The new ATCA backplanes have routing implemented for radial Intelligent Platform Management Bus (IPMB) signals. Radial IPBM provides dual segment access to every IPM controller even when only one shelf manager is present or operational. This is an important option for ATCA systems to provide higher reliability and redundancy.
The backplanes also feature 14-slots with a Dual Star routing topology. Bustronic now uses the familiar AMC female connector, used in MicroTCA and other form factors, as the shelf manager connectors. They were chosen because they are widely used, reliable, and offer a high pin count in a small space. The connectors are dense enough to be placed next to the slots (called Slot 0) so that they can fit within a card cage for 19" rackmount systems. These Shmm Edge connectors are stacked on top of each other so that dual shelf managers can be used in the same system, but not take up any slot space.
Mesh topology backplanes are also available in 2, 5, and 14-slot sizes standard. Custom versions of Bustronic's ATCA backplanes are also available. The lead-time is 4-6 weeks ARO.
