Product Description
Allen-Bradley 1783-BMS20CA Replacement/Upgrade Solution for Stratix 5700 — Smooth Transition Guaranteed
The Allen-Bradley 1783-BMS20CA is a 16-port managed industrial Ethernet switch from the Stratix 5700 series, engineered by Rockwell Automation for demanding EtherNet/IP environments. Whether you are retiring an aging unmanaged switch or scaling up from a smaller Stratix platform, the 1783-BMS20CA delivers a seamless migration path with full backward compatibility, advanced VLAN segmentation, and integrated Device Level Ring (DLR) support — all within the familiar Studio 5000 / RSLogix ecosystem.
Industrial facilities running legacy Stratix 2000 or Stratix 6000 infrastructure face increasing pressure: end-of-life firmware, limited port density, and the absence of ring redundancy leave production networks vulnerable. The 1783-BMS20CA resolves all three pain points in a single swap, preserving your existing cable plant and IP addressing scheme while unlocking modern network management capabilities.
At IndCtrlHub, every 1783-BMS20CA ships with a 12-Month Warranty, pre-sales compatibility verification, and post-installation technical support — so your upgrade project stays on schedule and on budget.

Seamless Upgrade Solutions — Migration-Ready Companion Components
A successful Stratix 5700 migration rarely involves a single device swap. When replacing your legacy switch with the 1783-BMS20CA, our engineering team recommends a coordinated upgrade of the surrounding network infrastructure to eliminate compatibility gaps and future-proof your topology.
Step 1 — Fiber Uplink Readiness: If your backbone uses fiber, ensure the correct SFP transceivers are installed. The Allen-Bradley 1783-SFP100FX/A 100BASE-FX Fiber Optic SFP Module and the Allen-Bradley 1783-SFP100LX/A 100BASE-LX Fiber SFP Transceiver Module are direct-fit options for the 1783-BMS20CA combo ports, enabling long-distance fiber runs without additional media converters.
Step 2 — Gigabit Backbone Upgrade: For facilities requiring gigabit uplinks, the Allen-Bradley 1783-SFP1GLX Gigabit SFP Module slots directly into the 1783-BMS20CA, delivering 1000BASE-LX performance on existing single-mode fiber infrastructure.
Step 3 — Tier Expansion: When your network requires additional port density at the edge, pair the 1783-BMS20CA with the Allen-Bradley 1783-BMS06SGL Stratix 5700 6-Port Gigabit Managed Switch or the Allen-Bradley 1783-BMS10CGL Stratix 5700 10-Port Managed Gigabit Switch as downstream access switches — all managed from a single RSLogix/Studio 5000 project.
Step 4 — Layer 3 Core Routing: For multi-subnet plant networks, the Allen-Bradley 1783-RMS10T Stratix 8300 Layer 3 Ethernet Switch serves as the ideal core router, with the 1783-BMS20CA deployed as a managed access layer switch beneath it.
Step 5 — NAT & DMZ Segmentation: If your upgrade includes IT/OT convergence or remote access requirements, the Allen-Bradley 1783-BMS10CGN Stratix 5700 10-Port NAT Switch provides built-in Network Address Translation to isolate OT traffic from corporate networks — a critical security layer during migration.
Step 6 — DeviceNet / EtherNet/IP Gateway: Legacy DeviceNet devices can be retained during the migration phase using the Allen-Bradley 1788-EN2DN/A EtherNet/IP to DeviceNet Gateway Module, bridging your existing DeviceNet field devices onto the new EtherNet/IP backbone without requiring immediate device replacement.
Step 7 — Operator Interface Continuity: Ensure your HMI infrastructure keeps pace with the network upgrade. The Allen-Bradley 2711P-T6M5D8 PanelView Plus 600 connects natively over EtherNet/IP to the 1783-BMS20CA, maintaining operator visibility throughout the cutover window.
Retrofit Guidance FAQ
- Q1: Is the 1783-BMS20CA a direct physical replacement for the 1783-EMS08T (Stratix 6000)?
- The 1783-BMS20CA uses the same DIN-rail mounting standard and 24 VDC power input as the Stratix 6000 family. Physical dimensions differ slightly due to the higher port count; verify panel cutout depth (≥ 60 mm) before installation. No new cable runs are required for copper ports.
- Q2: Can I import my existing Stratix 6000 configuration into the 1783-BMS20CA?
- Rockwell Automation's Device Configuration Service (DCS) supports configuration migration between Stratix generations. Export your current switch configuration via RSLogix 5000 / Studio 5000, then import into the 1783-BMS20CA template. VLAN IDs, port assignments, and QoS policies are preserved in most cases.
- Q3: What firmware version is required for DLR support on the 1783-BMS20CA?
- Device Level Ring (DLR) requires firmware v15.x or later. All units shipped by IndCtrlHub are pre-verified for current firmware compatibility. Contact our technical team for firmware upgrade assistance at no additional charge within the warranty period.
- Q4: Will the 1783-BMS20CA fit in the same panel space as a Stratix 2000 16-port switch?
- The Stratix 5700 chassis is slightly deeper than the Stratix 2000. Verify a minimum panel depth of 65 mm. Width on DIN rail is comparable. No additional DIN rail hardware is required.
- Q5: How do I handle IP address conflicts during the cutover?
- We recommend a staged cutover: configure the 1783-BMS20CA offline with the target IP scheme, then perform a maintenance-window swap. The Allen-Bradley 1786-CTK ControlNet Media Toolkit provides network diagnostic utilities to verify connectivity before and after the swap.
- Q6: What programming tools are needed to configure the 1783-BMS20CA?
- Configuration is performed via Studio 5000 Logix Designer (v21 or later) or the Stratix web interface. No additional programming hardware is required beyond your existing Logix programming terminal.
