SG350XG-24F-K9-UK is a managed Layer 2+ fiber aggregation switch with 22 dedicated 10GbE SFP+ ports and two fixed 10G copper/SFP+ combo uplinks. Its non-PoE 1U chassis belongs to the Cisco 350X Series and connects business backbones to servers, storage, and downstream switches. The discontinued SG350X-24P-K9-UK instead provides powered Gigabit copper access. Private VLANs separate isolated endpoints within a shared switching environment, while time-based access control lists restrict traffic according to schedules. Eight hardware queues assign different forwarding treatment to traffic classes during congestion. For storage connections, iSCSI traffic prioritization distinguishes storage flows from other network traffic.

480 Gbps switching capacity supports nonblocking traffic across the physical interfaces. 357.12 Mpps forwarding handles 64-byte packets at wire speed. Static IPv4 and IPv6 routing connects local subnets without dynamic route exchange. SG350XG-24F-K9-UK uses 512 MB of DRAM and 256 MB of flash for management operations and image storage, with a 2 MB packet buffer shared across all ports. The 24-port 10 Gigabit SFP+ stackable managed switch separates administration through a dedicated Gigabit Ethernet management port and an RJ-45 console connection. Administrators can use HTTPS, a scriptable CLI over SSH or Telnet, SNMPv3, Smart Network Application, and FindIT Network Manager for configuration and monitoring. STP/RSTP/MSTP and LACP govern redundant paths and aggregated links, while Dynamic ARP Inspection, IP Source Guard, and DHCP snooping validate source bindings. Authentication can use local accounts, RADIUS, or TACACS+ to control administrative access. 50.4W maximum consumption at 220V AC establishes the upper system load for rack power planning.
ORM Systems offers SG350XG-24F-K9-UK in new sealed and certified refurbished condition; refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, optics bay recognition, PSU status, fan status, and clean boot, with firmware verified and configuration wiped to factory default. Submit the purchase order with the required condition, quantity, and regional power cord. ORM warranties cover new units for up to a 3-year extended term and certified refurbished units for up to 1 year, with 30-day returns on every condition, terms apply; Cisco's original limited lifetime hardware warranty and service ended June 30, 2025.

When consolidating server and storage connections onto a shared aggregation switch, jumbo-frame compatibility becomes a purchase requirement rather than a port-count question. Frame sizes reach 9000 bytes, so confirm the end-to-end MTU across connected equipment and specify matching settings before approving the hardware order.
When several sites need the same initial configuration, the embedded Cisco Network Plug and Play agent provides a provisioning path through PnP Connect. Establish the onboarding workflow and prepare the intended configuration before purchase, then check each site's provisioning requirements before releasing the switch quantities on the PO.
When a lab or staging rack must feed a network analyzer without reconnecting endpoints, port mirroring can copy traffic from eight source ports to one destination port. RSPAN also carries mirrored traffic across a Layer 2 domain. Reserve the analyzer connection and confirm the monitoring scope before ordering.
Current Cisco service eligibility
Cisco service for SG350XG-24F-K9-UK ended June 30, 2025. For a current purchase rather than maintenance of a legacy installation, the forward migration endpoint is C1300-24XS.
Power over Ethernet endpoint supply
SG350XG-24F-K9-UK supplies no PoE power on either copper interface. Endpoints requiring power through the Ethernet cable need a separate power source.
Dynamic routing between network segments
SG350XG-24F-K9-UK supports static IPv4 and IPv6 routes but not dynamic route learning. Networks requiring automatic route exchange cannot use this model as their dynamic routing endpoint.
Four native copper uplink connections
SG350XG-24F-K9-UK has two copper/SFP+ combo connections. C1300-24XS provides four copper/SFP+ combo connections while retaining 24 total switched connections.

