Cisco PWR-C4-950WAC-R Power Supply - 950W AC Refurbished

The Cisco PWR-C4-950WAC-R is a high-performance, hot-swappable AC power supply designed specifically for the Cisco Catalyst 4500-X Series switches. This module provides 950W of power, ensuring the switch has a reliable and efficient energy source for high-density networking environments. The "R" in the part number signifies Back-to-Front airflow (Port-Side Intake), which is a critical specification for data centers that utilize specific hot/cold aisle cooling configurations.

This power supply is engineered for high availability, supporting N+1 redundancy when a second power supply is installed in the chassis. It is highly efficient and features a self-cooling mechanism with internal fans. As a front-end plug-in module, it can be replaced or added while the switch is operational, minimizing potential downtime for enterprise-class networks.
