Cisco C9300X-48TX-A — Catalyst 9300X 48-Port 10G Multigigabit Data-Only Switch with Network Advantage
What it is
C9300X-48TX-A is a Cisco Catalyst 9300X Series enterprise access switch designed for high-performance campus networks that need 10 Gigabit multigigabit copper access ports 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 “-A” version includes the Network Advantage software tier.
Why buyers pick C9300X-48TX-A (plain English)
48 ports that can run up to 10Gbps: Every copper access port supports multigigabit speeds, making it ideal for high-performance workstations, servers, access points with separate power, and other devices that need more than 1Gbps.
Data-only design: Unlike the HX models, the 48TX does not provide PoE, making it a better fit when powered endpoints are not needed.
Flexible high-speed uplinks: The modular uplink slot lets you choose the C9300X network module that best matches your backbone requirements.
1 Tbps stacking: StackWise-1T provides very high stack bandwidth and allows multiple switches to operate as one logical system.
Network Advantage included: The -A license provides the more advanced routing and enterprise feature set compared with Network Essentials.

Where it fits (and when to choose something else)
Perfect for:
- High-performance enterprise access networks
- 10GbE desktop/workstation connectivity
- Servers connected over copper
- Engineering and media environments
- Networks needing 2.5G / 5G / 10G access
- Customers wanting advanced Layer 3 features
- High-bandwidth StackWise deployments
Choose something else if:
- You need UPOE+ / up to 90W PoE → choose C9300X-48HX-A
- You only need Network Essentials → choose C9300X-48TX-E
- You only need 1G access ports → a standard C9300-48T may be more cost-effective
- You need SFP28 fiber downlinks → consider C9300X-24Y-A
- You need only some 10G copper ports rather than all 48 → consider a mixed-speed Catalyst 9300X model
TL;DR
C9300X-48TX-A 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 Advantage licensing — ideal for high-bandwidth campus access where PoE is not required.
