CBS350-24P-4X-EU combines fanless cooling with 24 Gigabit Ethernet PoE+ access ports and four fixed 10G SFP+ uplinks in a rack-mount 1U chassis. This managed Layer 2+ switch belongs to the Cisco Business 350 Series and connects small-office computers, IP phones, wireless access points, and surveillance cameras. Its copper interfaces supply endpoint power, while the built-in fiber uplinks connect to distribution without an additional network card. An internal AC supply keeps the power arrangement within the chassis rather than using an external adapter. The discontinued CBS350-24FP-4X-EU sibling raises available endpoint power to 370W. Selection depends on aggregate endpoint demand, rather than the number of PoE-capable sockets alone.

128 Gbps switching capacity handles access and uplink traffic with nonblocking forwarding. 95.23 Mpps forwarding rate applies to 64-byte packets, providing the packet-processing figure for small-frame traffic. 195W of shared PoE power requires endpoint loads to fit the aggregate allocation. Static routing and RIP v2 support inter-VLAN connectivity, while PBR directs selected traffic toward specified next hops; static routing supports 990 routes and 128 IP interfaces. Management storage comprises 512 MB DRAM and 256 MB flash, with a separate 1.5 MB packet buffer shared across the ports. STP/RSTP/MSTP control switching loops, and LACP groups links for aggregated connections. CBS350-24P-4X-EU supports browser-based configuration, a text-view CLI, SSH, and SNMP, alongside dashboard and mobile-app administration. Eight hardware queues provide traffic prioritization through strict-priority and Weighted Round-Robin scheduling. The Cisco Business switch uses a fixed internal supply without internal power redundancy, so chassis power availability remains a separate consideration from link redundancy.

When an office adds IP phones, wireless access points, or surveillance cameras, endpoint selection must include startup and steady-state power requirements. Time-based PoE can switch endpoint power according to a schedule, so identify devices that must remain energized and specify the required power behavior before the PO.
When extending an existing Business 350 installation, the interconnect plan must distinguish stack links from distribution links. Ring and chain topologies use 10G fiber interfaces, so the intended topology affects connection planning. Specify the topology, interconnect media, and remaining uplink requirements before ordering another member.
When purchasing switches for several small offices, configuration delivery belongs in the staging plan rather than being left to each site. Cisco Network Plug and Play supports provisioning, while text-editable configuration files support reusable settings. Specify the provisioning workflow, site-specific configuration changes, and staging responsibility before the PO.
Native multigigabit copper access
The copper access ports stop at Gigabit Ethernet. C1300-24MGP-4X provides eight 2.5G ports and sixteen Gigabit ports, rather than multigigabit capability across every access port.
Aggregate endpoint power above 195W
The shared endpoint power allocation stops at 195W. C1300-24FP-4X is the current full-PoE alternative, retaining 24 Gigabit access ports and four 10G SFP+ uplinks.
Continuing vendor security maintenance
Software maintenance and vulnerability support ended October 29 2025. C1300-24P-4X is the current replacement for purchases requiring a model beyond the discontinued Business 350 generation.

CBS350-24P-4X-EU identifies the Business 350 series, 24 Gigabit access ports, PoE+ powering, four 10G SFP+ uplinks, and the EU regional variant. EU covers the European Economic Area and additional countries, rather than a software tier. The regional suffix does not change the access-port count, uplink configuration, or shared power allocation.
CBS350-24P-4X-EU supports an HTTP/HTTPS web interface, a CLI through its RJ-45 console or SSH, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. Cisco Network Plug and Play supports provisioning, and a Telnet client is available. HTTPS and SSH provide encrypted access for browser-based and command-line administration.
Yes, CBS350-24P-4X-EU reached end of sale on October 29 2024. Software maintenance and vulnerability support ended October 29 2025, while the last date of hardware support is October 31 2029. C1300-24P-4X is the current replacement, so hardware support availability should not be confused with continuing security maintenance.
ORM Systems offers CBS350-24P-4X-EU new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for refurbished units. Every condition has 30-day returns; terms apply. Cisco's platform warranty is limited lifetime, with service ending October 31 2029. Refurbished units are inspected, bench-tested, firmware verified, and factory-default wiped.
No, the Business 350 switch requires no separate switch license or software subscription to operate its included features. Hardware purchase includes the switch functionality rather than a choice between separately purchased software tiers. Neither a mandatory subscription term nor a network-license upgrade needs to accompany this switch on the PO.
CBS350-24P-4X-EU replaces the discontinued SG350X-24P-K9-EU and SG550X-24P-K9-EU. Their end-of-sale dates were October 30 2021 and July 30 2022, respectively. These are historical migration relationships, not promises of interchangeable configurations or stack compatibility. The current forward replacement for the Business 350 model itself is C1300-24P-4X.
CBS350-24P-4X-EU provides a shared 195W PoE budget across 24 PoE+ access ports. The budget is the aggregate power available to attached endpoints, not a separate allocation for every socket. Size the connected device load against that total, including the power requirements of phones, access points, and cameras that operate together.
Business 350 10G uplinks support SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber. Supported connection options also include SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M copper cables. Specify the connection medium, cable length or fiber reach, and matching remote interface when assembling the uplink accessories for the order.
A Business 350 hardware stack contains a maximum of four supported members, including this 10G-uplink model. Standard 10G fiber interfaces provide the interconnects, with ring or chain topology available. The stack operates as one managed system with a single IP address, rather than merely grouping individually configured switches under one dashboard.
CBS350-24P-4X-EU supports static routing, RIP v2, and PBR, placing the switch in the Layer 2+ category. Static IPv4 routing supports 990 routes and 128 IP interfaces. Routing interfaces can be physical ports, link aggregation interfaces, VLAN interfaces, or loopback interfaces; these capabilities are included without purchasing a higher software tier.
No, CBS350-24P-4X-EU includes its internal AC power supply and accepts 100-240V AC input. The original package also includes a power cord and mounting kit, so a separate supply is not a standard dependency. The chassis is 445 mm wide, 299 mm deep, and 44 mm high for rack installation.
CBS350-24P-4X-EU provides 195W of endpoint power, while CBS350-24FP-4X-EU provides 370W. Both models are discontinued, so the distinction remains useful when identifying installed equipment or specifying matching spares. The 195W configuration suits lower aggregate endpoint demand; the 370W configuration addresses existing Business 350 installations requiring a larger shared power allocation.
CBS350-24P-4X-EU has four 10G SFP+ uplinks, whereas CBS350-24P-4G-EU has four 1G SFP uplinks. Both are discontinued models, making uplink speed an important check for replacement spares. The 10G model matches existing 10G distribution connections; the 1G variant suits installed networks whose uplink interfaces remain at Gigabit Ethernet speed.
CBS350-24P-4X-EU passed its October 29 2024 end-of-sale milestone, while C1300-24P-4X is the current replacement. This is a lifecycle distinction rather than a change in the stated access-port or uplink configuration. The Business 350 model suits existing-estate sparing; C1300-24P-4X addresses purchases that require the current migration model instead.
