Cisco C9300X-48HX-A — Catalyst 9300X 48-Port 10G Multigigabit UPOE+ Switch with Network Advantage
What it is
C9300X-48HX-A is a Cisco Catalyst 9300X Series high-performance enterprise access switch designed for campus networks that need very fast copper access, high-power PoE, advanced routing, and high-speed modular uplinks.
It provides 48 × multigigabit RJ-45 ports, with every port supporting 100M / 1G / 2.5G / 5G / 10G, plus Cisco UPOE+ up to 90W per port. The “-A” version includes the Network Advantage software tier.
Why buyers pick C9300X-48HX-A (plain English)
48 ports up to 10Gbps: Every copper access port can run at up to 10 Gigabit Ethernet, making it ideal for Wi-Fi 6/6E access points, high-performance workstations, servers, and other bandwidth-heavy devices.
Up to 90W UPOE+ per port: Provides enough power for demanding endpoints such as high-end wireless APs, PTZ cameras, digital displays, and other high-power PoE devices.
Advanced Network Advantage features: The -A license gives you a broader Layer 3 feature set than Network Essentials, making it better suited to complex enterprise networks.
1 Tbps stacking: Cisco StackWise-1T provides extremely high stack bandwidth and lets multiple Catalyst 9300X switches operate as one logical system.
Flexible high-speed uplinks: The modular uplink slot supports C9300X network modules for 10G, 25G, 40G, and 100G connectivity.

Where it fits (and when to choose something else)
Perfect for:
- Wi-Fi 6 / Wi-Fi 6E access points
- High-density enterprise campus access
- Devices requiring 2.5G / 5G / 10G
- High-power PoE endpoints
- PTZ cameras and smart-building devices
- Large enterprise networks
- Deployments requiring advanced Layer 3 routing
- Networks needing 25G / 40G / 100G uplinks
Choose something else if:
- You only need Network Essentials → choose C9300X-48HX-E
- You don't need PoE → choose C9300X-48TX-A
- You only need some 10G multigigabit ports → consider C9300X-48HXN-A
- You only need standard 1G PoE access → a regular Catalyst 9300 may be more cost-effective
- You need even greater core/distribution capacity → consider a Catalyst 9500 / 9500X
TL;DR
C9300X-48HX-A is a Cisco Catalyst 9300X enterprise switch with 48 × 10G-capable multigigabit RJ-45 ports, UPOE+ up to 90W per port, modular high-speed uplinks, 1.76 Tbps switching capacity, StackWise-1T, and Network Advantage licensing — built for high-density, high-power enterprise access networks.
