MXI-3 Chassis Expansion
By plugging a PXI MXI-3 module into any slot other than Slot 1 of a
PXI/CompactPCI chassis and a PXI MXI-3 module into Slot 1 of an
additional PXI/CompactPCI chassis and connecting them with a cable,
one PXI/CompactPCI chassis can be expanded to two. The PXI MXI-3
modules detect the slot in which they reside and automatically configure
themselves as the primary or secondary bus interface.
Figure 3-2 shows the most basic MXI-3 configurations and Figure 3-3
shows other possible configurations.
