Seamless Upgrade Solutions — Migration-Ready Component Ecosystem
A successful Stratix network migration is rarely a single-component swap. When upgrading to the 1783-BMS20CGN, your engineering team should simultaneously evaluate the following companion components to ensure end-to-end compatibility and prevent cascading failures:
- 🔗 Stratix 5700 10-Port Variant: If your topology requires a smaller edge node alongside this 18-port core switch, the Allen-Bradley 1783-BMS10CL Stratix 5700 10-Port Managed Ethernet Switch provides a consistent firmware baseline across your ring or star topology.
- 🔗 Stratix 8000 Uplink Switch: For backbone uplink redundancy, pair this unit with the Allen-Bradley 1783-MS06T Stratix 8000 6-Port Managed Industrial Ethernet Switch to maintain a fully managed, fault-tolerant network spine.
- 🔗 EtherNet/IP Web Server Module: When replacing the switch, verify that your controller's web diagnostics remain accessible via the Allen-Bradley 1768-EWEB EtherNet/IP Web Server Module — critical for remote monitoring post-migration.
- 🔗 CompactLogix EtherNet/IP Controller (1.5MB): Ensure your PLC firmware is current. The Allen-Bradley 1769-L35E CompactLogix 1.5MB EtherNet/IP Controller is fully validated with the 1783-BMS20CGN and supports CIP Sync time coordination.
- 🔗 CompactLogix EtherNet/IP Controller (1MB): For lighter control loads, the Allen-Bradley 1769-L30ER CompactLogix 1MB EtherNet/IP Controller integrates natively with the switch's IGMP snooping and QoS prioritization.
- 🔗 EtherNet/IP Adapter Module: When migrating distributed I/O racks, update the adapter to the Allen-Bradley 1769-AENTR EtherNet/IP Adapter Module to leverage the switch's full bandwidth allocation per port.
- 🔗 EtherNet/IP to DeviceNet Gateway: If your legacy field devices still run DeviceNet, the Allen-Bradley 1788-EN2DN EtherNet/IP to DeviceNet Gateway bridges your old DeviceNet segments into the new EtherNet/IP backbone without rewiring.
- 🔗 FlexLogix ControlNet Daughtercard: For plants retaining ControlNet segments during phased migration, the Allen-Bradley 1788-CNCR FlexLogix ControlNet Daughtercard allows parallel network operation during the transition window.
Retrofit Guidance FAQ
Q1: Is the 1783-BMS20CGN a direct physical replacement for older Stratix 5700 models?
A: Yes. The 1783-BMS20CGN shares the same DIN-rail form factor and power connector pinout as earlier Stratix 5700 variants. Physical installation requires no panel modifications. Verify your existing 24 VDC or 48 VDC supply meets the dual-input spec before powering on.
Q2: Will my existing Logix 5000 program require changes after the switch upgrade?
A: No controller code changes are required. The 1783-BMS20CGN is transparent to the EtherNet/IP application layer. However, if you are enabling CIP Sync or PTP for motion control, update your Studio 5000 project's time synchronization settings accordingly.
Q3: How do I migrate VLAN and QoS configurations from the old switch?
A: Export your existing switch configuration via Cisco IOS CLI (show running-config) before decommissioning. The 1783-BMS20CGN accepts the same IOS command set, allowing direct import of VLAN, RSTP, and QoS policies with minimal editing.
Q4: Can this switch operate alongside legacy unmanaged switches during a phased rollout?
A: Yes. The 1783-BMS20CGN supports mixed-topology operation. Configure the ports connecting to unmanaged segments as access ports with RSTP edge mode to prevent topology change notifications from disrupting the managed network core.
Q5: What fiber SFP modules are compatible with the combo SFP ports?
A: Rockwell-approved SFP modules (1783-SFP1GSX, 1783-SFP1GLX) are recommended. Third-party Cisco-compatible SFPs may also function but are not covered under the 12-month warranty.
Q6: Is wiring polarity critical for the dual redundant power inputs?
A: Yes. Observe correct DC polarity on both power input terminals. Reverse polarity will trigger the internal protection circuit and prevent the unit from powering on. Label both feeds clearly during installation.
