Cisco PWR-4330-AC Full English Description

Product Overview

Key Features

1. 350 Watt Continuous Rated Output
   Provides sufficient power for standard ISR4331 configurations with basic NIM modules.

Important Note: This modeldoes NOT support PoE. Deployments requiring IEEE 802.3af/at PoE must selectPWR-4330-POE-AC (530W PoE-capable).

1. Universal Wide-Range Global AC Input
   Worldwide auto-ranging AC specification:

• Input Voltage: 100 VAC ~ 240 VAC
• Operating Frequency: 50 Hz – 60 Hz
• Standard built-in IEC C14 power inlet

1. Internal Hot-Pluggable Modular Design

   Installs inside the ISR4331 router chassis.

   Important Note: Supports dual redundant power supply installation. Do not mix non-PoE (PWR-4330-AC) and PoE PSU (PWR-4330-POE-AC) in the same chassis. Not compatible with ISR4321, ISR4351 or other ISR4000 models.
2. Hot-Swap Support

   Supports Online Insertion and Removal. Engineers can replace defective power modules without powering off the router, enabling non-disruptive hardware maintenance and minimizing business service interruption.
3. LED Status Indicators & IOS-XE Telemetry

   Front faceplate status LEDs display input power status and operational health. The module continuously reports voltage, internal temperature and fault events to IOS-XE for remote monitoring and alarm notifications.
4. Multi-Layer Hardware Protection

   Integrated overvoltage protection (OVP), overcurrent protection (OCP), overtemperature protection (OTP), surge protection and short-circuit protection to protect both the power supply and ISR4331 router hardware.
5. High Energy Efficiency

   Optimized power conversion architecture reduces heat generation and idle power draw, supporting stable 24/7 continuous rack operation for enterprise branch networks.
