ALTUS NJ1001 - Single CPU with Redundant Rack Expansion and Loopback

1. INTRODUCTION
1.1.4.5. Single CPU with Redundant Rack Expansion and Loopback
This architecture is based on the use of two bus expansion modules in the racks. With more than one expansion module,
the system has an outstanding availability, because it supports single cable failure or expansion module failure. Just as the
previous architecture, this is intended for systems where maintenance is an issue and the system must be available for a longer
time. In this architecture, the racks must be mounted as the following diagram, where the expansion modules are located side
by side on the last slot positions. Besides, there are unused expansion module ports that must be left unconnected.
