Introduction

Cisco Catalyst® 9400 Series switches are Cisco's lead 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 that is 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 table stakes across the portfolio. Cisco Catalyst 9400 Series switches deliver state-of-the-art High Availability (HA) with capabilities like SSO/NSF, uplink resiliency, 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 is closet-friendly with ~16 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.
