CBS350-48NGP-4X-UK pairs eight 5G-capable PoE+ copper access ports with forty Gigabit PoE+ access ports in a Layer 2+ managed switch for small-business networks. The fixed uplink arrangement combines two dedicated 10G SFP+ slots with two 10G copper/SFP+ combo connections; each combo connection uses copper or fiber rather than both simultaneously. A full-width 1U rack chassis places this configuration in the Cisco Business 350 Series for office connectivity, IP telephony, wireless access points and surveillance devices. Access connections support different endpoint speeds, while uplink media must match the connections at the other end. CBS350-24NGP-4X-UK allocates 375W to powered devices and is also discontinued; the higher-budget configuration here accommodates larger shared endpoint-power allocations.

240 Gbps switching capacity supports simultaneous switching across the mixed-speed connections. 178.56 Mpps forwarding performance specifies packet handling with 64-byte packets. 740W of shared PoE allocation must be apportioned to connected endpoints rather than treated as an independent allowance at every port. Static routing accommodates 990 routes and 128 IP interfaces; RIP v2 exchanges routes, and PBR directs traffic using access control lists. CBS350-48NGP-4X-UK has 512 MB of DRAM and 256 MB of flash, while a 6 MB dynamically shared packet buffer serves all ports. The mixed-speed PoE+ access switch supports 4094 VLANs for segmentation and 16000 learned MAC addresses for forwarding. STP/RSTP/MSTP control Layer 2 loops, and LACP groups Ethernet links. Management includes an HTTP/HTTPS web interface and CLI access over SSH or Telnet. 916W maximum draw including PoE belongs in the cabinet AC load plan; fanless operation is unavailable because active cooling uses four fans.
Specify CBS350-48NGP-4X-UK as new sealed or certified refurbished, with condition, quantity and regional ordering variant on the purchase order. Certified refurbished units are inspected and bench-tested, including PoE output under load on every powered port; firmware is verified and configuration wiped to factory default. ORM Systems warranty coverage is up to 3-year extended for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply. Cisco's Limited Lifetime warranty is bounded by May 31, 2029, while enterprise and volume POs are accepted with Net-30 for government and RMA with advance replacement across UK, EU, US and MEA.

During a wireless or connected-device refresh, higher-draw endpoints need to be assigned to the eight access ports supporting 60W PoE. The remaining powered connections use PoE+. List each endpoint's requested power and reserve the appropriate ports before sizing the combined allocation on the purchase order.
When expanding an existing hardware stack, the interconnection layout must be specified rather than treating the new member as an independent switch. Ring and chain arrangements use active and standby stack control. Confirm the intended topology, member assignments and interconnect media before adding the unit to the purchase order.
When standardizing management across several offices, the embedded Cisco Business Dashboard probe removes the requirement for a separate on-site probe host. Operators can also use the Cisco Business mobile app for local administration. Specify the Dashboard integration and administrative access plan before ordering units for the branch rollout.
5G connectivity on every access port
CBS350-48NGP-4X-UK provides eight access ports reaching 5G; the other forty access ports stop at Gigabit Ethernet. All-port 5G requirements exceed this configuration.
60W power on every powered port
CBS350-48NGP-4X-UK supports 60W PoE on eight access ports, not all powered connections. The remaining forty access ports provide PoE+ within the shared power allocation.

