Frequently asked questions
When is the Cisco SG550XG-8F8T-K9-NA end of life?
Cisco announced End-of-Sale for the SG550XG-8F8T-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-8F8T-K9-NA?
Cisco's recommended migration is the Cisco SX550X-16FT 16-Port 10G 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-8F8T-K9-NA?
Not from Cisco. The SG550XG-8F8T-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.
