Features:
- Eight RJ45 ports collect local 10/100 Mbit/s Ethernet devices.
- Two 100BASE-FX multimode SC ports continue the network across optical segments.
- Redundant AC/DC inputs and front LEDs expose the switch power and link condition.
Incoming frames are associated with their source port by the unmanaged forwarding logic.
Known unicast traffic leaves through the required copper or fiber interface while broadcast traffic reaches the relevant network segment.
The switch needs no IP configuration, but each physical port and fiber pair retains a defined topology role.
The Siemens 6GK5108-2BD00-2AB2 SCALANCE XB108-2 Switch may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

Collecting eight local Ethernet devices on one unmanaged switch
- RJ45 links: Each port negotiates 10 or 100 Mbit/s communication.
- Address learning: The switch associates source addresses with receiving ports.
- Frame forwarding: Known traffic leaves toward the learned destination.
- Local map: Cable labels keep controller and device connections identifiable.
Extending the same Ethernet network over two optical paths
- SC interfaces: Both ports use multimode 100BASE-FX connections.
- Fiber pair: Transmit and receive strands remain correctly crossed at each link.
- Galvanic separation: Optical media removes the conductive path between locations.
- Topology role: The two links can serve line, star or documented PRP arrangements.
Feeding the switch through two independent supply entries
- Input type: The switch accepts 24 V AC or DC within the documented range.
- Dual paths: Either redundant input can power the internal electronics.
- Protection: Upstream circuits use the recommended 0.6 A fuse boundary.
- Power state: Front indication shows which operating condition is present.
Diagnosing physical links without management software
- Power LED: Supply state is visible at the switch.
- Port LED: Each copper and fiber interface reports its link condition.
- Traffic path: Cable and remote-device tests identify the failed segment.
- Protocol boundary: Class A PROFINET traffic is forwarded without switch parameterization.
