Two new switching series

High-bandwidth innovation is here. The Nexus 9000 Series welcomes two new 400G-ready modular systems.

What is 400G?

As data-hungry application capacity demands outpace current high-speed transport abilities, 400 Gigabit Ethernet is a promising and evolving technology that supports an immediate need in fiber optics. All with comparatively low operational expenses (OpEx) and a smaller footprint.

When built for the most demanding environments, 400G delivers high flexibility, customer choice, and a foundation for the cloud networking frontier.

High-density meets high expectations 

Power efficiency

Build a network optimized for speed, simplicity, and scale from data center to the cloud.


Kick-start your sustainability journey with an architecture that's designed with your net- zero goals in mind.

Simplified operations

It's easier than ever to deploy, manage, and operate your 400G Nexus networks.
