CBS350-48NGP-4X-EU combines eight 5G-capable access ports with forty Gigabit access ports in a managed Layer 2+ PoE+ switch for small-business networks. Four fixed 10G uplinks comprise two copper/SFP+ combo interfaces and two dedicated SFP+ cages. The full-width 1U rack chassis belongs to the Cisco Business 350 series and connects powered wireless access points, IP phones and conventional office endpoints. CBS350-12NP-4X-EU, a discontinued sibling, carries a smaller 375W PoE allocation. The Cisco Business line provides browser, command-line and centralized administration for sites that need configuration control rather than unmanaged connectivity. Copper and fiber uplink choices let the purchase match the existing distribution connection without adding a removable network module.

240 Gbps switching capacity defines the switching fabric available for access and uplink traffic, while 178.56 Mpps forwarding performance provides the packet-processing figure for traffic sizing. 740W of shared PoE power covers the combined endpoint allocation rather than an unrestricted maximum on every powered connection. Static routing, RIP v2 and PBR support routed traffic handling; IPv4 static configuration permits 990 routes and 128 IP interfaces. CBS350-48NGP-4X-EU carries 512 MB of DRAM and 256 MB of flash for switch operation and stored software images. A 6 MB packet buffer is shared across the ports, while the 16K MAC address table and 4094-VLAN capacity set endpoint-learning and segmentation limits. STP/RSTP/MSTP control Layer 2 loops, and LACP supports eight groups with eight active ports per group. SNMP versions 1, 2c and 3 expose monitoring and management functions. Time-based PoE allows endpoint power delivery to follow a configured schedule rather than remain continuously enabled.
Order CBS350-48NGP-4X-EU new sealed or certified refurbished, specifying condition, quantity and delivery region 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. New units carry up to a 3-year extended ORM warranty; certified refurbished units carry up to 1 year, with 30-day returns on every condition, terms apply; Cisco's limited lifetime coverage is bounded by its May 31, 2029 service end date. ORM Systems accepts POs, offers Net-30 for government, and supports enterprise and volume orders with RMA advance replacement across UK, EU, US and MEA.

When replacing installed SG350X-48PV-K9-EU hardware, treat this order as a discontinued-to-discontinued refresh rather than a move to a current successor. The predecessor reached end of sale on July 30, 2022. Record the installed configuration requirements and assess whether discontinued hardware remains acceptable before issuing the PO.
When an endpoint order includes devices requiring 60W PoE, the Cisco Business 350 configuration provides eight ports supporting that output. Allocate those devices to the eligible ports instead of treating every powered connection as interchangeable. Check endpoint compatibility and the combined power allocation before specifying the port assignments on the PO.
When a staging bench needs packet captures before a Cisco Business 350 deployment is approved, port mirroring can send traffic from eight source ports to one destination port. Reserve the analyzer connection separately from endpoint connections, and specify the capture configuration and test-port allocation before the PO.
More than eight 5G access ports
CBS350-48NGP-4X-EU provides eight 5G-capable access ports; the remaining forty access ports top out at 1G, so larger multigigabit endpoint counts exceed this configuration.
Four simultaneous copper 10G uplinks
CBS350-48NGP-4X-EU has two copper-capable 10G uplink interfaces. The other two uplinks are dedicated SFP+ connections, preventing a four-link, all-copper 10G uplink configuration.
Continuing Cisco security maintenance
Cisco vulnerability and security support for CBS350-48NGP-4X-EU ended May 30, 2025. No migration product is available for this model, so continued security maintenance cannot accompany this purchase.
More than four stack members
CBS350-48NGP-4X-EU supports hardware stacks containing four members maximum. A requirement for five or more switches in one hardware stack exceeds the supported member limit.