SG350XG-24F-K9-UK identifies a 350X family switch with 24 ten-gigabit SFP+ interfaces. SG350XG is the 10G model group; 24F denotes the fiber configuration. UK is the regional suffix for the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia. K9 remains part of the complete ordering identity.
SG350XG-24F-K9-UK supports HTTP/HTTPS browser management, full or menu CLI through the console or SSH/Telnet, and SNMP 1/2c/3. Network-level options include Smart Network Application, Cisco FindIT Network Manager, the embedded FindIT Network Probe, and Active Advisor. Cisco Network Plug and Play supports automated provisioning through PnP Connect.
Yes, SG350XG-24F-K9-UK is discontinued: end of sale was June 18, 2020, and Cisco service ended June 30, 2025. Software maintenance ended June 18, 2021. The direct replacement, SX350X-24F-K9-UK, is also discontinued; migration continues through the discontinued CBS350-24XS-UK to the current C1300-24XS.
ORM Systems offers SG350XG-24F-K9-UK new sealed or certified refurbished, with up to a 3-year extended ORM warranty for new units and up to 1 year for certified refurbished units. Both conditions include 30-day returns, terms apply. Cisco's original limited lifetime hardware warranty and service ended June 30, 2025.
SG350XG-24F-K9-UK has no PoE output, while the discontinued SG350X-24P-K9-UK provides a 195W shared PoE budget. The powered configuration targets phones and access points; the fiber model serves independently powered aggregation equipment. Buyers needing a current powered-access replacement can follow the former model's migration chain to C1300-24P-4X.
SG350XG-48T-K9-UK provides 48 switched 10G connections, compared with 24 on SG350XG-24F-K9-UK. Both models are discontinued and Cisco service has ended. For existing installations, the larger copper-oriented model addresses a higher connection count in one chassis; the smaller fiber-oriented model suits a 24-connection aggregation plan.
C1300-24XS provides four shared 10G copper/SFP+ connections, where the discontinued SG350XG-24F-K9-UK has two. Both have 24 SFP+ interfaces when the shared positions use fiber. SG350XG-24F-K9-UK fits an existing two-combo-port design; C1300-24XS is the current migration choice for buyers needing four shared copper connections.
The Cisco 350X Series stacks four members as one managed system, including compatible SG350X, SG350XG, and SX350X models. Interconnects use 10G fiber or copper network interfaces with ring or chain topologies. SFP-H10GB-CU1M=, SFP-H10GB-CU3M=, and SFP-H10GB-CU5M= provide 1 m, 3 m, and 5 m copper options, respectively.
Yes, SG350XG-24F-K9-UK supports static IPv4 and IPv6 routing between VLANs, but not dynamic routing protocols. IPv4 capacity is 990 static routes and 128 IP interfaces; IPv6 capacity is 245 static routes and 106 interfaces. Inter-VLAN forwarding can remain local, but routes must be maintained statically and matched to the downstream address plan.
The 350X fiber switch supports SFP-10G-SR= and SFP-10G-SR-S= for multimode links, plus SFP-10G-LR= and SFP-10G-LR-S= for single-mode links. SFP-10G-LR= reaches 10 km; SFP-10G-SR= reach depends on the fiber within 26–400 m. Match both link ends and the installed fiber before ordering.
No, SG350XG-24F-K9-UK does not provide PoE output on its copper connections. The switch receives power through its internal AC supply rather than a powered-device network port. Connected endpoints that need electrical power over Ethernet require another power source; the combo interfaces provide network connectivity, not endpoint power.
SG350XG-24F-K9-UK uses an internal universal 100–240V AC power supply, and maximum system consumption is 50.4W at 220V. Consumption at 110V is 49.5W. The fixed supply does not offer an optional internal redundant module, so the purchase plan should match the regional power cord and site AC feed.
Yes, the Cisco SG350XG-24F fits a standard rack as a 1U switch and includes a mounting kit in the original package. The chassis measures 440 mm wide, 44 mm high, and 350 mm deep, weighing 4.16 kg. Verify rack clearance and the quoted mounting hardware before ordering a refurbished unit.
