C9300X-48TX-A vs C9350-48TX

Both models provide 48 multigigabit copper access ports, but their platform and operating models differ. C9300X-48TX-A uses the established C9300X modular-uplink design with StackWise-1T and Network Advantage; C9350-48TX adds newer C9350 uplink modules, up to 400G uplinks, StackWise-1.6T and Cisco Networking Cloud management/licensing. Compare uplink optics, routing and ACL scale, power supplies and subscription requirements before treating the C9350 as a direct replacement.

Buying decision

How to choose between C9300X-48TX-A and C9350-48TX

Review the differences in this order to identify the model that best fits the intended deployment.

  1. 01

    Ports and uplinks

    Match access media, port count and speed first, then confirm that the uplink design fits the distribution layer.

  2. 02

    PoE and power

    Total the power required by connected devices and verify the PoE standard, budget, power supplies and redundancy.

  3. 03

    Performance and software

    Compare forwarding, stacking and scale in the intended topology, then confirm the license tier and software release.

Before ordering Confirm the exact Product ID, license tier, power supplies, accessories and regional requirements.
