DIOT CompactPCI Serial crate hardware

The 3U crate is a main component of the Distributed I/O Tier hardware kit. The enclosure is assembled using 3U sub-rack components compatible with the IEC 60297-3 and IEEE 1101.10-1996 mechanical standards. These are low-cost aluminum elements available in the products portfolio of all major crate vendors. The crate provides:

  • in-house designed 9 slot backplane compatible with CompactPCI Serial standard
  • support to host Rear Transition Modules (RTMs) - the RTMs are usually fully passive boards that provide an interface with external equipment through a direct RTM connector to the corresponding Peripheral Board
  • two power supply slots (two power backplanes) to host dual modular redundancy power supplies in load-sharing configuration
  • 1U Fan Tray module that can be mounted either below or above the main 3U crate

The whole project is licensed under CERN OHLv2-W.
