Features and Advantages
- 24 copper RJ45 ports connect controllers, workstations, FBM devices and network endpoints in the Foxboro Evo control network.
- Two fixed Gigabit RJ45 ports plus two SFP uplink ports support flexible copper or fiber uplink topology.
- Managed VLAN, RSTP and QoS features support network segmentation, redundancy and traffic priority.
- Console, SNMP/RMON and web/CLI management simplify configuration, monitoring and fault diagnosis.
- Port mirroring allows network traffic to be redirected to an external analyzer without disrupting production traffic.
- Optional redundant power supply removes a single power-point failure in critical control networks.
- 1U rack, shelf or desktop installation suits control cabinets, equipment rooms and network racks.
- Designed for small-to-medium industrial Ethernet switching and direct end-station connectivity.
Applications
- Foxboro Evo and I/A Series DCS control network infrastructure
- Connection of controllers, FBM field modules, engineering stations and printers
- Industrial plant Ethernet backbone and local cabinet switch deployment
- Redundant or segmented control-network VLAN architectures
- Network monitoring, diagnostics and uplink aggregation in process automation
Installation and Usage Notes
- Confirm the switch firmware, license and feature set match the Foxboro Evo network design before deployment.
- Use shielded or unshielded twisted-pair cable per the port speed and installation environment; keep copper runs within Ethernet distance limits.
- Populate SFP/Mini-GBIC uplink modules only with compatible approved transceiver types.
- For redundant power, connect two independent branch circuits according to the manual; do not rely on a single shared feed.
- Plan VLAN, STP/RSTP root bridge, port priority and uplink paths to avoid loops or broadcast congestion.
- Keep management console and SNMP access secured according to plant network policy.
- Maintain adequate ventilation, rack clearance and EMC/grounding in the control cabinet.
- Verify actual supply voltage, temperature range and weight from the unit nameplate or official Foxboro PSS document before procurement.
