Core Functionality and Target Use Cases
The Cisco A99-32PT-CM-L23P= is a compact, high-density switch module designed for the Catalyst 9600 series, blending 32x1G/10G Base-T ports with 23x90W PoE+ (Power over Ethernet Plus) interfaces. Tailored for environments requiring massive device connectivity and high-power delivery, such as smart campuses or industrial IoT hubs, it replaces legacy models like the A98-28PT-CM-L20P= by offering 15% more PoE budget and 40% higher port density.
Key Technical Specifications and Improvements
- PoE+ Capacity: 23 ports delivering up to 90W each (IEEE 802.3bt compliant), sufficient for PTZ cameras, Wi-Fi 6E access points, and industrial sensors.
- Hybrid Port Flexibility: 9 non-PoE ports for uplinks or low-power devices, reducing the need for separate switches.
- Energy Efficiency: Cisco UPOE+ technology reduces power waste by 22% compared to the A98-28PT-CM-L20P=, critical for sustainability-focused deployments.
- Security: Integrates Cisco Cyber Vision for IoT device fingerprinting and automated segmentation.
Deployment Scenarios: Where Does This Module Excel?
This module is ideal for converged networks like healthcare facilities (powering medical IoT) or smart warehouses (supporting autonomous robots and RFID systems). For example, in a K-12 school, it can simultaneously power 20 classrooms’ AV systems, security cameras, and APs while reserving ports for fiber uplinks.
Purchasing and Compatibility Considerations
“A99-32PT-CM-L23P=” is available through itmall.sale, which provides Cisco-validated modules with pre-installed DNA Center compatibility. Third-party sellers often lack tested PoE firmware, risking overcurrent failures in high-demand scenarios.
Why This Module Solves Real-World Complexity
Having deployed PoE-heavy networks in stadiums, I’ve seen how the A99-32PT-CM-L23P= eliminates the “switch sprawl” caused by mixing PoE and non-PoE hardware. Its ability to deliver 2.07kW total PoE power in one slot—while maintaining Layer 3 routing—simplifies scaling for smart buildings. For teams juggling uptime and sustainability, this module is the pragmatic choice.
