The Cisco C9400-SUP-1XL-Y is a next-generation supervisor engine for the Catalyst 9400 Series Switches, optimized for enterprise-class core and aggregation layers. It supports up to 240 Gbps per slot in a 4-slot chassis and offers unique investment protection with a 25G uplink connectivity option. The '-Y' variant enables up to 90 W per port when paired with Cisco UPOE+ line-cards, making it ideal for high-power PoE deployments like IP cameras, Wi-Fi 6 APs, and LED lighting. It is built on Cisco's programmable UADP 2.0 ASIC, delivers wire-rate MACsec-256 on every access port, and supports flexible SDM templates and on-box analytics with optional NVMe SSD. Uplink options are software-selectable: 8x 10G SFP+ or 2x 40G QSFP+. It is designed for scalability, high availability (NSF/SSO, ISSU), and security in modern campus and aggregation networks.
