Edge switch for 10Gb SFP+ uplinks

The Extreme Networks 5520-24X is a managed aggregation switch with 24 unpopulated SFP+ ports running at 100M, 1G or 10G speeds. Two QSFP28 stacking ports and a dedicated RJ-45 management port complete the front panel. It fits a standard 1U rack space and draws up to 171W.

Suited for fibre-heavy wiring closets.

Network teams needing dense 10Gb fibre uplinks from access switches or servers will use every port. Sites that require RJ-45 PoE for phones, cameras or Wi-Fi APs cannot connect those devices directly because no copper ports are present. Buyers wanting pre-installed transceivers must source them separately.

24 SFP+ ports decide the fit

The defining specification is the count of 24 SFP+ interfaces that accept 100M, 1G or 10G modules. If the design calls for fewer fibre ports or for integrated RJ-45 connectivity, a different model is required.

Questions about this item

What does the SFP+ interface cap the 24 ports at in practice?

Each SFP+ port runs at 100 Mb, 1 Gb or 10 Gb depending on the transceiver you fit, so the practical ceiling is 10 Gbps per port.

What rack depth and weight must the cabinet accommodate?

The chassis is 442 mm deep and weighs 6.25 kg; with the power supply fitted the depth grows to 449 mm.

How do you initially configure the switch, and what step is often missed?

Connect to the RJ-45 serial console port, run the first-time setup wizard, then save the running configuration — many forget the final save and lose settings after a reboot.
