The Dell R740 Riser 2 & 3 Blank (Part Number: 4D2N2) is a metal filler designed to occupy the PCIe riser slots 2 and 3 in the PowerEdge R740 chassis. By filling these unused slots, it helps maintain proper airflow within the server, ensuring that cooling is directed to active components and preventing thermal inefficiencies that could arise from open spaces.
In addition to its thermal management role, the 4D2N2 blank contributes to the structural integrity and aesthetic uniformity of the server. It protects internal components from dust and physical disturbances, ensuring that the system remains secure and clean even when not fully populated with expansion cards. This blank is an essential component for maintaining the optimal performance and longevity of the PowerEdge R740 server.
