Features:
- Two BusAdapter positions define the connector and transmission medium used by the managed switch.
- Four 10/100 Mbit/s paths support switched Industrial Ethernet and PROFINET traffic.
- Redundant DC inputs, a signaling contact, and port diagnostics expose supply and network conditions.
Siemens 6GK5204-2AA00-2YF2 separates the switch electronics from the removable media interfaces selected for each installation.
Frames entering 6GK5204-2AA00-2YF2 are forwarded through the configured electrical or optical BusAdapter paths.
Management and redundancy functions on 6GK5204-2AA00-2YF2 control topology recovery without changing the connected device protocol.
The Siemens 6GK5204-2AA00-2YF2 SCALANCE XF204-2BA DNA Managed Industrial Ethernet Y-Switch may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Media Selection and Port Formation
- Base unit: The switch electronics are supplied without a fitted network connector.
- Adapter positions: Two BusAdapter slots determine the electrical or optical media available to the four switched paths.
- Selection check: The adapter type, remote interface, cable, and link distance must describe the same medium.
- Replacement scope: A base-unit exchange does not remove the need to verify both installed BusAdapters.
Managed Layer 2 Functions
- Device identity: DCP assigns the PROFINET station parameters used by the engineering project.
- Topology view: LLDP reports neighboring devices and the port relationship seen by management.
- Ring recovery: HRP or MRP controls the documented alternate path after a ring link changes state.
- Traffic review: Port statistics and mirroring expose packet activity without converting the switch into a router.
Redundant Supply and Fault Output
- Dual feeds: Two 24 V DC inputs supply one switch and allow monitoring of each source path.
- Signaling contact: The floating output passes a configured fault state to the cabinet control circuit.
- Local indication: Front LEDs distinguish supply, device, and port conditions before detailed diagnostics are opened.
- Input protection: The supply input includes the documented non-replaceable 2.5 A protection.
Cabinet and Environmental Boundaries
- Rail mounting: The unit attaches to a 35 mm DIN rail rather than an S7 mounting rail.
- Enclosure: IP20 construction requires installation inside a suitable industrial cabinet.
- Temperature: The conformal-coated switch is specified for operation from -40 to 70 °C.
- Humidity: Operation permits up to 95% relative humidity at 25 °C without condensation.
