Mixed-Speed Copper Access for Powered Business Endpoints

CBS350-24NGP-4X-UK combines eight access ports supporting 100M/1G/2.5G/5G with sixteen Gigabit access ports, providing managed Layer 2+ switching for small-business networks. PoE+ connects powered endpoints such as wireless access points, IP phones and surveillance cameras. Four fixed 10G uplinks comprise two dedicated SFP+ connections and two copper/SFP+ combo connections; each combo connection activates only one medium at a time. The full-width rack-mount chassis belongs to the Cisco Business 350 Series and requires no removable uplink card. Compared with the discontinued CBS350-24MGP-4X-UK, which has four 2.5G-capable access ports, this configuration provides more multigigabit connections and a higher native access speed. The mixed-speed arrangement accommodates Gigabit endpoints alongside devices requiring faster copper connections.

Technical Details

192 Gbps switching capacity supports the fixed interface configuration, while 142.85 Mpps forwarding performance applies to 64-byte packets. 375W of shared PoE power requires endpoint allocations to remain within the total budget; eight access ports additionally support 60W PoE. Static IPv4/IPv6 routing, RIP v2 and PBR provide local traffic handling without implying enterprise dynamic-routing capabilities. CBS350-24NGP-4X-UK carries 512 MB of DRAM and 256 MB of flash for operation and image storage. A dynamically shared 3 MB packet buffer absorbs traffic bursts across the interfaces, while the MAC table accommodates 16000 entries. STP, RSTP and MSTP address Layer 2 loop control, and LACP supports aggregated connections. Three fans provide active cooling within the 0°C to 50°C operating range. Worst-case consumption reaches 488.9W with PoE, which belongs in upstream electrical sizing rather than being confused with available endpoint power. The Cisco Business switch also supports dual firmware images for upgrade recovery.

Ordering

ORM Systems offers CBS350-24NGP-4X-UK new sealed or certified refurbished. Certified refurbished units are inspected and bench-tested, with every port linked at rated speed, PoE output verified under load on every powered port, firmware verified and configuration wiped to factory default. Specify condition, quantity and delivery region on the purchase order: new units carry up to 3-year extended warranty, refurbished units carry up to 1 year, and every condition includes 30-day returns with terms applying; Cisco’s separate limited lifetime hardware warranty is bounded by October 31, 2029. Enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock and RMA across the UK, EU, US and MEA.

Buying Notes

Buying NotesKey Specs

Security maintenance has ended

Security-sensitive purchases require a lifecycle exception: CBS350-24NGP-4X-UK stopped receiving software maintenance and vulnerability support on October 29, 2025. Applicable hardware service ends October 31, 2029; no direct migration model is available.

Allocate endpoint power individually

Endpoint loads require individual allocation: eight devices at 60W demand 8 × 60W = 480W, exceeding the 375W shared budget before other powered devices are connected. Specify each endpoint’s required allocation before purchase.

Specify fiber connection accessories

Fiber connections require separately ordered SFP-10G-SR or SFP-10G-LR transceivers; specify multimode or single-mode fiber respectively, with the far-end optic and link distance matched before releasing the purchase order.

Legacy Fleet Replacement

An installed SG350X-24PV-K9-UK fleet creates a replacement requirement tied to an exact regional part number. CBS350-24NGP-4X-UK is its named migration model, rather than an interchangeable assumption based on port count. Identify the existing connection media and required condition, then specify matching connection accessories before the purchase order.

Local Routing Consolidation

A small-business network moving inter-VLAN traffic away from an external router must fit within 990 static routes and 128 IP interfaces. Physical ports, link aggregation groups, VLAN interfaces and loopback interfaces can host routing interfaces. Inventory destination networks and interface assignments, then check the complete addressing plan before the purchase order.

Staged Branch Rollout

A branch rollout using repeatable configuration files can stage switches through the scriptable Textview CLI and secure configuration downloads. CLI privilege levels 1, 7 and 15 provide distinct administrative access levels. Establish the staging account, configuration template and acceptance procedure, then specify the quantity and delivery sequence before the purchase order.

Not Suitable If

Continuing security fixes throughout deployment

Security vulnerability support ended October 29, 2025, so this discontinued model cannot meet a requirement for continuing security fixes. No direct migration model is available.

More than eight high-power 60W endpoints

Only eight ports support 60W PoE; the other powered access ports use PoE+. A requirement for nine or more 60W devices exceeds the high-power port count.

Questions & Answers

What does the CBS350-24NGP-4X-UK part number mean?

