EDS-408A Series

Home  >   MOXA  >   Industrial Network Infrastructure  >  
Ethernet Switches  >   Layer 2 Managed Switches

8-port entry-level managed Ethernet switches

Product Feature

  • Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 switches), and RSTP/STP for network redundancy
  • IGMP Snooping, QoS, IEEE 802.1Q VLAN, and port-based VLAN supported
  • Easy network management by web browser, CLI, Telnet/serial console, Windows utility, and ABC-01
  • PROFINET or EtherNet/IP enabled by default (PN or EIP models)
  • Supports MXstudio for easy, visualized industrial network management


The EDS-408A Series is designed especially for industrial applications. The switches support a variety of useful management functions, such as Turbo Ring, Turbo Chain, ring coupling, IGMP snooping, IEEE 802.1Q VLAN, port-based VLAN, QoS, RMON, bandwidth management, port mirroring, and warning by email or relay. The ready-to-use Turbo Ring can be set up easily using the web-based management interface, or with the DIP switches located on the top panel of the EDS-408A switches.


Additional Features and Benefits

  • DHCP Option 82 for IP address assignment with different policies
  • Supports EtherNet/IP, Modbus TCP and PROFINET
  • EtherNet/IP EDS (Electronic Data Sheet) file, custom AOI (Add-On Instructions) and FactoryTalk® View faceplate available
  • PROFINET GSDML file and SIMATIC STEP 7 device icons available
  • Port mirroring for online debugging
  • Port-based VLAN, IEEE 802.1Q VLAN, and GVRP to ease network planning
  • QoS (IEEE 802.1p and TOS/DiffServ) to increase determinism
  • RMON for proactive and efficient network monitoring
  • SNMPv1/v2c/v3 for different levels of network management security
  • Bandwidth management to prevent unpredictable network status
