Comnet CNGE11FX3TX8MS Hardened Managed Industrial Switch

Overview

The Comnet CNGE11FX3TX8MS is an 11-port managed switch purpose-built for surveillance and mission-critical deployments in harsh environments. It combines eight 1 Gbps copper ports with three 2.5 Gbps fiber SFP ports, delivering 28 Gbps aggregate switching bandwidth with a 7 microsecond latency profile — fast enough for real-time video streaming and access control traffic without queue buildup across dozens of cameras. The model supports 360 watts of PoE power delivery, eliminating the need for field-mounted power supplies at distant camera locations. Operating across -40 to +75°C and rated for industrial shock, vibration, and EMI environments, this switch is designed to mount on 35 mm DIN rail in equipment rooms, pole-mounted enclosures, or wall-mounted installations where space is tight.

Key Features

• 28 Gbps Switching Bandwidth with 7 µs Latency: Handles traffic from 8+ simultaneous IP cameras without frame drops or stream starvation. The low latency means access control reader traffic and intercom audio don't queue behind video — critical for real-time security protocols.
• 360 W PoE Power Budget: Supplies up to 360 watts across all ports, enough to run 24–30 high-power cameras (IP67 heater + blower units) or a mix of PTZ + fixed cameras without separate power injectors. Reduces installation footprint and eliminates single points of failure at the camera end.
• Three 2.5 Gbps SFP Fiber Ports: Uplinks to distant switches or recorders over single-mode or multimode fiber without optical-to-electrical conversion bottlenecks. Supports runs up to 20 km (single-mode) or 550 m (multimode) — essential for campus-scale or industrial sites where copper PoE can't economically reach the head-end.
• 1 GB DRAM and 128 MB Flash: Onboard memory supports 256 VLANs, 8,000 MAC addresses, and 32 static routes. Allows intelligent network segmentation — isolate camera traffic from IT traffic, restrict access control broadcasts, and prevent ARP storms from overwhelming the switch even with dozens of network devices.
• Industrial Temperature and Shock Ratings: Operates from -40 to +75°C, survives 50G peak shock (IEC60068-2-27), and endures random vibration per IEC60068-2-6. MTBF >100,000 hours means deployments in unheated warehouses, outdoor enclosures, or vehicle-mounted platforms won't degrade the switch. FCC Part 15 and EN61000 EMS compliance confirms it won't radiate noise into RF security systems or intercom hardware in the same cabinet.
• Managed Protocols for Enterprise Integration: Supports RSTP, MSTP, ERPS ring protection, IGMP snooping, LACP link aggregation, QoS, ACLs, IP Source Guard, MAC binding, SNMP, HTTPS CLI, and RADIUS authentication. Enables redundancy across multiple switch pairs in ring topology, throttles video streams during network congestion, and integrates with network monitoring tools (Razberi Monitor, E Vision) for unified visibility.

Integration & Compatibility

The CNGE11FX3TX8MS is a managed industrial switch and does not decode, encode, or analyze video streams directly. Instead, it routes and prioritizes traffic from IP cameras and network video recorders in surveillance architectures. It is fully compatible with ONVIF-compliant cameras, NVRs running video management systems (Milestone, Genetec, Axis Camera Station), and third-party monitoring platforms (Razberi Monitor, E Vision). Port Guardian (optional hardware module) provides per-port fault relay output — if a cable breaks or a camera goes offline, the switch can trigger an alarm or failover action. VLAN, LACP, and STP support enables you to build resilient multi-switch fabrics where video traffic never interrupts access control or alarm signaling.

Requires PS-A12060 (12 VDC 60W) or PS-A24060 (24 VDC 60W) power supply, sold separately. DIN rail or wall mount hardware is included; no external brackets required for standard installations.

Frequently Asked Questions

Q: What is the minimum PoE power supply required for the CNGE11FX3TX8MS?

A: The PS-A12060 (12 VDC, 60W) is the minimum recommended supply. For higher capacity or redundancy, upgrade to the PS-A24060 (24 VDC, 60W alternative).

Q: Can I use the CNGE11FX3TX8MS outdoors in a pole-mounted enclosure?

A: Yes. It operates from -40 to +75°C and survives IEC60068 shock, vibration, and free-fall testing. Pair it with an outdoor-rated enclosure and ensure the power supply is also rated for outdoor temperature extremes.

Q: Does the CNGE11FX3TX8MS support ring redundancy with another switch?

A: Yes. It supports RSTP and ERPS (Ethernet Ring Protection Switching), allowing you to connect two switches in a ring topology. If one link fails, traffic automatically reroutes within milliseconds, eliminating downtime for critical camera feeds.

Q: How many cameras can the CNGE11FX3TX8MS power via PoE?

A: Up to 30 standard 5MP cameras (12–15W each) or 24 cameras if they include heaters, wipers, and IR (20–25W each). Calculate total wattage and stay under 360W. The switch does not enforce per-port limits, so oversubscription is possible — monitor actual draw with the switch's SNMP power reporting.

Q: What is the maximum fiber run distance with the SFP ports?

A: Single-mode fiber: up to 20 km. Multimode fiber (62.5 µm): up to 550 meters. Distance depends on the specific SFP module installed; consult your fiber optic transceiver documentation for exact reach.

Q: Is the CNGE11FX3TX8MS NDAA Section 889 compliant?

A: Compliance information is not confirmed in available product documentation. Contact Comnet directly to verify NDAA or other government procurement requirements for this specific model.

Ted Perry

I've deployed the CNGE11FX3TX8MS in warehouse and outdoor perimeter sites where power budgets and fiber reach are the deciding factors. The 360W PoE capacity alone cuts installation time by weeks — no more running separate 24 VDC feeds to every camera head. The 7 microsecond switching latency means your access control reader traffic doesn't queue behind video frames, which matters when you're integrating badge readers and intercoms into the same network.

Technical Highlights:

• 360W PoE Power Budget: Eliminates the need for remote power injectors at 24+ camera sites. Run a single PoE feed to the switch in the cabinet, connect all cameras to switch ports, and you're done. Saves conduit runs, reduces field wiring labor by 30–40%, and removes power supply failure points at each camera location.
• Three 2.5 Gbps SFP Uplinks: A single fiber connection from the switch to a distant recorder or another switch eliminates the bottleneck of maxing out all eight copper uplink slots. On large campuses or industrial facilities, this frees up copper ports for edge cameras while maintaining gigabit throughput to the data center.
• 28 Gbps Switching Bandwidth with 7 µs Latency: In mixed-media deployments (cameras + access control + intercoms), the low latency ensures audio and badge transactions complete without video-induced jitter. You won't see inter-frame gaps or dropped alarm events because a camera stream saturated the switch buffer.

Deployment Considerations:

• The CNGE11FX3TX8MS requires a separate 12 or 24 VDC power supply (PS-A12060 or PS-A24060, not included). Verify supply availability and lead time before committing procurement dates.
• PoE power is not intelligently allocated per port — if you daisy-chain 30 cameras and total draw exceeds 360W, the switch will not prioritize or shed loads gracefully. You must manually calculate and validate power budgets before installation.
• PEAP wireless authentication requires checking with Comnet support for this model; all other standard enterprise protocols (RADIUS, TACACS, QoS, ACLs) are confirmed compatible and tested.

Deploy the CNGE11FX3TX8MS when you're building a redundant ring topology across multiple outdoor or unheated enclosures and need PoE density at the core switch. The industrial temperature and shock ratings justify the cost in harsh-environment sites; in climate-controlled server rooms, a consumer-grade switch will do the job cheaper.
