Unmanaged industrial switch with twelve Fast Ethernet copper ports and two multimode BFOC fiber ports

SCALANCE X112-2 combines 12 x 10/100 Mbit/s RJ45 ports with two 100 Mbit/s multimode ST/BFOC ports. It provides redundant 24 V DC supply capability, LED diagnostics, a signaling contact and a compact DIN-rail or wall-mount enclosure.

Panel replacement check: Map all 14 ports, verify multimode fiber and BFOC connectors, record redundant power and alarm wiring, confirm the required PRP role and preserve port labels before moving any cable.

Port Plan

Copper, fiber, and redundancy connections must be documented before disturbing the installed switch.

Copper map

Label all 12 RJ45 links with device, port speed, and cable destination.

Fiber map

Confirm multimode fiber, transmit/receive orientation, BFOC condition, and the far-end port.

Power and alarm

Record both 24 V feeds, polarity, and the signaling-contact destination.

DESCRIPTIO

6GK5112-2BB00-2AA3 is the Siemens SCALANCE X112-2 unmanaged Industrial Ethernet switch for mixed copper and 100 Mbit/s multimode fiber networks. The two optical links use ST/BFOC connectors, while 12 RJ45 ports serve local devices.

Because the switch is unmanaged, fault isolation depends on accurate port records, LEDs, the signaling contact, and cable tests. Restore one network path at a time and confirm stable links before closing redundant or PRP paths.

Isolatio defectus

Use link evidence and path-by-path tests before replacing the complete switch.

Dark fiber link

Inspect both BFOC connectors, fiber type, Tx/Rx pairing and far-end power before changing the switch.

Intermittent copper link

Check RJ45 locking, cable routing, shielding and port LEDs while the fault is present.

Redundant path

Open and restore one path at a time under network monitoring to avoid an unintended loop or outage.

Quaestiones Frequentes

How can I verify that 6GK5112-2BB00-2AA3 fits the existing network?

Confirm the exact order number, 12 copper links, two 100 Mbit/s multimode ST/BFOC links, mounting method, 24 V supplies and signaling contact. Record every cable destination before removal.

What fiber compatibility checks are required for 6GK5112-2BB00-2AA3?

Verify multimode fiber, ST/BFOC connectors, transmit and receive pairing, link loss and the far-end optical port. Clean and inspect both ends before concluding that an inactive link is a switch fault.

How should redundant power be wired for 6GK5112-2BB00-2AA3?

Use the documented 24 V DC supply arrangement and terminal-block polarity, and verify both feeds independently. Record the common reference, protective grounding and alarm-contact behavior before commissioning.

Why can an RJ45 port on 6GK5112-2BB00-2AA3 show an intermittent link?

Inspect the connector latch, cable and shield, port LED, connected-device speed and supply stability. Move only the affected cable during diagnosis so the fault can be associated with a port, cable or device.

How should 6GK5112-2BB00-2AA3 be commissioned in a PRP installation?

Confirm the documented PRP topology and network separation, label both redundant paths and restore one side at a time. Monitor duplicates, link state and application communication before reconnecting the second path.

What records should be kept before replacing 6GK5112-2BB00-2AA3?

Serva la completa mappa delle porte, l’orientamento delle fibre Tx/Rx, il cablaggio di alimentazione e allarme, le fotografie del montaggio e lo stato normale dei LED. Questa prova è essenziale perché lo switch non possiede alcun file di configurazione da esportare.
