Slot Blockers
Optional slot blocker kits are available from National Instruments for
improved thermal performance when all slots are not used.
NI PXIe-1065 Chassis Backplane Overview
This section provides an overview of the backplane features for the
NI PXIe-1065 chassis.
Interoperability with CompactPCI
The design of the NI PXIe-1065 provides you the flexibility to use the
following devices in a single PXI Express chassis:
•
PXI Express compatible products
•
CompactPCI Express compatible 4-Link system controller products
•
CompactPCI Express compatible Type-2 peripheral products
•
PXI peripheral products
•
Standard CompactPCI peripheral products
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 7 and 8, 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/33MHz PCI bus to slots 2 to 7.
The second PCI Translation Bridge provides PCI bus to slots 11, 12, 13, 15,
16, 17, and 18 (not to slot 14).
A x4 link goes to the PXI Express switch and the PCI Express connectivity
of slots 9 to 14 is connected through the switch.
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.
