CBS350-24S-4G-UK is a fanless, managed Layer 2+ fiber switch with 24 Gigabit SFP access ports and four fixed Gigabit uplinks in a rack-mount 1U chassis. Two uplinks are dedicated SFP ports; the other two share copper and SFP connections, with one medium active per combo port. The Cisco Business 350 serves small-business networks connecting independently powered equipment over fiber rather than supplying power to copper endpoints. The discontinued CBS350-8S-E-2G-UK uses an external power adapter, while this model keeps its supply inside the chassis. This 24-port Gigabit SFP switch belongs on a fiber-port schedule, with the two copper connections reserved for their shared uplink roles.

56 Gbps switching capacity supports wire-speed, nonblocking operation across the installed interfaces. 41.66 Mpps forwarding describes packet handling with 64-byte packets, separating small-packet performance from aggregate bandwidth. Static IPv4 routing accommodates 990 routes, while RIP v2 provides dynamic routing and PBR directs traffic using access-control criteria. Hardware stacking is not supported, so additional units retain independent control planes. CBS350-24S-4G-UK combines 512 MB DRAM with 256 MB flash for its embedded switching software and configuration storage. A 1.5 MB packet buffer is dynamically shared across ports rather than reserved equally for each connection. The address table accommodates 16000 MAC entries, and STP/RSTP/MSTP provides spanning-tree control for redundant Layer 2 paths. Browser administration supports HTTP/HTTPS, while Cisco Business Dashboard, the Cisco Business mobile app and SNMP provide additional administration paths. Dual software images support firmware maintenance without depending on a single stored image.
Choose new sealed or certified refurbished CBS350-24S-4G-UK; refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, optics bay recognition, PSU status and clean boot, with firmware verified and configuration wiped to factory default. Specify condition, quantity and required optical components on the purchase order; ORM accepts POs and offers Net-30 for government. ORM provides up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units and 30-day returns for every condition, terms apply. For enterprise and volume orders, specify regional stock/RMA handling across the UK, EU, US or MEA, with RMA advance replacement.

Lifecycle Status | End of sale May 30, 2024 |
When replacing a discontinued SG350-28SFP-K9-UK, this model is its designated migration option; the older switch reached end of sale on July 30, 2022. Treat the purchase as a hardware refresh rather than assuming an unchanged configuration. Review the existing configuration, fiber connections and required accessories before specifying the replacement order.
When several sites need a common configuration workflow, Textview CLI supports scripting with privilege levels 1, 7 and 15, while SCP supports protected configuration-file downloads. Editable configuration files can be transferred between switches. Define administrator privileges, site-specific settings and the configuration transfer method before placing a multi-unit purchase order.
When a staging bench must reproduce a traffic-analysis setup, port mirroring can send traffic from eight source ports to one destination port. An sFlow agent also exports samples to an external collector. Specify the analyzer connection, collector availability and required mirror sources before ordering equipment for the test environment.
10G fiber connections to distribution
CBS350-24S-4G-UK limits uplinks to 1G. C1300-24XS provides 24 SFP+ ports with four shared 10GE connections, changing the access-port speed as well as the connection options.
Hardware stacking under one control plane
CBS350-24S-4G-UK does not support hardware stacking. Separate switches retain their own control planes; centralized dashboard administration does not turn these units into a single hardware stack.
PoE output for connected endpoints
CBS350-24S-4G-UK provides no PoE output through its copper combo interfaces. Powered endpoints require an independently specified power source rather than receiving operating power from this switch.

CBS350-24S-4G-UK combines CBS350 for Cisco Business 350, 24S for 24 Gigabit SFP ports, 4G for four Gigabit uplinks and UK for its regional ordering suffix. The UK suffix covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia; it is not a software license tier.
CBS350-24S-4G-UK supports an HTTP/HTTPS web interface, Textview CLI through console or SSH, Cisco Business Dashboard, the Cisco Business mobile app and SNMP versions 1, 2c and 3. The Dashboard probe runs on the switch, while the CLI supports scripting and multiple administrator privilege levels for configuration workflows.
CBS350-24S-4G-UK reached end of sale on May 30, 2024, and its last date of support is May 31, 2029. Software maintenance and vulnerability/security support ended on May 30, 2025. No designated migration product is available, so the remaining hardware support period does not include continuing software fixes.
ORM Systems offers CBS350-24S-4G-UK new sealed or certified refurbished. ORM provides up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units; 30-day returns apply to every condition, terms apply. Cisco's eligible limited lifetime warranty includes next-business-day advance replacement where available and ends May 31, 2029.
CBS350-24S-4G-UK replaces the discontinued SG350-28SFP-K9-UK, which reached end of sale on July 30, 2022. The older model's last date of support is July 31, 2027. The replacement is also discontinued, with its own support boundary on May 31, 2029, so neither model represents an ongoing software-maintenance path.
CBS350-24S-4G-UK provides 24 Gigabit SFP access ports and four Gigabit uplinks: two dedicated SFP connections and two copper/SFP combo connections. Each combo connection permits only one active medium at a time. The two RJ-45 network interfaces are shared uplinks, not additional dedicated copper access ports.
CBS350-24S-4G-UK supports MGBSX1 for multimode fiber connections to 500 m and MGBLX1 for single-mode fiber connections to 10 km. These transceivers are separate order items rather than removable uplink cards. Match the selected optic to the fiber installation, remote interface and required distance before specifying the optical components.
CBS350-24S-4G-UK supports static IPv4 routing, RIP v2 and PBR, with 990 static routes and 128 IP interfaces. IPv6 routing is also supported. Layer 3 interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopback interfaces, allowing the routing configuration to follow the required network segmentation.
CBS350-24S-4G-UK cannot form a hardware stack, even though other Business 350 models support stacking. Multiple units remain independently controlled switches rather than members of one forwarding system. Cisco Business Dashboard can administer multiple devices, but that management arrangement does not add hardware stacking capability to this model.
CBS350-24S-4G-UK uses an internal universal AC supply accepting 100-240V AC, without a redundant PSU option. Maximum consumption is 32W at 110V or 34.3W at 220V. The electrical requirement powers the switch itself; this non-PoE model does not allocate part of that input power to connected endpoints.
195W of PoE+ power distinguishes the discontinued CBS350-24P-4G-UK from CBS350-24S-4G-UK, which supplies no PoE. The powered model uses copper access connections rather than SFP access connections. Among existing-stock purchases, the powered configuration suits endpoint-power requirements; the SFP configuration suits buyers retaining a Gigabit fiber network.
An internal AC supply distinguishes CBS350-24S-4G-UK from the discontinued CBS350-8S-E-2G-UK, which uses an external power adapter. The smaller model also has eight primary SFP ports rather than 24. Existing-stock buyers needing fewer fiber connections can consider the smaller configuration; internally powered rack installations favor the larger chassis.
10G SFP+ connections distinguish the discontinued CBS350-24XS-UK from Gigabit-only CBS350-24S-4G-UK. The higher-speed configuration suits existing 10G fiber deployments, while the Gigabit configuration suits retained 1G links. C1300-24XS is the migration model for the discontinued 10G unit, not a designated replacement for the Gigabit unit.
