3. Complete Product Overview Paragraph
The Cisco Catalyst C9300X-48HXN-E is a fixed-form-factor dense mixed-speed multigigabit UPOE+ stackable Layer 3 enterprise access switch within the Catalyst 9300X series, optimized for budget-oriented modern office, retail, classroom, smart building and industrial wired deployments that require a split port mix of premium full 10G multigigabit and economical 5G multigigabit ports, plus universal maximum 90W UPOE+ power delivery to next-generation wireless access points, high-end PTZ surveillance cameras, large-format digital signage and power-intensive industrial IoT terminals without full premium enterprise feature setsCisco. Equipped with 8 dedicated 10G-capable and 40 cost-optimized 5G-capable multigigabit UPOE+-capable RJ45 downlink ports, all supporting auto-negotiated speeds from 100Mbps up to their maximum rated rate and up to 90W per port via four-pair power delivery, 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 elastic bandwidth scaling to aggregation and core switching layers. Powered by UADP 2.0sec crypto ASIC with hardware crypto acceleration for line-rate 100G IPsec tunnels, this model runs native IOS XE with permanent Network Essentials license, delivering fundamental Layer 2 switching and constrained Layer 3 routing functions while disabling all advanced premium features reserved for Network Advantage licensed hardware variants. It leverages StackWise-1T hardware stacking to combine up to 8 identical C9300X switches into a unified logical switching fabric with 1 Tbps aggregate stacking bandwidth, achieving sub-50ms fast stack failover convergence for enterprise-class network reliability. Native StackPower technology dynamically aggregates power supplies across the entire stack for shared UPOE+ power pooling, power redundancy and automatic load redistribution during hardware failure events. Dual hot-swappable AC power supply slots and field-replaceable variable-speed fan trays eliminate single points of hardware failure. The switch only supports limited on-premises management via console CLI, SNMPv3 or basic Cisco Catalyst Center integration (Meraki cloud native firmware is not supported for this on-prem IOS XE model). It comes with basic zero-touch provisioning and sampled traffic monitoring, built for mid-size hybrid campus mixed-density multigigabit UPOE+ access environments without demand for advanced zero-trust security, full streaming analytics or end-to-end SD-Access fabric automation.
