The GE-Emerson IC698CHS117 Rx7i 17-Slot Front Mount Rack applies backplane connectors that are spaced on 0.8in centers to accommodate single-width Rx7i modules, VME modules, and single-width Series 90-70 modules. Double-width Series 90-70 modules use two slots each.
The rack accepts a power supply in slot 0 and a CPU in slot 1. The Rx7i CPUs with Ethernet daughter card are double-width modules and use slots 1 and 2. The remaining slots can be used for one of the following I/O combinations:
- Fifteen single-width modules (with no double-width modules installed)
- Eight double-width modules
- A combination of double-width and single-width modules
Integration of VME modules must be in accordance with guidelines that are described in the Rx7i User's Guide to Integration of VME Modules, GFK-2235 (see Documents).
The Rx7i 17-Slot Front Mount Rack is considered open equipment, and must be installed in a protective enclosure rated IP54 or greater.
