Cisco C9300-24S-E — Catalyst 9300 24-Port 1G SFP Switch with Modular Uplinks and Network Essentials
What it is
C9300-24S-E is a Cisco Catalyst 9300 Series enterprise switch designed for fiber-based access, aggregation, and campus deployments that need 24 × 1 Gigabit SFP ports with modular high-speed uplinks.
It runs Cisco IOS XE, supports StackWise-480 and StackPower, and the “-E” version includes the Network Essentials software tier. Cisco ships it with a 715W AC power supply installed by default.
Why buyers pick C9300-24S-E (plain English)
24 fiber access ports: Ideal for environments where endpoints or downstream switches connect over 1G fiber instead of copper.
Modular uplinks: The uplink module is selected separately, so you can choose the uplink configuration that best fits the network rather than being locked into fixed ports.
Network Essentials licensing: Provides the core enterprise switching and routing capabilities needed for many campus access and aggregation deployments.
StackWise-480: Multiple Catalyst 9300 switches can operate as one logical system with up to 480 Gbps of stack bandwidth.
Enterprise Catalyst platform: Runs Cisco IOS XE with centralized management, telemetry, automation, and security capabilities.
