Cisco C9404R-E Full Product Description

1. Short Overview

• Suffix breakdown definition:
  • C9400: Catalyst 9400 modular enterprise aggregation switch series
  • 4: Total 4 chassis slots (2 Supervisor + 2 Line Card)
  • R: Side-to-side airflow, shallow closet-optimized compact chassis
  • -E: Enhanced pre-assembled unit with factory preloaded dual Gen2 UADP 3.0 high-performance supervisors, heavy-duty fan tray and max-capacity PoE AC power supplies
• Core differentiators vs C9404R (bare chassis): All critical high-end FRUs pre-installed at factory, eliminating separate procurement of supervisors, fan tray and power hardware for rapid high-performance fabric deployment.
• Core differentiators vs C9404R-A: C9404R-A uses Gen1 UADP 2.0 supervisors with limited fabric scale; C9404R-E ships with dual C9400X-SUP-2XL UADP 3.0 flagship supervisors for full non-blocking 48 Tbps fabric, larger MAC/routing tables, advanced streaming telemetry and expanded SSD container storage.
• Differentiated from larger C9407R/C9410R by compact 6RU footprint and only two line card slots supporting a maximum of 96 front-panel access ports.
