Cisco Nexus® 9400 Series Switches provide high-density 400G solutions in a centralized modular chassis design.

The Cisco Nexus 9400 Series centralized modular switches expand the Cisco Nexus 9000 Series portfolio with a new chassis that supports very high port-density 400 Gigabit expansion modules.

As data centers continue to evolve to support next-generation applications such as machine learning that drive massive growth in intra-data-center traffic bandwidth, data-center operators require compact, high-capacity, and highly efficient switches to upgrade data-center fabrics. They need security, automation, visibility, analytics, and assurance. Equipped to support this next-generation cloud architecture, the Cisco Nexus 9400 series switches are based on Cisco Cloud Scale technology.

The Cisco Nexus 9400 series centralized modular architecture can scale up to 25.6 Tbps with a combination of field-replaceable switch cards, expansion modules, power supplies, and fans.

The Cisco Nexus 9400 Series Switch has a new design with a height of 4 rack units and a depth of 24 inches including 8 expansion slots to support 64 ports of 400G, or 128 ports of 200G, or 176 ports of 10/25/50G, with MACsec capability on all ports.

Furthermore, the chassis architecture supports a supervisor and up to 8 expansion modules, fan tray redundancy with 5 fan trays, and power supply redundancy.

The Cisco Nexus 9400 series supports Precision Time Protocol (PTP) with Class C timing accuracy for telecom as well as media profiles. Through PTP and synchronous Ethernet, it delivers frequency and time distribution with high accuracy.

Cisco provides two modes of operation for Cisco Nexus 9000 Series Switches. Organizations can deploy Cisco® Application Centric Infrastructure (Cisco ACI®) or Cisco NX-OS mode.
