NI PXIe-1082 Backplane Architecture
System Controller Slot
The system controller slot is Slot 1 of the chassis and is a 4-Link
configuration system slot as defined by the CompactPCI Express and
PXI Express specifications. It has three system controller expansion slots
for system controller modules that are wider than one slot. These slots
allow the system controller to expand to the left to prevent the system
controller from using peripheral slots.
The backplane routes the first x4 PCI Express link from the system slot
directly to slot 2. The other three x4 PCI Express links each are routed
from the system slot to a PCI Express switch. The three PCI Express
switches have x4 PCI Express links routed to each remaining peripheral
