About the Extreme Networks ExtremeSwitching 5520-48T
The ExtremeSwitching 5520-48T is a versatile 1U enterprise access layer switch offering 48 x 1G RJ45 ports combined with high-speed uplink options including 10G SFP+ and 100G QSFP28 interfaces. It is purpose-built for campus access deployments where simplified management, network fabric integration, and consistent policy enforcement are paramount. The 5520 series runs ExtremeXOS, Extreme's proven network operating system, providing a unified CLI, scripting via Python and TCL, and deep automation hooks.
The 5520-48T supports Extreme Fabric Connect (IEEE 802.1aq SPB), enabling automated Layer 2/3 service provisioning across multi-site campus networks without complex VLAN trunking configurations. Its hardware supports IEEE 802.1X port-based authentication, dynamic VLAN assignment, and policy-based routing tightly integrated with ExtremeControl NAC for zero-trust access enforcement. The switch also supports VXLAN for campus fabric overlays and integrates with ExtremeAnalytics for flow-based visibility.
Management is streamlined through ExtremeCloud IQ, where administrators can leverage AI-driven configuration templates, compliance audits, and real-time performance dashboards. The 5520-48T ships with front-to-back and back-to-front airflow SKUs and supports hot-swappable redundant power supplies, ensuring carrier-class availability for mission-critical enterprise access layers.
Ideal for
- Enterprise campus access layer wiring closet deployments
- Education district network standardization across multiple buildings
- Government and public sector secure network access with NAC integration
- Hospitality guest network segmentation with policy-based access control
- Branch office connectivity with Fabric Connect zero-touch provisioning
- Retrofit of legacy 1G campus networks with a growth path to 10G
