Industrial Ethernet 5-port Gigabit Switch
SDW-550-T5G
The SDW-550-T5G is an unmanaged 5 port switch with five copper ports, all supporting 10 Mbit/s, 100 Mbit/s or Gbit 
Ethernet. It is designed for easy use in heavy duty industrial, maritime and rail trackside applications. The unit supports 
802.1Q long packets which allow all standard industrial Ethernet protocols to be used.
The SDW-550-T5G is designed for use in industrial applications with dual 9.6 to 57.6 VDC power input. The unique “tri-
galvanic” isolation provides isolation between all ports, power supply and between each chassis screen avoiding ground 
loop currents. The IP21 rating ensures that the unit can be installed in locations where condensed water may occur.
Only industrial grade components are used which gives the SDW-550-T5G an MTBF of 1.121.000
 
hours and ensures 
a long service life.  A wide operating temperature range of –40 to +74 °C (–40 to +165 °F) can be achieved with no 
moving parts. 
The SDW-550-T5G has been tested both by Westermo and external test houses to meet EMC, isolation, vibration and 
shock standards, all to the highest levels suitable for heavy industrial, trackside and maritime environments.
Network diagnostics are simplified with the inclusion of port mirroring on one port allowing data flow through the switch 
to be monitored using a network analyzer.  All five ports can have data rate and flow control locked by DIP switch, which 
can eliminate problems with old legacy Ethernet equipment that is unable to support auto negotiation.
