What it is: A stackable, enterprise L3 Catalyst 9300 with 24 × 10/100/1000 RJ-45 access ports delivering Cisco UPOE (up to 60W/port), plus a modular uplink bay (swap in 1G, 10G, or 40G).

Why buyers pick C9300-24U-E (plain English)

• Power for hungry endpoints: up to 60W/port for Wi-Fi 6/6E APs, PTZ cameras with heaters, thin clients, and lighting/IoT.

• Choose your uplinks: 4×1G, 4×10G, 8×10G, or 2×40G—upgrade later without replacing the chassis.

• Stacks like a pro: StackWise-480 delivers big stack bandwidth and single-IP operations (up to 8 members).

• Stable, modern ops: Network Essentials gives the core routing/security toolset most access layers need.
