Comnet Hardened Managed Ethernet Switch 2 SFP 8 RJ45 Ports with 90 Watt PoE - CNGE10FX2TX8MSBT

Comnet CNGE10FX2TX8MSBT Hardened Managed Ethernet Switch

Overview

The Comnet CNGE10FX2TX8MSBT is a hardened managed switch purpose-built for video surveillance and industrial automation networks where temperature extremes, vibration, and electrical noise are the default. Eight 1GbE RJ-45 ports deliver 90 watts of PoE power — enough to run multiple high-power cameras simultaneously — while two 2.5G SFP uplinks handle fiber backbone transport without bottleneck. Rated for -40 to +70°C operation and EMC-hardened per EN50121-4 railway and NEMA TS2 traffic standards, this is the switch you deploy in outdoor headend shelters, moving vehicle gateway cabinets, and remote telemetry nodes where commercial networking gear fails.

Key Features

• 90-Watt PoE Budget (IEEE 802.3bt): Run 7–9 high-current cameras without auxiliary power injection. At typical mixed loads (turrets at 40W, domes at 20W), the budget stretches further; you avoid the complexity and cost of separate injectors or stackable PoE modules.
• 8 x 10/100/1000Base-Tx Copper Ports: Full gigabit speed on every copper port keeps inter-camera latency flat. No port-based congestion in 24/7 recording scenarios — each stream gets consistent throughput.
• 2 x 100/1000/2.5G SFP Fiber Uplinks: Single-mode or multi-mode fiber reach 1–2 km without electrical noise pickup — critical in industrial zones with high-frequency noise, AC motor farms, or railway electrification. Dual SFP enables ring topology for automatic link failover.
• 28 Gbps Switching Bandwidth, 7 μS Latency: Non-blocking fabric handles full-wire-rate traffic across all ports simultaneously. Sub-microsecond latency matters for synchronized multi-camera triggers and fast packet processing in edge analytics. No queuing delay visible to your VMS.
• 4096 VLANs and 8K MAC Table: Segment camera traffic by zone (front building, rear lot, vehicle barrier) without external VLAN tagging on each camera. Large MAC table prevents address cache overflow on large deployments (50+ cameras per switch).
• 9.6K Jumbo Frame Support: Allows larger IP packets, reducing CPU overhead on the switch and attached edge devices. Useful for high-bitrate H.265 streams from multi-sensor rigs.
• Industrial Temperature and Shock Rating: Storage rated -40 to +85°C; operating -40 to +70°C. Survives -40°C alpine sites and +70°C sealed outdoor cabinets without derating. Shock (IEC60068-2-27) and free-fall (IEC60068-2-32) compliance covers vibrating vehicle mounts and rough-handling logistics.
• DIN-Rail or Wall Mount: Vertical DIN-rail installation saves panel real estate in compact shelters. Wall mount works for shallow outdoor junction boxes.
• FCC, ICES-003, CISPR 32 Class A, EN55035 EMC Compliance: Designed to tolerate and not radiate high-frequency noise typical of surveillance sites near power lines, radio transmitters, or welding equipment.
• Low Idle Power (<13W), High PoE Load (750W max input): Minimal overhead when PoE budget is unused; scales to full load without thermal throttling. Requires external 52–57 VDC PSU (minimum PS-A48060; redundant pair PS-A48500 recommended).

Integration & Compatibility

The CNGE10FX2TX8MSBT is a standards-based Layer 2/3 managed switch. It speaks SNMP (v1/v2c/v3) for monitoring, supports port mirroring for passive analytics feeds, and delivers VLAN isolation for multi-tenant or multi-site camera groups. Any ONVIF-compliant camera or edge box (NVR, video analytics appliance) integrates without firmware customization. Paired with redundant external 48 VDC supplies, the switch powers a small to mid-size surveillance node (8–12 cameras) without a dedicated UPS if you engineer the battery hold-up time into your PSU selection.

Frequently Asked Questions

Q: Does the CNGE10FX2TX8MSBT support ring topology for automatic failover?

A: Yes. The dual SFP uplinks and managed switch capabilities support Rapid Spanning Tree Protocol (RSTP) and other ring-protection protocols. Configure two fiber paths to your core switch; the CNGE10FX2TX8MSBT automatically blocks one port until the active link fails, then converges in milliseconds.

Q: What external power supply do I need?

A: Minimum: Comnet PS-A48060 (48 VDC). For redundancy and sustained high PoE load: pair of PS-A48500 (48 VDC, higher capacity). Power input is 52–57 VDC nominal.

Q: Can I run this switch at -40°C?

A: Yes. Operating temperature is -40 to +70°C. Below 0°C, allow a warm-up period before applying high PoE load; cold components draw higher inrush current. Alpine and polar sites require external heat tape or insulation on the power supply.

Q: Is the CNGE10FX2TX8MSBT NEMA TS2 compliant?

A: Yes. NEMA TS2 and EN50121-4 (railway) certifications confirm suitability for traffic signal vaults, highway cabinets, and rail-mounted enclosures.

Q: How many cameras can the 90W PoE budget support?

A: Depends on per-camera draw. Typical PTZ dome: 40W. Fixed turret: 20W. Mixed load example: four 20W domes (80W) leaves 10W headroom; eight 10W domes fill the budget exactly. Always check your specific camera datasheets and de-rate for cable loss over long runs.

Q: Does the switch support VLAN segmentation for multi-site networks?

A: Yes. 4096 VLAN support lets you isolate camera traffic by building, zone, or customer tenant without external tagging hardware. Configure per port via management interface.

Eden Phillips

I've deployed the CNGE10FX2TX8MSBT in roadside surveillance nodes and outdoor rail yards where commercial switches don't survive the first winter. The 90W PoE budget and dual 2.5G SFP uplinks mean you're not fighting bandwidth or power headroom when you scale from 4 cameras to 8. The -40 to +70°C spec isn't marketing fluff — I've watched standard enterprise gear shut down or reboot in unheated shelters; this unit keeps running.

Technical Highlights:

• 28 Gbps switching fabric + 7 μS latency: Full-rate non-blocking throughput ensures every camera stream reaches your NVR or edge analytics box without queuing delay. Critical for synchronized multi-camera playback and fast motion detection triggers across zones.
• IEEE 802.3bt (90W) PoE on 8 ports: Four high-current PTZ domes (40W each) or eight mid-range turrets (20W each) draw directly from the switch. No auxiliary injectors cluttering your cabinet.
• 4096 VLANs + 8K MAC table: Segment your 8-camera site into perimeter, interior, and administrative traffic without replicating packets. Prevents address exhaustion if you ever stack switches or add edge boxes downstream.
• EN50121-4 railway + NEMA TS2 compliance: EMC and mechanical hardening verified for high-noise industrial zones. Not just tested — certified for electrified rail and highway environments.

Deployment Considerations:

• You must source an external 52–57 VDC power supply (minimum PS-A48060; dual PS-A48500 for redundancy). The switch itself pulls under 13W idle, but PoE budget is separate — budget accordingly in your 48 VDC rails.
• Cold-start power. Below 0°C, capacitive inrush on the PoE rails can spike. If you're in alpine or arctic deployments, soft-start the switch or pre-warm it with heat tape before PoE load hits. No surprises if you plan it.
• Fiber uplinks are optional but recommended. If your core is more than ~100 meters away over dirty copper (EMI-prone sites), fiber shuts down noise coupling in one step.

Right tool for remote headend consolidation, vehicle gateway cabinets, and outdoor rail surveillance. Overkill for a cozy indoor data center; perfect for anywhere else.
