Introduction
The RUGGEDCOM RS940G is an industrially hardened, fully managed Ethernet switch providing six or eight
ports of Gigabit Ethernet. Six 10/100/1000Base-TX triple speed copper ports are standard. An additional two
gigabit fiber or copper ports can be added. The RUGGEDCOM RS940G provides a cost effective way of
connecting a cluster of field devices to a Gigabit Ethernet backbone.
Designed to operate reliably in harsh industrial environments the RUGGEDCOM RS940G provides a high level
of immunity to electromagnetic interference and heavy electrical surges typical of environments found in electric
utility substations, process control or in curb side traffic control cabinets. An operating temperature range of -40 to
85 °C (-40 to 185 °F) coupled with hazardous location certification, optional conformal coating and a galvanized
steel enclosure allows the RUGGEDCOM RS940G to be placed in almost any location.
The embedded Rugged Operating System (ROS) provides advanced networking features such as Enhanced
Rapid Spanning Tree (eRSTP), Port Rate Limiting and a full array of intelligent functionality for high network
availability and manageability. The versatility and wide selection of fiber optics allows the RUGGEDCOM RS940G
to be used in a variety of applications. The RUGGEDCOM RS940G provides two fiber optical Gigabit Ethernet
ports for creating a fiber optical backbone with high noise immunity and long haul connectivity.
The embedded Rugged Operating System (ROS) provides advanced layer 2 and layer 3 networking functions,
and advanced cyber security features. Coupled with the ruggedized hardware design, RUGGEDCOM RS940G
is ideal for creating mission-critical, real-time, control applications where high reliability and availability is of
paramount importance.
