Kontron’s 6U CompactPCI Gbit Ethernet switch for high-end communications is available in three rugged levels. The Kontron CP6923 PICMG 2.16 compliant 6U CompactPCI managed Ethernet switch with 24 link ports and two 10GbE XFP uplink connections 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°C 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. These three versions make the Kontron CP6923 CompactPCI switch an appropriate partner for the Kontron CP6001 CPU board with Intel Core Duo/Core 2 Duo that is also available in the R1, R2 and R3 versions. A functionally validated combination of CPU board and Ethernet switch at each rugged level provides a high degree of routing redundancy and can communicate with each other rapidly over GbE via the CPCI backplane. Together, they are suited for applications that require high-end performance in a wide range of harsh environments, including those found in the military, maritime and aerospace sectors. The Kontron CP6923 CompactPCI switch comes with technologies for non-blocking layer 3 switching and routing and has a 24-port GbE layer 3 switch with 19 link ports to CPCI boards and one link port to second fabric boards (all ports 10/100/1000Base-T). Depending on the rugged level, the board will be equipped with four additional ports on the front panel or on the backplane. Furthermore, two fibre optic 10GbE XFP uplink ports may be provided on the front panel for R1 boards.
