Industrial Ethernet Solutions

The EDS-405A/408A are entry-level 5 and 8-port managed Ethernet 
switches 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-

•  Command Line Interface (CLI) for quickly configuring major 

managed functions

•  IPv6 Ready logo awarded (IPv6 Logo Committee certified)

•  DHCP Option 82 for IP address assignment with different policies

•  Support EtherNet/IP and Modbus/TCP protocols for device 

management and monitoring

•  Compatible with EtherNet/IP and PROFINET protocols for 

transparent data transmission

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-405A/408A switches.

•  Turbo Ring and Turbo Chain (recovery time < 20 ms @ 250 

switches), and RSTP/STP for network redundancy 

•  IGMP snooping and GMRP for filtering multicast traffic

•  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 efficient network monitoring and proactive capability

•  SNMPv1/v2c/v3 for different levels of network management  

security

•  Bandwidth management to prevent unpredictable network status

•  Port mirroring for online debugging
