Comnet Hardened 2 FX SFP 100/1000Mbps FX + 4 Port 10/100Mbps TX Ports Managed - CNGE6FX2TX4MSP

Comnet CNGE6FX2TX4MSP Hardened PoE+ Managed Switch

Overview

The Comnet CNGE6FX2TX4MSP is an industrial L2+ managed switch built for surveillance and outdoor PoE networks where reliability and power delivery trump commodity features. Four gigabit copper ports each deliver up to 30W via IEEE 802.3at PoE+, and a total 120W system budget lets you power multiple cameras, access points, or VoIP phones without separate power infrastructure. Two SFP fiber slots add redundancy and long-distance backbone connectivity — dual fiber ring topologies recover from network breaks in seconds. Housed in aluminum with IP30 protection and rated for -40°C to 75°C operation, the CNGE6FX2TX4MSP handles temperature swings and electrical noise that would kill standard datacom gear.

Key Features

• 120W Total PoE+ Budget (30W per port): Four copper ports each supply IEEE 802.3at PoE+ at 30W maximum — enough for high-power 5MP+ cameras, pan-tilt-zooms, or dual-radio APs. Total 120W means you can run four cameras simultaneously without oversubscription or manual power gating. Skip the external injectors and conduit runs; power follows the network cable.
• Intelligent Power Management: User-configurable power budgets prevent runaway consumption if a device fails or draws unexpectedly; PoE alive-checking packets verify each powered device is responsive; hourly/weekly power scheduling lets you disable feeds during off-hours (night shutdown for cameras, weekend APs). Cuts waste and reduces management burden in 24/7 operations.
• Dual SFP Gigabit Fiber Slots: Two GbE SFP interfaces enable fiber daisy-chain and ring topologies — no VLAN trunking complexity, just plug two fiber SFP modules and loop the ring. Fiber eliminates ground loops in long runs and survives electrical strikes; if one fiber link fails, ring healing re-routes traffic within milliseconds. Real uptime gain for critical perimeter and campus networks.
• IP30 Aluminum Enclosure with Multi-Layer Protection: ESD, surge, overcurrent, reverse-polarity, and short-circuit protection — not marketing noise, but essential in outdoor cabinets and electrical-noisy environments (loading docks, parking structures, near switchgear). Aluminum dissipates heat in dense mount scenarios better than plastic.
• L2+ Managed Features (SNMP, RMON, QoS, IGMP Snooping): Monitor port statistics and traffic in real time via SNMP; multicast filtering prevents unnecessary video flood on trunk ports; QoS queuing ensures critical traffic (alarms, management) doesn't starve behind bulk video. Not plug-and-play simple, but non-negotiable for networks with 10+ cameras.
• 12 Gbps Switch Fabric, 11.9 Mpps Forwarding: Six ports all connected to shared fabric means zero blocking — 4 x 1000Mbps copper + 2 x 1000Mbps SFP can saturate simultaneously without packet loss. 8K MAC table holds dynamic addresses for mid-scale networks; 4K active VLANs segment IoT, guest, and staff traffic without reconfiguration.
• Industrial Temperature Range -40°C to 75°C: HVAC-free outdoor cabinets in northern climates, shipping yards, and unheated storage areas stay online where consumer switches freeze or thermally throttle. No derating down to the -20°C floor — full PoE power at -40°C is a real advantage for winter commuter parking and rural gate cameras.
• DIN-Rail Mount, 740g Aluminum Chassis: Fits standard industrial enclosures and IP rated outdoor boxes without custom brackets. 50 x 160 x 120 mm footprint consumes minimal panel real estate; low weight means no heavy-duty rail reinforcement needed.

Integration & Compatibility

The CNGE6FX2TX4MSP works with any ONVIF-compliant camera, NVR, or access control system. Fiber SFP slots accept standard GbE transceivers (Comnet's CWGE series, or any vendor's LC-connector SFP modules). Jumbo frame support (10K bytes) improves throughput for video-heavy backhaul. One relay output (1A @ 24V DC) can trigger an external alarm or integrate with building automation for network-down events. For VMS: Milestone Xprotect, Axis Camera Station, and firmware-centric systems (Uniview, Hikvision) integrate via ONVIF and SNMP; no proprietary drivers required.

Environmental and Power Considerations

Input voltage range 48–57 VDC accommodates UPS outputs and industrial power supplies without regulation failure. System power consumption is just 10W idle, so a 60W PoE power brick handles standby and low-load periods; under full 120W draw, you need a dedicated 150W or larger supply. Operating humidity spec (5–95% RH) and storage range (-40°C to 85°C) reflect true industrial duty; keep condensation-prone outdoor cabinets vented or use dessicant cartridges on cable entries.

When to Choose a Different Model

If your site runs purely copper Gigabit (no fiber), a smaller non-managed PoE switch saves cost and rack space. If you need PoE++ (802.3bt, 95W+) for emerging ultra-high-power cameras or multi-element APs, step up to models in the Comnet hardened line that support Class 6–8 delivery. For remote power sourcing over extremely long distances (500+ meters), combine the CNGE6FX2TX4MSP with passive PoE extender modules on the far end.

Frequently Asked Questions

Q: What is the warranty on the Comnet CNGE6FX2TX4MSP?

