2. Product Overview
Cisco Catalyst C9300-24S-E is a 1U rack-mount stackable Layer3 fiber aggregation switch running Cisco IOS XE operating system, targeted for campus distribution closet aggregation, long-distance fiber inter-building networking and branch core layer deployment beyond 100m copper transmission limit. Native StackWise-480 physical stacking and StackPower+ cross-chassis power pooling are onboard for high availability deployment.
