By plugging a PXI MXI-3 module into any of slots 2 through 8 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 primary or secondary. In accordance with the PCI-to-PCI
Bridge specification, up to 254 chassis can be linked to a single
desktop PC.
