The NI 1/2-Slot Blank Filler Panel (3U) is a passive rackmount component designed to fill unoccupied half-slot positions within 3U PXI and CompactPCI chassis. By occupying empty slots, this filler panel optimizes system airflow, prevents dust and contaminant ingress, and maintains structural integrity of the chassis assembly.
– Technical Specifications
• Form Factor: 3U module size
• Slot Width: Half-slot configuration
• Material: Metal construction for durability and shielding
• Mounting: Captive mounting screws or thumbscrews
• Mechanical Interface: Compatible with standard 3U chassis slot architecture
– Key Features
• Fills empty half-slot positions to eliminate thermal bypass paths
• Enhances cooling performance by directing airflow through active modules
• Prevents dust accumulation in unused chassis cavities
• Maintains professional aesthetic appearance of rackmount systems
• Supports deployment alongside slot blockers for optimized thermal management
• Contributes to overall mechanical stability through complete slot occupation
– Typical Applications
• PXI modular instrument systems requiring thermal optimization
• CompactPCI chassis configurations with partially populated slots
• Cooling-critical measurement and test applications
• Systems requiring improved dust protection in laboratory or industrial environments
– Compatibility & Integration
This filler panel integrates with various 3U PXI and CompactPCI chassis from National Instruments. It complements single-slot and double-slot filler panels for comprehensive rack space management. When installed in conjunction with the chassis cooling system, it ensures proper thermal distribution across active measurement modules by preventing recirculation of exhaust air through unoccupied spaces.
