D1 IPB-RIO CPU Extension

To enhance the I/O and serviceability of their CPUs, Inova have introduced rear I/O modules that connect to a CompactPCI connector on the rear of the Master Slot on the backplane. All standard Inova backplanes are equipped with this R2 connector so that even if the rear I/O functionality is not requested at time of order, it can be implemented at a later stage.

Currently, Inova have 4 rear I/O transition modules in their product range. Three of these are documented here.

D1.1 IPB-RIO-HD-FD

As its name suggests, this transition module recovers the embedded IDE and floppy signals from the CompactPCI backplane and presents them in a form ready for device connection. One of the advantages of this module is its ability to attach an IDE device without direct flex-cable connection to the CPU base board. This facilitates servicing and allows a CPU for example, to be switched without touching the software stored on the HD. Likewise, a hard-disk can be exchanged without having to disassemble the CPU!
