FREMONT, Calif., 1 March 2008. Elma Bustronic Corp. in Fremont, Calif., is offering second-generation AdvancedTCA backplanes with routing implemented for radial Intelligent Platform Management Bus (IPMB) signals, which provide dual-segment access to every IPM controller even when only one shelf manager is present or operational.

This is an important option for AdvancedTCA systems (related product) to provide higher reliability and redundancy. The backplanes also feature 14-slots with a Dual Star routing topology.

Bustronic uses the AMC female connector, used in MicroTCA and other form factors, as the shelf manager connectors 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-inch 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 AdvancedTCA backplanes are also available. The lead-time is 4-6 weeks ARO. For more information contact Elma Bustronic online at www.bustronic.com.
