FAQs

Q: What is the port configuration of the C9350-48HXN?
A: The C9350-48HXN provides 48 multigigabit ports: 36 ports support speeds up to 5 Gbps (10/100/1000/2.5G/5G), and 12 ports support speeds up to 10 Gbps (10/100/1000/2.5G/5G/10G). All ports are RJ45 copper and support 90W UPOE+ power delivery simultaneously.

Q: How much PoE power can the C9350-48HXN deliver?
A: The C9350-48HXN supports 90W UPOE+ (IEEE 802.3bt Type 4) on all 48 ports at the same time, with a maximum PoE budget of 4320W when configured with appropriate power supplies. This makes it ideal for powering high-demand devices like Wi-Fi 7 access points, PTZ cameras, and IoT endpoints.

Q: Can the C9350-48HXN be stacked with other C9350 switches?
A: Yes, the C9350-48HXN features StackWise-1.6T technology, allowing up to 8 switches to be stacked with 1.6 Tbps of total stack bandwidth. A stack can support up to 448 multigigabit ports and 384 UPOE+ ports, managed as a single logical unit with distributed forwarding.

Q: What uplink options are available for the C9350-48HXN?
A: The C9350-48HXN has one modular network uplink slot that supports C9350-NM-2C (2x 100G QSFP28) or C9350-NM-8Y (8x 25G SFP28) modules, providing up to 200G of total uplink bandwidth. This flexible design supports seamless migration from 10G to 25G/100G core connections as traffic demands grow.

Q: Is the C9350-48HXN suitable for Wi-Fi 6E and Wi-Fi 7 deployments?
A: Yes, the C9350-48HXN is purpose-built for next-generation wireless deployments. Its multigigabit ports provide 2.5G/5G/10G backhaul speeds required by Wi-Fi 6E and Wi-Fi 7 access points, and the 90W UPOE+ per port ensures sufficient power for high-performance APs without requiring external power injectors.
