Frequently asked questions
When is the Cisco C6840-X-LE-40G end of life?
Cisco announced End-of-Sale for the C6840-X-LE-40G effective Oct 30, 2020. The Last Date of Support (LDoS) is Oct 31, 2025, after which Cisco no longer provides support. It is past its last date of support.
What replaces the Cisco C6840-X-LE-40G?
Cisco's recommended migration is the Cisco Catalyst 9500 Series 48-Port 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 C6840-X-LE-40G?
Not from Cisco. The C6840-X-LE-40G passed its Last Date of Support (Oct 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.
