C9350-24U Description
Cisco C9350-24U is a 24-port Gigabit UPoE enterprise access switch designed for power-dense campus edge deployments. It provides up to 60W per port to support modern Wi-Fi, collaboration endpoints, and security devices while keeping wiring-closet design simple.
With modular uplink network modules and high-performance StackWise-1.6T stacking, C9350-24U helps you scale uplinks and resiliency without redesigning the access layer. It is a practical choice for organizations upgrading from C9300 UPoE access networks and standardizing on the Catalyst 9350 platform.

Key Features
Built for power-hungry access edge designs
C9350-24U is designed for environments where standard PoE+ is not enough, allowing high-power devices to be deployed without external power injectors or redesigning the access layer.
Fewer ports, cleaner access layer architecture
By offering 24 UPoE ports instead of high port density, this model helps avoid overloading wiring closets with unnecessary ports while maximizing usable power per connection.
Reduces dependency on external power infrastructure
High per-port power delivery simplifies deployments in areas where adding electrical outlets or midspan power equipment is costly or impractical.
Optimized for next-generation endpoint evolution
As edge devices continue to demand more power and bandwidth, C9350-24U provides headroom for future device upgrades without replacing the access switch.
Designed for operational stability in critical areas
High-performance stacking and power sharing capabilities ensure that critical powered devices remain online during maintenance or partial hardware failures.
Strategic platform choice for long-term campus planning
Choosing C9350-24U helps standardize on a next-generation access platform, reducing future migration complexity as networks evolve.
Applications Scenarios
High-end wireless deployments with limited port requirements
Ideal for areas where a smaller number of wireless access points require higher power levels, such as executive offices, large meeting spaces, or premium office floors.
Collaboration and AV-focused environments
Well-suited for rooms equipped with advanced video conferencing systems, smart displays, and integrated audio-visual equipment that depend on higher PoE power delivery.
Smart building and specialized IoT edge scenarios
Commonly used in smart buildings where controllers, gateways, and edge devices draw more power than typical PoE endpoints, enabling cleaner installations without additional power sources.
