The Foxboro P0973JP A4H254-8F8T is a high-performance industrial Ethernet switch designed for mission-critical networking in harsh environments. Engineered by Extreme Networks (branded under Foxboro), it combines fiber optic and copper connectivity to deliver reliable, high-speed data transmission for industrial automation systems. Below is its detailed specification in English:
The P0973JP A4H254-8F8T is part of the Foxboro A4 Series, a line of ruggedized switches optimized for industrial control networks. It serves as a backbone for connecting field devices, controllers, and 上位机 (supervisory systems) in applications requiring low latency, high scalability, and resistance to electromagnetic interference (EMI). Its modular design supports flexible configurations, making it suitable for process industries, power generation, and smart manufacturing.
Dual-Media ConnectivityCombines copper (RJ45) and fiber (SFP) ports to support long-distance 传输 (up to 20 km via single-mode fiber) and short-range connections, ideal for hybrid network topologies.
High Availability
- Redundant Power: Supports external redundant power supply modules (RPSM) for uninterrupted operation.
- Stacking: Up to 8 switches can be stacked via RJ45 or SFP ports, forming a single virtual switch with shared configuration and redundancy.
- Link Aggregation: Bond multiple ports for increased bandwidth and failover protection.
Advanced Networking
- Layer 3 Routing: Static routing and VLAN-based segmentation for network isolation.
- Quality of Service (QoS): Prioritizes critical traffic (e.g., control signals) over non-essential data.
- SNMP Management: Remotely monitor and configure via SNMPv3, WebView, or CLI.
Industrial Hardening
- Rugged Design: Enclosed metal casing with DIN-rail mounting for harsh environments.
- EMI Resistance: Shielded against electromagnetic interference common in industrial settings.
- Wide Voltage Input: AC 100–240 V ensures compatibility with global power grids.
Security
- Port Security: Restricts unauthorized devices via MAC address filtering.
- Access Control Lists (ACLs): Filters traffic based on IP/MAC addresses or protocols.
- 802.1X Authentication: Enhances network security through user/device authentication.
- Process Automation: Connects PLCs, DCS controllers, and field instruments in chemical, petrochemical, and pharmaceutical plants.
- Power Generation: Integrates with turbine/generator monitoring systems and SCADA networks in power plants.
- Manufacturing: Supports real-time data exchange between robotics, CNC machines, and quality control systems.
- Smart Cities: Used in traffic management, water treatment, and utility grids requiring reliable edge networking.
- Stack of 4 P0973JP switches (total 64 ports: 32x RJ45, 32x SFP).
- Redundant power via 2x RPSM modules.
- Fiber uplinks to a central core switch for long-distance connectivity.
- VLANs segmented by process area (e.g., VLAN 10 for control, VLAN 20 for diagnostics).
- User Manual: Available on Foxboro’s official website or via authorized distributors.
- Firmware Updates: Regular updates to enhance security and add new features.
- Technical Support: Emerson (Foxboro’s parent company) provides 24/7 assistance for critical issues.
The Foxboro P0973JP A4H254-8F8T balances industrial durability with enterprise-grade networking capabilities, making it a preferred choice for organizations demanding reliable, scalable, and secure communication in mission-critical environments.
