The device belongs to the Extreme 7520 series - a universal hardware platform offering deployment flexibility, high scalability, and advanced security and network automation features.

This model supports 48 × 1/10/25GbE fiber ports in the SFP28 standard and 8 × QSFP28 uplink ports supporting 40/100GbE, making it ideal for high-throughput environments handling intensive traffic in data centers and campus networks.

The Base Unit version is delivered as a base system with empty slots for power supplies and fan modules, allowing configuration to be tailored to specific infrastructure requirements. The package includes a 4-post rack mount kit.

The switch features a non-blocking architecture with switching capacity up to 4 Tbps, low latency, and a forwarding performance of up to 1000 Mpps. The Universal Hardware platform enables the choice of operating system - Switch Engine (EXOS) or Fabric Engine (VOSS) - both at initial deployment and later during operation.

The device can be managed via cloud or locally using Extreme Platform ONE, ExtremeCloud IQ, as well as CLI and GUI interfaces. Support for Extreme Fabric enables network automation, microsegmentation, and secure onboarding of new devices into the infrastructure.
