C9300X-48HX-A Description
The Cisco Catalyst C9300X-48HX-A is the industry's most powerful fixed enterprise access switch, engineered to unleash the full potential of Wi-Fi 6E and high-bandwidth IoT. As the flagship model of the Catalyst 9300X series, it features 48 Multigigabit (mGig) ports that support speeds of 10G, 5G, 2.5G, 1G, and 100M. Every single port is capable of delivering 90W UPOE+ power, making it the ultimate solution for powering and connecting high-performance access points, immersive video endpoints, and advanced building sensors.
Powered by the next-generation UADP 2.5sec ASIC, this switch offers double the crypto bandwidth and CPU power of previous generations. It runs on the Network Advantage license, enabling full core routing (BGP, MPLS), Application Hosting (Cisco ThousandEyes), and complete SD-Access fabric roles. With StackWise-1T technology, it delivers a staggering 1 Terabit per second of stacking bandwidth, providing the scale, speed, and resilience required for the most demanding digital enterprises for the next decade.

Key Features
Wi-Fi 6E Ready. Features 48 ports that support 100M, 1G, 2.5G, 5G, and 10G speeds. This ensures you can connect the latest Wi-Fi 6E Access Points at their full multi-gigabit speeds over existing Cat5e/Cat6 cabling, eliminating bottlenecks at the wireless edge.
Maximum Power Density. Delivers IEEE 802.3bt Type 4 (90W) power on all 48 ports simultaneously (requires adequate power supplies). This capability allows the switch to power entire floors of smart building devices, from high-lumen LED lighting to heavy-duty motorized shades and PTZ cameras.
Terabit Scalability. Introduces the industry’s first 1 Tbps stacking bandwidth. This massive backplane capacity ensures that even when 8 switches are stacked, there is zero oversubscription or blocking for cross-stack traffic, making it ideal for high-density 10G aggregation.
Future-Proof Core Connection. Supports the C9300X-NM network modules, offering dual-rate 100G/40G uplinks. This allows the access layer to connect to the distribution or core layer at data center speeds, accommodating the explosion of video and cloud data traffic.
Smart Edge. With doubled CPU power and 16GB of DRAM, this switch can natively run complex containerized applications. It comes with Cisco ThousandEyes Network and Application Synthetics pre-installed, giving IT teams instant visibility into user experience and cloud application performance.
Secure Interconnect. The UADP 2.5sec ASIC provides line-rate IPsec encryption (up to 100 Gbps) directly on the switch. This allows organizations to extend secure Layer 3 VPNs over the internet or WAN without needing a separate dedicated security appliance.
Application Scenarios
High-capacity, multigigabit edge for global corporations, branch networks, and distributed office buildings, delivering secure LAN services and high-density connectivity.
Power and connect PoE sensors, digital signage, surveillance cameras, access control systems, and environmental monitors—ideal for intelligent campuses, smart factories, and automated facilities.
Converged access for VoIP phone systems, Wi-Fi 6/6E access points, video conferencing, and cloud-hosted collaboration platforms, accelerating digital workspace and hybrid-cloud deployments.

Selection Guide
- Requirement for Wi-Fi 6E/7
Select this model if you are deploying Wi-Fi 6E access points. Standard 1G ports will bottleneck these APs. The 48 mGig ports (up to 10G) ensure that the wired network is not the limiting factor for your high-speed wireless network. - Future-Proof 100G Backbone
Choose this X-series model if your core network is moving to 40G or 100G. The ability to use C9300X-NM modules provides a direct 100G fiber path from the access closet to the core, bypassing distribution layers if needed. - High-Density 90W Power Needs
If you need to power a full building of 90W devices (lighting, displays), this switch is essential. Paired with dual 1900W power supplies, it offers the highest PoE density in the industry, far exceeding the capabilities of the standard C9300 models. - High-Performance Security
For organizations requiring line-rate encryption, the C9300X hardware IPsec capability allows for secure, encrypted tunnels at speeds up to 100 Gbps, ideal for secure campus interconnects or high-speed WAN extensions.
