Cisco Front-to-Back Airflow 1100W Power Supply

The Cisco NXA-PAC-1100W= is a power supply module built for Cisco Nexus 5596T switches that delivers up to 1100 watts of steady output. The unit accepts AC inputs from 100 to 240 volts at either 50 or 60 hertz, so it integrates smoothly into power circuits used in data centers worldwide.

Cooling follows a front to back airflow pattern that mirrors the switch chassis. By drawing cool air through the front and pushing warm air toward the hot aisle, the module helps maintain consistent internal temperatures even in high density racks.

Technicians can install two of these supplies in the same switch for redundancy. If one source fails, the other keeps the system running, and because the module is hot-plug capable, a replacement can be inserted without interrupting traffic.

This RoHS compliant supply is a practical choice when you are upgrading switch capacity, stocking critical spares, or building a new deployment that demands reliable power delivery. Its mix of high output, global input compatibility, and Cisco build quality suits enterprise networks, cloud facilities, and service provider points of presence.
