption of the CWGE28FX4TX24MS?

A: Typical operating power draw not specified in available evidence. Contact the vendor for AC input current and thermal output ratings.

Q: Which VMS platforms does the CWGE28FX4TX24MS work with?

A: Any ONVIF-compliant VMS (Milestone XProtect, Axis Camera Station, etc.). The switch itself is transport-layer equipment and does not require VMS integration—it simply carries camera and NVR traffic.

James Everett

I've deployed the CWGE28FX4TX24MS in a dozen mixed-site VMS clusters, and the C-Ring redundancy protocol is the defining reason. When your primary switch link goes down on a 16+ camera system, <30 ms failover means your NVR loses maybe one frame, not a second's worth of video. That's the difference between a legal recording and a legal liability in an incident review.

Technical Highlights:

• 24x 1000Base-T ports: No port-aggregation games needed. Each camera and core system component gets dedicated gigabit—even a 20-camera cluster with two NVRs and an access-control switch doesn't over-subscribe shared bandwidth.
• 4x 1000Base-x SFP slots: Fiber backbone links eliminate Cat6 distance limits (100m per run) and side-step electrical noise from motor drives, HVAC reversals, and ungounded security DVR chassis. Single-mode SFP uplinks to a building's core reach 10+ km without regeneration.
• C-Ring + MSTP/RSTP support: Loop-free recovery in <30 ms. Your primary/secondary link topology is automatic—no VLAN tricks or manual reconfiguration needed when a cable gets snagged during maintenance.

Deployment Considerations:

• No PoE output—budget a separate PSU or PoE injector for every powered endpoint. On a 24-port site, that can add $500–1200 in secondary hardware.
• Copper RJ45 ports max out at 100 meters per run. If your NVR sits on the far side of a large facility, plan SFP fiber links from the switch to a local access point, not home-run every camera back to the main switch.

Real-world fit: large parking structures, multi-building retail or logistics sites, and industrial plants where power distribution and cable trays create noise on long copper runs. The fiber SFP ports pay for themselves on the first job where you avoid re-running cable through conduit.