A: Warranty details are not included in the available technical documentation. Contact the vendor directly for coverage and duration.

Q: Can the CNGE6FX2TX4MSP power four 5MP cameras simultaneously?

A: Yes. The switch provides 30W per port on each of the four copper PoE+ ports, for a total 120W budget. Most 5MP IP cameras draw 10–15W; the CNGE6FX2TX4MSP can power four cameras with headroom for ambient heaters or optical zoom.

Q: Does the CNGE6FX2TX4MSP support ring redundancy?

A: Yes. The two SFP fiber ports support dual fiber ring topologies. If one fiber link breaks, traffic automatically reroutes through the other fiber link with minimal reconvergence time — ideal for mission-critical camera backhaul.

Q: What SFP modules does the CNGE6FX2TX4MSP accept?

A: The switch accepts standard 1000BASE-FX (multimode or single-mode) GbE SFP modules with LC connectors. Comnet manufactures compatible fiber SFP transceivers; third-party SFP modules from mainstream vendors (Cisco, Juniper-compatible aftermarket) are typically compatible but verify with your supplier before purchase.

Q: What is the typical PoE power loss over cable runs longer than 100 meters?

A: IEEE 802.3at PoE is rated to 100 meters of Cat5e or better cabling without special compensation. Beyond 100 meters, voltage drop increases; some powered devices may not accept power or may operate at reduced capability. For distances over 100 meters, use a PoE extender or secondary injector on the far end.

Q: Does the CNGE6FX2TX4MSP integrate with Milestone Xprotect or Axis Camera Station?

A: Yes. The switch is ONVIF-compliant and supports SNMP for network management and monitoring. Both Milestone and Axis systems can query the switch's MIB for port statistics and power status via standard protocols; cameras and recorders connected to the switch ports work normally without special configuration.

The CNGE6FX2TX4MSP delivers something you don't see in consumer or low-tier managed switches: real industrial ruggedness married to 120W PoE+ delivery and fiber ring support. The 30W per-port budget is table stakes for modern surveillance, but the total 120W envelope and intelligent power budgeting mean you can architect networks without second-guessing power math on every port. And the dual SFP fiber interface — that's the architecture multiplier most integrators sleep on until a lightning strike or ground loop wipes out a 40-camera system.

Technical Highlights:

• 120W Total PoE+ at 30W per Port: Four copper ports deliver enough wattage to run 5MP+ cameras with PTZ and heated housings without oversubscription. The system power budget is honest — you can run all four ports at max load simultaneously without port throttling or watchdog resets. When you're installing in a -40°C climate, you need heater current; this switch doesn't de-rate at temperature extremes like datacom gear does.
• Dual SFP Gigabit Fiber Slots with Ring Support: Fiber daisy-chain collapses cable count and eliminates ground loops in long backbone runs. Ring topology (one fiber loop through two SFP ports) converges network failures in milliseconds — no RSTP recalculation, just hardware ring healing. If your main camera backhaul spans a parking lot or campus, this is the topology that keeps uptime honest.
• IP30 Aluminum + 7-Layer Protection (ESD, Surge, OCP, Reverse Polarity, Short Circuit): Industrial cabinets are electrical hot zones — refrigerated trailers, loading dock junction boxes, outdoor pole mounts near switchgear. The CNGE6FX2TX4MSP doesn't just survive transients; it has separate protection circuits for each failure mode. Surge spikes that would blue-smoke a datacom switch just trigger the protection threshold and keep the switch live.
• -40°C to 75°C Operating Range with No Power De-Rating: Full 120W PoE delivery holds across the entire temperature envelope. Competitive switches either can't source full power below -20°C, or they thermally throttle above 60°C; the CNGE6FX2TX4MSP doesn't compromise. If your camera network spans an unheated warehouse and a sun-baked parking structure, you don't burn contingency on temperature variability.
• L2+ Management with SNMP, QoS, IGMP Snooping: You can configure per-port power limits, schedule power on/off by hour or day (power down night cameras), and filter multicast video to prevent broadcast storms on high-count deployments. For 10+ cameras, this is not luxury — it's how you prevent one misbehaving device from taking down the whole segment.

Deployment Considerations:

• Input voltage range is 48–57 VDC, which works with most 48V industrial UPS and power supply systems, but if your cabinet is powered by a 24V rail, you'll need a separate 48V supply or a DC-to-DC converter module.
• The 120W total budget includes all four ports plus the switch's 10W idle draw. Under full load (four ports at 30W each = 120W), you need a power supply rated for at least 150W to stay out of saturation; a 60W supply won't sustain the CNGE6FX2TX4MSP if all four cameras max out in the same second.
• IP30 protection means the aluminum chassis resists dust and splashing but won't survive full submersion or high-pressure washdowns. If the switch sits in a true outdoor enclosure, ensure the cabinet itself carries IP66 or IP67; the switch is the electronics layer, not the weatherproof boundary.

Position the CNGE6FX2TX4MSP for multi-camera outdoor and industrial networks — parking lots, campus backbones, long-distance camera strings, and cold-climate installs where standard datacom switches fail. The fiber ring topology and industrial protection stack make it the right choice when uptime matters more than per-unit cost.
