Frequently asked questions
When is the Cisco WS-C3850-48T-S end of life?
Cisco announced End-of-Sale for the WS-C3850-48T-S effective Oct 30, 2020. The Last Date of Support (LDoS) is Oct 31, 2025, after which Cisco no longer provides support. It is past its last date of support.
What replaces the Cisco WS-C3850-48T-S?
Cisco's recommended migration is the Cisco Catalyst 9300 48-Port Data, Network Advantage. Uniqcli, an authorized Cisco partner, can quote the replacement TAA-compliant and GPC-payable, and help plan the cutover.
Can I still get support for the WS-C3850-48T-S?
Not from Cisco. The WS-C3850-48T-S passed its Last Date of Support (Oct 31, 2025), so Cisco TAC, hardware replacement, and SmartNet renewals are no longer available. Independent third-party maintenance can still cover the hardware itself, typically well below OEM renewal rates. Uniqcli can review your install base, confirm coverage, and quote extended support or a refresh side by side.
