Cisco NC55-900W-DCFW-HD= 900 W DC PSU | NCS 5500, Front-to-Back — NC55-900W-DCFW-HD=

Keep Cisco NCS 5500 deployments aligned with a 900 W DC power supply engineered for port-side intake and front-to-back airflow. In routing environments, power and thermal design are inseparable: the wrong airflow path can complicate rack planning, while the wrong PSU can limit serviceability. This module is built for teams that already know the cost of getting either wrong. The 900 W output supports the power profile of NCS 5500 systems while preserving the airflow direction required by the chassis. That matters in dense network rows where cooling strategy is standardized and every component must match the rack’s thermal model. For operations teams, this PSU helps keep replacement simple and predictable, especially when maintaining spares for field service or scheduled maintenance. Compared with generic replacement parts, a platform-matched Cisco PSU reduces compatibility risk and helps protect uptime in critical routing paths. It is the kind of component that earns its place in a production network by fitting the system exactly as intended.
