Which one to choose?

Choose Catalyst 9400 if

  • You need a modular switch with PoE/PoE+/UPOE for access or distribution layer.
  • You require high port density, line card flexibility, or future expansion.
  • Your design demands redundant supervisor engines and full high availability.

Choose Catalyst 9500 if

  • You need a compact, high-performance fixed switch for core or aggregation roles.
  • You want high throughput (up to 100G) in a non-modular, easy-to-deploy form.
  • PoE is not needed, but Layer 3 speed and SD-Access compatibility is crucial.
