The EDS-4008-2MST-HV-T is a rugged managed Layer 2 Fast Ethernet switch engineered for industrial networks that need a compact form factor with serious reliability. It provides six 10/100BaseTX RJ45 ports and two 100BaseFX multi‑mode ST fibre ports to mix local copper connections with long-distance Fibre or high-speed uplinks as required by the specific variant.
Certified to IEC 62443-4-1 and IEC 62443-4-2, it enables secure operation with VLAN segmentation, user authentication, access control, and event logging. Network resilience is delivered through Turbo Ring and Turbo Chain (sub-20 ms recovery under typical loads) alongside RSTP/STP for standards-based redundancy.
Powering is tailored for the environment: this model supports 88V to 300V DC or 85V to 264V AC Power Input, matching common control-panel and field-cabinet supplies without extra conversion hardware. The design uses an IP40 metal enclosure, fanless cooling, DIN-rail mounting, and status LEDs plus a fault relay output to simplify diagnostics and maintenance.
Operating temperature is rated for –40 °C to 75 °C, supporting dependable service in harsh outdoor locations, unconditioned roadside cabinets, and exposed industrial sites.
Management and monitoring are streamlined with MXstudio, LLDP, SNMPv1/v2c/v3, and a rich web/CLI interface, while features such as quality of service, IGMP Snooping/Querier, port trunking with LACP, and port mirroring help optimise deterministic traffic for control, video, and telemetry.
Typical applications include power substations, rail signalling, and distributed transport infrastructure where high-voltage feeds and fibre backbones are standard.
Whether deployed in brownfield upgrades or new builds, the EDS-4008-2MST-HV-T helps operators harden their OT networks with consistent security controls and fast recovery from faults, while keeping installation simple and predictable.
Perfect for sites with legacy ST connectors—no re-termination.
Multi-mode links for machine halls and retrofit projects.
Robust ST couplings cope with vibration at wayside locations.
Use T models: Wide-temperature operation for exposed enclosures.
Reliable ST links into older utility infrastructure.
Fast failover preserves SCADA/alarm signalling.
Extend existing ST plants while transitioning to newer media.
Simple, fanless hardware for low-maintenance installs.
