Cisco Catalyst 9400 Series switches are Cisco’s leading modular enterprise switching access and aggregation platform built for security, IoT, and cloud. This switch series forms the foundational building blocks for SD-Access, Cisco’s leading enterprise architecture. Catalyst 9400 Series switches provide unparalleled investment protection with a chassis architecture capable of supporting up to 9 Tbps of system bandwidth and unmatched power delivery for high-density IEEE 802.3bt (60W and 90W PoE). Redundancy is now essential across the portfolio. Cisco Catalyst 9400 Series switches deliver state-of-the-art high availability (HA) with capabilities like SSO/NSF, uplink resiliency, and N+1/N+N redundancy for power supplies. Catalyst 9400 Series switches are enterprise optimized with an innovative dual-serviceable fan tray design, side-to-side airflow, and are closet-friendly with approximately 16 inches in depth. A single system can scale up to 384 access ports with your choice of 1G copper, 1G fiber, Cisco UPOE+, Cisco UPOE, and PoE+ options, and up to 192 ports of 10G fiber and multigigabit options. The platform also supports advanced routing and infrastructure services, SD-Access capabilities, and network system virtualization. These features enable optional placement of the platform in the core and aggregation layers of small to medium-sized campus environments.
