The minimum requirement for Hot standy system is to have One power supply, one CPU and RIO head 140CRP93200/140CRP93100.
We can configure the Quantum Hot standby system in Unity Pro Software without RIO head. When downloaded the CPU would become
primary but the other CPU would be in offline state. So Quantum Hot standy system would never establish.
However we can configure Quantum Hot standby system without RIO adapter 140CRA93100/140CRA93200 while using Unity Pro V5.0 onwards.
