Cisco® Catalyst® 9400 Series switches are Cisco’s lead modular enterprise access switching platform and as part of the Catalyst 9000 family, are built to transform your network to handle a hybrid world where the workplace is anywhere, endpoints could be anything, and applications are hosted all over the place.

The Catalyst 9400 Series, including the new Catalyst 9400 SUP-2/2XL supervisor and line cards, continues to shape the future with continued innovation that helps you reimagine connections, reinforce security and redefine the experience for your hybrid workforce big and small. These switches form the foundational building blocks for Cisco SD-Access, our leading enterprise architecture. The platform provides strong investment protection, with a chassis architecture that is capable of supporting up to nine Tbps of system bandwidth and industry-leading power delivery with high-density IEEE 802.3bt PoE (60W and 90W). Redundancy is now available across the portfolio. Cisco Catalyst 9400 Series switches deliver state-of-the-art high availability with capabilities such as Nonstop Forwarding and Stateful Switchover (NSF/SSO), In-Service Software Upgrade (ISSU), uplink resiliency, and N+1/N+N redundancy for power supplies and Cisco StackWise® Virtual (SVL) redundancy with ISSU. The platform is enterprise-optimized with an innovative, dual‑serviceable fan-tray design and side-to-side airflow and is closet-friendly with approximately 16 inches in depth. A single system can scale up to 480G per slot with SUP-2XL, 384 access ports with your choice of 10G, 5G and 2.5G mGig copper, 1G copper, Cisco UPOE®+, Cisco UPOE and PoE+ options and up to 384 ports of 10G Fiber and 1G Fiber options. The platform also supports 100G/40G/25G/10G uplink options and advanced routing and infrastructure services, SD-Access capabilities, and network system virtualization. These features enable placement of the platform in the core and aggregation layers of small- to medium-sized campus environments.
