Deployment Scenarios and Industry Applications

• Small Wiring Closets and Branch Offices: The primary use case for the 24ZY4 — full Cognitive Campus capability in a 24-port form factor for locations that don’t need 48 ports but do need multi-gigabit speeds and enterprise-class features.
• WiFi 6/6E Access Point Connectivity: The 8 × 5GbE ports with 60W 802.3bt PoE are purpose-built for high-performance wireless access points, while the 16 × 2.5GbE ports handle standard APs and wired devices — all without the 1GbE bottleneck.
• Retail and Hospitality: A right-sized switch for individual store locations or hotel floors — PoE-powered point-of-sale devices, digital signage, and guest WiFi access points managed through CloudVision alongside the rest of the campus.
• Video Surveillance and Physical Security: 802.3bt 60W PoE on 5G ports powers advanced PTZ cameras and multi-sensor devices, while Persistent PoE maintains power during switch reboots — critical for mission-critical security infrastructure.
• Healthcare Clinics and Satellite Offices: 802.1X authentication and VXLAN segmentation isolate medical devices and patient networks from administrative systems, with the same security and telemetry capabilities as the main campus.
• Education — Classrooms and Labs: Multi-gigabit ports support bandwidth-intensive lecture capture, interactive whiteboards, and high-density student WiFi, with VRF segmentation keeping student, faculty, and IoT traffic isolated.
