APC NetShelter SX 48U Duct Kit AR7747 | Rack Cooling, Cisco Nexus

Protect switch performance in dense rack rows by shaping airflow where standard rack cooling falls short. The APC NetShelter SX 48U Duct Kit for Cisco Nexus 7018 is designed to support air distribution in power-dense racks and low-pressure areas, helping maintain more predictable thermal behavior around the chassis. Built for the Cisco Nexus 7018 switch chassis, this accessory kit includes side airflow ducts, side baffles, foam gasket strips, baying hardware, and mounting hardware to help close gaps that can undermine containment. In practical terms, it helps reduce hot-air recirculation and improves the consistency of front-to-back cooling paths in environments where every degree matters. For infrastructure teams standardizing on NetShelter SX enclosures, this kit adds a purpose-built layer of airflow control without changing the rack architecture. It is a focused answer for deployments where switch density, thermal stability, and serviceability all have to coexist. Backed by a 2-year limited warranty, it fits the kind of investment protection expected in enterprise network rooms and data center rows.
