Cisco N9K-PUV-1200W Full English Description

Product Overview

Key Features

1. 1230 Watt Continuous Rated Output

   Delivers maximum 1230W continuous 12VDC main output plus standby power. Supports 1+1 redundant deployment and dynamic load sharing to eliminate single-point power failure risks for mission-critical leaf-spine network environments.
2. Universal Hybrid HVAC / HVDC Input Range

   Compatible with modern data center high-voltage power distribution:

• AC Input: 200 VAC ~ 277 VAC, 47–63 Hz
• HVDC Input: 192 VDC ~ 400 VDC

1. Dual-Directional Auto-Adaptive Airflow

   Automatically synchronizes airflow direction consistent with fan modules inside the chassis, supporting either Port-Side Intake (Reverse Airflow) or Port-Side Exhaust (Forward Airflow).

   Important Note: All fan modules must adopt identical airflow direction. AC, telecom negative -48V DC and HVAC/HVDC hybrid power supplies cannot be mixed within one switch chassis.
2. Hot-Swap FRU Architecture

   Supports online insertion and removal. Technicians can replace defective power modules without shutting down the host switch, enabling non-disruptive live hardware maintenance.
3. Real-Time Telemetry & LED Status Indication

   Front-panel LED indicators display power input status and operational health. The module transmits temperature, voltage and fault alarm metrics to the NX-OS operating system via chassis backplane.
4. Multi-Layer Hardware Protection

   Integrated overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP) and short-circuit protection to safeguard both the power supply and host switch hardware.
5. 80 PLUS Platinum High Energy Efficiency

   High conversion efficiency minimizes power loss and thermal generation, effectively reducing cooling consumption in large-scale sustainable data center deployments.
