SG550XG-24F-K9-UK is a managed, fiber-focused 10 Gigabit Ethernet switch with Layer 2+ routing capabilities. Its fixed connections comprise 22 dedicated SFP+ interfaces and two additional SFP+ interfaces shared with 10GBASE-T copper connectors. Each shared pair supports one active connection, rather than simultaneous copper and fiber links. The non-PoE, rack-mount 1U design belongs to the Cisco 550X Series and serves business aggregation, server, and storage connections where endpoint power is supplied separately. A dedicated Gigabit out-of-band management connection separates administrative access from production links. The discontinued SG550XG-24T-K9-UK instead provides dedicated copper connections, distinguishing the legacy copper-focused configuration from this fiber-focused model.

480 Gbps switching capacity accommodates the switch's fixed interfaces, while 357.12 Mpps forwarding performance describes processing of minimum-size packets. Static routing and RIP v2 provide inter-network forwarding; PBR controls next-hop selection, and VRRP supports redundant default gateways. The routing resources accommodate 7168 IPv4 routes and 256 IP interfaces. SG550XG-24F-K9-UK uses 512 MB of memory and 256 MB of flash for its operating software and configuration resources. A dynamically shared 2 MB packet buffer serves traffic across the ports. STP, RSTP, MSTP, and LACP support loop control and aggregated links, while DHCP snooping and Dynamic ARP Inspection address unauthorized address information. Power redundancy requires an external RPS2300 connection rather than a second internal supply.
SG550XG-24F-K9-UK is offered new sealed or certified refurbished; specify condition, quantity, regional power cord, and required interface components on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, optics bay recognition, PSU and fan status, and clean boot, with firmware verified and configuration wiped to factory default. ORM provides up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition, terms apply; Cisco's limited lifetime coverage ended June 30, 2025. For enterprise and volume orders, POs are accepted, Net-30 is available for government, and RMA with advance replacement is available across the UK, EU, US, and MEA.

An existing business switching stack needs another member without introducing a separate management domain. Ring and chain arrangements support different interconnect layouts, while cross-stack link aggregation can span members. Before the purchase order, reserve interfaces for the interconnects and specify the required connection layout and cable lengths.
Several locations need a repeatable configuration rather than individually created settings. Text-editable configuration files, SCP transfers, and Cisco Network Plug and Play support centralized preparation and provisioning. Before ordering, define the configuration template, management addressing, provisioning workflow, and quantity of units requiring the same initial settings.
A staging environment needs to validate segmentation before equipment reaches an existing network. Support for 4094 active VLANs allows the intended VLAN configuration to be exercised alongside security and forwarding settings. Specify the test configuration, peer connections, and required interface media before placing the hardware order.
Ongoing Cisco service and support
Cisco service ended June 30, 2025. C1300-24XS is the current migration endpoint for buyers requiring a supported replacement rather than continued operation of this discontinued model.
Power delivery to connected endpoints
The switch does not supply PoE through its copper connections. Phones, access points, and other powered endpoints require separate power equipment or a different switch.

SG550XG-24F-K9-UK identifies a 550X stackable managed switch with 24 10G SFP+ interfaces, including two shared copper interfaces. The 24F configuration is fiber-focused. The UK regional suffix covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia; retain the complete part number when ordering.
The Cisco 550X Series supports a browser-based HTTP/HTTPS interface, Textview CLI through console or SSH/Telnet, and SNMP management. Additional paths include Smart Network Application, FindIT Network Manager, the embedded FindIT Network Probe, FindIT discovery, Active Advisor, and Cisco Network Plug and Play with PnP Connect.
SG550XG-24F-K9-UK is discontinued: end of sale was June 18, 2020, and Cisco support ended June 30, 2025. Software maintenance ended June 18, 2021. Existing units can continue operating, but an order for remaining hardware does not restart Cisco maintenance or service eligibility.
ORM offers SG550XG-24F-K9-UK new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are available for 30 days on every condition, terms apply. Cisco's original limited lifetime hardware coverage has ended; the last date of Cisco support was June 30, 2025.
SG550XG-24F-K9-UK supports SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber. SFP-10G-LR supports distances to 10 km; SFP-10G-SR reach depends on the installed multimode fiber. Specify the required part number and match both ends of each connection before ordering interface components.
Cisco 550X hardware stacking supports eight members, using standard 10G copper or fiber connections in ring or chain arrangements. SF550X, SG550X, SG550XG, and SX550X models can share a stack. Supported direct-attach options include SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M; reserve connection interfaces when sizing the stack.
SG550XG-24F-K9-UK provides static routing, RIP v2, PBR, and VRRP, with resources for 7168 IPv4 routes and 256 IP interfaces. IPv6 static routing supports 1792 routes. Routing interfaces can be physical ports, aggregated links, VLAN interfaces, or loopback interfaces, so the intended routing design should be checked before deployment.
SG550XG-24F-K9-UK supports external power redundancy through RPS2300 rather than a second internal power supply. Its normal input uses an internal universal AC supply. An external redundancy arrangement therefore requires separate RPS2300 equipment and connection planning; the switch alone does not provide two independent internal supplies.
The Cisco 550X SG550XG-24F is a rack-mount 1U switch measuring 440 mm wide, 44 mm high, and 350 mm deep, with a weight of 4.16 kg. The original package includes mounting hardware. Confirm the required mounting components and cabinet clearance when specifying a replacement unit.
No, SG550XG-24F-K9-UK does not supply PoE to connected devices. Its copper interfaces provide network connectivity rather than endpoint power, and the fiber interfaces cannot deliver electrical power. Include separate endpoint power arrangements when connecting equipment that normally relies on a powered Ethernet connection.
SG550XG-24F-K9-UK has 22 dedicated SFP+ connections where SG550XG-24T-K9-UK has 22 dedicated 10G copper connections. Both configurations are discontinued. The fiber configuration corresponds to existing optical cabling, while the copper configuration corresponds to existing twisted-pair connections; select legacy replacement hardware according to the installed connection media.
SG550XG-24F-K9-UK provides 24 active network connections, whereas SG550XG-8F8T-K9-UK provides 16. Both models are discontinued. The larger configuration corresponds to existing installations needing more connections in one chassis; the smaller configuration corresponds to legacy installations whose required connection count remains within its lower density.
C1300-24XS provides four shared 10G copper connections alongside its SFP+ interfaces, compared with two on SG550XG-24F-K9-UK. C1300-24XS is the current migration endpoint through the discontinued SX550X-24F-K9-UK and CBS350-24XS-UK models. The older switch serves installed-equipment continuity; C1300-24XS serves buyers moving to the current replacement.
