MEN Mikro F302 - 3U CompactPCI® 8 Port Industrial Ethernet Switch

8x 10/100 Ports, RJ-45 or M12, -40 to +85°C Qualified


The F302 is a managed 3U Fast Ethernet switch module with a maximum of eight channels at the front panel (8 RJ45 or M12 connectors) plus one additional Ethernet channel that is led to the CompactPCI® J1 connector at the rear.

The F302 is managed by its own PowerPC® CPU that integrates the configuration firmware. A service interface is accessible at the front panel, 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.

The F302 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 F302 an even more reliable component in the communication system.

The F302 was 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. There are no socketed components, hardening the card against shock and vibration. The board is ready for coating (standard with M12 connectors) and has a guaranteed minimum standard availability of 5 years.

Depending on the connector type, the F302 has a front-panel width of 12 HP (3 slots) with RJ45 or 16 HP (4 slots) with M12 connectors. In either case the card occupies only one CompactPCI® backplane slot.
