Product Overview
The P0973JX (Model STK-RPS-150PS) is a high-reliability redundant power supply (RPS) module designed for the Foxboro I/A Series and Foxboro Evo Ethernet networking equipment. It functions as an external backup power source for managed switches, including the P0973JM, P0973JN, and P0973JP series.
By providing a secondary power path, the P0973JX ensures that critical DCS network communications remain uninterrupted even if a switch’s internal power supply fails. This module is essential for achieving the “Five Nines” (99.999%) availability required in industrial control environments.

Key Features and System Reliability
-
Hot-Swappable Support: Can be added or replaced without powering down the connected switch, allowing seamless maintenance during live operations.
-
Automatic Failover: Instantly takes over if a switch’s internal PSU fails, preventing dropped packets or system reboots.
-
Redundant Configuration: Multiple P0973JX units can be installed in RPS shelves (e.g., STK-RPS-150CH2) to support several switches simultaneously.
-
Industrial Hardening: Advanced surge protection and EMI filtering withstand the electrical noise typical in motor control centers and turbine halls.
Technical FAQ
Q1: Is the P0973JX compatible with Power over Ethernet (PoE) switches?
A: No. It is a Non-PoE power supply, providing logic power for switch operation only. PoE devices (e.g., IP cameras, wireless access points) require a higher-wattage RPS.
Q2: How do I confirm the module is working correctly?
A: The front-panel LED indicates status:
-
Solid green: AC input active and DC output ready
-
Amber or off: Fuse failure or internal component fault
