Extreme Summit X440 Switches - Refurbished, Used, New

Best Selling

Extreme Summit X440 switches are first-generation 1RU access switches for campus and branch closets, running ExtremeXOS with SummitStack-V stacking. The line pairs 24 or 48 Gigabit RJ45 ports, with or without PoE+, with 1G SFP uplinks, and the -10G models add two 10G SFP+ ports for faster uplinks or stacking. NetworkTigers sells X440-24p, X440-24p-10G, X440-48T, X440-48T-10G and X440-48P switches refurbished, used and new. Every unit is tested before it ships so it works when it arrives.

Which Summit X440 do I need?

Decide on PoE first: the p and P models power phones, access points and cameras, the T models are data only. Then decide how the switch connects upstream. The plain X440-24p, X440-48T and X440-48P uplink over 1G SFP ports, which is enough for a small closet feeding a 1G distribution layer. The -10G models trade some 1G SFP ports for two 10G SFP+ ports, and those SFP+ ports do double duty: they can be uplinks, or they can carry SummitStack-V so that several X440 switches run as one stack over standard 10G optics or direct attach cables. The 48T and 48P carry dedicated SummitStack ports instead, which stack over a short stacking cable. Check how many PoE devices you need per closet and their draw before choosing between 24 and 48 ports, and if you are adding to an existing X440 stack, match the stacking method already in use.

Frequently asked questions

Can a first-generation X440 stack with an X440-G2?
No. The X440 and X440-G2 are different hardware generations and stack only within their own generation. Mixed closets run them as separate stacks or as standalone switches.

What are the combo ports on the X440-24p-10G?
Four ports that can be used as either RJ45 copper or 1G SFP fiber, one or the other at a time per port. They give a 24-port switch a few extra copper drops when fiber uplinks are not in use.

Does an X440 need a separate power supply for PoE?
No. The PoE budget comes from the switch's internal power supply. The number of devices it can power at full PoE+ draw depends on the model, so tell us your device count and we will confirm the fit.
