The EDS-518A is a standalone 18-port managed Ethernet switch that provides 2 combo Gigabit ports with built-in RJ45 or SFP slots for Gigabit fiber optic communication. The Ethernet redundant Turbo Ring (recovery time < 20 ms) increases the reliability and speed of your network backbone. The EDS-518A also supports intelligent network management functions, including QoS, IGMP snooping/GMRP, VLAN, Port Trunking, SNMPv1/v2c/v3, IEEE 802.1X, HTTPS, and SSH.

• IPv6 Ready logo awarded (IPv6 Logo Committee certified)
• IEEE 1588 PTP (Precision Time Protocol) for precise time synchronization of networks (available soon)
• DHCP Option 82 for IP address assignment with different policies (available soon)
• Modbus/TCP industrial Ethernet protocol supported (available soon)
• IEC 61850 GOOSE messaging compliance 
• Turbo Ring (recovery time < 20 ms at full load) and RSTP/STP (IEEE 802.1w/D) 
• 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/1Q) and TOS/DiffServ to increase determinism
• Port Trunking for optimum bandwidth utilization
• IEEE 802.1X, HTTPS, and SSH to enhance network security (available soon: SSH)
• SNMPv1/v2c/v3 for different levels of network management
• RMON for efficient network monitoring and proactive capability
