Extreme Networks's end-of-life bulletin names Summit X440-24t as the recommended migration path for the Extreme Networks Summit X250e Series. The exact wording and any per-part-number mapping are in the linked bulletin.
Is the Extreme Networks Summit X250e Series end of life?
Extreme Networks support for the Extreme Networks Summit X250e Series ended Dec 2018. Unsupported units need a plan. Full lifecycle dates by part number: https://eosl.ai/system/extreme-summit-x250e-series/.
Is there a per-part-number replacement mapping for the Summit X250e Series?
Yes — the bulletin maps replacements at the part-number level for 16 SKUs (for example 15101 → Summit X440-24t / Summit X440-24t-TAA / Summit X440-48t / Summit X440-48t-TAA / Summit X440-24p / Summit X440-24p-TAA). The full table is on this page.
Do I have to buy the Extreme Networks-recommended replacement?
No. The bulletin's named successor is Extreme Networks's suggested path, not an obligation. Teams also keep Summit X250e Series units running under third-party maintenance after the support cutoff, migrate to a different vendor, or run low-criticality units to failure with the risk documented. See the support-options guide for the trade-offs.
