CISCO C9300-24S-A Catalyst 9300 Series Switches

Twenty-four-port fiber access with Advantage

C9300-24S-A is a Cisco Catalyst access switch with 24 1G SFP access ports with a separately selected modular uplink network module. Its A suffix selects Network Advantage; it does not change the physical port layout.

Exact port acceptance

Use the Network Advantage order when the design has verified advanced routing, segmentation, resiliency or security requirements. Keep the 24 access optics, uplink module and uplink optics as distinct bill-of-material items.

Fiber-access optic matrix

Build an access-side optic matrix for all twenty-four SFP ports, including wavelength, connector, fiber class, transmit/receive levels and peer. Keep that matrix separate from the modular uplink inventory so a failed access optic is not replaced with an unsupported uplink part.

License boundary

Network Advantage is the higher default perpetual Network Stack tier; verify the exact advanced routing, segmentation, resiliency and MACsec features required by the design.

Stack and power boundary

Catalyst 9300 modular platform with StackWise-480 and StackPower support. No copper PoE access-port claim; verify installed power supplies and optic load. Capture PSU, fan, stack-cable and stack-power PIDs and verify the target IOS XE release before mixing members.

Receiving evidence

Record exact PID, serial, installed license state, access transceivers or copper links, every uplink optic, switch-port tests and configuration backup. Fixed-uplink C9300L models and modular-uplink C9300 models are not interchangeable based only on a shared 24-port count.
