Juniper EX3400 — Used & Refurbished (Juniper)

Block 1:

How Much Does Juniper EX3400 Cost in 2026?

In 2026, used Juniper EX3400 switches range from $800–$25,000, depending on condition and included modules. Used units (as-is, no testing) start at $800–$3,500. Refurbished models with 1-year warranty cost $5,000–$12,000. Vendor-certified (e.g., Caladan Semi) units with 3-year warranty and full testing run $15,000–$25,000, often including 10G SFP+ transceivers or stacking modules. Compared to Juniper’s 2026 OEM list price (~$18,500 for base model), buyers save up to 85% on used options. Caveat: Units from 2020–2022 may lack updated firmware support for 2026 OS versions, adding $500–$1,500 in upgrade costs.
