CBS350-48P-4X-EU combines 48 Gigabit Ethernet PoE+ access ports and four fixed 10G SFP+ uplinks in a managed Layer 2+ switch. The Business 350 series serves small-office networks connecting computers, IP phones and wireless access points. Its 1U chassis fits a standard equipment rack, while VLAN segmentation separates employee, voice and guest traffic. The discontinued CBS350-48FP-4X-EU increases the endpoint power allowance to 740W for buyers comparing existing fleet configurations. Cisco Business switching provides configurable network functions rather than unmanaged connectivity, so an order should reflect the intended segmentation, upstream connections and endpoint requirements. The fixed uplink architecture does not require a removable network card.

176 Gbps switching capacity provides the switching fabric for access and uplink traffic. 130.94 Mpps forwarding is rated using 64-byte packets, rather than application throughput. 370W of PoE capacity is shared across the powered interfaces, so endpoint allocations must remain within that combined ceiling. Static routing, RIP v2 and PBR support local traffic forwarding, with limits of 990 static routes and 128 IP interfaces. CBS350-48P-4X-EU provides 512 MB of DRAM and 256 MB of flash for its control software and images. A dynamically shared 3 MB packet buffer serves the ports, while the MAC table accommodates 16000 addresses. STP, RSTP and MSTP provide spanning-tree options; LACP supports aggregated connections. Browser configuration, CLI access, SNMP, Cisco Business Dashboard and the Cisco Business mobile app provide management paths. The copper access interfaces do not provide native multigigabit endpoint connections.
ORM Systems supplies CBS350-48P-4X-EU new sealed or certified refurbished; refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, optics bay recognition checked, firmware verified and configurations wiped to factory default. New units carry up to a 3-year extended warranty, certified refurbished units up to 1 year, and every condition has 30-day returns; terms apply. Specify the required condition and quantity on the purchase order. Submit enterprise and volume requirements with the order: POs are accepted, Net-30 is available for government, and regional stock and RMA handling cover the UK, EU, US and MEA, with advance replacement.

When replacing discontinued SG350X-48P-K9-EU or SG550X-48P-K9-EU hardware, this discontinued model is a named migration option, not evidence that existing configurations transfer unchanged. Inventory current port assignments, endpoint requirements and upstream interfaces, then check configuration compatibility and the required support horizon before putting replacement quantities on the PO.
For a branch rollout that reuses a standard configuration, text-editable configuration files allow settings to be prepared before shipment. CLI privilege levels 1, 7 and 15 distinguish access rights. Define the common template, site-specific addressing and administrator permissions before specifying the staging requirements on the PO.
When a troubleshooting bench needs traffic from several connections, port mirroring supports eight source ports feeding one destination port. Reserve the capture destination rather than treating every connection as an endpoint attachment. Identify the analyzer connection, source interfaces and required test configuration before ordering the staging unit.
Ongoing software and security maintenance
Software maintenance and security support ended October 29, 2025, so this discontinued switch does not meet a requirement for ongoing fixes. C1300-48P-4X is the current migration replacement.
Multigigabit copper endpoint connections
Fixed copper access ports support Gigabit Ethernet, not 2.5G or 5G endpoint links. The 10G SFP+ interfaces provide uplinks rather than faster native RJ-45 access connections.

CBS350-48P-4X-EU identifies a Cisco Business 350 managed switch: 48 denotes 48 Gigabit Ethernet access ports, P denotes PoE+, and 4X denotes four 10G SFP+ uplinks. EU is a regional ordering suffix covering the European Economic Area and additional countries, rather than a software license tier.
CBS350-48P-4X-EU supports a web UI over HTTP/HTTPS, CLI access through the RJ-45 console or SSH/Telnet, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. Cisco Network Plug and Play also supports provisioning. Choose the access method, credentials and provisioning workflow before staging the unit.
370W is the total shared PoE budget of CBS350-48P-4X-EU across its 48 PoE+ access ports. The budget is a switch-wide allocation, not a promise that every powered port can draw its individual maximum simultaneously. Add the endpoint allocations together before committing the powered-device list.
SFP-10G-SR and SFP-10G-LR are supported 10G optical options for Cisco Business 350 switches with SFP+ uplinks. SFP-10G-SR uses multimode fiber, while SFP-10G-LR uses single-mode fiber. Match the transceiver type, fiber plant and far-end connection when specifying the uplink accessories for the order.
Cisco Business 350 hardware stacking supports four members on stack-capable models, including CBS350-48P-4X. The stack operates as one managed system and supports ring or chain arrangements, active and standby control, and 10G fiber interconnects. Confirm the participating models and interconnect arrangement before specifying a stack extension.
Static routing, RIP v2 and PBR are available on CBS350-48P-4X-EU, with limits of 990 static routes and 128 IP interfaces. Cisco Business 350 also supports IPv6 packet routing. Size the local addressing and routing design against those interface and static-route limits before deployment.
CBS350-48P-4X-EU uses an internal universal power supply accepting 100-240V AC, rather than an external desktop adapter. The standard package includes a power cord and mounting kit. Specify the appropriate cord for the installation region when ordering existing stock, particularly when the destination differs from the regional PID.
No separate license or subscription is required for CBS350-48P-4X-EU; its switching features are included with the hardware purchase. A term-based software line item is therefore not needed to enable the switch's functions. Hardware condition and connection accessories remain separate purchasing decisions for the order.
CBS350-48P-4X-EU reached end of sale on October 29, 2024, with C1300-48P-4X named as its migration replacement. Software maintenance and security support ended October 29, 2025. The last date of applicable Cisco service and support is October 31, 2029, subject to the relevant entitlement terms.
CBS350-48P-4X-EU is a named replacement for SG350X-48P-K9-EU and SG550X-48P-K9-EU. Those predecessors reached end of sale on October 30, 2021 and July 30, 2022, respectively. CBS350-48P-4X-EU is itself discontinued, so historical replacement compatibility should not be confused with a current-product recommendation for a new deployment.
CBS350-48FP-4X-EU has a 740W PoE budget, compared with 370W on CBS350-48P-4X-EU. Both are discontinued. The higher-budget version addresses larger powered-endpoint allocations in existing Business 350 installations; the 370W model fits equipment lists whose combined allocation remains within the lower shared limit.
CBS350-48P-4X-EU has four 10G SFP+ uplinks; CBS350-48P-4G-EU has four 1G SFP uplinks. Both are discontinued, so this comparison concerns existing-fleet extensions and spares. The 4X version fits 10G upstream requirements, while the 4G version matches installations retaining Gigabit uplink connections.
C1300-48P-4X is the current migration replacement for the discontinued CBS350-48P-4X-EU, whose end-of-sale date was October 29, 2024. Buyers maintaining an existing CBS350 fleet may require the older model for fleet consistency; buyers specifying new equipment should include the current replacement in their hardware evaluation.
CBS350-48P-4X-EU is offered new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's Limited Lifetime warranty includes next-business-day advance replacement where available, with Cisco service ending October 31, 2029.
