Frequently asked questions

When is the Cisco AIR-CT5508-K9 end of life?

Cisco announced End-of-Sale for the AIR-CT5508-K9 effective May 4, 2018. The Last Date of Support (LDoS) is Jul 31, 2023, after which Cisco no longer provides support. It is past its last date of support.

What replaces the Cisco AIR-CT5508-K9?

Cisco's recommended migration is the Cisco 5520 Wireless Controller. 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 AIR-CT5508-K9?

Not from Cisco. The AIR-CT5508-K9 passed its Last Date of Support (Jul 31, 2023), 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.
