The backplane connects the system slot to a PCI Express switch using a Gen-3 x8 and a Gen-3x16 PCI Express link. The PCIe switch is divided into 2 logical PCIe switches to distributePCIe connections to the peripheral slots and to 2 PCIe-to-PCI bridges to provide PCI busses tothe hybrid peripheral slots.System slot link 1 is a Gen-3 x8 PCI Express link to the primary PCI Express switch,providing a nominal bandwidth of 8 GB/s (single direction) between the system controller andlogical PCI Express switch 1. PXI Express peripheral slots 2-4 are connected to logical PCIExpress switch 1 with Gen-3 x8 PCI Express links and are downstream of system slot link 1.System slot link 2 is a Gen-3 x16 PCI Express link to the primary PCI Express switch,providing a nominal bandwidth of 16 GB/s (single direction) between the system controllerslot and logical PCI Express switch 2. PXI Express peripheral slots 5-9 are connected tological PCI Express switch 2 with Gen-3 x8 PCI Express links and are downstream of systemslot link 2.The PCI Express-to-PCI bridges are connected to logical PCI Express switch 2 and provide a32-bit, 33 MHz PCI bus for hybrid peripheral slots 2, 3, 4, 5, 7, 8, and 9.The system controller slot also has connectivity to some PXI features such as: PXI_CLK10,PXI Star, PXI Trigger Bus, and PXI Local Bus 6. By default, the system controller controls thepower supply with the PS_ON# signals. A logic low on this line powers on the power supply.Note The chassis Inhibit Mode must be set to Default mode for the systemcontroller to control the power supply.Hybrid Peripheral SlotsThe chassis provides seven (7) hybrid peripheral slots as defined by the PXI-5 PXI ExpressHardware Specification: slots 2, 3, 4, 5, 7, 8, and 9. A hybrid peripheral slot can accept thefollowing peripheral modules:• A PXI Express peripheral with x8, x4, or x1 PCI Express link through a switch to thesystem slot. Each PXI Express peripheral slot can link up to a Gen-3 x8 PCI Express,providing a maximum nominal single-direction bandwidth of 8 GB/s.• A CompactPCI Express Type-2 Peripheral with x8, x4, or x1 PCI Express link to thesystem slot or through a PCI Express switch to the system slot.• A hybrid-compatible PXI Peripheral module modified by replacing the J2 connector withan XJ4 connector installed in the upper eight rows of J2. Refer to the PXI ExpressSpecification for details. The PXI peripheral communicates through the backplane’s 32-bit PCI bus.• A CompactPCI 32-bit peripheral on the backplane’s 32-bit PCI bus.The hybrid peripheral slots provide full PXI Express functionality and 32-bit PXI functionalityexcept for PXI Local Bus. The hybrid peripheral slot only connects to PXI Local Bus 6 leftand right.PXIe-1092 User Guide | © National Instruments | 7
