2. Product Overview

Cisco Catalyst C9300-24S-A is a 1U rackmount enterprise stackable Layer3 fiber aggregation switch running native Cisco IOS XE OS, mainly deployed for campus distribution layer, fiber closet aggregation and branch core networking to aggregate multiple remote wiring closets via long-distance fiber links beyond 100m copper limit. It supports StackWise-480 physical stacking and StackPower+ cross-chassis power pooling architecture for redundant power resource sharing among stacked units.

Port & Power Specifications

Downlink: 24×Hot-pluggable Gigabit SFP slots for flexible fiber transceiver deployment; no built-in PoE, no inline power budget allocated for endpoints
Rear modular uplink expansion slot supporting dedicated C9300 uplink network modules: C9300-NM-8X(8×10G SFP+), C9300-NM-4Y(4×25G SFP28), C9300-NM-2Q(2×40G QSFP+), flexible uplink bandwidth scaling from 1G up to 40Gbps for future network upgrade
Default factory pre-install single PWR-C1-715WAC universal AC power supply; hot-swappable redundant second 715WAC PSU optional for fully redundant power architecture; StackPower+ enables cross-stack power load balancing between stacked switches
