Core Product Positioning
The Cisco N9K-PDC-3000W is a high-capacity hot-swappable -48V DC power supply module engineered exclusively for Cisco Nexus 9500 modular spine switch chassis. Designed for carrier-grade DC power infrastructure widely adopted in data centers, colocation facilities and telecom central offices, this unit delivers stable, high-efficiency power to supervisors, fabric modules, high-density 10G/25G/40G/100G line cards and internal cooling subsystems. It supports flexible N+1 and N+N redundant power architectures to guarantee non-stop operation for mission-critical leaf-spine and ACI fabric deployments.
