Comxus CX-NPA-4GS2I-L2 is a next-generation, rugged, industrial-grade PoE switch. It is designed to deliver both power and data connectivity through a single Ethernet cable. This compact, managed switch features 4 PoE-enabled Ethernet ports and 2 SFP uplinks. The PoE ports allow you to connect networking devices such as CCTV cameras and industrial controllers, while the SFP ports enable seamless network expansion. Its compact design makes it an ideal solution for environments where space is limited. Built for harsh industrial conditions, Comxus switches are known for their rugged and reliable performance. They are engineered to withstand extreme temperatures, vibrations, dust, and electrical interference. Our 4-port industrial-grade switches operate efficiently in temperatures ranging from -40°C to +85°C, making them an ideal choice for oil & gas, manufacturing, transportation, and industrial automation sectors.

Why Choose a Managed Industrial PoE Switch?​

A managed PoE switch offers significant benefits over an unmanaged one—especially in mission-critical industrial applications. With Layer 2+ management features, you can:
  • Prioritize traffic using Quality of Service (QoS)
  • Improve security with VLAN segmentation
  • Monitor port status and power consumption in real time
  • Schedule PoE power delivery based on operational hours
  • Detect network loops and optimize traffic with Spanning Tree Protocol (STP)
These advanced features empower industrial IT teams to fine-tune network performance, enhance security, and reduce downtime.
