The EDS-4009-3MSC-HV is designed for control rooms and substations that prefer high-voltage feeds. It combines six 10/100 copper ports with three 100Base-FX multi-mode SC ports (typical 5 km reach at 1310 nm) and features Turbo Ring/Chain for < 20 ms failover at scale. RSTP/MSTP and LACP provide standards-based redundancy and aggregation.
Security aligns with IEC 62443-4-2 SL2 and includes HTTPS/SSH, 802.1X, ACLs, DHCP snooping, storm control and MAC protections. Visibility is provided through MXstudio, SNMPv1/v2c/v3, LLDP, RMON, syslog and SPAN/RSPAN, with fibre check for optical troubleshooting. EtherNet/IP, Modbus TCP and PROFINET devices are supported, while IEEE 1588v2 PTP (hardware-based) meets utility timing profiles.
The switch offers 16,000 MAC entries, a 1 MB buffer, jumbo frames of up to 9,216 bytes, four quality of service queues, 256 VLANs, and IGMP snooping/querier. Power is single-input high voltage: 110/220 VDC or 85–264 VAC (operating 88–300 VDC, 85–264 VAC). The IP40 metal chassis supports DIN-rail or wall mounting and operates from -10 to 60°C. Certifications include EN 50121-4 and IEC 61850-3 / IEEE 1613 for substation environments.
