28-Port Managed Industrial Switch | 24-RJ45 Ethernet Ports, 4-SFP Fiber Ports


The VERSITRON SF72860M is an Industrial Gigabit L2 Managed Switch equipped with twenty-four 10/100/1000Mbps RJ45 ports, two 100/1000M SFP fiber uplink ports and two combo ports that provide stable and reliable Ethernet transmission.

For fast and efficient connectivity from the network edge device to a backbone switch or server, the managed Gigabit switch is designed to extend existing LANs through two 100/1000Base-SX/LX SFP interfaces using either one or two multimode or singlemode fibers. The Industrial Managed Switches are fully managed Layer 2 switches not only incorporating the industry standard Rapid Spanning Tree Protocol (IEEE802.1w RSTP), but also a rapid ring recovery protocol enabling operational network recovery in the event of a network or power system failure.

Typical Applications

  • Any network utilizing a mix of copper and fiber
  • Industrial IP connectivity and communication
  • Self-healing Fast Ethernet backbone networks
  • Networks using Ethernet devices such as network cameras, access control, intercoms, etc.
