Frequently asked questions
When is the Cisco FPR-4140-K9 end of life?
Cisco announced End-of-Sale for the FPR-4140-K9 effective Aug 31, 2020. The Last Date of Support (LDoS) is Aug 31, 2025, after which Cisco no longer provides support. It is past its last date of support.
What replaces the Cisco FPR-4140-K9?
Cisco's recommended migration is the Cisco Firepower 4125 Security Appliance. 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 FPR-4140-K9?
Not from Cisco. The FPR-4140-K9 passed its Last Date of Support (Aug 31, 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.
