CBS350-24P-4X-UK is a fanless, managed Layer 2+ switch with 24 Gigabit Ethernet PoE+ access ports and four fixed 10G SFP+ uplinks. Its full-width 1U chassis serves small-business networks connecting computers, printers, IP phones, wireless access points and surveillance equipment. The uplinks are built in rather than supplied through a removable network card. Within the Cisco Business 350 Series, this configuration combines powered copper access with higher-speed upstream connections without fan cooling. The discontinued CBS350-24FP-4X-UK differs by providing a 370W endpoint power budget. CBS350-24P-4X identifies the underlying hardware model, while the complete regional part number distinguishes the order being placed. Specify the full PID when matching existing equipment rather than relying on the series name alone.

128 Gbps switching capacity supports nonblocking forwarding across the installed interfaces. 95.23 Mpps forwarding at 64-byte packet size provides the packet-processing figure for small-packet traffic planning. 195W of shared PoE power requires endpoint demand to be allocated across the powered ports rather than treating every connection as an independent power allowance. Static routing, RIP v2 and PBR provide local routing options, with 990 static routes and 128 IP interfaces setting configuration limits. CBS350-24P-4X-UK has 512 MB DRAM and 256 MB flash for its embedded software and configuration storage. A dynamically shared 1.5 MB packet buffer serves all ports. LACP supports aggregated links, while STP, RSTP and MSTP provide spanning-tree controls. Hardware stacking uses 10G interfaces and supports ring or chain arrangements; stacking links must therefore be accounted for when planning interface assignments.
Specify CBS350-24P-4X-UK in new sealed or certified refurbished condition, and place the selected condition and quantity on the purchase order. Certified refurbished units are inspected and bench-tested for power-on, POST, rated-speed port links and clean boot; PoE output is verified under load on every powered port, firmware is verified, and configuration is wiped to factory default. ORM's new-unit warranty is up to a 3-year extended term, certified refurbished coverage is up to 1 year, and every condition includes 30-day returns with terms applying. For enterprise and volume orders, specify regional requirements: PO accepted, Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US and MEA.

When replacing discontinued SG350X-24P-K9-UK or SG550X-24P-K9-UK units, the migration route passes through CBS350-24P-4X-UK. The older switches reached end of sale on October 30, 2021 and July 30, 2022 respectively. Match the installed configuration and specify whether the PO covers like-for-like sparing or a wider refresh.
When standardizing configuration across separately managed sites, text-editable configuration files and SCP transfer support a common staging workflow. CLI privilege levels 1, 7 and 15 allow access roles to be specified independently of the site template. Include the approved configuration, administrator access requirements and staging checks with the hardware PO.
For a branch rollout spanning the United Kingdom, Saudi Arabia, Qatar or Singapore, the UK regional suffix identifies an ordering variant shared by these destinations. Regional order identification is separate from endpoint configuration. Confirm the installation destination and supplied power cord for each shipment before finalizing the PO.
Security maintenance after October 2025
CBS350-24P-4X-UK reached the end of vulnerability/security support on October 29, 2025. For a maintained replacement purchase, specify the current migration model, C1300-24P-4X.
More than four hardware stack members
CBS350-24P-4X-UK supports a maximum of four hardware stack members. A larger group cannot operate as one supported hardware stack on this model.

CBS350-24P-4X-UK identifies a Cisco Business 350 managed switch: CBS350 is the series, 24 denotes the access-port count, P identifies PoE+, and 4X identifies four 10G SFP+ uplinks. UK is the regional ordering suffix, used for the United Kingdom and several other destinations; it is not a software license tier.
The Cisco Business 350 Series supports a web UI over HTTP/HTTPS, CLI through the console or SSH/Telnet, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. These are alternative management paths rather than separate switch models. Specify the intended administrator access method when preparing the configuration for delivery.
No license or subscription is required to operate Cisco Business 350 Series switches, and all switching features are included with the hardware purchase. There is no mandatory network software tier or minimum subscription term to select. The base hardware PO therefore does not need an additional feature-license line.
CBS350-24P-4X-UK provides a shared 195W PoE budget across 24 PoE+ access ports. The budget is the total endpoint allocation, not an allowance available independently on every port. Add the planned powered-device requirements before ordering, including any phones, wireless access points or cameras that will share that allocation.
CBS350-24P-4X-UK supports SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber in its fixed SFP+ uplinks. SFP-H10GB-CU1M is a supported direct-attach option. Choose the media to match the remote interface and link requirements, and include the selected accessory PID on the purchase order.
Four members are the maximum hardware stack size for supported Cisco Business 350 models, including CBS350-24P-4X-UK. Hardware stacking uses 10G interfaces and supports ring or chain arrangements. Specify the stack topology and interconnect media before ordering, and account for the interfaces assigned to those stack connections.
CBS350-24P-4X-UK supports static routing, RIP v2 and PBR, making its routing classification Layer 2+. Static routing supports 990 routes, with 128 IP interfaces available for configuration. Match the proposed routing design to these capabilities rather than assuming that every routing feature available on enterprise switches is included.
Yes, CBS350-24P-4X-UK reached end of sale on October 29, 2024. Software maintenance and vulnerability/security support ended on October 29, 2025, while the last date of support is October 31, 2029. C1300-24P-4X is the replacement model; remaining hardware purchases should be distinguished from purchases requiring ongoing security maintenance.
CBS350-24P-4X-UK replaces the discontinued SG350X-24P-K9-UK and SG550X-24P-K9-UK. Those models reached end of sale on October 30, 2021 and July 30, 2022 respectively. The migration chain now continues to C1300-24P-4X because the CBS350 model is also discontinued, so distinguish legacy sparing from a current-model refresh.
CBS350-24FP-4X-UK provides a 370W PoE budget, compared with 195W on CBS350-24P-4X-UK. Both models are discontinued. For existing-installation matching, the P model corresponds to the lower shared power allocation, while the FP model corresponds to installations requiring the larger allocation; size the endpoint demand before selecting legacy replacement stock.
CBS350-24P-4X-UK has four 10G SFP+ uplinks, while CBS350-24P-4G-UK has four 1G SFP uplinks. Both are discontinued. The 4X configuration matches existing installations using higher-speed upstream connections; the 4G configuration matches installations retaining Gigabit uplinks. Specify the required uplink speed explicitly when ordering legacy replacement hardware.
CBS350-24P-4X-UK is discontinued, while C1300-24P-4X is its current migration model in the Catalyst 1300 family. The replacement retains the basic 24-port Gigabit PoE configuration with four 10G SFP+ uplinks. The CBS350 model suits legacy matching and sparing; the Catalyst model is the replacement to specify for a new-model refresh.
ORM Systems offers CBS350-24P-4X-UK new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year of warranty. Both conditions include 30-day returns; terms apply. Cisco's Enhanced Limited Lifetime Warranty is separate and subject to Cisco's terms, with Cisco service ending October 31, 2029.
