Cisco N2200-PAC-400W-B Full English Description

The Cisco N2200-PAC-400W-B is a hot-swappable 400W AC Field-Replaceable Unit (FRU) power supply module designed for Cisco Nexus 2000 Series Fabric Extenders (FEX) and selected Nexus 3000 fixed data center switches. It adoptsPort-Side Intake (Reverse Airflow / Front-to-Back Airflow)identified by burgundy handle marking. This AC power module provides stable 12VDC power output for low-latency access layer fabric architecture, widely deployed within enterprise data centers and colocation facilities equipped with standard alternating current power distribution.

400 Watt Continuous Rated Output

Delivers maximum 400W continuous 12VDC power output. Supports 1+1 redundant power deployment and dynamic load sharing to eliminate single-point power failure risks for access-layer network infrastructure.
Universal Wide-Range AC Input

Globally compatible mains power specification:

Input Voltage: 90 VAC ~ 264 VAC
Frequency: 50–60 Hz

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 modules installed within one chassis must maintain identical airflow direction. Do NOT mix PI (port-side intake, N2200-PAC-400W-B) and PE (port-side exhaust, N2200-PAC-400W) modules. AC and DC power supplies cannot be mixed inside the same chassis.
Hot-Swap FRU Architecture

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

Built-in OK and FAIL status LEDs display operational status. The module transmits temperature, voltage and fault alarm metrics to the host device for remote monitoring.
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 hardware.
Optimized Energy Efficiency

High power conversion efficiency reduces thermal generation and lowers rack cooling consumption for access layer deployments.
