FOXBORO P0973JP is a managed industrial Ethernet switch featuring 8 × 100Base-FX fiber ports and 8 × 10/100Base-T copper ports.
It is fully compatible with Foxboro I/A Series and Evo DCS systems, and is designed for hybrid fiber–copper access and redundant stacking in process industry networks.

The switch is typically used for long-distance fiber communication between control rooms and field cabinets, while simultaneously supporting local copper-based device access, making it ideal for mixed-link industrial environments.

Function and Positioning

Hybrid fiber–copper access
Provides 8 fiber-optic ports for long-distance, EMI-immune transmission and 8 copper Ethernet ports for local equipment access. Optimized for hybrid network architectures between control rooms and on-site cabinets.

Redundancy and high availability
Supports power redundancy, stack redundancy, and dual-link redundancy. Critical nodes can be configured in dual-unit hot-standby mode to ensure continuous and reliable network operation.

Traffic management and network security
Supports QoS priority scheduling to guarantee deterministic transmission of control and alarm traffic. Includes ACLs, port security, and IEEE 802.1X authentication to prevent unauthorized access and meet DCS network isolation requirements.

Remote management and maintenance
Supports combined out-of-band and in-band management, enabling remote diagnostics, configuration backup, and firmware upgrades, effectively reducing operation and maintenance costs.

Typical Application Scenarios

Control room to on-site cabinet hybrid networking
Used in small- and medium-sized systems where control rooms are connected to field cabinets via fiber-optic links, while local instruments, controllers, and maintenance terminals are connected through copper Ethernet.
