Frequently asked questions
When is the Cisco WS-C4900M end of life?
Cisco announced End-of-Sale for the WS-C4900M effective Oct 30, 2016. The Last Date of Support (LDoS) is Oct 5, 2021, after which Cisco no longer provides support. It is past its last date of support.
What replaces the Cisco WS-C4900M?
Cisco's recommended migration is the Cisco Nexus 9300 (N9K-C93180YC-FX3). 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 WS-C4900M?
Not from Cisco. The WS-C4900M passed its Last Date of Support (Oct 5, 2021), 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.
