Options from here
Unsupported nowThe Extreme Networks Summit X670 Switches is past Extreme Networks end of service life. These are the paths teams take from here:
Keep it in production past the OEM cutoff with an independent maintainer.
Buy spares now, while units still circulate on the secondary market.
It is unsupported today — set a migration timeline and budget.
Low-criticality role — document the risk, harden backups, retire on your terms.
Independent and informational — EOSL.ai sells no hardware or maintenance and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the asset's role.
