More Information

Overview Manuals Port Topology Redundancy Modes Management Access Diagnostic Paths

Features:

  • Twelve 10/100 copper ports and two 100BaseFX multimode ports share one managed switch.
  • Ring and parallel-network functions support HRP, MRP and PRP topology planning.
  • A removable C-PLUG can retain the managed configuration outside the switch electronics.
The X212-2 joins local RJ45 equipment to ST/BFOC fiber segments without using external media converters at the node.

Management access through STEP 7, a browser or the command line exposes port state and network diagnostics at different operating levels.

Two DC feeds and a separate signaling contact divide supply continuity from external fault reporting.

Siemens 6GK5212-2BB00-2AA3 SCALANCE X212-2 Managed Industrial Ethernet Switch Manuals, Datasheets, Links Important Notice: Other accessories, manuals, cables, calibration data, software, etc. are not included with this equipment unless listed in the above stock item description. All prices are shown in USD.

Combining copper access with a fiber backbone

  • Copper Edge: Twelve RJ45 connections serve local 10/100 Mbit/s Industrial Ethernet devices.
  • Optical Uplink: Two ST/BFOC interfaces extend the switch fabric over 100BaseFX multimode fiber.
  • Media Boundary: The optical ports are fixed fiber interfaces rather than plug-in single-mode or LC transceiver slots.
  • Link Observation: Port statistics and status reporting help separate a local copper fault from an optical-segment fault.

Choosing the recovery structure for the network

  • HRP Ring: The switch can participate in a high-speed redundancy ring and perform the documented manager role.
  • MRP Ring: Media Redundancy Protocol offers the PROFINET-oriented ring path for compatible nodes.
  • PRP Network: Parallel Redundancy Protocol connects the switch into duplicated LAN structures without using the ring manager function.
  • Mode Selection: The selected redundancy scheme must match the rest of the network rather than being enabled as an isolated switch setting.

Three ways to reach the switch configuration

  • Engineering Access: STEP 7 integrates SCALANCE configuration into the automation project.
  • Browser Access: Web-based management presents settings and status through an Ethernet session.
  • Command Line: The CLI provides a text-based path for managed-switch configuration and inspection.
  • Stored Setup: A C-PLUG can carry the saved configuration when the removable medium is installed.

Tracing faults from alarm to individual port

  • Signal Contact: The terminal contact reports a configured fault to an external alarm circuit.
  • Port Counters: Packet, size and error statistics narrow a communication issue to the affected interface.
  • Network Reporting: SNMP and PROFINET diagnostics transfer switch state to supervisory and engineering tools.
  • Topology Discovery: LLDP identifies neighboring devices and helps verify the physical connection map.
Description
Within a SCALANCE industrial network, Siemens 6GK5212-2BB00-2AA3 acts as an X212-2 managed switch for connecting copper devices and multimode fiber segments. Its switching plane combines twelve 10/100 Mbit/s RJ45 ports with two 100BaseFX ST/BFOC ports.

The port arrangement on 6GK5212-2BB00-2AA3 lets local electrical links and longer optical paths meet at one managed node. A signaling contact reports faults outside the data path, while the redundant 24 V supply inputs keep the power feeds separate from network traffic.

Commissioning 6GK5212-2BB00-2AA3 can use STEP 7, the command-line interface or web-based management. These access paths configure the same switch while serving engineering, browser and text-console workflows.

Port diagnostics on 6GK5212-2BB00-2AA3 separate link state from packet and error statistics. SNMP, LLDP and PROFINET IO diagnostics then carry different views of that state to network and automation tools.

For resilient topology design, 6GK5212-2BB00-2AA3 supports HRP and MRP ring operation with an integrated redundancy manager, and it can participate in a PRP network. An optional C-PLUG provides removable configuration storage for the managed-switch setup.

Technical notes
For Siemens 6GK5212-2BB00-2AA3, the optical interfaces are multimode ST/BFOC ports; LC and single-mode transceivers are not part of this layout.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Which fiber connector must be matched to Siemens 6GK5212-2BB00-2AA3?
Siemens 6GK5212-2BB00-2AA3 uses two fixed ST/BFOC multimode 100BaseFX ports, so an LC or single-mode patch lead is not a direct match.
Why are there two 24 V supply inputs on 6GK5212-2BB00-2AA3?
The two inputs let 6GK5212-2BB00-2AA3 receive redundant DC feeds; they do not create two independent switching sections.
Should HRP, MRP and PRP all be enabled together on 6GK5212-2BB00-2AA3?
No. The topology around 6GK5212-2BB00-2AA3 determines whether the installation uses an HRP ring, an MRP ring, or a PRP parallel network.
What problem does the C-PLUG solve for 6GK5212-2BB00-2AA3?
A C-PLUG stores the managed configuration of 6GK5212-2BB00-2AA3 on removable media, keeping those settings separate from the installed switch electronics.
Where can an engineer configure 6GK5212-2BB00-2AA3 without using STEP 7?
6GK5212-2BB00-2AA3 also provides web-based management and a command-line interface for supported configuration and diagnostic tasks.
How can a technician isolate a port fault on 6GK5212-2BB00-2AA3?
Start with the signaling contact and port state, then use the packet and error counters of 6GK5212-2BB00-2AA3 to identify the affected link.
