Siemens SCALANCE X-300 Series Managed Industrial Ethernet Switches
The Siemens SCALANCE X-300 series is a family of managed Industrial Ethernet switches designed for high-performance plant networks, control-level communication and industrial aggregation applications. The series combines Gigabit Ethernet, flexible copper and fiber connectivity, industrial redundancy and network-management capabilities for demanding automation infrastructures.
Unlike the SCALANCE X-100 unmanaged family, the SCALANCE X-300 portfolio is designed for managed industrial networking. Siemens offers compact and rackmount configurations, allowing the series to be deployed in control cabinets, industrial network aggregation points and 19-inch rack environments.

High-Performance Industrial Networking
The SCALANCE X-300 series is intended for industrial networks where higher bandwidth, network availability and managed functionality are required. Siemens positions the family for connecting machines, controllers and field devices at the control and aggregation level of modern production networks.
The portfolio supports Gigabit Ethernet on the traditional X-300 variants, while newer compact XC/XCM/XCH-300 configurations extend performance up to 10 Gbit/s. This makes the family suitable for networks carrying higher-volume industrial data and for infrastructure that needs additional bandwidth for future expansion.

| SCALANCE XC-300 / XCM-300 | Compact high-performance Industrial Ethernet switching for plant and aggregation networks. |
| SCALANCE XCH-300 | Compact high-end switching for demanding high-performance industrial networks. |
| SCALANCE XR-300 / XRM-300 | 19-inch rackmount switching for scalable control and aggregation networks. |
| SCALANCE XRH-300 | High-end rackmount configurations for demanding industrial network architectures. |
| SCALANCE XR-300WG | Cost-optimized, space-saving 19-inch Work Group switching for industrial control cabinets. |
Copper, Fiber and SFP Connectivity
A major advantage of the SCALANCE X-300 portfolio is its broad range of physical interfaces. Depending on the model, users can select RJ45 copper ports, integrated ST/BFOC or SC fiber interfaces, or SFP-based optical connections.
Traditional SCALANCE X-300 configurations can provide up to 20 RJ45 ports and 4 optical ports, while the wider XC/XCM/XCH-300 portfolio provides configurations reaching up to 28 Gigabit ports and higher-speed interfaces. Optical versions can support long-distance communication when the appropriate Siemens fiber transceiver and fiber infrastructure are selected.
Industrial Redundancy and Network Availability
Network availability is a central feature of the SCALANCE X-300 platform. Applicable models support Media Redundancy Protocol (MRP) for redundant ring networks, while selected rackmount variants support additional mechanisms including MRP Interconnection and RSTP+.
These redundancy functions allow industrial networks to be designed with resilient line, ring and star structures. If a network path fails, the redundancy architecture can help maintain communication without requiring a complete network shutdown.
Managed Layer 2 Networking
SCALANCE X-300 switches provide managed Industrial Ethernet functionality, including VLAN and Quality of Service (QoS). VLANs can be used to segment industrial traffic, while QoS helps prioritize important communication flows across shared Ethernet infrastructure.
Siemens also provides configuration through supported web-based management and CLI interfaces, while diagnostics can be accessed through device LEDs, web-based management and network-management systems such as SNMP with SINEC NMS. The SCALANCE portfolio can also integrate with Siemens engineering environments including STEP 7 and PCS 7/PCS neo where supported.
PROFINET and EtherNet/IP Integration
The SCALANCE X-300 family is designed for industrial communication environments using PROFINET and EtherNet/IP. Applicable variants provide integrated industrial protocol diagnostics, helping engineers monitor network status and simplify commissioning and troubleshooting.
The exact industrial protocol features depend on the selected X-300 model and firmware/configuration. Customers should verify the complete Siemens MLFB when a specific PROFINET, EtherNet/IP or diagnostic requirement is involved.
PoE and High-Speed Options
Selected X-300 configurations provide Power over Ethernet, allowing compatible powered devices to receive both data and electrical power through Ethernet cabling. Siemens documentation also identifies X-300 variants with up to two 10 Gbit/s ports and PoE options.
This makes appropriate X-300 models useful for industrial cameras, wireless infrastructure and other Ethernet-powered devices where high-speed uplinks or simplified field cabling are required.
Industrial and Harsh-Environment Applications
The SCALANCE X-300 portfolio is designed for industrial environments and provides selected variants with extended temperature ranges, high EMC resistance and specialized construction for demanding applications. Siemens documentation identifies variants suitable for railway applications and harsh environments, depending on the exact model.
- Industrial automation and factory networking
- Plant-level Ethernet aggregation
- PROFINET Industrial Ethernet networks
- EtherNet/IP industrial networks
- PLC and HMI communication
- Machine and production-line networks
- Industrial fiber-optic backbone connections
- Gigabit industrial network aggregation
- High-bandwidth industrial data networks
- Industrial surveillance and PoE applications
- Transportation and railway networking with applicable variants
Layer 3 Upgrade on Selected Models
Although the SCALANCE X-300 family is primarily positioned as a managed Layer 2 platform, Siemens states that selected XCM/XCH-300 and XRM/XRH-300 switches can be upgraded to Layer 3 functionality through a license. This provides a migration path for applications that later require routing between IP subnets without immediately replacing the hardware.
Compatibility and Model Selection
SCALANCE X-300 is a broad product family rather than one specific switch. Port count, copper/fiber interfaces, Ethernet speed, SFP compatibility, PoE capability, mounting method, power requirements, temperature range and redundancy features vary by exact model.
Customers should therefore provide the complete Siemens MLFB/order number when purchasing. This is particularly important when selecting between XC/XCM/XCH-300 compact models, XR/XRM/XRH-300 rackmount models or XR-300WG configurations.