CBS350-48NGP-4X-EU breaks down as CBS350 for Business 350, 48 for access-port count, NGP for mixed Gigabit/5G PoE+, 4X for four 10G uplinks, and EU for regional ordering. The EU suffix covers the European Economic Area plus additional markets; the mixed-speed configuration includes eight 5G-capable ports.
The Cisco Business 350 supports browser management over HTTP/HTTPS, a full or menu-based CLI through the RJ-45 console or SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP versions 1/2c/3. Its embedded Dashboard probe removes the need for a separate probe host, while CLI scripting supports configuration handling.
CBS350-48NGP-4X-EU reached end of sale May 30, 2024, with final Cisco hardware support May 31, 2029. Software maintenance and vulnerability/security support ended May 30, 2025. No Cisco migration product is available for this model, so a purchase remains a legacy-hardware order rather than a transition to a named current replacement.
ORM Systems offers CBS350-48NGP-4X-EU new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are available for 30 days on every condition; terms apply. Cisco's platform warranty is limited lifetime with next-business-day advance replacement where available, but Cisco service ends May 31, 2029.
CBS350-48NGP-4X-EU replaces discontinued SG350X-48PV-K9-EU, whose end-of-sale date was July 30, 2022. The predecessor is a 48-port 5G PoE stackable managed switch. This replacement is also discontinued; confirm the installed configuration and assess lifecycle acceptance if matching legacy equipment is the reason for the purchase.
CBS350-48NGP-4X-EU provides a shared 740W PoE budget across 48 powered access ports, including eight ports that support 60W PoE. PoE+ and legacy PoE endpoints use the same overall allocation. Size the combined endpoint load against the shared budget and verify high-draw device compatibility rather than assuming every port supports 60W.
CBS350-48NGP-4X-EU has four fixed 10G uplinks: two copper/SFP+ combo interfaces and two dedicated SFP+ ports. Each combo interface accepts one medium at a time, so its copper connector and cage do not add independent links. SFP-10G-SR supports multimode fiber; SFP-10G-LR supports single-mode fiber. Specify the medium for each uplink on the order.
The Cisco Business 350 hardware-stacking limit is four supported members, and CBS350-48NGP-4X-EU supports this mode. Ring and chain topologies use 10G interconnects. Compatible 10G copper coax cable options include SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M. Allocate the interconnect ports and select the cable length before the PO.
Yes, CBS350-48NGP-4X-EU supports inter-VLAN routing, static routing, RIP v2 and PBR. IPv4 static configuration permits 990 routes, with 128 IP interfaces supported. Physical ports, link aggregation groups, VLAN interfaces and loopback interfaces can host routed configuration. Select static routing or RIP v2 according to the existing design before purchase.
Yes, CBS350-48NGP-4X-EU is a 1U rack-mount switch measuring 440 mm wide, 350 mm deep and 44 mm high, with a 5.95 kg weight. A mounting kit is included with the device and is not sold separately as a spare accessory. Plan rack depth and cable clearance before ordering.
CBS350-48NGP-4X-EU has a 740W PoE budget, compared with 375W for CBS350-12NP-4X-EU. Both models are discontinued, and neither has a named Cisco migration product. The larger allocation suits higher combined powered-endpoint requirements; the lower-budget model serves legacy orders sized for a lower aggregate endpoint load.
CBS350-48NGP-4X-EU has a worst-case 916W draw at 110V AC with PoE; the 220V AC figure is 914.4W. Without PoE output, the corresponding worst-case system figures are 94.1W and 93.7W. Use the PoE-inclusive figure for power planning, not the system-only figure that excludes power delivered to endpoints.
The Cisco Business 350 mixed-speed 48-port model provides 240 Gbps switching capacity and 178.56 Mpps forwarding performance, with 6 MB of packet buffers shared across all ports. Its MAC address table holds 16K addresses. Size traffic handling using these model-specific figures rather than performance figures from another Business 350 configuration.
CBS350-48NGP-4X-EU uses an internal universal AC power supply accepting 100-240V AC at 50-60 Hz. The device package includes a power cord and mounting kit. Accessories such as the power supply and mounting kit are not available as separately orderable spares; malfunctioning accessory replacement requires a support case.
