CBS350-24XT-UK provides 10 Gigabit copper connectivity in a managed Layer 2+ switch for small-office networks. Twenty dedicated RJ-45 connections sit alongside four fixed copper/SFP+ combo uplinks, with each shared pair allowing one active connection. The full-width 1U chassis belongs to the Cisco Business 350 Series and connects servers, workstations, and other network devices without supplying endpoint power. The discontinued CBS350-24P-4X-UK differs by providing PoE+ for Gigabit endpoints. Data interfaces also support 1G operation, allowing lower-speed connections within the same configuration. A separate Gigabit out-of-band management port provides an administrative connection apart from the data interfaces, while the RJ-45 console supports local configuration access.

480 Gbps switching capacity defines the aggregate switching bandwidth available for traffic planning. 240 Mpps forwarding sets the published packet-processing rate for 64-byte packets. Static routing and RIP v2 handle IPv4 routing, while PBR selects next hops using IPv4 or IPv6 access rules; the routing limits are 990 static routes and 128 IP interfaces. 124.5W worst-case consumption at 220V provides the upper input figure for electrical sizing. CBS350-24XT-UK carries 512 MB of DRAM and 256 MB of flash for operating memory and image storage. A 3 MB packet buffer is dynamically shared across the ports rather than assigned as a fixed amount to each interface. STP/RSTP/MSTP address switching loops, and LACP supports aggregated connections. The MAC table accommodates 16000 addresses, while 4094 simultaneous VLANs provide the segmentation ceiling. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection support access controls based on trusted addressing information.
CBS350-24XT-UK is offered new sealed or certified refurbished; ORM warranties are up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, while Cisco's limited lifetime hardware warranty ends October 31, 2029. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, PSU status, and fan status, with firmware verified and configurations wiped to factory default. Specify condition, quantities, and regional power cords on the accepted PO; every condition has 30-day returns, terms apply. Government orders qualify for Net-30, and enterprise or volume orders have UK, EU, US, and MEA stock/RMA service with advance replacement.

When replacing an installed SX350X-24-K9-UK or SX550X-24-K9-UK, use the exact regional replacement identity rather than assuming any Business 350 model is equivalent. Both older copper switches have this configuration as their replacement. Specify the required condition and reconcile existing connection assignments before issuing the purchase order.
When multiple locations require centrally staged configurations, Business 350 supports Cisco Network Plug and Play and SCP file download. CLI privilege levels 1, 7, and 15 separate administrative access. Specify the provisioning method, configuration file handling, and administrator privileges before the purchase order so the staging requirements accompany the hardware order.
When a lab or staging purchase includes traffic-capture acceptance testing, Business 350 port mirroring can send traffic from eight source ports to one destination port. RSPAN also supports a remote analysis destination across a Layer 2 domain. Identify source interfaces and specify the capture connection before the PO.
PoE-powered phones or access points
CBS350-24XT-UK provides no endpoint power. C1300-24P-4X is the PoE migration option for the discontinued Gigabit model, but its access connections are Gigabit rather than 10 Gigabit.
Copper connections plus dedicated fiber uplinks
Four SFP+ interfaces share copper connections, so fiber links reduce available copper connections. CBS350-48XT-4X-UK has dedicated uplinks but is discontinued, with no current migration model.
Continuing Cisco security software updates
CBS350-24XT-UK reached the end of vulnerability/security support on October 29, 2025. C1300-24XT is its replacement, retaining the 24-port copper configuration with four shared SFP+ interfaces.

CBS350-24XT-UK identifies a Cisco Business 350 managed switch: CBS350 is the series, 24 is the logical data-port count, and XT identifies the 10 Gigabit copper configuration with four shared SFP+ interfaces. UK is the regional suffix for the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia.
CBS350-24XT-UK supports an HTTP/HTTPS web UI, Textview CLI over SSH or the RJ-45 console, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP. An embedded Dashboard probe supports centralized administration, Cisco Network Plug and Play handles provisioning, and a separate 1G port provides out-of-band management. Telnet client functionality is included.
No, CBS350-24XT-UK does not supply PoE to endpoints; the chassis uses an internal AC supply. Its 24 logical data connections carry network traffic without providing endpoint power. Specify independently powered devices or separate endpoint power arrangements rather than treating the copper interfaces as powered connections for phones or access points.
CBS350-24XT-UK provides four 10G SFP+ interfaces shared with four copper connections, not four additional data ports. Each shared pair allows one active medium. SFP-10G-SR supports multimode fiber, and SFP-10G-LR supports single-mode fiber. Specify the optic and remote link media together with the chosen copper or fiber connection.
Business 350 hardware stacking supports four members, and CBS350-24XT-UK is a stackable model. Stack interconnects use 10G fiber interfaces, with ring or chain connections and active/standby control. Cross-stack link aggregation is supported. Specify the interconnect media, physical topology, and required member count when assembling the stack order.
Business 350 supports static IPv4 routing, RIP v2, and PBR, with limits of 990 static routes and 128 IP interfaces. Routed interfaces can use physical ports, LAGs, VLAN interfaces, or loopbacks. PBR directs traffic using IPv4 or IPv6 access rules. Size the interface and static-route inventories before assigning a routing role.
CBS350-24XT-UK replaces SX350X-24-K9-UK and SX550X-24-K9-UK, both discontinued 24-port 10GBASE-T stackable models whose end-of-sale date was July 30, 2022. An upgrade order should identify which older unit is being removed and specify the regional replacement and condition, rather than substituting another configuration solely because the series matches.
CBS350-24XT-UK is discontinued, with an end-of-sale date of October 29, 2024. Software maintenance and vulnerability/security support ended October 29, 2025. Applicable service under active contracts or warranty terms ends October 31, 2029. C1300-24XT is the replacement for buyers moving beyond the discontinued Business 350 configuration.
ORM Systems offers CBS350-24XT-UK 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. Every condition has 30-day returns, terms apply. Cisco's limited lifetime hardware warranty is bounded by October 31, 2029, its last support date.
CBS350-24P-4X-UK supplies PoE+ on 24 Gigabit access ports, while CBS350-24XT-UK supplies no endpoint power on its 10 Gigabit connections. Both models are discontinued. The former serves powered Gigabit endpoint requirements; the latter serves independently powered connections requiring the copper speed of the 10 Gigabit configuration.
CBS350-48XT-4X-UK carries 48 copper data ports, compared with the 24 logical data ports of CBS350-24XT-UK. Both models are discontinued, and the 48-port model has no current migration product. The smaller configuration suits lower-density legacy replacement orders; the larger configuration addresses higher copper density where discontinued hardware is acceptable.
C1300-24XT replaces CBS350-24XT-UK, whose end-of-sale date was October 29, 2024. Both configurations provide 24 logical 10 Gigabit copper connections with four shared SFP+ interfaces. The discontinued model serves exact legacy replacement requirements, while C1300-24XT is the migration choice for buyers moving to the replacement series.
