24-port SFP+ managed switch

The Extreme Networks 5520-24X-ACDC-BASE is a managed switch offering 24 ports that operate at 1Gb or 10Gb speeds via SFP+ transceivers. It includes two stacking or QSFP28 ports for high-density uplinks or switch stacking. The unit suits network engineers building 10Gb aggregation layers in campus or data-centre racks.

Verify SFP+ optics and power options

Confirm you have compatible SFP+ modules for the 24 front-panel ports and decide whether to use QSFP28 optics or direct-attach cables for the two stacking ports. The chassis ships with two unpopulated modular PSU slots, so you must order AC or DC power supplies separately. One vacant VIM slot is available for future feature expansion.

Modular cooling and redundant power

Three unpopulated modular fan slots let you install the airflow configuration your rack requires, while the dual PSU bays enable redundant power once supplies are fitted. The stacking ports free uplink bandwidth on the SFP+ ports by handling inter-switch links. No transceivers, fans or power supplies are included in the box.

Questions about this item

Does the 5520-24X-ACDC-BASE ship with SFP+ transceivers, fans or power supplies, or must they be ordered separately?

The unit includes 24 SFP+ ports, two QSFP28 stacking ports, one empty VIM slot, three empty fan slots and two empty PSU slots; transceivers, fan modules and AC or DC power supplies are not included and must be purchased separately.

How do I choose between AC and DC power for this 5520 switch?

The chassis accepts either AC or DC modular power supplies; select the PSU type that matches your rack power infrastructure and buy the corresponding power supply modules for the two open slots.

What does the 10Gb SFP+ rating mean for actual throughput on this 5520 model?

Each of the 24 ports supports 1Gb or 10Gb line-rate switching; real-world throughput depends on the transceivers and cables you install and the traffic profile on your network.
