FAQs

Q: What is the difference between the C9300X-48HXN-A and the C9300X-48HX-A?
A: The C9300X-48HXN-A features a mixed port configuration with 40x 5G ports and 8x 10G ports, while the C9300X-48HX-A has all 48 ports capable of 10G speeds. The HXN model provides optimized density for typical enterprise deployments where only some ports require full 10G capability, while maintaining 90W UPoE+ across all ports. Both models support the same modular uplinks and stacking technology.

Q: Can this switch stack with older Catalyst 9300 models?
A: Yes, the C9300X-48HXN-A can stack with Catalyst 9300 and other Catalyst 9300X models using StackWise cables at StackWise-480 speeds for backward compatibility. When stacking with 9300X models exclusively, it operates at full StackWise-1T (1 Tbps) speeds. It cannot stack with C9300L fixed-uplink models or C9300 higher-scale models (C9300-24UB/48UB series).

Q: What uplink modules are compatible with this switch?
A: The C9300X-48HXN-A has one modular uplink slot supporting various network modules including C9300X-NM-8Y (8x 25G SFP28), C9300X-NM-2C (2x 100G QSFP28), C9300-NM-8X (8x 10G SFP+), and C9300-NM-2Q (2x 40G QSFP+). Note that when using the C9300X-NM-8Y module with the HXN model, ports 7 and 8 on the module are disabled due to hardware limitations.

Q: How much total PoE power can be delivered with additional power supplies?
A: The default 1100W PSU provides 690W PoE budget. By adding a secondary power supply, total PoE budget increases to: 940W (with 350W secondary), 1305W (with 715W secondary), 1690W (with 1100W secondary), or 2490W (with 1900W secondary). The 1900W PSU requires 230V input and special C21 power cables.

Q: What advanced features does the Network Advantage license enable?
A: The included Network Advantage license unlocks full Layer 3 routing protocols (OSPF, EIGRP, BGP), MPLS Layer 2/3 VPNs, segment routing, VRF-lite, policy-based routing, enhanced QoS, and application hosting capabilities. It also enables integration with Cisco DNA Center for software-defined access, network assurance, and analytics.
