Rugged Ethernet Switch Boards Roundup
cPCI Ethernet Switch Offered in Three Rugged Levels The concept of EOIP (Everything Over IP) is catching on strong in the military. Voiceover-IP networks aboard aircraft carriers, for example, are one step in that direction. Cost is a factor in such network implementations. With that in mind, Kontron’s CP6923 board provides built-in switching capabilities for cPCI installations at an unmatched price-toperformance ratio by implementing the latest technologies including the highly compact Broadcom BCM56502 Gigabit Ethernet switch chip. The Kontron CP6923 is a 6U hotswappable cPCI switch with 24 Gbit Ethernet ports and two high-capacity uplinks (10GbE), which makes systems cascadable. It supports all relevant standards in carrier-grade L2 and L3 switching, routing, VLANs and QoS (Diffserv) developed by Kontron.
The Kontron CP6923 now comes in three rugged levels defined as R1, R2 and R3. The R2 and R3 versions are available with E2 capabilities (extended temperature range from -40° to + 85°C). The R1 version is designed for standard application requirements in air-cooled environments. The R2 version is ruggedized for higher shock and vibration environments in accordance with the EN60068-2-27/64 (similar to VITA 47’s EAC6) specification. The R3 version is fully conduction-cooled and meets VITA 47’s ECC4 requirements.

8-Port Ethernet Switches Boast Rugged Design Low-power, fanless electronics are a must in many harsh-environment military applications. MEN Micro 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. Consuming less than 7W 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 halfduplex operation, high-speed non-blocking, store-and-forward switching and autonegotiation 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. Pricing per unit for the unmanaged switches is $1,325, and $1,769 for managed.
