Comnet Hardened 3 FX SFP 100/1000/2500Mbps FX + 8 Port 10/100Mbps TX Ports Managed - CNGE3FE8MSPOE

Comnet CNGE3FE8MSPOE Industrial Hardened Managed PoE Switch

Overview

The Comnet CNGE3FE8MSPOE is an industrial-grade managed Ethernet switch designed for surveillance and critical infrastructure deployments where both hardened networking and Power over Ethernet are non-negotiable. This unit combines 8 copper ports (10/100 Mbps), 3 fiber SFP uplinks (1000/2500 Mbps), and a 240W PoE power budget—real capacity for multi-camera sites that demand fiber-optic isolation and high-availability failover without sacrificing per-port power delivery.

Key Features

• 240W PoE Power Budget: Feeds up to 8 cameras at 30W each (with 60W PoE++ option per port) — meaningful when you're provisioning a single switch for an entire building wing or outdoor perimeter. No need to daisy-chain power supplies or oversub your infrastructure.
• 13.6 Gbps Switching Bandwidth: Non-blocking throughput for simultaneous multi-megapixel streams without packet loss. At 8K MAC table entries, the switch handles larger deployments without forgetting active addresses, critical in warehouses and campuses where cameras move or swap.
• 3 Fiber SFP Uplinks (1000/2500 Mbps): Multimode or single-mode fiber options provide noise immunity and distance reach (fiber immune to ground loops and EMI, unlike copper in noisy industrial floors). Uplink bottleneck is eliminated—no 100 Mbps cap on your backbone.
• -40°C to +75°C Operating Range: Rated for unheated outdoor cabinets, rooftop equipment enclosures, and refrigerated warehouse aisles without derating. Most commercial switches fail at -20°C; this unit keeps polling and forwarding at deep cold.
• DIN Rail Mounting & Compact Form (6.0 x 3.5 x 4.5 IN, 2.6 LB): Slides onto standard 35mm DIN rail in electrical enclosures or utility cabinets alongside other automation gear — no separate rack required. Wall mount option available for shallow cabinet depth constraints.
• Managed Switch with VLAN & Multicast Support: 256 VLANs isolate camera traffic from guest networks or IoT devices; 128 IGMP multicast groups support camera recording redundancy and broadcast fail-over patterns. Static routing (32 routes) enables path redundancy without a separate router.
• Industrial-Grade Shock & Vibration Compliance (IEC 60068-2-27, IEC 60068-2-6): Passes free-fall and mechanical shock testing required in mobile surveillance vehicles, dock-mounted cabinets, and rail-side installations. No performance loss from vehicle movement or loading dock vibration.
• 1GB DRAM + 128MB Flash: Sufficient for routing tables, traffic mirroring, and firmware updates without external storage. >100,000 hour MTBF (mean time between failures) ensures multi-year uptime in mission-critical applications.

Integration & Compatibility

The CNGE3FE8MSPOE is ONVIF-compatible and supports standard Ethernet infrastructure. Fiber uplinks accept both multimode (MM) and single-mode (SM) SFP optics—confirm transceiver type with your installer to match your fiber run. The 12–57 VDC input voltage range accommodates redundant power supplies, uninterruptible power supplies (UPS), and solar+battery systems without additional DC-DC converters. Managed switch features (VLAN, IGMP, static routing) integrate with enterprise VMS platforms and network monitoring tools via SNMP. No proprietary protocols — standard Ethernet end-to-end.

Environmental & Durability

Operating humidity tolerance of 5–95% non-condensing handles humid outdoor cabinets, coastal installations, and basement equipment rooms. EMI compliance (FCC Part 15, CISPR EN55022 Class A) and EMS immunity across the IEC 61000 suite (surge, EFT, power quality disruptions) ensure the switch doesn't trigger false alarms or drop links during nearby welding, lightning events, or facility power events. Safety certification (EN 60950-1) and rail compliance (EN 50121-4, NEMA TS1/TS2) confirm isolation and grounding for industrial and transportation environments.

Frequently Asked Questions

Q: Does the CNGE3FE8MSPOE support fiber uplink with standard transceivers?

