TP-Link SG3428XPP-M2 vs Comnet CNGE24FX12TX12MSPOE: Specification Comparison
Both the TP-Link SG3428XPP-M2 and the Comnet CNGE24FX12TX12MSPOE are 24-port managed PoE ethernet switches aimed at surveillance and enterprise edge deployments, making them legitimate cross-shop candidates. The comparison spans multi-gigabit copper throughput versus hardened industrial-grade design, high-density PoE++ power delivery versus environmental resilience, and cloud-managed flexibility versus rail-certified ruggedness — three axes that define which switch is the right fit for a given installation environment.

Which switch delivers more bandwidth and PoE power per port?
The TP-Link SG3428XPP-M2 leads decisively on raw throughput and per-port PoE wattage. Its 24 copper ports run at 2.5 Gbps each (versus 1 Gbps on the Comnet's 12 RJ45 ports), and its 4× 10 Gbps SFP+ uplinks push total switching capacity to 200 Gbps at 148.80 Mpps. The Comnet CNGE24FX12TX12MSPOE's switching bandwidth is specified at 54 Gbps with a switching latency of 7 µs — roughly one-quarter of the TP-Link's fabric capacity.
On PoE, the gap is equally wide. The SG3428XPP-M2 supports IEEE 802.3bt (PoE++) at up to 90 W per port with a total budget of 770 W across all 24 ports. The Comnet supports IEEE 802.3at (PoE+) only, capped at 30 W per port, across 12 of its 24 ports, with a maximum power consumption of 390 W. Installers powering PTZ cameras, multi-radio APs, or video intercoms requiring more than 30 W per device must use the TP-Link. The Comnet's 12 SFP fiber ports add a fiber uplink or fiber-edge capability that the TP-Link's SFP+ slots do not replicate in fiber-count terms.
Which switch is built for harsh or outdoor-adjacent environments?
The Comnet CNGE24FX12TX12MSPOE is purpose-engineered for demanding physical environments. Its operating temperature range is -40 °C to +75 °C, compared to the TP-Link's -5 °C to +45 °C — a spread of 85 °C versus 50 °C. It carries formal certifications for shock (IEC 60068-2-27), free fall (IEC 60068-2-32), vibration (IEC 60068-2-6), rail (EN 50121-4), and full EMS immunity testing (EN 61000-4-2 through -11). The TP-Link specifications provided do not list any of these environmental or immunity certifications.
The Comnet also publishes an MTBF figure of greater than 100,000 hours and specifies both mains-powered (11 lb) and DC-only-powered (7.9 lb) weight variants, indicating dual power-input capability suitable for substation or transit cabinet use. The TP-Link SG3428XPP-M2 is a 1U rackmount unit designed for conditioned data-center or IDF-closet environments; its 17.3 × 13.0 × 1.7 in chassis is heavier in implied thermal management but not rated for the temperature extremes or vibration profiles the Comnet tolerates. For rooftop enclosures, transportation, utilities, or outdoor-rated cabinets, the Comnet is the only specced option between the two.
How do these switches differ in management, memory, and network feature depth?
The TP-Link SG3428XPP-M2 is managed via TP-Link's Omada controller — either cloud-hosted or on-premises standalone — providing centralized dashboard management consistent with Omada-based Wi-Fi and router deployments. Its operating modes include Store-and-Forward switching, Static Routing, VLAN, ACL, QoS, IGMP Snooping, OAM, and DDM. Onboard memory is 256 MB DRAM and 32 MB Flash. The switch also declares ONVIF compatibility, which assists with camera discovery in surveillance ecosystems. USB connectivity is specified.
The Comnet CNGE24FX12TX12MSPOE provides substantially more onboard memory: 1 GB DRAM and 128 MB Flash — four times the DRAM and roughly four times the Flash of the TP-Link. It supports up to 256 VLANs, an 8K MAC address table, 9.6K-byte jumbo frames, and 32 static routes. Switching latency is published at 7 µs. The Comnet's management platform details beyond these Layer 2/2+ feature specs are not provided in the supplied specifications. Neither product lists ONVIF support in the Comnet's provided specs. For Omada-ecosystem installers, the TP-Link's controller integration is a concrete advantage; for facilities needing larger DRAM headroom and fiber-edge ports in a hardened chassis, the Comnet's memory and port mix are differentiating.
