3. Complete Product Overview Paragraph
The Cisco Catalyst C9300X-24UX-E is a fixed-form-factor high-density multi-gigabit UPOE+ stackable Layer 3 enterprise switch within the Catalyst 9300X series, optimized for budget-friendly modern campus access deployments requiring multi-speed copper connectivity and high inline power for next-gen wireless access points, video conferencing units, digital signage and high-power surveillance camerasCisco. Equipped with 24 universal auto-sensing multi-gigabit RJ45 UPOE+ downlink ports, the chassis integrates one dedicated hot-swappable C9300X-NM modular uplink slot to flexibly deploy 10G/25G/40G/100G high-speed optical uplink modules for scalable bandwidth expansion. Powered by UADP 2.0sec crypto ASIC with hardware crypto acceleration, this model runs native IOS XE software with permanent Network Essentials license, delivering foundational switching and restricted Layer 3 routing functions while blocking premium enterprise capabilities such as full BGP routing, SD-Access fabric integration, TrustSec zero-trust segmentation and Encrypted Traffic Analytics (ETA)Cisco. It leverages StackWise-1T hardware stacking to interconnect up to 8 identical C9300X units into a single unified logical switching domain with 1 Tbps aggregate stacking bandwidth, delivering sub‑50ms fast stack failover convergence for enterprise-grade resiliency. Built-in StackPower+ technology dynamically pools power supplies across the entire stack for UPOE redundancy, load balancing and power sharing during hardware failover events (supports up to 4 stacked switches for power aggregation). Dual hot-swappable AC power supply slots and field-replaceable variable-speed fan trays eliminate single points of hardware failure. The switch is managed on-premises through console CLI, SNMPv3 or limited Cisco Catalyst Center integration rather than Meraki cloud dashboard, with basic zero-touch provisioning and sampled traffic monitoring built for mid-size copper-fiber hybrid campus infrastructures with moderate high-power PoE device loads and no requirement for advanced security & analytics suites.
