Extreme Networks S-Series modular switch chassis Replacement — What Extreme Networks Recommends
Extreme Networks support for the Extreme Networks S-Series modular switch chassis ended Apr 2024. Unsupported units need a plan. Extreme Networks's own end-of-life bulletin names the successor below — quoted from the source, with the successor's live support status where EOSL.ai tracks it.
The Extreme Networks-named replacement
per-part mapping in the bulletin (3 replacements listed) — named in the Extreme Networks EOL bulletin ↗ as the migration path.
VSP8600 and 8400 families is not yet tracked on EOSL.ai — no vendor end-of-life notice has been captured for it, which is typical of current products.

Migration questions
What is the replacement for the Extreme Networks S-Series modular switch chassis?
Extreme Networks's end-of-life bulletin names VSP8600 and 8400 families as the recommended migration path for the Extreme Networks S-Series modular switch chassis. The exact wording and any per-part-number mapping are in the linked bulletin.
Is the Extreme Networks S-Series modular switch chassis end of life?
Extreme Networks support for the Extreme Networks S-Series modular switch chassis ended Apr 2024. Unsupported units need a plan. Full lifecycle dates by part number: https://eosl.ai/system/extreme-s-series-modular-switch-chassis/.
Is there a per-part-number replacement mapping for the S-Series modular switch chassis?
Yes — the bulletin maps replacements at the part-number level for 10 SKUs (for example S1-CHASSIS-A → VSP8600 and 8400 families / SLX / MLX). 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 S-Series modular switch chassis 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.
