Switches of the SCALANCE X‑300 product line in the standard version

Electrical and/or optical line, star or ring structures can be implemented with the switches of the SCALANCE X‑300 product line. Switches with Fast Ethernet and/or Gigabit Ethernet ports are available for this purpose.

To increase network availability, as many as 50 linear cascaded switches be configured into a ring (Ethernet with fast media redundancy). All switches of the SCALANCE X‑300 product line can be used as redundancy managers in the ring. As a redundancy manager, a SCALANCE X‑300 switch monitors the SCALANCE X switches connected via its ring ports; it switches bumpless to the substitute route on failure of a transmission route or a switch in the ring. Two rings can also be redundantly linked via the standby function of the SCALANCE X-300 switches.

Several nodes or subnets can be electrically or optically connected with each other by means of a SCALANCE X-300 switch as star point in a star topology.

The switches of the SCALANCE X‑300 product line are available in different designs:

• Compact design
  • Standard version X‑300
  • Partially modular version X‑300 M
• Rack design: Modular rack for installation in 19" control cabinets
  • Standard version XR‑300 M
  • PoE version XR‑300 M PoE (Power over Ethernet)
  • EEC version XR‑300 M EEC (Enhanced Environmental Conditions)
