Extreme Networks S-Series modular switch chassis — End-of-Life & EOSL Dates

PAST VENDOR SUPPORTExtreme Networks ended support in April 2024.

S-Series modular switch chassis. Extreme Networks end-of-life bulletin "EOS Update for S-Series Modular Switches and SSA (TAA) Switches", read in full; each date below is shown with the bulletin's own wording.

Every tracked Extreme Networks S-Series modular switch chassis SKU group is past Extreme Networks end of service life (last group Apr 2024). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure. Extreme Networks’s named migration path: VSP8600 and 8400 families.
