Comnet CNGE24MS vs TP-Link SG3428XPP-M2: Specification Comparison
Both the Comnet CNGE24MS and TP-Link SG3428XPP-M2 are 24-port managed switches aimed at professional network infrastructure deployments, but they target meaningfully different segments: the CNGE24MS is an industrial-grade, fiber-capable unit with no PoE, rated for extreme temperatures, while the SG3428XPP-M2 is a commercial multi-gigabit PoE++ switch designed for high-density powered-device deployments. Buyers comparing these are typically weighing ruggedized, fiber-integrated edge switching against high-throughput PoE capacity for cameras, APs, and intercoms.

Which switch delivers more bandwidth and port speed for your devices?
The CNGE24MS provides 16 × 10/100/1000Base-T copper ports and 8 × 100/1000Base-Fx SFP fiber ports, for a switching bandwidth of 48 Gbps with a forwarding latency of 7 μs. All copper ports are capped at 1 Gbps maximum.
The SG3428XPP-M2 offers 24 × 2.5 Gbps copper PoE++ ports plus 4 × 10 Gbps SFP+ uplink slots, yielding a total switching capacity of 200 Gbps and a forwarding rate of 148.80 Mpps. Every copper port runs at up to 2.5× the speed of the CNGE24MS copper ports.
For raw throughput and per-port speed, the SG3428XPP-M2 holds a decisive numerical advantage: 200 Gbps versus 48 Gbps switching capacity, and 2.5 Gbps versus 1 Gbps per copper port. Buyers running high-bitrate multi-sensor cameras or dense Wi-Fi 6 APs will feel this difference; buyers with legacy 1G endpoints will not.
Which switch handles PoE budgets and environmental conditions better?
The CNGE24MS carries no PoE capability whatsoever. Its power draw is a modest 25 W from a 100–240 VAC input. Its industrial design is rated for an operating temperature range of −40 °C to +70 °C and storage to +85 °C, making it suitable for outdoor enclosures, transit hubs, and factory floors without supplemental heating or cooling.
The SG3428XPP-M2 delivers up to 770 W of total PoE budget across its 24 ports, with each port supporting up to 90 W via 802.3bt (PoE++). It also supports 802.3af and 802.3at standards. Maximum power consumption is rated at 500 W. Its operating temperature range is −5 °C to +45 °C, which is a commercial/indoor envelope.
These two switches occupy opposite ends of the power-and-environment spectrum. The CNGE24MS is the correct choice for installations with no powered endpoints but demanding thermal or EMI conditions. The SG3428XPP-M2 is the correct choice for densely powered indoor deployments; it cannot be deployed where ambient temperatures fall below −5 °C or exceed +45 °C.
Which switch offers stronger redundancy, management, and security features?
The CNGE24MS specifies an extensive set of ring and redundancy protocols: C-Ring, Legacy Ring, C-Chain, MRP, Fast Recovery, MSTP, RSTP, and STP. These are industrial-grade, sub-50 ms recovery protocols commonly required in OT and physical-security networks. Security features listed include Device Binding, Port-Based Network Access Control, RADIUS, SNMPv3, and HTTPS/SSH. MAC table size is 8,000 entries; max VLANs is 256; jumbo frame support is 9.6 K.
The SG3428XPP-M2 is managed via TP-Link's Omada platform (cloud or standalone controller). Specified operating modes include Store-and-Forward, Static Routing, VLAN, ACL, QoS, IGMP Snooping, OAM, and DDM. It carries 256 MB DRAM and 32 MB Flash. ONVIF support is noted. Specific redundancy protocol support (STP/RSTP/MSTP or ring variants), MAC table size, VLAN count maximum, and granular security protocol list are not provided in the supplied specifications.
The CNGE24MS has a materially more detailed and proven redundancy story, particularly for ring topologies common in surveillance and industrial automation. The SG3428XPP-M2's Omada ecosystem offers centralized cloud management and ONVIF integration that the CNGE24MS spec sheet does not reference, which favors unified IP camera and access-point management workflows.
Which should you choose: the CNGE24MS or the SG3428XPP-M2?
Our take: The CNGE24MS is the stronger choice when the installation demands extreme-temperature operation, fiber uplinks, and deterministic ring redundancy. It operates from −40 °C to +70 °C versus the SG3428XPP-M2's −5 °C to +45 °C commercial envelope, includes eight 100/1000Base-Fx SFP fiber ports where the TP-Link has none, and specifies eight named redundancy protocols including C-Ring and MRP for sub-50 ms fault recovery. Conversely, the SG3428XPP-M2 dominates on power delivery and speed: 770 W PoE++ budget (versus zero PoE on the CNGE24MS), 2.5 Gbps per copper port versus 1 Gbps, and 200 Gbps total switching capacity versus 48 Gbps. Choose the CNGE24MS for harsh-environment, fiber-integrated, or OT/ICS network edges where PoE is handled externally. Choose the SG3428XPP-M2 for indoor, PoE-heavy deployments—high-density IP camera clusters, Wi-Fi 6 APs, or intercoms—running under the Omada management platform.

Frequently Asked Questions
Which should you choose: the CNGE24MS or the SG3428XPP-M2?
The CNGE24MS is the stronger choice when the installation demands extreme-temperature operation, fiber uplinks, and deterministic ring redundancy. It operates from −40 °C to +70 °C versus the SG3428XPP-M2's −5 °C to +45 °C commercial envelope, includes eight 100/1000Base-Fx SFP fiber ports where the TP-Link has none, and specifies eight named redundancy protocols including C-Ring and MRP for sub-50 ms fault recovery. Conversely, the SG3428XPP-M2 dominates on power delivery and speed: 770 W PoE++ budget (versus zero PoE on the CNGE24MS), 2.5 Gbps per copper port versus 1 Gbps, and 200 Gbps total switching capacity versus 48 Gbps. Choose the CNGE24MS for harsh-environment, fiber-integrated, or OT/ICS network edges where PoE is handled externally. Choose the SG3428XPP-M2 for indoor, PoE-heavy deployments—high-density IP camera clusters, Wi-Fi 6 APs, or intercoms—running under the Omada management platform.
Can the CNGE24MS or SG3428XPP-M2 power IP cameras directly?
Only the SG3428XPP-M2 supports PoE. It delivers up to 90 W per port via 802.3bt (PoE++) with a total budget of 770 W, covering 802.3af and 802.3at cameras as well. The CNGE24MS has no PoE capability whatsoever; cameras would require separate PoE injectors or a separate PoE switch if connected to the CNGE24MS.
Which switch is better suited for an outdoor or industrial enclosure?
The CNGE24MS is the clear choice. Its operating temperature range of −40 °C to +70 °C and storage range to +85 °C meet industrial and outdoor-enclosure requirements. The SG3428XPP-M2 is rated only to −5 °C minimum and +45 °C maximum, which is a standard commercial indoor envelope and unsuitable for unheated outdoor cabinets in cold climates.
Is the CNGE24MS or SG3428XPP-M2 better for a site that already uses fiber backbone cabling?
The CNGE24MS is the better fit. It includes 8 × 100/1000Base-Fx SFP fiber ports natively, alongside its 16 copper ports, supporting direct fiber integration without additional media converters. The SG3428XPP-M2's 4 × 10 Gbps SFP+ slots accept fiber SFP+ modules for uplinks, but the spec notes single-mode or multimode capability depends on the module chosen; no dedicated fiber access ports are specified for end-device connections.
