The SCALANCE XR-300PoE Industrial Ethernet switches are partly modular, high-performance, industry-standard switches for the construction of electrical and/or optical line, ring and star topologies at data transfer rates of 10/100/1000 Mbit/s, designed for installation in 19" control cabinets

• As many as 24 electrical and/or optical interfaces (10/100/1000 Mbit/s), of which 16 are integrated RJ45 ports, eight of which are PoE-compatible;
  up to four electrical and/or optical 2-port media modules can additionally be inserted in the media module slots of the basic unit
• High-speed media redundancy through integral redundancy manager both for Gigabit Ethernet (with SCALANCE X-300, X-400) and Fast Ethernet (e.g. in combination with SCALANCE X-200 switches)
• Seamless integration of automation networks into existing corporate networks thanks to support for a host of IT standard functions (VLANs, IGMP-Snooping/Querier, STP/RSTP, Link Aggregation, Quality of Service)
• Redundant integration into higher-level networks thanks to support for standardized redundancy procedures (Spanning Tree Protocol/Rapid Reconfiguration Spanning Tree Protocol/MRP)
• Remote diagnostics by means of PROFINET diagnostics, Web browser, CLI, or SNMP