CBS350-24NGP-4X-UK identifies a Cisco Business 350 managed switch: CBS350 is the family, 24 is the access-port count, NGP identifies the mixed Gigabit/5G PoE configuration, and 4X identifies four 10G uplinks. UK is a regional ordering suffix covering the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia.

How is CBS350-24NGP-4X-UK managed?

CBS350-24NGP-4X-UK is managed through its HTTP/HTTPS web interface, Textview CLI over SSH or Telnet, RJ-45 console, Cisco Business Dashboard, Cisco Business mobile app, and SNMP. The embedded Dashboard probe runs on the switch. Full and menu-based CLI modes support scripted administration rather than browser-only configuration.

Is CBS350-24NGP-4X-UK end of sale?

Yes, CBS350-24NGP-4X-UK reached end of sale on October 29, 2024, and software maintenance and security vulnerability support ended October 29, 2025. The last date of applicable Cisco support is October 31, 2029. No direct migration product is available, so replacement planning must account for a finite support window.

What condition and warranty options does ORM Systems offer for CBS350-24NGP-4X-UK?

ORM Systems supplies CBS350-24NGP-4X-UK new sealed or certified refurbished, with up to 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions include 30-day returns; terms apply. Cisco’s separate limited lifetime hardware warranty is bounded by the last support date, October 31, 2029, and applicable eligibility.

Which older switch does CBS350-24NGP-4X-UK replace?

CBS350-24NGP-4X-UK replaces the discontinued SG350X-24PV-K9-UK, whose end-of-sale date was July 30, 2022. The replacement retains the named 5G PoE purchase category, but the newer model is also discontinued. Treat this as a legacy fleet replacement rather than a migration to a currently sold generation.

How much PoE power does the Business 350 mixed-speed configuration provide?

375W is the shared PoE budget for CBS350-24NGP-4X-UK, with PoE+ across 24 access ports and 60W PoE support on eight. Those eight high-power ports cannot all supply 60W simultaneously because that would require 480W before other endpoints. Size allocations using each connected device’s actual power requirement.

What uplink connections does CBS350-24NGP-4X-UK provide?

Four 10G connections are available on CBS350-24NGP-4X-UK: two dedicated SFP+ ports and two copper/SFP+ combo ports. Each combo activates either its copper connector or its SFP+ cage, not both. SFP-10G-SR supports multimode fiber; SFP-10G-LR supports single-mode fiber, so select media and far-end optics together.

How many Business 350 switches can form a hardware stack?

Four supported Business 350 switches, including CBS350-24NGP-4X-UK, can form a hardware stack managed as one system. Stack interconnects use 10G interfaces, with ring and chain topologies and active/standby control. Allocate inter-switch connections before finalizing uplink usage because connections committed to stacking are not independent network uplinks.

What routing capabilities does the Business 350 mixed-speed switch support?

Static IPv4/IPv6 routing, RIP v2 and PBR are available on CBS350-24NGP-4X-UK, placing the switch in the Layer 2+ category. The static-route limit is 990, with 128 IP interfaces. Routing interfaces can be physical ports, link aggregation groups, VLAN interfaces or loopbacks, so verify the planned inter-VLAN design against those boundaries.

What is the difference between CBS350-24NGP-4X-UK and CBS350-24FP-4X-UK?

CBS350-24NGP-4X-UK provides 375W of PoE power, whereas CBS350-24FP-4X-UK provides 370W. Both models are discontinued, and neither budget permits unrestricted maximum loading of every powered port. The NGP configuration suits existing allocations requiring its 375W ceiling; the FP configuration suits established installations sized within 370W.

What is the difference between CBS350-24NGP-4X-UK and CBS350-24MGP-4X-UK?

CBS350-24NGP-4X-UK has eight 5G-capable access ports; CBS350-24MGP-4X-UK has four 2.5G-capable access ports. Both models are discontinued. The NGP configuration fits an existing fleet needing more 5G endpoint connections, while the MGP configuration fits established 2.5G connection requirements without assuming identical access speeds.

What is the difference between CBS350-24NGP-4X-UK and CBS350-48P-4X-UK?

CBS350-24NGP-4X-UK has 24 access ports, while CBS350-48P-4X-UK has 48. Both models are discontinued. The 24-port configuration suits replacement orders based on a smaller installed patching plan; the 48-port configuration suits denser existing connection requirements. Match the cabling inventory without assuming equivalent endpoint speeds or power allocations.
