C1.12 ITM-RIO(C&D)-FHLU Extension
To further enhance the I/O and serviceability of their CPUs, Inova have introduced a rear I/O
module (figure C1.12) that connects 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.
One of the advantages of this module (apart from its obvious size benefit) is its ability to attach a
3.5” IDE device (or Inova IPM-ATA Mass Storage Device) without direct connection to the CPU
base board. This facilitates servicing and allows a CPU for example, to be exchanged without
touching the software stored on the HD. Likewise, a hard-disk can be swapped without having to
disassemble the CPU! Two slim-line (notebook) floppy interfaces are implemented allowing the
module to be compatible with existing Inova PIII CPUs (with RIO(C)) as well as the P4, PM and CM
family.
The integration of USB (1.1) with both the standard connector and notebook style internal con-
nector facilitates the integration of commercially available FDs or similar devices. The signal de-
scription of the standard connector can be obtained by referring to page C - 11
