​​Addressing Core Enterprise Concerns​​
​​Q: Can this switch power 48 PoE+ devices simultaneously without oversubscription?​​
Yes. The ​​1,170W budget​​ supports 48x ​​30W devices​​ (e.g., Cisco 9124AX APs) at full load, leaving no risk of power starvation.
​​Q: Is it compatible with older PoE devices like IP phones or sensors?​​
Absolutely. Backward compatibility with ​​IEEE 802.3af (PoE)​​ ensures seamless integration with legacy devices.
​​Q: How does StackWise-160 benefit distributed deployments?​​
By creating a ​​single management domain​​ across 384 ports, it simplifies configuration and monitoring for multi-building campuses.

​​Why This Switch Excels in Legacy-to-Modern Transitions​​
In a recent smart warehouse deployment, the ​​C9200-48PB-A​​ powered ​​200+ legacy barcode scanners​​ and ​​60 Wi-Fi 5 APs​​ without requiring mid-span injectors or power upgrades. While the 24PXG-10E caters to cutting-edge Wi-Fi 6E, the 48PB-A’s ​​pure 1G PoE+ design​​ offers unmatched cost efficiency for organizations phasing out older IoT systems. Its ​​DNA Essentials licensing​​ also streamlines compliance audits—a critical factor for industries like logistics where uptime and regulatory adherence are non-negotiable. For enterprises balancing legacy device support with moderate scalability, this model is a workhorse that prioritizes reliability over bleeding-edge speeds.
