More Information

Overview Manuals Port Architecture Fault Monitoring Ring Redundancy Configuration Storage

Features:

  • Twelve RJ45 access ports and two long-distance single-mode fiber ports form one managed Ethernet switch.
  • Two 24 V DC inputs provide the redundant supply path monitored by the device fault system.
  • Ring redundancy, PROFINET IO diagnostics, web management, and optional C-PLUG storage support network operation.
Siemens 6GK5212-2BC00-2AA3 switches copper and fiber traffic as the SCALANCE X212-2LD in the X-200 family.

The configurable fault mask links selected port and supply states to the fault LED and signaling contact.

DIN-rail, S7-300-rail, and wall mounting options place the IP30 switch inside the documented enclosure environment.

The Siemens 6GK5212-2BC00-2AA3 SCALANCE X212-2LD Managed Industrial Ethernet Switch may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

All prices are shown in USD.

Copper Access and Optical Uplink Paths

  • Access layer: Twelve electrical ports connect local 10/100 Mbit/s Ethernet devices.
  • Optical layer: Two LD ports carry 100 Mbit/s traffic over single-mode fiber.
  • Connector split: RJ45 connectors serve copper links while BFOC/ST connectors terminate the fiber paths.
  • Status view: Individual port LEDs distinguish link presence, data reception, and fault-mask display.

Stored Fault Mask and Signaling

  • Selected monitoring: The front button records which port states belong to the fault mask.
  • Supply supervision: Both power inputs are monitored when both are present as the mask is saved.
  • Local indication: A detected monitored fault lights the red fault LED.
  • External indication: The floating signaling contact opens at the same time as the fault indication.

Redundancy-Manager Operation

  • Default ring ports: The documented X212-2LD ring pair is available for a closed Ethernet ring.
  • Normal state: The redundancy manager separates its two ring paths while the remaining ring is intact.
  • Interrupted state: A detected break causes the manager to connect the two paths and restore an end-to-end line.
  • Mode display: The RM LED distinguishes enabled, switched-over, and disabled redundancy states.

Management and C-PLUG Handling

  • Browser access: Web-based management provides the documented network-configuration interface.
  • Automation view: PROFINET IO device operation exposes switch diagnostics to a configured controller.
  • Removable record: An optional C-PLUG stores device configuration separately from the switch electronics.
  • Power boundary: The C-PLUG is inserted or removed only while switch power is off.
Description
Siemens 6GK5212-2BC00-2AA3 is the SCALANCE X212-2LD managed Industrial Ethernet switch in the X-200 family. It switches Ethernet traffic through twelve 10/100 Mbit/s electrical ports and two 100 Mbit/s long-distance single-mode fiber ports identified for the X212-2LD configuration.

The mixed-media layout of 6GK5212-2BC00-2AA3 keeps local copper connections and optical uplinks on one managed switch. The two fiber channels use BFOC/ST connections, while the electrical ports provide the RJ45 access path; port LEDs report link and receive activity for the assembled network.

Fault handling on 6GK5212-2BC00-2AA3 combines a configurable fault mask, a red fault LED, and a floating signaling contact. The mask can monitor selected ports and both connected 24 V DC supply inputs, and the stored monitoring selection remains in effect after a power cycle.

For ring operation, 6GK5212-2BC00-2AA3 can act as the redundancy manager and uses its ring ports to restore a connected line when a ring segment is interrupted. Web-based management, PROFINET IO device operation, network management functions, and optional C-PLUG configuration storage provide the documented configuration and service paths.

Installation of 6GK5212-2BC00-2AA3 is supported on a DIN rail, an S7-300 standard rail, or a wall. The switch accepts redundant 24 V DC inputs within 18 to 32 V DC, operates from 0 to 60 °C, and carries an IP30 enclosure rating for cabinet installation.

Technical notes
Siemens 6GK5212-2BC00-2AA3 is the X212-2LD ordering code with twelve electrical ports and two long-distance single-mode fiber ports. Its X-200 management functions cover fault masking, redundancy, and PROFINET IO diagnostics.

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.
How are copper and fiber connections separated on Siemens 6GK5212-2BC00-2AA3?
Siemens 6GK5212-2BC00-2AA3 provides twelve 10/100 Mbit/s RJ45 electrical ports for local links and two 100 Mbit/s BFOC/ST ports for long-distance single-mode fiber.
Why does Siemens 6GK5212-2BC00-2AA3 report a power fault when one supply is still present?
Siemens 6GK5212-2BC00-2AA3 can monitor both redundant 24 V DC inputs through its stored fault mask; loss of either monitored source lights the fault LED and opens the signaling contact.
Which setup step enables ring recovery on Siemens 6GK5212-2BC00-2AA3?
Siemens 6GK5212-2BC00-2AA3 must have the intended ring ports and redundancy-manager mode configured; the RM LED then shows whether the manager is enabled or has switched over.
Does the port-monitoring selection survive a power cycle on Siemens 6GK5212-2BC00-2AA3?
Yes. The fault-mask selection stored by Siemens 6GK5212-2BC00-2AA3 is retained after the switch is powered off and on.
How can configuration data be kept separate from Siemens 6GK5212-2BC00-2AA3 electronics?
An optional C-PLUG stores the configuration of Siemens 6GK5212-2BC00-2AA3 on removable media; it must be inserted or removed only with power switched off.
What enclosure planning is required for Siemens 6GK5212-2BC00-2AA3?
Siemens 6GK5212-2BC00-2AA3 is an IP30 switch for DIN rail, S7-300 rail, or wall mounting, so the cabinet must maintain the documented temperature, humidity, clearance, and ingress-protection conditions.
