Introduction; Feature Highlights - Siemens SIMATIC NET RUGGEDCOM RST2228 Equipment Manual

Introduction

The RUGGEDCOM RST2228 is a utility grade, fully managed, industrial Ethernet
switch designed to operate reliably in harsh environments. With a rugged metal
enclosure and an optional conformal coating, the RUGGEDCOM RST2228 provides a
high level of immunity to electromagnetic interference and heavy electrical surges,
and can withstand extreme temperatures.
Highly modular, the RUGGEDCOM RST2228 switch supports up to 28 electrical and/
or optical interfaces with data transfer rates of 10/100/1000 Mbps. This makes it the
ideal industry-standard switch for constructing electrical and/or optical line, ring, and
star topologies.
The RUGGEDCOM RST2228 switch is supported by RUGGEDCOM ROS, which provides
advanced Layer 2 networking functions, and advanced cyber security features.
