PXIe-1066DC Chassis Backplane Overview
This section provides an overview of the backplane features for the PXIe-1066DC chassis.
Interoperability with CompactPCI
The design of the PXIe-1066DC 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.
By default, the system controller will control the power supply with the PS_ON# signal. A logic
low on this line will turn the power supply on.
Note
The Inhibit Mode switch on the rear of the chassis must be in the
Default
position for the system controller to have control of the power supply. Refer to the
section of Chapter 2,
Installation and Configuration
, for details
about the Inhibit Mode switch.
