Features:
- Eight RJ45 ports connect local copper devices at 10 or 100 Mbit/s.
- Two ST/BFOC ports extend the network through 100BaseFX multimode fiber.
- Redundant 24 V AC/DC inputs maintain the unmanaged switch power path.
Siemens 6GK5108-2BB00-2AB2 forwards copper and optical Ethernet traffic on one unmanaged network.
The fiber interfaces of 6GK5108-2BB00-2AB2 use a separate optical transmit and receive path.
Port indicators on 6GK5108-2BB00-2AB2 support local link and traffic checks.
The complete order number in Siemens 6GK5108-2BB00-2AB2 SCALANCE XB108-2 Unmanaged Industrial Ethernet Switch identifies the configuration that must be checked before product selection or replacement.

RJ45 Device Connections
- Port group: Eight RJ45 sockets attach local industrial Ethernet devices.
- Link rate: Each copper path operates at ten or one hundred megabits per second.
- Cable boundary: Twisted-pair cable category, length, shielding, and connector seating must meet the installed network rules.
- Link diagnosis: Port indicators show whether a physical link and traffic activity are present.
Multimode 100BaseFX Links
- Optical ports: Two ST/BFOC connectors provide multimode 100BaseFX communication.
- Fiber pairing: Transmit on one endpoint connects to receive on the other endpoint.
- Media match: Both devices must use compatible multimode wavelength, connector, and optical-budget specifications.
- Fault isolation: Clean connectors and a light-path test separate fiber loss from switch or network faults.
Two Supply Inputs
- Input role: Each supply input can feed the switch independently when it remains inside the permitted range.
- Redundancy: Loss of one valid feed does not interrupt operation while the second feed remains available.
- AC or DC: The terminal arrangement supports the documented 24 V AC or DC supply form.
- Grounding: Protective bonding and cable shielding must follow the cabinet installation plan.
Unmanaged Switching Boundaries
- Frame forwarding: The switch learns and forwards Ethernet traffic without VLAN or routing configuration.
- PROFINET use: Conformance Class A supports the documented basic PROFINET network role.
- Redundancy role: Media Redundancy Protocol support must be applied only within a compatible ring design.
- Cabinet fit: The DIN-rail IP20 unit requires an enclosure with suitable clearance and temperature control.
