The Extreme Networks 5520-24XBASE delivers 24 SFP+ ports that operate at 100 Mb, 1 Gb or 10 Gb speeds. Two additional Stacking/QSFP28 ports provide high-density uplinks or switch stacking. It targets network teams building aggregation layers that need flexible fibre connectivity.

Open VIM slot and dual PSU bays for custom power

One unpopulated VIM slot accepts optional modules to extend port count or media types. Two modular PSU slots let you choose redundant or single-supply power to match rack policies. Two empty fan trays allow airflow tuning for the chassis environment.

Base licence keeps feature set fixed under

The included Base software licence enables core switching functions without recurring fees. All 24 SFP+ ports and both QSFP28 ports sustain line-rate forwarding during prolonged loads. The platform suits deployments that prioritise stable throughput over advanced licensed features.
