Cisco SG300-52MP 52-Port Gigabit Max-PoE Managed Switch
Past Last Date of Support (Oct 31, 2023)The SG300-52MP was the Max-PoE, 52-port member of Cisco's original 300 Series managed switch line, sized to power dense wireless and IP phone deployments. Cisco's bulletin names the SG350-52MP as the direct replacement, and Uniqcli, an authorized Cisco partner, can quote a current Cisco Business Max-PoE switch at this port count and help plan the cutover.

Frequently asked questions
When is the Cisco SG300-52MP-K9-NA end of life?
Cisco announced End-of-Sale for the SG300-52MP-K9-NA effective Oct 4, 2018. The Last Date of Support (LDoS) is Oct 31, 2023, after which Cisco no longer provides support. It is past its last date of support.
What replaces the Cisco SG300-52MP-K9-NA?
Cisco's recommended migration is the Cisco SG350-52MP 52-Port Gigabit Max-PoE Managed 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 SG300-52MP-K9-NA?
Not from Cisco. The SG300-52MP-K9-NA passed its Last Date of Support (Oct 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.
