Cisco C9300X-48TX-A | Catalyst 9300X 48-Port 10G Multigigabit Switch, Network Advantage

Q: What is the difference between the C9300X-48TX-A and the C9300X-48HX-A?
A: The C9300X-48TX-A is a data-only switch without Power over Ethernet capability, while the C9300X-48HX-A includes 90W UPOE+ on all 48 ports for powering high-demand devices like Wi-Fi 6E access points and IoT sensors. Both share the same 10G multigigabit port speeds and modular uplink architecture.

Q: Can I mix C9300X switches with older Catalyst 9300 models in a stack?
A: Yes, mixed stacking between Catalyst 9300X and Catalyst 9300 models is supported at StackWise-480 speeds. However, you cannot mix C9300X/C9300 modular uplink models with C9300L fixed uplink models or higher-scale UB models in the same stack.

Q: What uplink modules are compatible with this switch?
A: The C9300X-48TX supports optional network modules including 8-port 25G SFP28, 4-port 40G QSFP+, and 2-port 100G QSFP28 modules. The C9300X-NM-4C module (compatible with the 48TX model) provides 4 ports of 100G connectivity for high-bandwidth uplinks to distribution or core layers.

Q: Does this switch require a DNA subscription?
A: The C9300X-48TX-A includes a perpetual Network Advantage license tied to the hardware. While optional, a Cisco DNA Advantage subscription unlocks additional cloud management, analytics, and security features through Cisco DNA Center. The switch can also be migrated to Meraki Dashboard management.

Q: What are the key security features of the C9300X series?
A: The C9300X-48TX-A is built on the UADP 2.0sec ASIC, featuring 100 Gbps hardware-based IPsec for secure VPN tunnels and AES-256 MACsec for link-level encryption. It supports advanced security features including TrustSec, Encrypted Traffic Analytics, and secure segmentation for zero-trust architectures.
