Introducing the CNX28F4T24MP3: Hardened Layer 3 PoE Switch from Comnet
Introduction

When it comes to industrial networking, reliability, scalability, and security are non-negotiable. That’s why Comnet is proud to announce the launch of the CNX28F4T24MP3, a hardened, managed Layer 3 Ethernet switch engineered for the most demanding applications.

Built for Harsh Environments 

The CNX28F4T24MP3 is designed to withstand environmentally challenging conditions while delivering enterprise-level performance. With 24 Gigabit PoE ports supporting IEEE 802.3at and a 720W total PoE budget, it can power a wide range of connected devices such as IP cameras, wireless radios, sensors, and controllers - all from a single rugged platform. 

Four high-speed SFP+ uplink ports provide flexible fiber connectivity at speeds up to 10G, ensuring that your network can handle the bandwidth requirements of today and tomorrow. Comnet SFPs are recommended to optimize performance and distance. 

Layer 3 Intelligence for Smarter Networks 

Unlike basic switches, this unit provides advanced Layer 3 routing protocols including OSPF (v2/v3), RIPv2, static routing, and full IPv6 support. That means smarter, more efficient traffic management for large-scale or segmented networks, reducing bottlenecks and improving resiliency. 

Security You Can Trust 

Cybersecurity threats don’t stop at the perimeter, which is why the CNX28F4T24MP3 integrates advanced safeguards: 

  • 802.1x authentication 
  • Device Binding & ACLs 
  • PoE device alive check and scheduling 
  • HTTPS/SSH encrypted access 

These features protect critical infrastructure from unauthorized access and service interruptions. 

Key Features at a Glance 
  • 24 x 10/100/1000BASE-T(X) PoE ports (up to 30W each, 720W budget) 
  • 4 x 100M/1G/2.5G/10G SFP+ uplink ports 
  • Virtual stacking with single IP management 
  • Rapid redundancy & recovery with IEEE standards 
  • IGMP v2/v3 multicast support for video and data applications 
  • SNMP, LLDP, and SNTP for streamlined management 
  • Redundant DC power inputs for uninterrupted operation 
  • Backed by Comnet’s Limited Lifetime Warranty 
Applications 

The CNX28F4T24MP3 is the ideal backbone for: 

  • Intelligent Transportation Systems (ITS) 
  • Surveillance & Security Networks 
  • Industrial Automation 
  • Power & Utility Infrastructure 
  • Smart Cities and IoT Deployments