Which should you choose: the SG3428XPP-M2 or the CNGE24FX12TX12MSPOE?
Our take: The SG3428XPP-M2 is the stronger choice when deploying in a climate-controlled environment where high-density PoE++ power, multi-gigabit copper throughput, and Omada ecosystem integration are the primary drivers. It delivers a 770 W PoE budget versus the Comnet's 390 W total consumption ceiling, a 200 Gbps switching fabric versus 54 Gbps, and 2.5 Gbps per copper port versus 1 Gbps — meaningful deltas for camera-dense or AP-dense deployments. However, the CNGE24FX12TX12MSPOE is the only specced choice for installations requiring operation below -5 °C or above +45 °C, rail-certified (EN 50121-4) or vibration-rated (IEC 60068-2-6) environments, 12 built-in SFP fiber ports, or published MTBF assurance. Buyers integrating into transportation, utilities, or outdoor hardened cabinets should specify the Comnet; buyers building out Omada-managed multi-gig surveillance or wireless LANs in conditioned spaces should specify the TP-Link.

Frequently Asked Questions
Which should you choose: the SG3428XPP-M2 or the CNGE24FX12TX12MSPOE?
The SG3428XPP-M2 is the stronger choice when deploying in a climate-controlled environment where high-density PoE++ power, multi-gigabit copper throughput, and Omada ecosystem integration are the primary drivers. It delivers a 770 W PoE budget versus the Comnet's 390 W total consumption ceiling, a 200 Gbps switching fabric versus 54 Gbps, and 2.5 Gbps per copper port versus 1 Gbps — meaningful deltas for camera-dense or AP-dense deployments. However, the CNGE24FX12TX12MSPOE is the only specced choice for installations requiring operation below -5 °C or above +45 °C, rail-certified (EN 50121-4) or vibration-rated (IEC 60068-2-6) environments, 12 built-in SFP fiber ports, or published MTBF assurance. Buyers integrating into transportation, utilities, or outdoor hardened cabinets should specify the Comnet; buyers building out Omada-managed multi-gig surveillance or wireless LANs in conditioned spaces should specify the TP-Link.
Can either switch power a 60W or 90W PTZ camera or Wi-Fi 6E access point on a single cable?
Only the TP-Link SG3428XPP-M2 supports IEEE 802.3bt (PoE++) with up to 90 W per port. The Comnet CNGE24FX12TX12MSPOE is limited to IEEE 802.3at (PoE+) at a maximum of 30 W per port. Devices requiring more than 30 W — such as high-power PTZ cameras, dual-radio APs, or video intercoms — require the TP-Link.
Which switch is suitable for an outdoor equipment cabinet or a transit/rail installation?
The Comnet CNGE24FX12TX12MSPOE is specified for -40 °C to +75 °C operation and carries EN 50121-4 rail certification, IEC 60068-2-6 vibration, and IEC 60068-2-27 shock ratings. The TP-Link SG3428XPP-M2 is rated only from -5 °C to +45 °C and the provided specifications list no equivalent environmental or rail certifications. For harsh or outdoor-adjacent deployments, the Comnet is the only option between the two based on available spec data.
Is the SG3428XPP-M2 or the CNGE24FX12TX12MSPOE better for a large multi-gig surveillance or wireless LAN deployment?
For high-density multi-gigabit deployments in conditioned spaces, the SG3428XPP-M2 offers a 200 Gbps switching capacity, 24× 2.5 Gbps copper ports, 4× 10 Gbps SFP+ uplinks, and a 770 W PoE budget — all significantly exceeding the Comnet's 54 Gbps fabric, 12× 1 Gbps copper ports, and 390 W total power ceiling. The Comnet's 12 SFP fiber ports are advantageous where fiber edge connectivity is needed, but bandwidth and PoE capacity favor the TP-Link for large-scale deployments.
