Cisco Catalyst 4900M Series — End-of-Life & EOSL Dates
The Cisco Catalyst 4900M Series is a switch line. End-of-sale and end-of-service-life dates are listed by part number below, each linked to the Cisco EOL bulletin.
Every tracked Cisco Catalyst 4900M Series SKU group is past Cisco end of service life (last group Oct 2021). Units in production should be treated as unsupported. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure.

Options from here
The Cisco Catalyst 4900M Series is past Cisco 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 and no maintenance, and lists no paid placements. Third-party maintenance keeps unsupported gear in production past the OEM cutoff; whether it fits depends on the role the asset plays.
