National Instruments PXI Slot Blocker
The PXI Slot Blocker (Part Number: 199198-01 (5 included in Kit)) is specially designed to occupy and provide a protective cover to empty slots in controllers and chassis to keep up system quality and performance. The PXI Slot Blocker is compatible with PXI chassis and control parts, serving an important functional purpose of enhancing performance by increasing the total system cooling. Airflow within the PXI chassis is redirected away from empty slots and towards slots occupied by PXI modules.
To enhance the cooling performance of specific PXI chassis, NI suggests use PXI Slot Blockers in conjunction with either standard or EMC filler panels. These blockers as highly recommended for PXI chassis where the chassis fan location is located in the rear. These include the PXI-104x and PXIe-106x series, the PXIe-108x series (except for the PXIe-1083 and PXIe-1088), the PXIe-109x series (except for the PXIe-1090) and the PXIe-1075. It is also recommended for PXI chassis that have the chassis fan located below the card cage. These include the PXI-103x series, the PXIe-107x series (except for the PXIe-1075), the PXIe-1083, PXIe-1088, and PXIe-1090. The PXI Slot Blocker is not recommended for use with NI PXI chassis options in which the chassis is a dual-stacked configuration.
The following things are needed in order to effectively use the PXI Slot Blocker: a compatible PXI or PXI Express chassis, a system controller that corresponds to the PXI and PXI Express chassis, peripheral modules for the PXI or PXI Express chassis, and PXI Filler Panels (sold separately). To use the PXI Slot Blockers, insert one into all of the empty slots of the PXI(e) chassis. A PXI Filler Panel should then be installed over the blocked slots in order to ensure adequate cooling for all of the modules.
The PXI Slot Blocker leverages its engineered compatibility with the PXI and PXI Express configurations to improve reliability and life span of the PXI system by improving the system’s ability to actively cool itself. While in use, the PXI Slot Blocker moves air away from open slots to filled slots. The PXI Slot Blocker should be used in applications in which enhanced cooling is required.
