Cisco Catalyst 3650 Series End-of-Life & EOSL Dates

The Catalyst 3650 is a standalone and stackable access switch on the same UADP silicon as the 3850, in 24- and 48-port Gigabit and Multigigabit models with PoE+ and 60W UPOE, plus shallow-depth mini models for cramped cabinets. Uplinks are fixed at purchase, in five configurations from four 1G ports to dual 40G QSFP+, and an optional StackWise-160 module joins up to nine switches into a 160 Gbps stack.

Like its larger sibling it converges wired and wireless access: a switch or stack terminates up to 40 Gbps of wireless traffic as an integrated controller for up to 50 access points and 1,000 clients, running one universal IOS image across license levels with dual field-replaceable power supplies.

The Cisco Catalyst 3650 Series is a switch in Cisco's Catalyst product line. End-of-sale and end-of-service-life dates are listed by part number below, each linked to the Cisco EOL bulletin.

Cisco Catalyst 3650 Series has mixed lifecycle status. Some SKU groups are already past Cisco end of service while others run until May 2028. Confirm the exact part number before any support or refresh decision. For past-EOSL units, weigh third-party maintenance, spares, replacement, or a documented run-to-failure. Cisco’s named migration path: Cisco Catalyst 9300L Series / 9 successor part numbers.
