Extreme 5520 Switches - Refurbished, Used, and New

Best Selling

Extreme 5520 switches are 1U universal switches for the campus edge and small aggregation layers. Each switch boots either Switch Engine (EXOS) or Fabric Engine (VOSS), so the same hardware fits a traditional stacked closet or an Extreme Fabric Connect network. The fixed models here carry 24 or 48 RJ45 ports at 1G, two 40G QSFP+ ports on the front for stacking or uplinks, and a rear VIM slot that adds four 10G or 25G uplinks. NetworkTigers sells 5520 switches, VIM uplink modules and power supplies refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which 5520 do I need?

Pick the port type first. The W models supply high-power PoE, so choose 5520-24W where the switch feeds Wi-Fi 6 or Wi-Fi 6E access points, PTZ cameras or lighting; choose 5520-48T for desktops, servers and other switches that bring their own power. Next decide how the switch reaches the core. The two front QSFP+ ports give 40G uplinks or stacking in Switch Engine; the rear VIM slot adds four more uplinks, 10G with the 5520-VIM-4X or 25G with the 5520-VIM-4YE. A VIM is sold separately, so confirm whether the listing includes one. Then count power supplies. Each switch has two bays; a data-only switch runs on one XN-ACPWR-800W-F, while a fully loaded PoE switch needs two for the full PoE budget and redundancy. Finally, tell us which operating system you run, Switch Engine or Fabric Engine, so the switch arrives on the matching version.

Frequently asked questions

Can the 5520 stack with a 5420 or 5320?
Stacking in Switch Engine is within the 5520 family. The 5420 and 5320 use their own stacking, so keep each family in its own stack and link them over uplinks.

Do the 40G QSFP+ ports work as regular uplinks?
Yes. When not used for stacking they act as 40G ports and accept QSFP+ optics, QSFP+ direct attach cables, or breakout cables to four 10G links.

Why does the power supply part number end in F?
F marks front-to-back airflow, the standard direction for a switch mounted with its ports facing the cold aisle. Match the airflow of every supply and fan in the same chassis.
