The SF1, available from Dominion Electronics , is a stand-alone, unmanaged Fast Ethernet switch that comes in a compact 3U, 18HP, 19" cassette. It provides eight channels at the front panel accessible through RJ45 connectors.

The SF1 is supplied by its integrated, rugged power supply unit (PSU), with a power connector at the front panel. The entire switch consumes less than 7W and needs no cooling.

The SF1 supports full-duplex and half-duplex operation, auto-negotiation, and Layer-2 switching. The switch is fault tolerant and restores itself on its own. If a link is temporarily unavailable, it will work again after the disturbance without any restart or reset. Its built-in test mechanisms make the SF1 an even more reliable component in the communication system.

Although the switch is unmanaged, MEN also provide fixed managed versions with a configuration EEPROM tailored to the application's requirements. This may include features such as 802.1p priority and port based priority, port based VLAN or IEEE 802.1q VLAN IDs.

The SF1 was specifically designed for rugged mobile communication systems. It is thus for example fully compliant with the EN 50155 railway standard. All components inside the cassette are specified for a -40 to +85°C operation temperature. There are no socketed components, hardening the box against shock and vibration.
