48-port managed switch

The Extreme Networks 5520-48T-ACDC-BASE is a managed switch with 48 fixed ports supporting 10/100/1000 speeds and MACsec capability. It includes two stacking or QSFP28 ports for uplink or fabric connectivity. The unit is designed for commercial networks requiring automated provisioning and cloud-based management through Extreme Platform ONE or ExtremeCloud IQ.

Installation and common issues

The switch ships with three unpopulated modular fan slots and two unpopulated modular PSU slots, so fans and power supplies must be sourced and installed before deployment. A single unpopulated VIM slot is available for optional expansion modules. Ensure the selected power supplies match the available AC or DC input at the installation site.

Pre-order checks

Verify that your rack provides adequate airflow for the modular fan configuration you plan to use. Confirm the management platform you intend to run — Extreme Platform ONE, ExtremeCloud IQ or ExtremeCloud IQ Site Engine — is licensed and ready for device onboarding. Check that any required stacking cables or QSFP28 transceivers for the two uplink ports are on hand before the switch arrives.
