        More Information

        Overview Manuals Ports Redundancy Diagnostics Mounting

        Features:

        • Four RJ45 ports connect electrical 10/100 Mbps network links.
        • Two ST/BFOC ports connect 100 Mbps single-mode optical links.
        • A separate fault contact presents an electrical alarm signal.
        The SCALANCE X204-2LD places copper and optical interfaces in one managed switching device, so the network plan can assign each medium to the appropriate run.

        Its redundant supply connection is separate from the signaling contact: the former feeds the electronics and the latter communicates a fault condition to external circuitry.

        Network status can be examined through port diagnostics and management access, while the optional C-PLUG provides removable configuration storage.

        The Siemens 6GK5204-2BC10-2AA3 SCALANCE X204-2LD Managed Switch may still be available for purchase and support from Apter Power beyond End-Of-Life (EOL) by the manufacturer (OEM).

        Copper and Optical Paths

        • Electrical path: RJ45 connections accept copper Industrial Ethernet links from local network devices.
        • Optical path: ST/BFOC connections carry the single-mode fiber links of the LD configuration.
        • Media distinction: The RJ45 and BFOC connectors require different cable and termination arrangements.
        • Switching role: Traffic passes between the electrical and optical network segments through the managed switch.

        Supply and Ring Functions

        • Supply terminals: The four-pole block accepts the redundant DC power connections.
        • MRP: Media Redundancy Protocol can operate with the integrated redundancy-manager function.
        • HRP: High-Speed Redundancy Protocol also has a redundancy-manager function on this switch.
        • Separate functions: Ring redundancy concerns network paths, whereas the redundant supply concerns device power.

        Fault and Management Signals

        • Alarm circuit: The two-pole signaling contact is separate from the copper and fiber traffic ports.
        • Port checks: Port diagnostics and error statistics expose link-related conditions to the administrator.
        • PROFINET: PROFINET IO diagnosis provides device information within a configured PROFINET network.
        • Access methods: Web-based management and CLI offer two configuration paths.

        Cabinet Fit and Conditions

        • Rail option: A 35 mm DIN rail or S7-300 rail can hold the compact switch.
        • Wall option: Wall mounting is listed as an alternative fastening method.
        • Ingress rating: IP30 applies to the device housing, not an enclosure around it.
        • Climate: Operation is specified from -40 to +60 °C with non-condensing humidity up to 95% at 25 °C.
        Description
        Siemens 6GK5204-2BC10-2AA3 is a SCALANCE X204-2LD managed Industrial Ethernet switch for connecting copper network devices with single-mode fiber links. The four RJ45 ports carry local electrical traffic, while the two BFOC ports extend that network over optical paths.

        On 6GK5204-2BC10-2AA3, the optical ports use the LD single-mode configuration; they are not the multimode ports of the X204-2 variant. Copper and fiber connections therefore serve different cable media within one managed switch, and the fiber connectors must be matched to the intended single-mode path.

        Power enters 6GK5204-2BC10-2AA3 through a four-pole terminal block with a redundant 24 V DC supply connection. A separate two-pole signaling contact reports a fault condition; it is an alarm circuit rather than an Ethernet data port.

        For administration, 6GK5204-2BC10-2AA3 offers web and command-line management, port diagnostics, and PROFINET IO diagnostics. An optional C-PLUG holds removable configuration data, while the switch's 35 mm DIN-rail, wall, and S7-300-rail mounting options determine how it is secured in the cabinet.

        Technical notes
        Siemens 6GK5204-2BC10-2AA3 combines four 10/100 Mbps RJ45 connections with two 100 Mbps single-mode BFOC connections for a managed Industrial Ethernet network. Its fault contact and redundant 24 V DC input serve separate signaling and supply roles.

        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.
        VIEW ALL FAQS
        Which fiber type belongs to Siemens 6GK5204-2BC10-2AA3 rather than the X204-2 multimode variant?
        Siemens 6GK5204-2BC10-2AA3 is the X204-2LD version with two 100 Mbps single-mode ST/BFOC ports; the copper side uses four RJ45 ports.
        Can an Ethernet cable be connected to the fault-contact terminals of 6GK5204-2BC10-2AA3?
        No. The 6GK5204-2BC10-2AA3 fault contact is a separate two-pole electrical signaling output, not an RJ45 data connection.
        For 6GK5204-2BC10-2AA3, what is the difference between redundant power and ring redundancy?
        Redundant 24 V DC inputs feed the 6GK5204-2BC10-2AA3 electronics; MRP and HRP concern the network ring path.
        Is a C-PLUG required before 6GK5204-2BC10-2AA3 can be identified as the X204-2LD switch?
        An optional C-PLUG stores removable configuration data for 6GK5204-2BC10-2AA3; it is not part of the model designation.
        Would a load above 0.1 A fit the 6GK5204-2BC10-2AA3 fault-contact rating?
        The 6GK5204-2BC10-2AA3 signaling contact is rated for a maximum of 0.1 A at 24 V DC; a load beyond that rating must not be connected directly.
        Does Siemens specify S7-1500-rail fastening for 6GK5204-2BC10-2AA3?
        For 6GK5204-2BC10-2AA3, Siemens lists 35 mm DIN-rail, wall, and S7-300-rail fastening, but not S7-1500-rail fastening.
