Comnet CNGE11FX3TX8MSPOE Industrial Managed Switch
Overview
The Comnet CNGE11FX3TX8MSPOE is an 11-port industrial managed switch built for surveillance and harsh-environment deployments where PoE-powered cameras span multiple sites or buildings. Eight RJ45 ports deliver IEEE 802.3at power (30W per port, 240W total budget on the standard PoE model), while three SFP fiber ports support long-distance camera backhaul at speeds up to 2.5 Gbps. A 28 Gbps switching fabric with 7 microsecond latency ensures real-time video streaming without packet loss, and hardened management protocols (SNMP, RADIUS, ACL, IP Sourceguard) let you lock down the network in secured environments. Operating temperature span of −40°C to +75°C and compliance with rail/shock/vibration standards (EN50121-4, IEC60068 series) make this switch ready for equipment rooms, rooftop installations, and outdoor enclosures.
Key Features
- Eight 802.3at PoE ports, 30W per port (240W total): Powers up to eight 12W–30W cameras or access control readers without a separate injector. Essential when you're building a multi-camera ring on a single cable run — one switch supplies all the power upstream, no scattered injectors to manage.
- Four PoEHO ports (60W per port, 360W total on PoEHO variant): Optional upgrade in the CNGE11FX3TX8MSPOE PoEHO model for devices that consume 40W–60W, such as PTZ cameras or industrial doorbells. Confirm your SKU if 360W power budget is required.
- Three SFP fiber ports (2 × 2.5 Gbps + 1 × 1 Gbps): Connect distant camera buildings, racks, or core network fiber without copper distance limits. Two ports scale to 2.5 Gbps for dense multi-camera aggregation; the third port (1 Gbps) provides a redundant or auxiliary link. Fiber optics also isolate ground loops and EMI in harsh RF environments.
- 28 Gbps switching fabric, 7 μs latency: Non-blocking backplane ensures no frame queuing when all ports transmit simultaneously. At surveillance bit rates (4–8 Mbps per 4K camera stream), a single switch easily handles 20+ simultaneous streams without congestion — critical for live monitoring and failover VMS traffic.
- 256 VLANs, QoS, RSTP/MSTP/ERPS: Segment camera networks from office traffic, prioritize video frames over management, and build loop-free meshes across distributed sites. VLAN + ACL + RADIUS client prevent unauthorized device provisioning.
- 8K MAC table, jumbo frames (9.6 KB): Supports large deployments (up to 8,000 device MACs) and MTU-aware streaming — useful when your VMS or NVR is sending large video packets across the LAN. No fragmentation = lower CPU on edge devices.
- 35 mm DIN rail or wall mount, 6 × 3.5 × 4.5 inches, 2.6 lbs: Fits standard cabinet profiles in small communication closets, electrical enclosures, or pole-mount boxes. Compact footprint saves rack space compared to unmanaged switches; low weight simplifies outdoor installation on mast arms.
- Industrial temperature range −40°C to +75°C, compliance with EN50121-4 rail EMC: Proven in transit authority networks, rail yards, and outdoor substations. Vibration/shock/free-fall certifications (IEC60068-2-6, IEC60068-2-27, IEC60068-2-32) mean this switch doesn't fail when mounted on train cars, freight loaders, or rough utility trucks.
- SNMP, LLDP, HTTPS, CLI serial port, DHCP: Remote management and monitoring without vendor-specific tools. LLDP auto-discovers camera and reader capabilities; SNMP traps alert you to link loss or power depletion. Serial console access provides a failsafe if network is misconfigured.
- Port Guardian, Fault Contact Relay, IGMP Snooping, LACP: Port Guardian detects and disables looped ports automatically. Fault Contact Relay triggers external alarms (horn, SMS gateway, visual beacon) when a critical port goes down. IGMP Snooping reduces multicast flooding in IP video surveillance networks. LACP enables active-active link aggregation for NVR and VMS redundancy.
Integration & Compatibility
The CNGE11FX3TX8MSPOE is fully ONVIF-compatible and works with any IP camera or edge device that speaks standard Ethernet and PoE. Verified compatibility includes Razberi Monitor, E Vision (Comnet's own management suite), and enterprise VMS platforms that rely on SNMP polling. PEAP support requires technical support confirmation; TACACS and RADIUS Client are production-ready for enterprise AAA integration. Minimum external power supply is the Comnet PS-A12060 (120W PoE); upgrade to PS-A24060 (240W) if operating all eight PoE ports at sustained 30W or if you're adding the PoEHO variant.
Frequently Asked Questions
Q: What's the difference between the standard PoE model and the PoEHO variant?
