Cisco C9300X-48HX-A | Catalyst 9300X 48-Port 10G mGig Switch, 590W UPoE+, 2x 100G

Q: What network modules are compatible with the C9300X-48HX-A?
A: The C9300X-48HX-A supports Catalyst 9300X network modules including C9300X-NM-2C (2x 100G), C9300X-NM-4C (4x 100G/40G), C9300X-NM-8Y (8x 25G), and C9300X-NM-8M (8x mGig). It also supports standard C9300 modules like C9300-NM-8X (8x 10G), C9300-NM-2Q (2x 40G), and C9300-NM-4M (4x mGig). The C9300X-NM-4C is compatible only with C9300X-48HX, C9300X-48TX, and C9300X-24Y models.

Q: Can the C9300X-48HX-A be stacked with other Catalyst 9300 models?
A: Yes, the C9300X-48HX-A supports StackWise-1T for stacking up to 8 switches with 1 Tbps bandwidth. It can be mixed-stacked with Catalyst 9300 and other 9300X models at StackWise-480 speeds. However, it cannot be stacked with C9300L fixed uplink models or Catalyst 3850/3650 series switches.

Q: How many devices can receive full 90W UPoE+ power simultaneously?
A: With the default 1100W power supply providing a 590W PoE budget, approximately 6 ports can receive full 90W UPoE+ simultaneously. For higher density, add a second 1100W PSU to increase the PoE budget, or use StackPower+ to share power across stacked switches for greater flexibility.

Q: What license is required to operate this switch?
A: The C9300X-48HX-A includes a perpetual Network Advantage license, providing Layer 3 routing (OSPF, EIGRP, BGP, MPLS), advanced security features, application hosting, and full SD-Access fabric support. A separate Cisco DNA subscription (Essentials or Advantage) is optional for analytics, automation, and assurance features.

Q: What are the primary use cases for this switch?
A: Ideal for high-density Wi-Fi 6/6E access point deployments, IoT convergence, advanced building automation, high-performance IP surveillance, and campus aggregation layers. The 90W UPoE+ per port supports power-hungry devices like next-gen wireless APs, PTZ cameras, digital signage, and telepresence endpoints.
