Technical Specifications

Solving the Discontinued Hardware Crisis

The Stratix 5700 series was the standard managed switch platform for Rockwell Automation's Integrated Architecture throughout the 2010s. Thousands of manufacturing facilities — automotive assembly, food and beverage, oil and gas, pharmaceutical batch processing — built their plant-floor EtherNet/IP networks around this hardware. Rockwell's end-of-life announcement did not come with a simple drop-in successor. The replacement path involves migrating to the Stratix 5400 or 5410 series, which carry different form factors, different IOS feature sets, and in many cases require topology redesign and re-commissioning of connected PLCs and drives.

DriveKNMS maintains sourced inventory of discontinued Rockwell Automation networking hardware specifically to serve facilities in this position. Each unit is individually assessed before dispatch review.

Condition & Reliability Assurance

Discontinued hardware sourced from the secondary market carries inherent risk if not properly evaluated. DriveKNMS applies a five-step assessment protocol to every unit of the 1783-BMS20CL before it leaves our facility:

• Electrolytic Capacitor Inspection: Aging capacitors are the primary failure mode in legacy switching hardware. Each board is visually and electrically inspected for bulging, leakage, or elevated ESR values.
• Firmware Version Verification: The installed IOS firmware version is confirmed and documented. Units with known vulnerable or unstable firmware builds are flagged and handled accordingly.
• Pin and Connector Corrosion Check: All RJ45 ports, LC fiber connectors, and power terminals are inspected under magnification for oxidation, mechanical damage, or contamination.
• Functional Power-On Test: Each unit is powered at rated voltage and verified to complete its boot sequence, establish management access, and pass basic port-level link testing.
• Cosmetic and Label Verification: Serial number, manufacturing date code, and Rockwell Automation labeling are verified for authenticity and documented in the shipment record.

Key Features for System Maintenance

How do I know the unit is genuine and not counterfeit?
Every unit is inspected for authentic Rockwell Automation labeling, correct date codes, and consistent board-level construction. Shipment documentation includes photos of the unit's serial number plate and assessment checklist.
