The system timing slot has a pin (PXI_CLK10_IN) through which a system timing module
may source a 10 MHz clock to which the backplane phase-locks.

Expansion Slot
Peripheral Expansion Slot
A peripheral expansion slot is located in slot 10 and can be identified by its black connectors
and card guides. The peripheral expansion slot allows for a multiple-slot wide module (that
expands to the right) to expand into the peripheral expansion slot to avoid covering peripheral
slots.
The peripheral expansion slot provides power and connectors for alignment, but does not
provide I/O. For more information about peripheral expansion slot connector pinouts, refer to
the
Expansion Slot Pinouts
section. The peripheral expansion slot will accept the following
peripheral modules:
•
Multiple-slot PXI Express peripheral modules that expand to the right. The module's
main connectors for signaling are mated in a peripheral slot to the left and a secondary
connector for power and/or mechanical alignment may be mated.
Note
The peripheral expansion slot does not provide PCI/PXI Express or timing
signals. A single-slot module installed in the peripheral expansion slot will not be
functional.
Note
For connector pinouts for the chassis backplane, refer to the
PXI-5 PXI
Express Hardware Specification
, Revision 2.0.
