RS3 - Managed 8-port Ethernet Switch (Product Discontinued)

The RS3 is an industrial, IP67 stand-alone Fast Ethernet switch. It is managed and provides eight Ethernet channels on M12 connectors.

The rugged switch supports full-duplex and half-duplex operation with auto-negotiation, high-speed non-blocking store-and-forward switching, Quality of Service (QoS) support with four traffic classes IEEE 802.1p and three-level 802.1x security as well as the logical segmentation of ports (802.1q VLANs). The switch is fault tolerant and restores itself on its own: If a link is temporarily unavailable, frames can be sent via backup/redundant links (spanning tree protocol / link aggregation) and no data loss occurs. Its built-in test mechanisms make the RS3 an even more reliable component in the communication system.

A service port is accessible at the front panel on an M12 connector, providing an easy way to configure the switch. A command line interface is available via the RS232 at the service port and over Ethernet via Telnet or Secure Shell (SSH). The switch canalso be configured via SNMP (version 3). Additionally, the service connector can be used to attach an external dongle to store or update the switch configuration. This makes it easy to exchange the unit for service purposes.

The RS3 a member of the MIPIOS family of extremely rugged IP67 compliant products designed for Ethernet connectivity and highly demanding applications, e.g., for redundancy systems.

The industrial-grade unit is fully compliant with EN 50155 railway standard. All components inside the enclosure are specified for -40 to +85°C operation, thus enabling the device for EN 50155 class Tx operation. Additionally, the device is is compliant with ISO 7637-2 (E-mark for automotive). Convection cooling is sufficient. There are no socketed components, hardening the box against shock and vibration. The internal electronics are prepared for conformal coating.

The Ethernet switch is prepared for wall or DIN-rail mounting.
