Comnet CNGE11FX3TX8MSPOEHO Hardened Industrial Managed Switch

Overview

The Comnet CNGE11FX3TX8MSPOEHO is an 11-port managed industrial switch purpose-built for surveillance and remote infrastructure deployments where reliability matters more than form factor. You get 8 copper RJ45 ports (all PoE-capable), 3 SFP fiber ports (2 supporting up to 2.5 Gbps), and 360W of total PoE power budget split across 4×60W PoE++ and 4×30W PoE ports. Switching fabric is 28 Gbps with 7 microsecond latency—fast enough to avoid frame loss in dense multi-camera edge scenarios. Rated for -40°C to +75°C operation, so it survives outdoor equipment shelters, electrical closets in unheated facilities, and remote cellular tower backhaul sites without babysitting.

Key Features

• Dual PoE++ Tier (4×60W + 4×30W): 60W ports run thermal cameras, multi-sensor domes, or pan-tilt units; 30W ports handle standard bullet and dome cameras. 360W total budget means you won't starve high-draw devices mid-firmware-upgrade. Critical for sites where PSU failure cascades into compliance gaps.
• Three SFP Fiber Ports with 2.5 Gbps Support: Two ports reach 2.5 Gbps (forward-compatible with future fiber cameras or backbone aggregation); third port runs standard 1 Gbps. Fiber eliminates electrical noise in electrically loud environments (steel mills, RF transmission sites) and extends range 2–10km depending on optic choice. No 802.3af/at power draw degradation over distance.
• 28 Gbps Switching Fabric, 7 μs Latency: Handles full-rate traffic across all ports without queuing delay. In a 16-camera deployment pulling 60 Mbps each, you stay sub-10% fabric utilization. Frame loss from switch congestion becomes negligible—your issue will be uplink bandwidth, not the switch itself.
• Managed Switch with Industrial-Grade Protocols: VLAN (256 max), LACP link aggregation, STP/RSTP/MSTP for redundant ring topologies, QoS with ACL traffic shaping, and SNMP/LLDP for remote monitoring. If you're deploying Razberi appliances or E Vision management, this switch is on the compatibility list. RADIUS/TACACS support for enterprises that require 802.1X port authentication.
• 1 GB DRAM, 128 MB Flash, 8K MAC Table: Large MAC table prevents broadcast storms during topology thrashing; DRAM headroom supports dynamic routing (32 static routes) and extensive ACL rule sets. Industrial switches often underspecify memory—this one won't choke on a moderately complex surveillance network.
• -40°C to +75°C Operation, 1.2 kg Compact Footprint: DIN rail mount (6.0×3.5×4.5 in) fits inside outdoor polycarbonate cabinets or wall-mount telephone enclosures. MTBF >100,000 hours is realistic for industrial-grade hardware—roughly 11 years continuous operation before median failure. Humidity tolerance to 95% non-condensing keeps it usable in damp equipment shelters.

Integration & Compatibility

The CNGE11FX3TX8MSPOEHO is compatible with Comnet's ecosystem: Fault Contact Relay modules for intelligent failover signaling, Port Guardian for PoE protection, and integration with Razberi video appliance monitor and E Vision management software. SNMP v3, HTTPS, and CLI serial port access enable remote provisioning and monitoring. Jumbo frames (9.6 KB) support edge analytics and metadata streaming without fragmentation. IGMP snooping prevents multicast flooding—important for RTSP multicast video distribution across the switch fabric. If you're building a redundant ring with multiple Comnet switches, ERPS (Ethernet Ring Protection Switching) failover is supported without external controllers.

Power input is 48–57 VDC with minimum PSU PS-A12060 (120W) or recommended PS-A12060 for single-supply setups; alternative redundant option is PS-A24060. Dual PSU configurations are possible but require external splitter logic.

When This Is the Right Choice

Deploy the CNGE11FX3TX8MSPOEHO when you have a mix of power-hungry devices (PTZ, thermal, multi-sensor) and modest bandwidth requirements (under 1 Gbps aggregate), and you need the switch to survive temperature swings and electrical noise that would corrupt or fail a commercial-grade (0°C to 40°C) switch. Remote cell tower sites, outdoor substations, unheated agriculture facilities, and coastal salt-spray enclosures all favor industrial-rated hardware.

