AMBLER, Pa., 17 Oct. 2010. MEN Micro Inc. in Ambler, Pa., is introducing the RS3 managed rugged Ethernet switch and the RS4 unmanaged Ethernet switch, each built using a durable aluminum housing and M12 connectors with eight Fast Ethernet ports per switch. The switches are for harsh-environment, mobile, and mission-critical applications such as industrial automation, trains, and construction machines.

The maintenance-free, fanless RS3 and RS4 restore themselves on their own, so if a link is temporarily unavailable, frames are sent via backup/redundant links to avoid data loss. A built-in test mechanism is included. Each switch supports full- and half-duplex operation with auto-negotiation and high-speed non-blocking store-and-forward switching. Quality of Service (QoS) with four traffic classes IEEE 802.1p and three-level 802.1x security are also supported.

The managed RS3 includes the logical segmentation of ports (802.1q VLANS). The RS4 uses an application-specific EEPROM to provide managed switch functionality, such as 802.1p priority as well as port based priority and VLAN or IEEE 802.1q IDs, with fixed settings. Both models have a service port to give authorized users simple configuration options: via a web interface, CLI, SNMP version 3 or exterior dongle for the RS3, and via an SPI for the RS4.

The aluminum housing of the convection-cooled switches measures 220-millimeter-by-130-millimeter-by-70-millimeter. Operating temperature is -40 to 70 degrees Celsius. The switches comply with EN 50155 class Tx and are e1 certified. Because there are no socketed components, the RS3 and RS4 withstand substantial shock and vibration.
