Getting Started
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/33MHz 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.
By default, the system controller will control the power supply with the
PS_ON# signals. 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
Installation and Configuration
, for details about the Inhibit
Mode switch.
Hybrid Peripheral Slots
The chassis provides 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 x4 or x1 PCI Express link to the system
slot
•
A CompactPCI Express Type-2 Peripheral with x4 or x1 PCI Express
link 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.
