  • MACsec-capable ports secure data in flight
  • Dual-persona hardware runs multiple operating systems
  • AI-driven analytics reduce troubleshooting time

48-port gigabit switch with stacking

The Extreme Networks 5520-48T-BASE is a fixed-configuration switch with 48 ports supporting 10/100/1000BASE-T operation. It includes two stacking or QSFP28 ports for uplink flexibility and a single unpopulated VIM slot for future expansion. The unit ships with three unpopulated modular fan slots and two unpopulated modular power supply slots.

Suited for managed campus access

Organisations managing wired access layers through Extreme Platform ONE, ExtremeCloud IQ or ExtremeCloud IQ Site Engine will benefit from fabric-enabled provisioning and AI-assisted troubleshooting. The dual-persona Universal Hardware allows a choice of operating system. Buyers who need pre-installed fans or power supplies, or who require populated uplink modules out of the box, should look at other configurations.

Two QSFP28 stacking ports decide uplink density

The presence of exactly two QSFP28 ports that double as stacking links determines how many high-speed uplinks or stack members can be connected without adding a VIM module. If a design calls for more than two such links, an additional VIM must be sourced separately.

What speed do the 48 BASE-T ports cap at in practice?

The 48 ports run at 10, 100 or 1000 Mbps, full or half duplex, with MACsec capability on each port.

What physical space and slots does the chassis need?

It has one unpopulated VIM slot, three unpopulated modular fan slots and two unpopulated modular PSU slots in a fixed chassis.

How do the two QSFP28 stacking ports get used during install?

Insert compatible QSFP28 transceivers or direct-attach cables into the two stacking ports to build the fabric stack.
