SF3 - Managed 8-port Rugged Ethernet Switch with M12 (Product Discontinued)

The SF3 is a stand-alone, managed industrial Fast Ethernet switch that comes in a compact 3U, 22HP, 19" cassette. It provides eight channels at the front panel accessible through M12 connectors.

It is supplied by its integrated, rugged power supply unit (PSU), with a power connector at the front panel. The entire switch consumes less than 7 W and needs no cooling.

The SF3 is managed by its own PowerPC CPU that integrates the management firmware. A service port is accessible at the front panel on a D-Sub 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 can also 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.

All of the ports are individually configurable. The SF3 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 theSF3 an even more reliable component in the communication system.

In addition, the switch can act as Power over Ethernet (PoE) Power Sourcing Equipment (PSE), supplying other devices on ports 1 and 2 with power.

The SF3 was specifically designed for rugged mobile communication systems with high demands. It is thus for example fully compliant with the EN 50155 railway standard. All components inside the cassette are specified for a -40 to +70°C operation temperature (+85°C for ten minutes according to EN50155 Class Tx). There are no socketed components, hardening the box against shock and vibration. Its PCBs are conformally coated and the switch has a guaranteed minimum standard availability of 5 years.
