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 Peripheral 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.
