Fanless Copper Access With High-Speed Fiber Connections

CBS350-24T-4X-EU combines fanless cooling with managed Layer 2+ access, 24 Gigabit RJ-45 ports, and four fixed 10G SFP+ uplinks in a 1U rack-mount chassis. The Cisco Business 350 series serves small-office networks connecting employee computers, printers, servers, and other wired equipment. Unlike the discontinued CBS350-24P-4X-EU, which supplies a shared 195W PoE+ budget, this model does not deliver power to connected endpoints. Within the Cisco Business portfolio, VLAN segmentation and guest-access controls separate business traffic from other users. The copper access connections and faster fiber uplinks address different network requirements without a removable uplink card or a fan-cooled chassis.

Technical Details

128 Gbps switching capacity supports nonblocking forwarding across the installed interfaces. 95.23 Mpps forwarding performance is specified for 64-byte packets. Static routing and RIP v2 provide routing functions, while PBR directs selected traffic to a configured next hop; the routing resources accommodate 990 static routes and 128 IP interfaces. A dynamically shared 1.5 MB packet buffer serves traffic across all ports. The 512 MB DRAM and 256 MB flash support switch operation and image storage, while the MAC table accommodates 16000 entries for address learning. CBS350-24T-4X-EU provides browser-based configuration, a scriptable CLI, and SNMP for administration and monitoring. LACP supports eight aggregation groups with eight active ports per group, allowing multiple connections to operate as a logical link. STP, RSTP, and MSTP provide spanning-tree controls for switched connections. Energy Efficient Ethernet reduces copper-port consumption during quiet periods, and automatic power shutoff disables inactive links until connectivity returns.

Ordering

ORM Systems supplies CBS350-24T-4X-EU as new sealed or certified refurbished; refurbished units are inspected and bench-tested, with every port linked at rated speed, optics bay recognition checked, firmware verified, and configuration wiped to factory default. New units carry up to a 3-year extended ORM warranty, certified refurbished units up to 1 year, and every condition includes 30-day returns; terms apply. Cisco's Enhanced Limited Lifetime Warranty is separate, and Cisco service ends October 31, 2029. Specify condition, quantity, and accessories on the PO; POs are accepted for enterprise and volume orders, with Net-30 for government and RMA with advance replacement across UK, EU, US, and MEA regions.

Buying Notes

Buying NotesKey Specs

No software subscription required

CBS350-24T-4X-EU requires no feature-license or software-subscription purchase. All switch features accompany the hardware, so an ORM order needs no recurring software term to enable the included functionality.

Maintenance releases have ended

CBS350-24T-4X-EU no longer receives software maintenance releases or planned vulnerability remedies; both milestones passed on October 29, 2025. Account for that maintenance boundary before approving additional deployment.

Specify fiber link components

Fiber connections require compatible transceivers matched to the installed fiber and link distance. Specify SFP-10G-SR for multimode connections or SFP-10G-LR for single-mode connections as separate items on the order.

Best For

Existing Stack Expansion

An existing hardware stack needs another member rather than an independently managed switch. CBS350-24T-4X-EU supports ring and chain topologies, while SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M provide copper interconnect choices. Reserve the interconnect ports and specify the required cable lengths before placing the stack-extension order.

Multi-Site Configuration Standards

A multi-site rollout needs repeatable configuration and centralized monitoring rather than separate manual setup at every location. The embedded Cisco Business Dashboard probe removes the requirement for a separate probe appliance or virtual machine. Confirm the Dashboard arrangement, text-editable configuration files, and provisioning workflow before specifying quantities for each site.

Lab Traffic Analysis

A staging lab needs traffic visibility before an equipment rollout or configuration change. Port mirroring can send traffic from eight source ports to one destination port, and VLAN mirroring provides a separate selection method. Identify the analyzer connection and required source interfaces before ordering the lab switch and associated connectivity.

Not Suitable If

Power delivery to connected endpoints

CBS350-24T-4X-EU provides no PoE output. C1300-24P-4X is the current powered-access alternative with 24 Gigabit ports and four 10G SFP+ uplinks.

Native multigigabit copper access ports

The fixed RJ-45 access interfaces stop at Gigabit Ethernet. The faster SFP+ uplinks do not provide multigigabit copper connections for attached access devices.

Questions & Answers

What does each part of CBS350-24T-4X-EU mean?

CBS350-24T-4X-EU identifies a Business 350 managed switch with 24 non-PoE Gigabit copper ports, four 10G SFP+ uplinks, and a regional ordering suffix. CBS350 names the series, 24 gives the access-port count, T identifies the copper configuration, and 4X identifies the uplinks. EU covers the European Economic Area and other designated countries.

How is the Cisco Business 350 series managed?

The Cisco Business 350 series supports a web UI over HTTP or HTTPS, CLI access through the console, SSH or Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. The browser utility includes simple and advanced modes, while the CLI supports scripted configuration and multiple administrator privilege levels.

