Frequently asked
When is the Dell S4048 end of life?
Dell's published notice sets End-of-Sale for the S4048 at Jan 30, 2022. The published end-of-support date is Jan 29, 2027, after which vendor support ends. Check the milestones on this page and plan the refresh ahead of the support cutoff.
What replaces the Dell S4048?
Dell 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 S4048, with TAA country-of-origin screening on request.
Can I still buy or get support for the S4048?
New units are no longer sold by Dell after the End-of-Sale date; remaining channel stock and refurbished units are the only sources. Vendor support continues until Jan 29, 2027 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.
