Juniper EX4300 — Used & Refurbished (Juniper)

Block 1:

How Much Does Juniper EX4300 Cost in 2026?

Used Juniper EX4300 switches in 2026 typically range from $800 to $25,000, depending on condition and configuration. A used, non-functional unit with missing components (e.g., power supplies, SFPs) may fetch $800–$1,500. Refurbished models with basic 10G uplinks and valid base licenses cost $4,000–$8,000. Vendor-certified units with dual power supplies, 40G uplinks, and extended warranties can reach $15,000–$25,000. Savings vs. new OEM list price (currently ~$30,000–$45,000) range from 60% to 85%, but high-end variants with advanced licenses (e.g., Virtual Chassis, QoS) may still require $5,000–$10,000 in additional costs. Caveat: Units with pre-2019 firmware may lack support for modern VLAN scaling (max 4K vs. 16K in 2026).
