Built on Cisco’s ​​DNA architecture​​, it supports ​​SD-Access​​ for automated network segmentation and ​​Cisco Stealthwatch​​ for advanced threat detection.

Key specs include ​​360 Gbps switching capacity​​, ​​StackWise-320 technology​​, and ​​EnergyWise compatibility​​ for real-time power monitoring. The ​​E=​​ suffix indicates ​​network essentials licensing​​, providing foundational security and management features out-of-the-box.

​​Target Use Cases and Industry Applications​​

This switch is ideal for ​​enterprise campuses​​, ​​healthcare networks​​, and ​​higher education institutions​​ requiring scalable connectivity and robust PoE capabilities. Its ​​front-to-back airflow design​​ ensures efficient cooling in densely packed racks, while ​​PoE+ support​​ (on 24 ports) powers devices like IP cameras, wireless APs, and digital signage.

​​Addressing Critical Deployment Questions​​

• ​​Q: What is the total PoE budget, and how many devices can it support?​​
  The switch delivers ​​740W total PoE+ budget​​, supporting up to 24x 30W devices (e.g., PTZ cameras) or 48x 15.4W endpoints (e.g., VoIP phones).

• ​​Q: How does it handle high-speed data aggregation?​​
  The ​​4x 25G uplinks​​ provide low-latency connectivity for backbone links, reducing bottlenecks in scenarios like real-time data analytics or cloud backups.

• ​​Q: Can it scale with growing network demands?​​
  ​​StackWise-320​​ allows up to eight switches to operate as a single unit, enabling non-disruptive capacity expansions.
