Keep power-hungry endpoints online with a Catalyst 9300 access switch built for dense campus aggregation. The 48-port UPOE design supports phones, access points, cameras, and other PoE devices from a single switch, reducing the need for local injectors and simplifying rack design. A 1,100 W AC power supply gives this model the headroom needed for mixed-power deployments where uptime and port density matter. With Meraki management, this switch fits teams that want centralized visibility and policy control across distributed sites without sacrificing the control expected from Cisco campus infrastructure. It is a strong fit for organizations standardizing on the Catalyst 9300 family for access-layer consistency, segmentation, and operational scale. This configuration is aimed at environments where downtime is expensive and port oversubscription is not an option. It gives procurement and infrastructure teams a clear path to support more devices per rack unit while preserving the management model and reliability associated with enterprise Cisco switching.
