The PACSystems* RX3i Universal Backplanes provide a dual-bus backplane that supports PCI-based

(IC695) and serial (IC693 and IC694) I/O and option modules. The RX3i Universal Backplanes also

support Series 90-30 IO and option modules.  See the PACSystems RX3i System Manual, GFK-2314 for

lists of supported modules. The 16-slot Universal Backplane (IC695CHS016), and the 12-slot Universal

Backplane (IC695CHS012) include the following features:

▪ Terminal Strip on the left end for Isolated +24V input

▪ Backplane grounding point

▪ An integral grounding bar for connecting module/shield grounds

▪ Serial Expansion connector for connection to Serial Expansion and Remote Backplanes

▪ Slot numbers printed on the backplane that can be used as a reference for configuration.

The 12-slot Universal Backplane (IC695CHS012) is illustrated below.

Backplane Orientation

Backplanes must be mounted horizontally to meet product

performance and reliability specifications by providing

adequate airflow around the modules.  Other mounting

orientations may affect system performance and/or reliability

and are therefore not recommended.
