CN12900-SUP-CV=: Why Is This Cisco Supervisor
Core Functionality and Design The Cisco CN12900-S...
The C9200-24P-A++ is a Cisco Catalyst 9200 Series switch optimized for high-power PoE++ deployments. It features 24x Multi-Gigabit Ethernet ports (10/100/1000/2500/5000 Mbps) with 802.3bt PoE++ support, delivering 90W per port and a total PoE budget of 1.8 kW. Key specs include:
The C9200-24P-A++ prioritizes power density over port count, making it ideal for environments requiring fewer but higher-power devices. Unlike the 48-port model:
Enterprise campuses: Powers C9130AXI Wi-Fi 6E APs and Cisco Webex Room Kits in conference halls without separate power runs.
Healthcare: Supports PoE++-enabled medical devices like patient monitors and mobile imaging carts with 99.999% uptime.
Retail: Drives 4K digital signage, AI-powered inventory robots, and POS systems on a single infrastructure.
Q: Can it power non-PoE devices alongside PoE++ equipment?
A: Yes. The switch auto-detects power requirements, allocating 30W/60W/90W per port as needed.
Q: What cooling is required for 90W PoE++?
A: The C9200-24P-A++ uses variable-speed fans—ensure ambient temps stay below 45°C for optimal thermal management.
Q: How does MACsec enhance security?
A: Encrypts data at Layer 2 between switches and endpoints, critical for defense or financial networks.
Purchase the C9200-24P-A++ through authorized vendors like [“C9200-24P-A++” link to (https://itmall.sale/product-category/cisco/). Pair with C9300 switches for StackWise-320 redundancy and DNA Center 2.3.3+ for AI-driven power analytics.
The C9200-24P-A++ eliminates midspan injectors in high-power setups, but its 1.8 kW draw demands careful circuit planning. In my experience, teams often overlook phase balancing in three-phase power environments, risking overloads. For industrial IoT deployments, its Class 6 surge protection is invaluable, but only if ground connections are rigorously tested. While the 24-port limit seems restrictive, its ability to daisy-chain C9136I-ROW APs via multi-gig uplinks makes it a stealth backbone for outdoor smart campuses—provided cooling vents aren’t blocked in enclosed racks.