CBS350-48NGP-4X-UK identifies a Business 350 managed PoE+ switch with 48 access ports and four 10G uplinks. CBS350 denotes the series; 48 denotes access-port count; NGP denotes forty Gigabit ports plus eight 5G-capable ports; 4X denotes the uplinks; UK selects the regional order for the United Kingdom and associated markets.
CBS350-48NGP-4X-UK supports a web UI over HTTP/HTTPS, CLI over SSH or Telnet, an RJ-45 console, Cisco Business Dashboard, Cisco Business mobile app, SNMP and Cisco Network Plug and Play. The embedded Dashboard probe runs on the switch, avoiding a separate on-site probe host.
CBS350-48NGP-4X-UK is discontinued: end of sale was May 30, 2024, and the last date of support is May 31, 2029. Security maintenance ended May 30, 2025. No current migration product is available for this model, so the remaining hardware-support period does not include continuing security maintenance.
ORM Systems offers CBS350-48NGP-4X-UK new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Cisco's Limited Lifetime warranty is bounded by May 31, 2029. Returns cover every condition for 30 days; terms apply. Refurbished units are inspected and bench-tested.
CBS350-48NGP-4X-UK replaces SG350X-48PV-K9-UK, whose end-of-sale date was July 30, 2022. That replacement relationship identifies the newer hardware for an existing installation, but CBS350-48NGP-4X-UK is also discontinued. No current migration product is available for this configuration, so neither part represents a current-generation migration endpoint.
CBS350-48NGP-4X-UK provides a shared 740W PoE budget across 48 powered access ports, with eight ports supporting 60W PoE. The remaining access ports support PoE+. Individual port capability does not create additional system power, so endpoint allocations must fit the shared budget rather than assume every port can draw its maximum simultaneously.
CBS350-48NGP-4X-UK provides four logical 10G uplinks: two dedicated SFP+ connections and two copper/SFP+ combo connections. Each combo connection activates only one medium at a time. Fiber connections require separate optics such as SFP-10G-SR or SFP-10G-LR; the fixed uplinks do not require a removable network module.
Four CBS350-48NGP-4X-UK switches can form a hardware stack managed as one system. Stack interconnections use high-speed 10G interfaces, with ring and chain arrangements and active/standby stack control. Link aggregation can span stack members. Specify the interconnection topology and media alongside the switches rather than treating stacking as dashboard grouping.
CBS350-48NGP-4X-UK supports static routing, RIP v2 and PBR, with 990 static routes and 128 IP interfaces. Routing interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopback interfaces. PBR selects next hops using access control lists, while RIP v2 supplies the dynamic routing function.
CBS350-48NGP-4X-UK uses an internal universal AC power supply accepting 100-240V AC at 50-60 Hz. Maximum consumption including PoE is 916W; the switch is not an external-adapter configuration. The regional ordering variant determines the supplied power connection, so confirm the required regional configuration when preparing the purchase order.
CBS350-48NGP-4X-UK provides a 740W PoE budget, whereas CBS350-24NGP-4X-UK provides 375W. Both configurations are discontinued without a current migration product. For legacy replacement orders, the lower-budget model suits smaller aggregate endpoint-power allocations; the higher-budget model suits orders requiring a larger shared allowance after individual endpoint demand is checked.
CBS350-48NGP-4X-UK uses an internal AC power supply, whereas CBS350-8S-E-2G-UK uses an external AC adapter. Both switches are discontinued without a current migration product. The external-adapter configuration suits replacement orders retaining that power arrangement; the internal-supply configuration suits buyers standardizing legacy equipment around an AC-powered chassis.
CBS350-48NGP-4X-UK has 48 access ports, whereas CBS350-12NP-4X-UK has 12 access ports. Both switches are discontinued without a current migration product. For legacy replacement orders, the 12-port configuration suits limited endpoint counts, while the 48-port configuration suits higher-density requirements. Confirm the required endpoint count before selecting the replacement hardware.
240 Gbps switching capacity and 178.56 Mpps forwarding performance apply to CBS350-48NGP-4X-UK with 64-byte packets. A 6 MB packet buffer is dynamically shared across all ports. The forwarding table holds 16000 MAC addresses, while support for 4094 VLANs defines the maximum simultaneous segmentation scale.
Yes, CBS350-48NGP-4X-UK is a full-width 1U rack-mount switch measuring 440 mm wide, 350 mm deep and 44 mm high, with a weight of 5.95 kg. The mounting kit is included. Four fans provide active cooling, and the operating temperature range is 0°C to 50°C.
