Managed SCALANCE X204-2 connectivity for mixed copper and multimode fiber industrial Ethernet cells.
Siemens 6GK5204-2BB00-2AA3 is a SCALANCE X204-2 managed Industrial Ethernet switch. It combines four 10/100 Mbps RJ45 interfaces with two 100 Mbps multimode BFOC fiber interfaces, supporting PROFINET IO device operation, network management and redundant ring architectures. Procurement should be based on the complete suffix because the installed port media, connector style and lifecycle differ across X204-2 variants.

Apply this exact model only after confirming the installed system, electrical design and project documentation.
Use as a managed distribution point for controllers, HMIs and Ethernet devices in an automation cell.
Bridge local RJ45 equipment to multimode fiber links where distance or EMC conditions favor optical media.
Support ring-based network availability when the installed topology and configuration match the X204-2 design.
| Check point | What to confirm | Procurement note |
|---|---|---|
| Port match | Confirm four RJ45 ports and two multimode BFOC ports are required. | BFOC is not interchangeable with SC, LC or SFP optics. |
| Network role | Verify PROFINET IO device and management functions against the project design. | Check configuration backups before replacement. |
| Power and signaling | Match redundant supply wiring and fault-contact use. | Review terminal assignment before energizing. |
| C-PLUG | Confirm whether an installed C-PLUG must be transferred. | Handle configuration media under plant procedures. |
| Migration | Evaluate official successor 6GK5204-2BB10-2AA3 separately. | Do not assume drop-in replacement without port and firmware checks. |
Siemens identifies 6GK5204-2BB00-2AA3 as PM500:Discontinued Product or end of PLM & Support, effective 16 January 2014. The official successor is 6GK5204-2BB10-2AA3; migration still requires an engineering review.
Four 10/100 Mbps RJ45 ports and two 100 Mbps multimode BFOC fiber ports.
No. Siemens describes it as a managed Industrial Ethernet switch with network-management functions.
Yes, the official description includes operation in a redundant ring. Verify the site configuration and protocol settings.
Yes. Siemens lists it as a PROFINET IO device.
Confirm BFOC fiber media, RJ45 port count, supply wiring, fault contact and any C-PLUG configuration.
