Frequently asked questions

When is the Cisco SF550X-48-K9-NA end of life?

Cisco announced End-of-Sale for the SF550X-48-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 SF550X-48-K9-NA?

Cisco's recommended migration is the Cisco SG550X-48 48-Port Gigabit Stackable 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 SF550X-48-K9-NA?

Not from Cisco. The SF550X-48-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.