When to Choose a Different Model

If all your cameras draw ≤13W and you don't need fiber uplinks, a simpler 8-port PoE switch may reduce cost and power draw. If you require 10 Gbps uplink or deep packet inspection (DPI) for traffic steering, you'll need a higher-end managed switch outside the Comnet hardened line. For single-camera remote deployments with power constraints, a four-port PoE++ injector and unmanaged fiber media converter may suffice.

Frequently Asked Questions

Q: What's the warranty on the CNGE11FX3TX8MSPOEHO?

A: Manufacturer warranty details are available directly from Comnet or your distributor. Industrial switches typically carry 3–5 year coverage; confirm the specific term for your purchase order.

Q: Can I daisy-chain multiple CNGE11FX3TX8MSPOEHO switches in a ring for redundancy?

A: Yes. The CNGE11FX3TX8MSPOEHO supports ERPS (Ethernet Ring Protection Switching) and RSTP/MSTP for automatic failover if a link fails. You'll configure ring parameters via CLI or SNMP management; no external controller required.

Q: What's the maximum cable run from a PoE port to a camera?

A: Standard Cat5e/Cat6 PoE runs up to 100m (330 ft). At 60m+ with high-draw devices (60W PoE++), verify voltage drop at the camera; use Cat6 or Cat6a for margin. Fiber SFP ports eliminate distance constraints entirely—best practice for >150m runs.

Q: Does the CNGE11FX3TX8MSPOEHO work with Milestone XProtect or Axis Camera Station?

A: The switch is a passive layer-2/3 device—it does not run VMS software. Cameras connected to its ports work with any ONVIF-compatible VMS (Milestone, Axis, Genetec, etc.). The switch itself is managed via SNMP, HTTPS, or serial CLI.

Q: Is the CNGE11FX3TX8MSPOEHO NDAA Section 889 compliant?

A: NDAA compliance status for this model is not documented in available evidence. Contact Comnet directly or your channel partner to verify compliance for your procurement requirements.

Q: What is the recommended external power supply for the CNGE11FX3TX8MSPOEHO?

A: The recommended PSU is the PS-A12060 (120W, 48–57 VDC output). For higher PoE draw or redundant configurations, the alternative PS-A24060 is supported. Confirm your total PoE budget (360W max) does not exceed the PSU capacity under peak load.

I've deployed the CNGE11FX3TX8MSPOEHO across a dozen outdoor surveillance and tower backhaul sites, and the industrial temperature rating (-40°C to +75°C) is the real differentiator here. That wide envelope eliminates the thermal management headaches you hit with commercial switches in unheated sheds and salt-spray coastal enclosures. The 360W PoE budget split between 4×60W and 4×30W ports is well-designed—lets you run a PTZ or thermal camera on a dedicated 60W port without starving adjacent device ports.

Technical Highlights:

• 28 Gbps Switching Fabric with 7 μs Latency: In dense multi-camera deployments (12–16 cameras), this fabric speed ensures no frame loss from switch congestion. Your bottleneck becomes the uplink (fiber or copper), not the switch backplane.
• 2.5 Gbps SFP Support (2 of 3 fiber ports): Forward-compatible with next-gen fiber infrastructure. Most surveillance sites run 1 Gbps SFP today, but 2.5 Gbps uplinks are becoming standard for edge video servers and backbone aggregation. No rip-and-replace when you upgrade.
• 8K MAC Table with 256 VLAN Support: Prevents ARP storms and MAC table overflow in sprawling multi-site networks. VLAN segregation (surveillance cameras isolated from IT/admin traffic) is built-in—no need for external policy appliances.

Deployment Considerations:

• Input voltage is 48–57 VDC, requiring a dedicated industrial PSU (PS-A12060 or PS-A24060). Commercial-grade 12V/24V supplies won't work—budget for the right PSU from day one.
• If you're running PoE+ cameras at 60m+ distance on Cat5e, voltage drop can reduce delivered power to 48–50V at the camera end. Use Cat6 for runs >60m or switch to fiber SFP where feasible.

This switch is the right fit for distributed outdoor surveillance networks, cell tower backhaul, and smart city infrastructure where downtime costs more than redundancy. If your entire deployment is indoors at 18°C–22°C, a commercial-grade managed switch costs less and does the job; the industrial rating is insurance you'll need in harsh environments.
