6GK6040 - Serial device server with an integrated, managed Ethernet switch

The RuggedServer™ RS400 Family is an industrially hardened, serial device server with an integrated, fully managed, Ethernet switch, designed to operate reliably in electrically harsh and climatically demanding environments.

Featuring an integrated 4 port serial server, a 4 port managed Ethernet switch, and an optional V.90 modem, the RS400 is able to interconnect multiple types of intelligent electronic devices (IEDs) that have different methods of communications.

Using the RS400 results in fewer connectivity devices (which reduces overall system costs) and also extends the useful life of existing legacy IEDs (which minimizes capital expenditure for new equipment).


  • Integrated Ethernet Switch – up to 4 ports
  • High performance and throughput Ethernet switching
  • Fully IEEE 802.3, IEEE 802.3u, IEEE 802.3x compliance
  • Non-blocking, store and forward switching
  • 10/100BaseTX, 10BaseFL, 100BaseFX options
