MEN Mikro F301 - 3U CompactPCI® 8+1 Port Industrial Ethernet Switch

8x 10/100 Ports Front, 1x 10/100 Rear, -40 to +85°C Qualified


The F301 is an unmanaged 3U Fast Ethernet switch module with a maximum of 8 channels at the front panel (8 RJ45 or 6 D-Sub connectors) and an integrated Fast Ethernet controller. The Ethernet switch is an unmanaged device, meaning that it is not recognized by other CompactPCI® devices thereby removing the need for additional software. As an option it is also available as a fixed managed device, with a customized, hardware-coded configuration.

An onboard Ethernet controller is used to realize the interface to the CompactPCI® bus. The F301 also works without the Ethernet controller being assembled. In this case the CompactPCI® bus only delivers the power supply. As an option (with the Ethernet controller not being assembled) the J2 connector can be assembled and used to manage the rear I/O Ethernet signals from the ninth Ethernet port.

The F301 is specifically designed for rugged mobile communication systems. It is thus, for example, fully compliant with the EN 50155 railway standard. All components on the board are specified for a -40 to +85°C operation temperature. The board is ready for coating.

The F301 needs one slot on the CompactPCI® bus, using a 4 HP or 8 HP front panel.
