CBS350-24XS-UK concentrates 10 Gigabit fiber connections in a managed Layer 2+ switch for small-business aggregation. The fixed interface arrangement provides 20 dedicated SFP+ connections and four copper/SFP+ combo connections; selecting copper on a combo interface makes its paired SFP+ connection unavailable. The Cisco Business 350 chassis occupies a rack-mount 1U position, and its copper interfaces carry data without PoE output. A separate Gigabit out-of-band management connection provides an administration interface apart from production-facing connections. The discontinued CBS350-24XT-UK reverses the media emphasis with 24 copper 10G interfaces and four shared SFP+ connections. For installations retaining optical links between switches, servers, or storage, the fiber-focused configuration determines which connections can terminate directly at the chassis.

480 Gbps switching capacity provides the switching fabric for aggregating connected links, while 240 Mpps forwarding is specified for 64-byte packets. Static routing, RIP v2, and PBR provide local routed forwarding and next-hop selection for inter-VLAN communication. STP, RSTP, and MSTP control Layer 2 loops, while LACP combines eligible connections into logical links. CBS350-24XS-UK carries 512 MB of DRAM and 256 MB of flash, separating running-system memory from image storage. Shared packet buffering provides 3 MB across the interfaces rather than a dedicated allocation per connection. VLAN separation supports 4094 simultaneously configured VLANs. Four fans provide active cooling, so the chassis is not fanless. The 39W maximum draw supplies the equipment allowance for power planning without an endpoint-power allocation. Browser-based administration and a scriptable CLI provide local configuration paths alongside centralized management. Configuration review should cover loop prevention, link aggregation, and routed interface assignments before the production configuration is committed.
Order CBS350-24XS-UK new sealed or certified refurbished, specifying condition, quantity, and required connection accessories on the PO. Certified refurbished units are inspected and bench-tested, including optics bay recognition, with firmware verified and configuration wiped to factory default. ORM warranty is up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units; returns are 30 days on every condition, terms apply, while Cisco's separate Limited Lifetime coverage ends May 31, 2029. Enterprise and volume purchasing supports PO acceptance, Net-30 for government, and RMA with advance replacement across UK, EU, US, and MEA regional stock/RMA operations.

Replacement PID | C1300-24XS |
Replacing an installed SX350X-24F-K9-UK or SX550X-24F-K9-UK starts with a link inventory, not a like-for-like port label. Both older models reached end of sale on July 30, 2022. Record existing fiber runs, peer interfaces, and required accessories before specifying the replacement purchase order.
When inter-VLAN traffic is moving off a separate router, the configuration needs an interface inventory before hardware is approved. The switch supports 128 IP interfaces, including routed physical ports, link aggregation groups, VLAN interfaces, and loopbacks. Specify the required interface assignments and upstream routing handoff before submitting the purchase order.
When a rollout places equipment near occupied work areas rather than in an isolated equipment room, acoustic planning becomes part of acceptance. Acoustic output is 43 dB at 25°C, so a silent installation is not an appropriate assumption. Confirm placement and site acceptance requirements before submitting the purchase order.
Ongoing scheduled vulnerability maintenance
Scheduled vulnerability support ended May 30, 2025, despite hardware support continuing to May 31, 2029. C1300-24XS is the current migration model.
Twenty-eight simultaneous data connections
Four copper connections share their interfaces with four SFP+ cages, so 28 simultaneous data links are unavailable. The chassis provides 24 usable data interfaces.
Endpoint power over Ethernet
CBS350-24XS-UK is non-PoE, so copper data connections cannot deliver power to phones, cameras, or wireless access points requiring Ethernet power.

CBS350-24XS-UK identifies a Cisco Business 350 switch with 24 10G SFP+ interfaces and a regional UK ordering suffix. CBS350 names the series, 24 gives the interface count, and XS denotes the SFP+ configuration; UK also covers Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia.
CBS350-24XS-UK supports a web UI over HTTP/HTTPS, CLI over console, SSH or Telnet, SNMP, and Cisco Business Dashboard. Cisco Business Mobile for Android requires switch firmware 3.1.1.7 or later; the iOS app cannot install or configure this model. Specify the intended management method and firmware before ordering.
Yes, CBS350-24XS-UK reached end of sale on May 30, 2024, and its last date of support is May 31, 2029. Software maintenance and scheduled vulnerability support ended May 30, 2025. Hardware support remains subject to entitlement until the final support date; C1300-24XS is the current migration model.
No separate license or subscription is required to operate CBS350-24XS-UK, and all switch features are included with the hardware purchase. There are no network-license tiers or minimum subscription terms to select. Specify the hardware condition and required accessories instead of adding a software-tier suffix to the order.
No, CBS350-24XS-UK does not supply PoE power on its copper interfaces. Phones, cameras, and wireless access points using those connections need their own power source or a separate PoE device. Select the endpoint power arrangement independently of the switch's copper or fiber data connections.
CBS350-24XS-UK accepts SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber, plus SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M direct-attach cables. Select each connection by fiber type, distance, and peer interface. Include the exact transceiver or cable PID for every required link on the purchase order.
Cisco Business 350 hardware stacking supports four members, and CBS350-24XS-UK is stack-capable. Each member needs at least two 10G ports assigned to stacking, and all members must run matching firmware. SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M provide supported copper connections; legacy switches cannot join this stack.
Cisco Business 350 supports static IPv4 routing, RIP v2, and PBR, with limits of 990 static routes and 128 IP interfaces. These capabilities provide inter-VLAN forwarding and policy-based next-hop selection. Inventory the intended routes and interfaces before treating the switch as a replacement for a dedicated router.
CBS350-24XS-UK replaces SX350X-24F-K9-UK and SX550X-24F-K9-UK, both discontinued with end-of-sale dates of July 30, 2022. Replacement status does not make the older switches eligible stack partners. Preserve the existing link inventory, then verify connections, firmware, and required accessories before approving an order for replacement hardware.
CBS350-24XS-UK provides 24 SFP+ interfaces, while CBS350-24XT-UK provides 24 copper 10G interfaces with four shared SFP+ connections. Both models are discontinued. The fiber-focused model suits existing optical connections; the copper-focused model suits installations retaining twisted-pair 10G links. Shared connections do not add four independent data interfaces.
CBS350-24XS-UK offers 24 SFP+ interfaces, whereas CBS350-12XS-UK offers 12, including two shared copper connections. Both models are discontinued. The larger switch addresses existing installations needing more optical terminations in one chassis; the smaller model addresses lower-density replacement requirements. Select the density from the required connection inventory.
C1300-24XS is the current migration model for discontinued CBS350-24XS-UK, retaining a 24-port SFP+ configuration with four shared copper connections. The older model serves existing-hardware replacement requirements; the current Catalyst 1300 model is the migration choice when purchasing beyond the older switch's sales and software-maintenance milestones.
CBS350-24XS-UK is available new sealed or certified refurbished from ORM Systems. ORM warranty is up to 3-year extended for new units or up to 1 year refurbished; returns are 30 days on every condition, terms apply. Cisco's Limited Lifetime coverage includes next-business-day replacement where available and ends May 31, 2029.
