The chassis provides seven (7) hybrid peripheral slots as defined by the PXI-5 PXI Express Hardware Specification: slots 2, 3, 4, 5, 7, 8, and 9. A hybrid peripheral slot can accept the following peripheral modules:

• A PXI Express peripheral with x8, x4, or x1 PCI Express link through a switch to the system 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 through a PCI Express switch to the system slot.
• A hybrid-compatible PXI Peripheral module modified by replacing the J2 connector with an XJ4 connector installed in the upper eight rows of J2. Refer to the PXI Express Specification 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 functionality except for PXI Local Bus. The hybrid peripheral slot only connects to PXI Local Bus 6 left and right.
