Hybrid Peripheral Slots
The chassis provides five (5) hybrid peripheral slots as defined by the
PXI-5 PXI Express
Hardware Specification
: slots 7, 8, 9, 11, and 12. 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
switch to the system slot.
•
A hybrid-compatible PXI Peripheral module that has been 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.
PXI Express Peripheral Slots
There are eleven (11) PXI Express peripheral slots: slots 2 to 6 and 13 to 18. PXI Express
peripheral slots can accept the following peripheral modules:
•
A PXI Express peripheral with x8, x4, or x1 PCI Express link to the system slot through a
PCIe switch. 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 the system
slot through a PCIe switch.
