Managed Access for Powered Small Business Networks

CBS350-24FP-4X-EU is a managed Layer 2+ access switch with 24 Gigabit Ethernet PoE+ ports and four fixed 10G SFP+ uplinks for small-business networks. The rack-mount 1U chassis combines copper endpoint connections with fiber aggregation in the Cisco Business 350 Series, without requiring a removable uplink card. IP phones, wireless access points, and cameras share the available endpoint power allocation. The discontinued CBS350-24P-4X-EU provides a lower 195W PoE budget at the same copper-port density. Private VLANs and protected ports let an administrator restrict communication between attached devices, while eight hardware queues support traffic prioritization. This Gigabit PoE+ access switch combines endpoint connectivity with limited routing for office networks rather than an unrestricted dynamic-routing feature set.

Technical Details

128 Gbps switching capacity provides nonblocking operation across the installed Ethernet interfaces. 95.23 Mpps forwarding at 64-byte packet sizes defines the packet-processing ceiling for small-frame traffic. A 370W shared PoE budget requires the powered-device allocation to remain within the available pool. Static routing, RIP v2, and PBR provide local traffic handling, with support for 990 static routes and 128 IP interfaces. CBS350-24FP-4X-EU carries 512 MB of DRAM and 256 MB of flash for its control software and stored files. A dynamically shared 1.5 MB packet buffer serves the ports collectively. STP, RSTP, MSTP, and LACP support loop control and link aggregation, while an embedded probe connects Cisco Business Dashboard without a separate probe appliance. Browser access, Textview CLI, and SNMP provide additional administration paths. A maximum 451.8W draw including PoE establishes the upper input-power figure to use when sizing the AC feed.

Ordering

Order CBS350-24FP-4X-EU in new sealed or certified refurbished condition, and specify the required transceivers and quantity on the PO. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, optics bay recognition checked, firmware verified, and configuration wiped to factory default. ORM provides up to a 3-year extended warranty for new units, up to 1 year for certified refurbished units, and 30-day returns on every condition, terms apply; Cisco's separate limited lifetime hardware warranty, where applicable, ends no later than October 31, 2029. For enterprise and volume orders, POs are accepted, with Net-30 for government and RMA with advance replacement.

Best For

Voice Endpoint Rollout

When a branch rollout adds phones alongside existing data endpoints, automatic voice VLAN assignment and LLDP-MED discovery provide separate controls for voice classification and endpoint identification. The managed switch can apply Auto Smartports roles to discovered devices. Specify the voice VLAN, discovery settings, and endpoint configuration requirements before placing the PO.

Existing Stack Expansion

When an existing installation needs another stack member, the hardware stack supports ring or chain arrangements and active/standby stack control. Cross-stack link aggregation allows an aggregate to span members rather than terminate on one chassis. Confirm the existing stack models, selected topology, and required interconnects before ordering the additional unit.

Lab Image Staging

When replacement units must be prepared before a maintenance window, dual firmware images and text-editable configuration files support a repeatable staging process. The USB Type-A interface provides local file and image handling, while configurations can be transferred between switches. Specify the required firmware image and configuration acceptance checks before the PO.

Not Suitable If

Ongoing security maintenance releases

Security vulnerability support ended October 29, 2025. For a new installation requiring ongoing security maintenance, select the current C1300-24FP-4X successor instead of this discontinued model.

Multi-Gigabit copper endpoint connections

The fixed RJ-45 access ports stop at Gigabit Ethernet. The faster SFP+ uplinks do not provide Multi-Gigabit copper access for attached endpoints.

Fanless equipment requirements

The chassis contains one cooling fan and produces 34.8 dBA at 25°C. The switch does not meet a specification requiring fanless equipment.

Questions & Answers

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

CBS350-24FP-4X-EU identifies a Cisco Business 350 managed switch: CBS350 is the series, 24 is the Gigabit copper port count, FP denotes Full PoE, and 4X denotes four 10G SFP+ uplinks. EU is a regional ordering suffix covering the European Economic Area and additional markets, not a software license tier.

