slot. One PCI Express switch also has a x1 PCI Express link routed to a
PCI Express-to-PCI bridge that provides a 32-bit, 33 MHz PCI bus to the
four hybrid slots. Refer to Figure 2 for the connectivity of PCI Express
and PCI.
By default, the system controller controls the power supply with the
PS_ON# signals. A logic low on this line turns on the power supply.
Hybrid Peripheral Slots
The backplane includes four hybrid peripheral slots as defined by the
PXI-5
PXI Express Hardware Specification
: slots 5 to 8. 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 or through a switch to the system slot.
•
A CompactPCI Express Type-2 peripheral with a x4 or x1 PCI Express
link to the system slot or through a 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 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 Express Peripheral Slots
There are two PXI Express peripheral slots: slots 2 and 3. PXI Express
peripheral slots can accept the following modules:
•
A PXI Express peripheral with a x4 or x1 PCI Express link to the
system slot or through a switch to the system slot.
•
A CompactPCI Express Type-2 peripheral with a x4 or x1 PCI Express
link to the system slot or through a switch to the system slot.
System Timing Slot
The system timing slot is slot 4. The system timing slot accepts the
following peripheral modules:
•
A PXI Express system timing module with a x4 or x1 PCI Express link
to the system slot through a PCI Express switch.
•
A PXI Express peripheral with a x4 or x1 PCI Express link to the
system slot through a PCI Express switch.
•
A CompactPCI Express Type-2 peripheral with a x4 or x1 PCI Express
link to the system slot through a PCI Express switch.
