Cisco SG550XG-24T-K9-NA End of Life & End of Support
Cisco SG550XG-24T 24-Port 10GBase-T Stackable Managed Switch
Past Last Date of Support (Jun 30, 2025)The SG550XG-24T was Cisco's 24-port 10GBase-T stackable switch, popular for small business server rooms and aggregation layers that needed 10G copper without an enterprise-class chassis. Cisco's bulletin names the SX550X-24 as the direct replacement, keeping the same 24-port 10GBase-T stacking design. Uniqcli, an authorized Cisco partner, can quote the SX550X-24 and help plan the migration.

Frequently asked questions
When is the Cisco SG550XG-24T-K9-NA end of life?
Cisco announced End-of-Sale for the SG550XG-24T-K9-NA effective Jun 18, 2020. The Last Date of Support (LDoS) is Jun 30, 2025, after which Cisco no longer provides support. It is past its last date of support.
What replaces the Cisco SG550XG-24T-K9-NA?
Cisco's recommended migration is the Cisco SX550X-24 24-Port 10GBase-T Stackable Managed Switch. 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 SG550XG-24T-K9-NA?
Not from Cisco. The SG550XG-24T-K9-NA passed its Last Date of Support (Jun 30, 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.
