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
Inhibit Mode Switch section for details about the Inhibit Mode switch.
Hybrid Peripheral Slots
The chassis provides 16 hybrid peripheral slots as defined by the
PXI-5 PXI Express Hardware
Specification
: slots 2 to 9 and slots 11 to 18. 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-2 x8 PCI Express,
providing a maximum nominal single-direction bandwidth of 4 GB/s.
•
A CompactPCI Express Type-2 Peripheral with x8, x4, or x1 PCI Express link through a
PCI Express switch 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’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.
