Cisco Nexus 1500W PSU Port-Side Intake | Nexus Power Supply — NXA-PAC-1500W-PI=

Keep critical switching infrastructure aligned with the airflow and power profile the chassis expects. The Cisco Nexus 1,500 W PSU with port-side intake is designed for environments where thermal direction is part of the deployment standard, not an afterthought. That matters in dense racks, mixed-airflow rows, and production networks where a mismatched power supply can complicate cooling design or slow recovery. This PSU is a practical fit for teams that maintain spare inventories for fast replacement and predictable serviceability. It supports the kind of operational discipline that reduces downtime risk: matching the correct intake orientation, preserving rack airflow patterns, and keeping the switch ready for sustained load. For infrastructure teams, that precision is worth more than a generic replacement part. Use it to keep Nexus platforms running within the intended thermal envelope and to simplify lifecycle support across standardized Cisco environments. When uptime, airflow, and compatibility all need to line up, this PSU helps keep the rack stable and the network online.
