Author : Globalzhitui lyy | Published On : 24 Apr 2026

The Cisco Catalyst C9404R-E serves as the foundational 4-slot chassis for the premier Catalyst 9400 Series modular switching platform. Engineered to bring intent-based networking to the enterprise campus access and aggregation layers, this highly resilient chassis is designed for space-constrained environments that still require the ultimate reliability of a modular architecture.

Unlike fixed-configuration switches, the C9404R-E protects your infrastructure investment for up to a decade. By allowing IT administrators to seamlessly upgrade Supervisor engines, add advanced multi-gigabit line cards, and expand PoE capabilities without ever ripping and replacing the core chassis, it dramatically lowers Total Cost of Ownership (TCO). This "-E" model includes the foundational Cisco IOS XE Network Essentials software license.
