The Moxa EDS-518A is a rugged industrial-grade managed Ethernet switch featuring 18 ports – 16 Fast Ethernet (10/100BaseT(X)) and 2 Gigabit combo ports that support either RJ45 copper or 100/1000BaseSFP modules. Designed for critical infrastructure, the EDS-518A uses Turbo Ring and Turbo Chain redundancy (recovery time < 20 ms with up to 250 switches), ensuring maximum network availability in demanding environments.

The switch offers comprehensive Layer 2 management, including VLAN, QoS, and port trunking, plus advanced security functions such as IEEE 802.1X, TACACS+, SSH, and HTTPS. Configuration is accessible via CLI, web browser, or the ABC-01 USB backup tool. It also supports industry-standard protocols such as Modbus TCP, EtherNet/IP, and PROFINET.