How is CBS350-24FP-4X-EU managed?

CBS350-24FP-4X-EU supports a browser-based HTTP/HTTPS interface, Textview CLI through the RJ-45 console or SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP. An embedded Dashboard probe runs on the switch, while SNMP versions 1, 2c, and 3 support external management stations.

How much PoE power does CBS350-24FP-4X-EU provide?

370W is the shared PoE budget of CBS350-24FP-4X-EU across its 24 PoE+ copper ports. The Full PoE designation does not remove that aggregate limit. Size the connected phones, access points, and cameras against their combined power requirements rather than treating every powered port as having an independent budget.

Which uplinks and optics does CBS350-24FP-4X-EU support?

CBS350-24FP-4X-EU has four fixed 10G SFP+ uplinks rather than an uplink expansion bay. Compatible connections include SFP-10G-SR for multimode fiber, SFP-10G-LR for single-mode fiber, and SFP-H10GB-CU1M for a 1 m copper direct-attach connection. Select the connection medium and matching parts separately for the intended link.

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

Four supported Cisco Business 350 switches can form one hardware stack, and CBS350-24FP-4X-EU supports that capability. The stack operates with unified management and supports ring or chain arrangements, active/standby control, and cross-stack link aggregation. Confirm that every proposed member is a stack-capable model before specifying the interconnections.

What routing capabilities does CBS350-24FP-4X-EU have?

CBS350-24FP-4X-EU supports static routing, RIP v2, and PBR, placing it in the Layer 2+ category for this configuration. The switch supports 990 static routes and 128 IP interfaces. Those static-route and interface limits are separate measurements and should not be treated as a combined dynamic-route scale figure.

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

Yes, CBS350-24FP-4X-EU reached end of sale on October 29, 2024. Software maintenance and security vulnerability support ended October 29, 2025, and the last date of support is October 31, 2029. C1300-24FP-4X is the current successor for buyers moving away from this discontinued hardware.

Which older switches did CBS350-24FP-4X-EU replace?

CBS350-24FP-4X-EU replaced SG350X-24MP-K9-EU, SG550X-24MP-K9-EU, and SG550X-24MPP-K9-EU. The first reached end of sale October 30, 2021; the latter two reached end of sale July 30, 2022. Because the replacement is itself discontinued, a new migration purchase should follow the chain forward to C1300-24FP-4X.

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

CBS350-24FP-4X-EU provides a 370W PoE budget, while CBS350-24P-4X-EU provides 195W. Both models have 24 Gigabit PoE+ access ports and four 10G SFP+ uplinks, and both are discontinued. The higher-budget model suits larger combined endpoint loads; the lower-budget model suits installations whose allocated demand remains within 195W.

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

CBS350-24FP-4X-EU carries four 10G SFP+ uplinks, whereas CBS350-24FP-4G-EU carries four 1G SFP uplinks. Both discontinued models provide 24 Gigabit PoE+ access ports and a 370W shared power budget. The 4X model suits existing 10G aggregation links; the 4G model suits retained 1G fiber connections.

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

CBS350-24FP-4X-EU is discontinued, while C1300-24FP-4X is its current successor in the Catalyst 1300 family. Both configurations provide 24 Gigabit Full PoE access ports and four 10G SFP+ uplinks. The older model serves existing-hardware matching requirements; the successor suits buyers purchasing a current replacement rather than retaining the discontinued generation.

What rack space and cooling does the Cisco Business 350 configuration require?

The Cisco Business 350 configuration occupies 1U and measures 445 mm wide, 345 mm deep, and 44 mm high, with a weight of 4.6 kg. One cooling fan is fitted, so this is not a fanless model. Allow for the chassis depth and cable connections when selecting the rack position.

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

ORM offers CBS350-24FP-4X-EU new sealed or certified refurbished, with 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 separate limited lifetime hardware warranty, where applicable, is bounded by the last support date of October 31, 2029.