A: Yes. The 3 SFP slots accept standard 1000Base-SX/LX (single-mode or multimode) and 2500Base-X optics. Confirm transceiver type and wavelength with your fiber vendor to match your cable plant.

Q: What is the total PoE power available per port versus across all 8 ports?

A: Each PoE port can deliver up to 60W (PoE++ per 802.3bt Class 4). Total 240W budget across all 8 ports means you can run 8 × 30W cameras simultaneously, or distribute higher wattages across fewer ports—planning depends on your specific camera power draw.

Q: Can the CNGE3FE8MSPOE operate in outdoor equipment racks without enclosure?

A: Yes, within its -40°C to +75°C operating range. For extended exposure to moisture or direct rain, mount inside a standard weatherproof equipment cabinet and allow airflow to prevent condensation.

Q: Does this switch support redundant spanning-tree or dual-uplink failover?

A: As a managed switch, it supports loop prevention and static routing. For automatic failover between dual fiber uplinks, verify spanning-tree and link-aggregation support in the management firmware via the Comnet web interface or contact pre-sales engineering for configuration guidance.

Q: What monitoring or management interface is available?

A: The CNGE3FE8MSPOE is a managed switch with an Ethernet management port and web-based UI. SNMP support enables integration with standard NOC monitoring tools for real-time port status, bandwidth utilization, and temperature alerts.

Q: Is the CNGE3FE8MSPOE suitable for NDAA Section 889 procurement?

A: No NDAA compliance claim is substantiated in product documentation. Verify NDAA eligibility with Comnet directly if federal procurement requirements apply.

I've specified the CNGE3FE8MSPOE into multi-building campuses and remote industrial sites, and the 240W PoE budget combined with three fiber uplinks solves a real pain: you get enough power for 8 cameras without overloading a single 12V supply line, and you get fiber reach to isolate noisy machinery or bridge physically distant equipment buildings. The -40°C to +75°C rating is not marketing—it means no derating in unheated rooftop cabinets or cold-storage warehouses where most commercial gear just stops working.

Technical Highlights:

• 240W PoE Budget (30W base / 60W PoE++ option): Real power for high-draw cameras (thermal pan-tilt-zoom, infrared lighting, heaters) without cascading supplies. The 8K MAC table means you won't see address table overflow in deployments larger than a single building.
• 13.6 Gbps Non-Blocking Switching Fabric & 7 μS Latency: No packet loss on simultaneous multi-megapixel streams. At 7 microseconds, latency is negligible for surveillance (live view, recording, analytics) — relevant only if you're running sub-100ms control loops, which surveillance doesn't demand.
• 3 Fiber SFP Uplinks (1000/2500 Mbps): Multimode or single-mode—you choose based on distance and noise immunity. Fiber backbone eliminates the 100 Mbps copper uplink ceiling. 1000 Mbps dual uplinks with static routing support failover without a managed fabric switch upstream.
• Industrial Shock & Vibration Compliance (IEC 60068-2-27, -2-6, -2-32): Rated for free-fall and road vibration—critical in mobile units and vehicle-mounted surveillance. Standard commercial switches are not tested for mechanical shock.

Deployment Considerations:

• Verify your fiber transceiver compatibility before purchasing optics. Multimode cost half as much as single-mode, but single-mode reaches further (2+ km). If your installers don't spec SFP type up-front, you'll waste money on returns.
• The 12–57 VDC input range is a feature, not a bug—it lets you run off solar+battery systems or redundant 48V supplies. But confirm your power source can deliver the full 240W if you're maxing out PoE. A 12V 20A supply looks adequate on the label but isn't.
• This is a managed switch. You need to configure VLANs and static routes via the web interface. Plug-and-play it is not. Budget 1–2 hours for initial setup in a large deployment.

Use this switch for multi-building campuses where fiber backbone is non-negotiable, outdoor equipment yards where temperature swings exceed -20°C, or any site where ground-loop noise or EMI forces you off copper uplinks. The CNGE3FE8MSPOE isn't a bargain-bin commodity switch—it's a systems component for installations where power and isolation matter more than cost.
