Cisco switch comparison
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.
