C9300-24UXB-E= Use Case
Smart Building IoT Backbone with C9300-24UXB-E=-SPARE Catalyst 9300 Switch
In a 300,000 ft² commercial smart building deploying 400+ IoT sensors, IP cameras and Wi-Fi 6 access points, facilities IT installed the C9300-24UXB-E=-SPARE Catalyst 9300 24-port deep-buffer mGig PoE++ switch as the edge aggregation layer. Deep packet buffers eliminate video-analytics jitter, multi-gigabit ports support bursty wireless traffic, and PoE++ delivers up to 60 W per port. Outcome: 30 % reduction in packet loss, unified power and data management, and seamless scale-out for future smart services.
Retail Edge Computing with Catalyst 9300 24-Port Deep Buffer mGig PoE Switch
A nationwide retail chain deployed the C9300-24UXB-E=-SPARE Catalyst 9300 at each store’s edge to aggregate point-of-sale terminals, digital signage servers and Wi-Fi hotspots. Multi-gigabit uplinks to local servers cut transaction latency by 40 %, while deep buffers absorb traffic surges during peak shopping hours. Integrated PoE++ powers LED displays and edge compute nodes without additional wiring. Benefit: 25 % faster checkout times, reduced rack footprint and streamlined store rollouts.
Secure Campus VLAN Segmentation for Financial Services
A mid-tier investment firm implemented C9300-24UXB-E=-SPARE Catalyst 9300 switches across trading floors and office wings to enforce micro-segmentation and secure guest access. The 24-port deep-buffer design ensures lossless data replication to off-site vaults, while mGig links connect to data center spine switches at wire-rate. PoE++ powers IP phones with redundant power feeds, and built-in MACsec and dynamic ARP inspection protect against lateral attacks. Outcome: Zero network breaches in 12 months, simplified compliance audits and centralized policy enforcement via Cisco DNA Center.
