Cisco C9300X-48TX-E — Catalyst 9300X 48-Port 10G Multigigabit Data-Only Switch with Network Essentials
What it is
C9300X-48TX-E is a Cisco Catalyst 9300X Series enterprise access switch designed for high-performance campus and branch networks that need multigigabit copper connectivity up to 10Gbps but do not require PoE.
It provides 48 × multigigabit RJ-45 ports supporting 100M / 1G / 2.5G / 5G / 10G, plus a modular uplink slot for high-speed network modules. The “-E” version includes the Network Essentials software tier.
Why buyers pick C9300X-48TX-E (plain English)
48 ports up to 10Gbps: Every access port supports multigigabit speeds, making it ideal for high-performance workstations, servers, storage devices, and other copper-connected endpoints.
No PoE means lower complexity: This is a data-only model, so it is a strong choice when connected devices have their own power and PoE is unnecessary.
Flexible uplinks: The modular uplink slot lets you select the network module that matches your backbone requirements rather than being locked into fixed uplinks.
1 Tbps stacking: Cisco StackWise-1T provides very high stack bandwidth and allows multiple switches to operate as a single logical system.
Network Essentials licensing: Gives you the core enterprise switching and routing features needed for many campus access deployments without paying for the more advanced Network Advantage feature set.

Where it fits (and when to choose something else)
Perfect for:
- High-performance enterprise access
- 10GbE desktop/workstation connectivity
- Servers connected over copper
- Engineering and media environments
- Networks needing 2.5G / 5G / 10G access
- Customers wanting very high stack bandwidth without PoE
Choose something else if:
- You need UPOE+ / up to 90W PoE → choose C9300X-48HX-E
- You need more advanced routing features → choose C9300X-48TX-A
- You only need 1G access ports → a standard C9300-48T may be more cost-effective
- You need fiber downlinks → consider C9300X-24Y-E
- You need fixed uplinks instead of modular uplinks → choose a platform designed around fixed uplink ports
TL;DR
C9300X-48TX-E is a Cisco Catalyst 9300X enterprise switch with 48× data-only multigigabit copper ports supporting up to 10Gbps, modular high-speed uplinks, StackWise-1T, Cisco IOS XE, and Network Essentials licensing — ideal for high-bandwidth campus access where PoE is not required.