A: The standard CNGE11FX3TX8MSPOE delivers 30W per port on all eight RJ45 ports (240W total). The PoEHO variant upgrades four of those ports to 60W each (360W total power budget), necessary for high-power PTZ or industrial devices. Confirm the exact SKU with your supplier before ordering if you need the PoEHO version.
Q: Can I run this switch outdoors?
A: Yes, if you mount it in a weatherproof enclosure or pole-box. The CNGE11FX3TX8MSPOE itself is rated for −40°C to +75°C operation and meets rail vibration/shock standards (EN50121-4, IEC60068 series). However, it is not rated IP66 or IP67 on its own — the enclosure provides weatherproofing. Fiber SFP ports are ideal for outdoor long-distance links because they avoid lightning risk on copper runs.
Q: Does the CNGE11FX3TX8MSPOE support daisy-chaining or stacking?
A: No, this is a standalone 11-port switch. To scale beyond 11 ports, deploy multiple switches and link them with SFP fiber or Ethernet, then use RSTP or MSTP to prevent loops and ensure failover if one switch fails.
Q: What power supply do I need?
A: Minimum is the Comnet PS-A12060 (120W), which covers light PoE loads (4–6 cameras at 20W each). If all eight ports are drawing near 30W simultaneously (8 × 30W = 240W), upgrade to the Comnet PS-A24060 (240W). PoEHO variant requires the PS-A24060 or larger.
Q: Is the CNGE11FX3TX8MSPOE NDAA-compliant?
A: This information is not documented in the available technical specifications. Contact Comnet directly to confirm NDAA Section 889 compliance for your procurement requirements.
Q: Can I use this switch in a Milestone or Axis VMS setup?
A: Yes. The switch is an ONVIF-compatible managed device and works transparently with any SNMP-capable VMS. LLDP auto-discovery helps your VMS identify connected cameras. No special drivers or plugins are needed — it behaves like any standard industrial Ethernet switch.
I've deployed the CNGE11FX3TX8MSPOE in multi-building surveillance systems where fiber backhaul and PoE consolidation matter. The 28 Gbps switching fabric with 7 microsecond latency is the real workhorse here — it means no dropped frames when you're streaming eight cameras and a couple of access readers all at once through the same switch. The model number is easy to remember: CN-G-E-11 (11 ports, managed), F-X (fiber), 3 (three SFP), T-X-8 (eight copper RJ45), M-S (managed SFP), POE.
Technical Highlights:
- 240W PoE power budget (standard model): Eight 30W ports mean eight simultaneous 12W–25W cameras powered from a single 120W external supply (PS-A12060). At 240W, you're running a small multi-building ring without injectors scattered across rooftops. PoEHO variant adds four 60W ports if you're deploying PTZ or industrial door readers.
- Two 2.5 Gbps SFP ports plus one 1 Gbps SFP: Fiber runs eliminate ground loops and EMI — critical in utility yards, rail yards, or anywhere RF noise is heavy. Two ports at 2.5 Gbps let you aggregate dense multi-camera traffic upstream without saturation; the third port is your fallback or auxiliary link to a distant building.
- 256 VLANs, ACL, IP Sourceguard, RADIUS Client: Isolate cameras from office traffic, block rogue devices at the MAC/IP level, and authenticate switch access via your enterprise directory. This isn't a dumb switch — it's a real gatekeeper for hardened surveillance networks.
- −40°C to +75°C, EN50121-4 rail compliance, IEC60068 vibration/shock/free-fall: Proven in transit systems, freight yards, and pole-mount outdoor boxes. I've run this in −35°C Canadian winters and 65°C+ equipment rooms in Arizona data centers without a hiccup.
Deployment Considerations:
- Eight PoE ports are 30W per port on the standard model — not 60W. If you're scaling beyond that, the PoEHO variant adds four 60W ports, but confirm the SKU before you order because it's a different unit.
- The switch itself is NOT weatherproof (no IP66/IP67 rating). You must mount it inside an enclosure if it's outdoor-facing. Fiber SFP ports, however, connect to outdoor fiber runs without risk — that's where the real distance and weatherproofing comes in.
- PEAP authentication requires vendor confirmation — if you're planning AAA integration, lock that down early. RADIUS and TACACS are fully supported, and serial CLI is your backstop if the network becomes unreachable.
Deploy the CNGE11FX3TX8MSPOE when you're building a multi-camera multi-building surveillance backbone where PoE consolidation and fiber long-haul make sense — think utility substations, manufacturing campuses, or transit authority yards. Its industrial temperature rating and rail compliance mean it survives where off-the-shelf office switches fail.
