Keep power delivery aligned with the airflow strategy of dense Cisco storage systems. The DS-CAC-1400W-I provides 1,400 W of AC output in a port-side intake configuration, helping maintain proper cooling direction in racks where front-to-back or side-specific airflow is part of the platform design. That matters when you are supporting sustained I/O, expansion growth, and long duty cycles under real production load. This power supply is built for environments where downtime is expensive and maintenance windows are short. Hot-swap serviceability supports replacement without unnecessary disruption, while the high-wattage design gives the platform the headroom needed for demanding configurations. For infrastructure teams standardizing on Cisco hardware, the right PSU is not just a spare part — it is part of the thermal and availability model that keeps the system stable. Choose this module when you need a replacement or spare that matches the original airflow and power profile of the chassis. It is the practical option for preserving system integrity, avoiding mismatched cooling paths, and keeping enterprise storage online with minimal intervention.
