The Cisco Catalyst C9300-48U is an enterprise campus access switch built to support dense endpoints and simplify wired connectivity at the edge. With PoE and modular uplinks, it helps teams power demanding devices and keep network design flexible while reducing the need for separate infrastructure.
As wireless density, higher-power endpoints and segmented access demands increase, copper access layers have to support more traffic and more devices without adding operational sprawl.
The Cisco Catalyst C9300-48U is a 48-port access switch for enterprise edge deployments that need multigigabit-ready endpoint support and high-power delivery in one platform. It suits buildings and floors where Wi-Fi, collaboration devices and building systems all depend on the same access layer.
With 48×RJ45 1G ports, a modular uplink, 822 W PoE budget and stacking support, it fits environments that want to extend service over existing copper while keeping switch estates manageable. Dynamic routing adds flexibility where access networks must adapt as layouts and services change.
That combination helps teams consolidate powered devices, reduce the need for separate injectors and small switches, and keep access layers easier to standardise. It also gives infrastructure teams a practical platform for consistent segmentation, cleaner floor-by-floor operation and less manual rework during moves, adds and changes.
If you are planning an access refresh, our team can help assess where the Cisco Catalyst C9300-48U fits and how to deploy it around your current cabling and endpoint mix.
Cisco Catalyst C9300-48U is an enterprise access switching platform for wired campus environments, designed to connect user devices and services with a scalable operational foundation for modern network deployments.
High-Density Wired Access
The switch provides 48 RJ45 1G ports for dense edge connectivity in campus and access-layer deployments.
Modular Uplink Architecture
A modular uplink design lets the platform adapt upstream connectivity to different network requirements.
PoE-Powered Edge Services
An 822 W PoE budget supports powering connected endpoints from the access layer.
Campus Switching Capacity
A 256 Gbps switching capacity supports sustained traffic handling across the access platform.
Integrated Endpoint Power Delivery
Built-in PoE delivery reduces the need for separate power sources at the network edge.
Access-Layer Traffic Handling
The switching design supports forwarding performance suited to enterprise user, voice, and device connectivity.
Deployment Flexibility
The platform architecture supports varied access-layer use cases without changing the core switching role.
If you are aligning access ports, uplinks, and PoE demands across campus sites, our Cisco experts can help match the C9300-48U to your network design.
The Cisco Catalyst C9300-48U is an enterprise access switch for dense copper edge deployments that need multigigabit PoE, stronger power delivery and simpler operations. It fits organisations refreshing high-demand work areas, wireless access and powered devices without redesigning every floor.
Hospitals use this switch where carts, workstations, phones, cameras and Wi-Fi 6 or 6E access points share the same floor. The 48-port density and higher-power access help keep patient, admin and guest traffic separated without adding switch sprawl.
Hotels need dependable edge access in event spaces, guest floors and back-of-house areas that see variable endpoint counts. This model supports dense APs, POS terminals, IPTV and cameras over existing copper, reducing injector clutter during peak occupancy.
Professional services teams often face desk moves, room changes and guest access requests that stretch small access designs. The C9300-48U gives network teams a stable copper access layer for meeting rooms, collaboration spaces and frequent reconfiguration.
Architecture firms move large files and support plotters, review rooms and high-throughput wireless at the same time. This switch is chosen where predictable edge bandwidth matters, but the team still wants a manageable access layer across studio space.
Media teams rely on fast file movement, wireless-heavy collaboration and tightly controlled office connectivity around production areas. The C9300-48U helps keep access services steady for edit bays, review rooms and studio offices without forcing a patchwork of small switches.
Our team can help design and deploy Cisco Catalyst C9300-48U access layers for healthcare, hospitality, professional services, architecture and media environments, with practical support for segmentation, port planning and rollout across occupied sites.
