Cisco NXA-PHV-2KW-PI Full English Description

Product Overview

Key Features

1. 2000 Watt Continuous Rated Output

   Delivers maximum 2000W continuous 12VDC main output with 36W standby power support. Supports 1+1 redundant configuration and dynamic load sharing to eliminate single-point power failure risks for mission-critical data center networks.
2. Hybrid HVAC / HVDC Universal Input Range

   Dual-input design compatible with contemporary data center power infrastructure:

• AC Input: 200 VAC ~ 277 VAC, 50–60 Hz
• HVDC Input: 240 VDC ~ 380 VDC

1. Port-Side Intake (Reverse Airflow)

   Cool air enters the chassis from port side, hot air exhausts toward fabric side.

   Important Note: All power supplies and fan trays deployed within one chassis must maintain identical airflow direction. Do NOT mix PI (port-side intake) and PE (port-side exhaust) modules. Standard AC, telecom negative -48V DC and PHV hybrid power supplies cannot be mixed in the same switch chassis.
2. Hot-Swap FRU Architecture

   Supports online insertion and removal. Engineers can replace faulty power modules without shutting down the host switch, enabling non-disruptive in-service 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 data 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. High Power Conversion Efficiency

   Maintains ≥90% energy efficiency between 20% and 100% operating load, minimizing power loss and thermal generation to reduce cooling consumption in large-scale data center environments.
