CBS350-48FP-4X-EU combines 48 Gigabit PoE+ access ports with four fixed 10G SFP+ uplinks in a managed, Layer 2+ switch. The full-width 1U chassis belongs to the Cisco Business 350 series and connects powered endpoints alongside ordinary Ethernet devices without requiring a removable uplink card. Its copper access interfaces support 10/100/1000 operation, while the fiber interfaces provide connections toward aggregation equipment or other switches. Within the Cisco Business portfolio, this configuration serves small-business networks requiring both endpoint power and faster uplinks. The discontinued CBS350-48P-4X-EU sibling has a lower 370W PoE budget. The EU suffix identifies a regional ordering version rather than a software tier, so regional requirements remain separate from the switch's Ethernet configuration.

176 Gbps switching capacity supports nonblocking forwarding across the installed interfaces. 130.94 Mpps forwarding performance describes operation with 64-byte packets. 740W of shared PoE capacity must be allocated across connected powered devices rather than treated as an independent allowance for every port. Static routing and RIP v2 provide local IP forwarding, while PBR directs traffic according to access-control criteria. CBS350-48FP-4X-EU uses 512 MB of DRAM and 256 MB of flash for its operating software and configuration. A dynamically shared 3 MB packet buffer serves traffic across the ports, and the 16000-entry MAC table accommodates learned Ethernet addresses. Support for 4094 simultaneous VLANs permits separate broadcast domains. STP, RSTP and MSTP provide spanning-tree options, while LACP supports aggregated connections. Browser configuration, a scriptable CLI, Cisco Business Dashboard and the Cisco Business mobile app provide different administration paths. One cooling fan requires an installation location that accommodates active cooling.
ORM Systems supplies CBS350-48FP-4X-EU new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year; both conditions include 30-day returns, terms apply. Certified refurbished units are inspected and bench-tested, every powered port has PoE output verified under load, firmware is verified, and configurations are wiped to factory default. Specify condition, quantity and optics on the PO; Cisco's separate limited lifetime warranty includes next-business-day advance replacement where available, with service ending October 31, 2029. Enterprise and volume orders have PO acceptance, government Net-30, RMA with advance replacement, and regional stock and RMA across the UK, EU, US and MEA.

When a small-business network needs to separate departments while keeping inter-VLAN forwarding local, the switch supports 128 IP interfaces across physical ports, link aggregation groups, VLAN interfaces and loopbacks. Define the required interface layout and upstream routing arrangement before specifying the configuration on the purchase order.
When several branch switches must be prepared before shipment, dual firmware images support upgrade staging, while editable configuration files can be transferred through SCP. Define the approved firmware image, configuration template and recovery procedure, then specify the staging requirements and shipment quantities before releasing the purchase order.
When powered endpoints need operating-hour controls, time-based PoE can turn power on or off according to a user-defined schedule. Account for devices that must remain energized outside business hours, distinguish those ports from scheduled loads, and specify the required power schedules before releasing the purchase order.
Ongoing software and security maintenance
Software maintenance and vulnerability/security support ended October 29, 2025. C1300-48FP-4X is the current successor for buyers requiring a migration away from this discontinued generation.
Multi-Gigabit copper access connections
Copper access interfaces stop at 1Gbps; the 10G interfaces are SFP+ uplinks. Connecting a faster copper endpoint cannot raise its negotiated access speed beyond that limit.

CBS350-48FP-4X-EU identifies a Cisco Business 350 managed switch: 48 denotes 48 Gigabit access ports, FP identifies the full-PoE version with a 740W budget, and 4X identifies four 10G SFP+ uplinks. EU is the regional ordering suffix covering the European Economic Area and additional designated countries.
Cisco Business 350 supports browser management over HTTP/HTTPS, CLI access through the RJ-45 console or SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP. The CLI supports scripting, while the browser interface offers configuration wizards and simple or advanced operating views.
740W is the shared PoE budget of CBS350-48FP-4X-EU, and all 48 copper access ports support PoE+. Connected devices draw from that common allowance rather than receiving separate unrestricted allocations. Add the expected demands of the powered endpoints when sizing the order; port count alone does not establish available power.
CBS350-48FP-4X-EU has four fixed 10G SFP+ uplinks, with supported optical choices including SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber. The uplink interfaces also support 1G operation. Transceiver selection must match the required distance, fiber type and receiving interface rather than the access-port speed.
Four compatible Cisco Business 350 switches form a hardware stack, and CBS350-48FP-4X-EU supports that capability. Ring and chain arrangements are supported. Connection options include SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M copper cables, measuring 1 m, 3 m and 5 m respectively; these connections use 10G interfaces.
CBS350-48FP-4X-EU provides static IPv4 routing, RIP v2 and PBR, with support for 990 static routes and 128 IP interfaces. Interfaces can be associated with physical ports, link aggregation groups, VLANs or loopbacks. These routing functions accompany the hardware rather than requiring a separately purchased software tier.
No, CBS350-48FP-4X-EU requires no separate feature license or mandatory software subscription. Features and functionality accompany the hardware purchase, so there is no subscription tier or minimum term to select for switch operation. The EU suffix is regional and does not identify a different software entitlement.
Yes, CBS350-48FP-4X-EU reached end of sale on October 29, 2024. Software maintenance and vulnerability/security support ended October 29, 2025, while the last date of Cisco support is October 31, 2029. C1300-48FP-4X is the current successor; remaining hardware support does not extend the software-maintenance deadline.
CBS350-48FP-4X-EU replaces the discontinued SG350X-48MP-K9-EU and SG550X-48MP-K9-EU. Their end-of-sale dates were October 30, 2021, and July 30, 2022, respectively. The CBS350 model subsequently became discontinued itself, and its forward migration path now leads to C1300-48FP-4X rather than ending with the Business 350 generation.
CBS350-48FP-4X-EU provides a 740W PoE budget, whereas CBS350-48P-4X-EU provides 370W. Both configurations have 48 Gigabit PoE+ access ports and four 10G SFP+ uplinks, and both are discontinued. The full-PoE version accommodates greater aggregate endpoint demand; the lower-budget version suits smaller combined powered loads.
CBS350-48FP-4X-EU carries four 10G SFP+ uplinks, whereas CBS350-48FP-4G-EU carries four 1G SFP uplinks. Both are discontinued full-PoE configurations. The 4X model suits connections requiring 10G uplink capacity; the 4G model addresses an installed network whose upstream connections remain at Gigabit speed.
CBS350-48FP-4X-EU is discontinued, while C1300-48FP-4X is its current successor for the same 48-port Gigabit full-PoE configuration with four 10G SFP+ uplinks. The CBS350 model addresses installed-base matching; C1300-48FP-4X serves migration purchases seeking the current generation rather than additional hardware from the discontinued Business 350 range.
An internal universal 100-240V AC supply powers CBS350-48FP-4X-EU. Worst-case consumption including PoE reaches 889.35W at 110V or 865.02W at 220V. Circuit planning must account for the switch's own consumption and supplied endpoint power, rather than using the PoE budget alone as the electrical load.
ORM Systems offers CBS350-48FP-4X-EU 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 separate limited lifetime hardware warranty includes next-business-day advance replacement where available, with Cisco service ending October 31, 2029.
