SG550X-24P-K9 is a managed Gigabit PoE+ access switch with 24 powered access ports and four fixed 10G uplinks. Two uplinks are dedicated SFP+ connections; two are shared copper/SFP+ combo connections. The rack-mount Cisco 550X Series supports hardware stacking for existing small-business networks. The discontinued SG550X-24MP-K9 provides a larger power allocation for the same access-port count.
SG550X-24P-K9 price for new stock is $1,932.00. SG550X-24P-K9 refurb price is $2,151.38. SG550X-24P-K9 is in stock and available for next-day dispatch. (terms applied)

SG550X-24P-K9 is available new sealed or certified refurbished, with ORM extended warranty coverage of up to 3 years for new units and up to 1 year for certified refurbished units; every condition includes 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested, including power-on and POST, rated-speed port links, PoE output under load on every powered port, clean boot, firmware verification and configuration wiping to factory default.

When replacing SF550X-24P equipment, distinguish a like-family replacement from a new-generation purchase. The North American predecessor reached end of sale on June 18, 2020. Preserve the existing configuration requirements, identify the destination region, and specify the exact hardware identity before issuing the purchase order.
When an existing installation needs replacement stock across several territories, align the spare order with the receiving location and RMA process. ORM Systems supports regional stock and RMA handling across four regions: UK, EU, US and MEA. Specify the destination, condition and advance-replacement requirement before the purchase order.
10G Ethernet on every access port
The access connections are Gigabit Ethernet, not native 10G Ethernet. The four uplink connections do not provide 10G capability across the access-port bank.
Cisco support beyond July 2027
Cisco support ends July 31, 2027. C1300-24P-4X is the current migration endpoint; the intermediate CBS350-24P-4X-NA replacement is also discontinued.

SG550X identifies the Gigabit 550X range; 24P identifies 24 powered ports. SG550X-24P-K9-NA is the North American regional ordering form.
SG550X-24P-K9 supports HTTP/HTTPS, console, SSH/Telnet CLI, SNMP, Smart Network Application, FindIT Network Manager and Active Advisor.
SG550X-24P-K9 is discontinued, with end of sale on July 30, 2022. Its software-maintenance milestone passed on July 30, 2023.
ORM Systems offers SG550X-24P-K9 new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Both conditions have 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty is subject to eligibility and the July 31, 2027 support boundary.
SG550X-24P-K9 regional forms replaced discontinued SF550X-24P-K9-CN, SF550X-24P-K9-EU, SF550X-24P-K9-NA and SF550X-24P-K9-UK equipment. These predecessors used 10/100 access connections.
SG550X-24P-K9 allocates 195W to PoE, versus 382W for SG550X-24MP-K9. Both are discontinued; the distinction matters when matching existing powered-endpoint loads.
SG550X-24P-K9 has 24 access ports; SG550X-48P-K9 has 48. Both are discontinued. Existing installations requiring more physical endpoint connections distinguish the higher-density model.
SG550X-24P-K9 combines two dedicated SFP+ uplinks with two copper/SFP+ combo uplinks; C1300-24P-4X has four SFP+ uplinks. The former matches legacy hardware; the latter is the current migration endpoint.
C1300-24P-4X is the current migration endpoint for the Cisco SG550X-24P. The original North American replacement, CBS350-24P-4X-NA, subsequently reached end of sale on October 29, 2024.
SG550X-24P-K9 reaches its last date of Cisco support on July 31, 2027, subject to applicable entitlement. Purchasing remaining inventory does not restart that lifecycle deadline.
