Cisco's bulletin names the CBS250-48P-4G as the recommended replacement, keeping the same PoE-on-48-port profile under the Cisco Business brand.

Frequently asked questions
When is the Cisco SG250-50P-K9-NA end of life?
Cisco announced End-of-Sale for the SG250-50P-K9-NA effective Oct 30, 2021. The Last Date of Support (LDoS) is Oct 31, 2026, after which Cisco no longer provides support. It is past its last date of support.
What replaces the Cisco SG250-50P-K9-NA?
Cisco's recommended migration is the Cisco Business 250 Series Smart Switch (CBS250-48P-4G). 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 SG250-50P-K9-NA?
Not from Cisco. The SG250-50P-K9-NA passed its Last Date of Support (Oct 31, 2026), 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.
