Overview

The Panduit Net-Direct Air Inlet Duct (SKU: CNLTD21B2) is engineered to optimize airflow for Cisco Catalyst 4900M switches, ensuring enhanced thermal management and operational efficiency. This 2RU black duct directs cold airflow directly into the switch intakes, accommodating both in-line and side air sources. A key benefit of the CNLTD21B2 is its passive operation; it requires no external power to function. By facilitating direct cold air delivery, it significantly reduces the workload on the switch's internal fans, leading to a potential reduction in fan power consumption by up to 250W. This substantial energy saving directly translates into improved overall energy efficiency and increased reliability for your network infrastructure, ultimately driving cost savings. The duct is designed for a 2RU rack space and comes as a 2-piece set, explicitly excluding blanking panels. This product is manufactured in the US and adheres to UNSPSC code 43223301. It is compatible with Cisco Catalyst 4900M switches, providing a crucial component for effective cooling strategies in data centers and network closets. The Net-Direct Air Inlet Duct is part of a broader system that enables effective deployment of network switches within Net-Contain3 Cold Aisle Containment deployments, allowing for reduced fan power energy consumption by enabling lower fan speeds, thereby improving switch reliability. While specific dimensions for this model are not detailed in the provided catalog excerpt, similar Panduit air inlet ducts are designed with precise fitment in mind for various switch depths and rack configurations.
