Frequently asked
When is the Juniper EX4300-48P end of life?
Juniper's published notice sets End-of-Sale for the EX4300-48P at Mar 31, 2024. The published end-of-support date is Mar 31, 2029, after which vendor support ends. Check the milestones on this page and plan the refresh ahead of the support cutoff.
What replaces the Juniper EX4300-48P?
Juniper has not named a one-for-one replacement in the notice this page is built from. Uniqcli can recommend and quote the current equivalent for the EX4300-48P, with TAA country-of-origin screening on request.
Can I still buy or get support for the EX4300-48P?
New units are no longer sold by Juniper after the End-of-Sale date; remaining channel stock and refurbished units are the only sources. Vendor support continues until Mar 31, 2029 under an active support contract. For a fleet still running this hardware, the practical next step is a refresh plan — request a quote and we will price the current replacement.
Send unit counts or a bill of materials — we price the current replacement, confirm stock and TAA country of origin, and return one reviewed refresh quote.
