Frequently asked questions

When is the Cisco ASA5540-K8 end of life?

Cisco announced End-of-Sale for the ASA5540-K8 effective Sep 16, 2013. The Last Date of Support (LDoS) is Sep 30, 2018, after which Cisco no longer provides support. It is past its last date of support.

What replaces the Cisco ASA5540-K8?

Cisco's recommended migration is the Cisco ASA 5545-X (ASA 5500-X Series). 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 ASA5540-K8?

Not from Cisco. The ASA5540-K8 passed its Last Date of Support (Sep 30, 2018), 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.