Is CBS350-24T-4X-EU discontinued?

Yes, CBS350-24T-4X-EU reached end of sale on October 29, 2024, and its last date of support is October 31, 2029. Software maintenance releases and vulnerability support ended on October 29, 2025. C1300-24T-4X is the current migration model for this port configuration, rather than another discontinued intermediate replacement.

What condition and warranty options does ORM offer for CBS350-24T-4X-EU?

New sealed and certified refurbished CBS350-24T-4X-EU units carry separate ORM coverage: up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Both conditions include 30-day returns; terms apply. Cisco's Enhanced Limited Lifetime Warranty is distinct, with Cisco service ending October 31, 2029.

Does CBS350-24T-4X-EU require a license or subscription?

No, CBS350-24T-4X-EU requires neither a separately purchased feature license nor a software subscription to use its included switch capabilities. All features accompany the hardware purchase, with no minimum subscription term. The EU ending is a regional ordering designation, not a software tier or an additional feature entitlement.

Which older switches does CBS350-24T-4X-EU replace?

CBS350-24T-4X-EU replaces SG350X-24-K9-EU and SG550X-24-K9-EU, both discontinued models. SG350X-24-K9-EU reached end of sale on October 30, 2021; SG550X-24-K9-EU followed on July 30, 2022. CBS350-24T-4X-EU has since reached end of sale itself, and the migration chain now continues to C1300-24T-4X for current procurement.

Does CBS350-24T-4X-EU provide PoE?

No, CBS350-24T-4X-EU provides Ethernet data connections without PoE output on its RJ-45 access ports. Phones, cameras, access points, and other powered devices therefore need their own power arrangements. The current C1300-24P-4X alternative supplies PoE while retaining a 24-port Gigabit access configuration and four 10G SFP+ uplinks.

How many Cisco Business 350 switches can form a hardware stack?

Four supported Cisco Business 350 switches can form one hardware stack, and CBS350-24T-4X-EU is a supported member. Ring and chain topologies use high-speed interconnects. Compatible copper connection choices include SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M; reserve the necessary interfaces and select cable lengths for the physical arrangement.

What routing capabilities does CBS350-24T-4X-EU support?

CBS350-24T-4X-EU supports static routing, RIP v2, and PBR, placing this configuration in the Layer 2+ category. IPv4 routing accommodates 990 static routes and 128 IP interfaces. Routed interfaces can use physical ports, link aggregations, VLAN interfaces, or loopback interfaces, so the interface plan matters before configuration is standardized.

Which optics fit the four 10G uplinks on this Business 350 switch?

SFP-10G-SR and SFP-10G-LR are supported 10G optical choices for the four fixed SFP+ uplinks on CBS350-24T-4X-EU. SFP-10G-SR serves multimode fiber, while SFP-10G-LR supports single-mode links reaching 10 km. Select the transceiver for the fiber type and distance, and include the required link components separately on the PO.

What power input and maximum consumption does CBS350-24T-4X-EU have?

CBS350-24T-4X-EU uses an internal 100-240V AC supply and has a worst-case consumption of 27.54W at 110V or 27.25W at 220V. The supply powers the switch rather than connected endpoints. There is no redundant internal PSU option, so the electrical arrangement must accommodate a single switch power input.

What is the difference between CBS350-24T-4X-EU and CBS350-24P-4X-EU?

CBS350-24P-4X-EU provides PoE+ with a shared 195W budget, whereas CBS350-24T-4X-EU provides no endpoint power. Both models are discontinued, so this comparison concerns matching existing installations rather than selecting a current generation. The T configuration suits separately powered equipment; the P configuration addresses endpoints that require power over their network connections.

What is the difference between CBS350-24T-4X-EU and CBS350-24T-4G-EU?

CBS350-24T-4X-EU carries four 10G SFP+ uplinks, while CBS350-24T-4G-EU carries four 1G SFP uplinks. Both are discontinued non-PoE configurations with Gigabit copper access ports. For an existing-installation requirement, the 4X version addresses faster upstream connections; the 4G version matches an installation whose upstream links remain at Gigabit speed.

What is the difference between CBS350-24T-4X-EU and C1300-24T-4X?

C1300-24T-4X is the current replacement, while CBS350-24T-4X-EU reached end of sale on October 29, 2024. The replacement retains the 24-port Gigabit and four-port 10G SFP+ configuration. CBS350-24T-4X-EU addresses an exact legacy-hardware requirement; C1300-24T-4X suits buyers specifying the current migration model rather than extending a discontinued installation.

Is CBS350-24T-4XEU-RF the same as ORM certified refurbishment?

No, CBS350-24T-4XEU-RF identifies Cisco-remanufactured hardware, while ORM certified refurbishment is a separate condition offered for CBS350-24T-4X-EU. ORM refurbished units are inspected and bench-tested, with firmware verified and configurations wiped to factory default. Specify the exact PID and condition separately so the purchase order distinguishes Cisco remanufacturing from ORM refurbishment.
