Backplanes meet AdvancedTCA specs

Rittal has released a range of backplanes to coincide with the adoption of the PICMG3.x range of Advanced Telecom Computing Architecture specifications.

Rittal has released a range of backplanes to coincide with the adoption of the PICMG3.x range of Advanced Telecom Computing Architecture specifications.

All ATCA backplane styles currently available are 14-slot versions designed to fit standard 482.6mm (19in) chassis with the increased slot spacing of 6HP (30.5mm) compared with previous standard slot widths of 4HP (20.3mm).

Backplanes are available in the following architectures: dual-dual star only, dual-dual star with single mesh overlay, and full mesh architecture.

The full mesh backplane is a 36-layer Nelco 6000 material PCB and at a recent PICMG Plug-fest a full load test (14 slots at 200W) demonstrated through thermal imaging that its operating temperature is very cool.

The backplanes are suitable for use with PICMG 3.1 for Ethernet fabrics, PICMG 3.2 for InfiniBand, and PICMG 3.3 for StarFabric Interconnect.

To help system developers, Rittal has a developer chassis engineered to meet the mechanical requirements of the ATCA.

The open frame chassis includes cooling with options to use any of the above backplanes for development purposes where access is needed to plug-in boards without lengthening the circuit path.
