Siemens RUGGEDCOM RuggedSwitch A6X30077303 RS900G 8-Port Fully Managed Ethernet Switch With Gigabit Uplinks, 1000LX Singlemode 1310 nm 25 km Interface, 5.6 Gbps Switching, 2 MB Memory, eRSTPIGMPSNMPSNTPSFTP Protocol

The RUGGEDCOM® RS900G is an industrially hardened, fully managed Ethernet switch providing dual fiber optical gigabit Ethernet ports and 8 fast Ethernet copper ports. Designed to operate reliably in harsh industrial environments, the RUGGEDCOM® RS900G provides a high level of immunity to electromagnetic interference and heavy electrical surges typical of environments found in electric utility substations, factory floors or in curb side traffic control cabinets. An operating temperature range of -40 to 85 deg C (-40 to 185 deg F) coupled with hazardous location certification (class I, division 2), optional conformal coating and a powder coated aluminum enclosure allows the RUGGEDCOM® RS900G to be placed in almost any location. The embedded RUGGEDCOM® ROS (Rugged Operating System) 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.
