Cisco NXA-PHV-1100W-PI Full English Description

Product Overview

Key Features

1. 1100 Watt Continuous Rated Output

   Delivers maximum 1100W continuous 12VDC power output with dedicated standby power. Supports 1+1 redundant deployment and dynamic load sharing to eliminate single-point power failure risks for mission-critical network environments.
2. Hybrid HVAC / HVDC Wide Input Compatibility

   Universal dual-input design for modern sustainable data center power infrastructure:

• AC Input: 100 VAC ~ 277 VAC, 47–63 Hz
• HVDC Input: 240 VDC ~ 380 VDC

1. Port-Side Intake (Reverse Airflow)

   Cool air enters the switch from port side, and hot air exhausts from fabric side.

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

   Supports online insertion and removal. Technicians can replace faulty power modules without shutting down the host switch, enabling non-disruptive 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 protect 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 lowering cooling expenditure for large-scale data center deployments.
