Features:
- Five RJ45 ports connect copper Industrial Ethernet nodes at 10 or 100 Mbit/s.
- Three SC multimode ports carry 100 Mbit/s Ethernet over optical plant segments.
- Managed Layer 2 functions provide VLAN, prioritization, diagnostics, and redundant network recovery.
Siemens 6GK5205-3BD00-2AB2 forwards traffic between copper and multimode optical links in one switch fabric.
Redundant power feeds on 6GK5205-3BD00-2AB2 separate supply continuity from the signaling contact used for fault reporting.
Management services on 6GK5205-3BD00-2AB2 expose port status, topology, and security settings to commissioning tools.
The Siemens 6GK5205-3BD00-2AB2 SCALANCE XB205-3 Managed Industrial Ethernet Switch may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Mixed-Media Ethernet Ports
- RJ45 group: Five auto-negotiating copper ports connect 10/100 Mbit/s Ethernet devices.
- Fiber group: Three SC ports use multimode optical media at 100 Mbit/s.
- Forwarding path: The store-and-forward switch checks received frames before transmitting them to the destination port.
- Media planning: Fiber type, connector condition, and optical budget must match each optical segment.
VLAN, Priority and Access Control
- VLAN separation: IEEE 802.1Q settings divide the physical port set into configured logical networks.
- Traffic priority: Quality-of-service rules move time-sensitive frames ahead of lower-priority traffic.
- Port controls: Port configuration and diagnostics expose speed, duplex, link state, and error conditions.
- Secure management: SNMPv3 and SSH protect supported monitoring and command-line access.
Power and Network Recovery
- Supply paths: Two 24 V DC inputs allow independent power feeds to the switch.
- Fault output: The two-pole signaling contact reports configured supply or port conditions.
- Ring control: MRP and HRP manage supported industrial ring topologies.
- Tree recovery: RSTP and STP prevent or recover from configured Layer 2 loops.
Commissioning and Cabinet Limits
- Engineering routes: Web management, CLI, STEP 7, and TIA Portal provide configuration access.
- Rail mounting: The enclosure mounts on standard or S7-300 rail systems.
- Operating range: The switch operates from 0 to 60 °C under the documented installation conditions.
- Moisture limit: Relative humidity may reach 95 percent only without condensation.
