The 7520 family features models with 48 SFP28 ports for 10G and 25G access, along with 6 QSFP28 uplinks supporting 40G or 100G speeds. Breakout options allow these uplinks to be subdivided into multiple 25G or 10G channels, delivering the flexibility required for mixed environments or incremental upgrades. This combination of dense 25G access and 100G-ready uplinks makes the 7520 an excellent fit for leaf-spine designs, large campus aggregation, or data center deployments.

Running on Extreme’s modern operating system, the 7520 provides advanced Layer 2 and Layer 3 services, IPv4 and IPv6 routing, ACL-based security, and robust Quality of Service. Integrated telemetry and analytics give administrators real-time visibility into traffic flows, while automation tools simplify provisioning and lifecycle management. Redundant power supplies, hot-swappable fans, and multiple airflow options ensure continuous operation in mission-critical networks.
