• Efficiency Rating: 80 PLUS Bronze certified power supplies minimize standby power waste.

7. Compatibility & Scalability

• Interoperability: Certified with VMware NSX, Microsoft Azure Stack HCI.

• Future-Proofing: Supports IOS XE 17.x+ (upgradable to 18.x with hardware refresh).

• Hybrid Deployments: Seamlessly integrates with cloud-managed networks (e.g., Meraki MX).

8. Software Ecosystem

• Native Features: NetFlow, SPAN, RSPAN for traffic analysis.

• API Access: Programmable via RESTCONF/YANG for automation (Ansible/Cisco DNA Center).

• Lifecycle Management: Scheduled software updates via Cisco Smart Licensing.

9. Typical Use Cases

• Enterprise Campus Cores: Aggregates traffic from access-layer switches.

• Data Center Edge: Supports VM migration in leaf-spine architectures.

• Industrial IoT: Withstands harsh environments (-40°C to 75°C temperature range).
