8-Slot NI PXIe-1062Q Backplane Installation Guide
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 a x4 PCI Express link from the system controller slot
to slots 3, 4, and 5, and a x1 PCI Express link to a PCI Express to PCI
Translation Bridge on the backplane. The PCI Express to PCI Translation
Bridge on the backplane provides a 32-bit/33 MHz PCI bus to slots 2, 3, 5,
6, 7, and 8.
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.
The system controller can control the power supply with the PS_ON#
signals. A logic low on this line turns on the power supply.
Hybrid Peripheral Slots
The chassis includes two hybrid peripheral slots as defined by the
PXI-5
PXI Express Hardware Specification
: slot 3 and slot 5. A hybrid peripheral
slot can accept the following peripheral modules:
•
A PXI Express peripheral with a x4 or x1 PCI Express link to the
system slot.
•
A CompactPCI Express Type-2 peripheral with a x4 or x1 PCI Express
link 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 32-bit PCI bus.
•
A CompactPCI 32-bit peripheral on the backplane 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 connects only to PXI Local Bus 6 left and right.
PXI Peripheral Slots
Four PXI peripheral slots accept PXI or CompactPCI peripherals: slot 2,
slot 6, slot 7, and slot 8. These slots are on the backplane 32-bit PCI bus.
These slots offer full PXI functionality, but have no PXI Express features.
The 64-bit PCI signals on the P2 connectors are not connected.
