Intelligent 8-port Fast Ethernet Switches from Men Micro feature connection flexibility and rugged design.

Men Micro Inc. now offers a line of intelligent 8-port fast ethernet switches that provides three types of front connections (RJ45, M12 and D-Sub) and a rugged design for use in a wide array of harsh environments.

Consuming less than 7 W per switch and packaged in a fanless housing, the new SF series of Ethernet switches offers an exceptional combination of ruggedness, low power and flexibility that make these switches ideal for mobile, transportation and automation applications. Specific models include the SF1, SF2, SF3 and SF4.

All switches support full-duplex and half-duplex operation, high-speed non-blocking, store-and-forward switching and auto-negotiation as well as layer-2 switching. They are fault tolerant and restore themselves on their own: if a link is temporarily unavailable, the switches will work again after the disturbance without any restart or reset. A built-in test mechanism makes these rugged Ethernet switches reliable components within an embedded system.

The four switches in the new SF series come in both managed (SF2 and SF3) and unmanaged (SF1 and SF4) versions, as well as in stand-alone or 19-inch rack-mountable configurations. The managed switches support power over Ethernet (PoE) on ports 0 and 1, can act as power source equipment (PSE) or a powered device (PD) and include an FPGA-based low power CPU that integrates the management software.

All of the ports are individually configurable. For managed switches, a service interface is accessible at the front panel, providing an easy way to configure the switch using an SMB interface on a standard D-Sub connector. For the unmanaged switches, Men Micro also provides 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.
