CBS350-12NP-4X leads with compact multigigabit PoE access: it is a managed Layer 3 network switch with 12 fixed 100M/1G/2.5G/5G RJ-45 access ports and four fixed 10G uplinks. The uplink set comprises two 10G copper/SFP+ combo ports and two dedicated SFP+ ports, so copper, fiber, or direct attach handoffs are selected per uplink without installing a separate module. PoE+ service is available across the access ports, with eight ports supporting 60W PoE for higher-draw endpoints. The chassis is a rack-mount 1U member of the Cisco Business 350 Series Managed Switches for compact wiring closets and high-speed endpoint zones. The model concentrates every access port on multigigabit RJ-45 rather than mixing Gigabit and multigigabit access lanes. CBS350-24NGP-4X differs by providing 24 PoE ports, split between 16 Gigabit access ports and eight 5G-capable access ports.
200 Gbps switching capacity keeps the access edge nonblocking as multigigabit endpoint traffic moves toward 10G uplinks. 148.80 Mpps forwarding rate supports dense small-packet flows from wireless, voice, camera, and workstation segments. 375W PoE budget is allocated across 12 powered access ports, giving engineers room to balance endpoint draw rather than treating every port as a simultaneous maximum-power load. RIP v2, IPv4 routing, IPv6 routing, policy-based routing, routed physical interfaces, routed LAGs, VLAN interfaces, and loopback interfaces place inter-VLAN routing and route control inside the access layer. STP/RSTP/MSTP, LACP, 802.1Q VLANs, IGMP snooping, LLDP-MED, DHCP snooping, Dynamic ARP Inspection, and IP Source Guard anchor loop prevention, aggregation, segmentation, discovery, and edge security policies. CBS350-12NP-4X uses 512 MB DRAM, 256 MB flash, a 3 MB packet buffer, and a 16000-entry MAC table. Management runs through the web interface, Cisco Business Dashboard, the Cisco Business mobile app, SNMP v1/v2c/v3, CLI, and Cisco Network Plug and Play.
CBS350-12NP-4X fits the SMB access tier where Wi-Fi access points, IP phones, surveillance cameras, printers, workstations, and small servers need powered copper links above Gigabit speeds. Hardware stacking supports up to four compatible Cisco Business 350 units under one management system, with active/standby stack control, ring or chain topology, hot swap of members, cross-stack LAGs, and 10G fiber stack interconnects. The 1U rack profile suits wiring closets that need multigigabit density without moving to a larger 24-port or 48-port access chassis. ORM Systems supplies this switch new and certified refurbished for procurement teams standardizing Cisco Business switching. Certified refurbished units receive port, PoE, uplink, fan, firmware, and management checks before dispatch.

CBS350-12NP-4X sits in an access closet and terminates high-speed copper runs from Wi-Fi access points, phones, cameras, and workstations on 12 100M/1G/2.5G/5G PoE+ ports. The 375W PoE budget supports dense powered endpoints, including 60W PoE on eight ports. Engineers place VLANs, QoS, 802.1X, DHCP snooping, and PoE policy at the powered edge, then hand traffic northbound through four 10G uplinks. The result is powered multigigabit access with local segmentation and fewer oversubscribed copper runs across compact closet refreshes and expansions.
CBS350-12NP-4X presents a compact access block to distribution using four 10G uplinks arranged as two 10G copper/SFP+ combo ports and two dedicated SFP+ ports. Engineers match each uplink to copper, DAC, or fiber handoff requirements, then configure LACP, trunks, routed interfaces, or VLAN interfaces according to the campus design. The access layer keeps 5G powered endpoints local while forwarding northbound traffic at 10G. The result is a cleaner access-to-distribution boundary with predictable uplink capacity and media selection.
Several compatible Cisco Business 350 switches form a hardware stack of up to four units, with CBS350-12NP-4X contributing 12 multigigabit PoE+ access ports and four 10G uplink ports per member. Operations teams manage the stack through one IP address, shared control behavior, active/standby stack control, and cross-stack features such as LAGs, VLANs, QoS, and port mirroring. Engineers standardize stacking links, firmware, VLAN templates, and PoE allocation before expanding a closet. The result is higher powered access density with unified administration and controlled failover behavior.

The Cisco CBS350-12NP-4X is a Cisco Business 350 Series managed switch with 12 multigigabit PoE+ access ports and four 10G uplink ports. It is built for compact access networks that need 100M, 1G, 2.5G, and 5G copper connectivity, powered endpoint support, Layer 2 switching, Layer 3 routing, web management, and hardware stacking in a rack-mountable form factor.
CBS350 identifies the Cisco Business 350 managed switch family, while 12NP-4X identifies this specific multigigabit PoE model with 12 100M/1G/2.5G/5G PoE+ ports and four 10G uplinks. Cisco uses country or region suffixes such as CBS350-12NP-4X-UK for ordering, so buyers should match the suffix to the deployment region.
CBS350-12NP-4X is a managed switch. It supports browser-based configuration, Cisco Business Dashboard, Cisco Business mobile app, SNMP, CLI access, VLANs, QoS, security controls, link aggregation, IPv4 and IPv6 routing, and true stacking. That management feature set separates it from unmanaged desktop switches used only for basic Ethernet fan-out.
CBS350-12NP-4X sits in the Cisco Business 350 managed switch lineup as a compact multigigabit PoE access model. It is positioned above basic Gigabit PoE models because it adds 5G copper access ports, 10G uplinks, Layer 3 functions, and hardware stacking. It suits buyers standardizing on Cisco Business rather than Catalyst enterprise switching.
Cisco CBS350-12NP-4X has 12 access ports supporting 100M, 1G, 2.5G, and 5G speeds, plus four 10G uplink ports. The uplink layout is two 10G copper/SFP+ combo ports and two dedicated SFP+ ports. Each combo port uses either the copper interface or the SFP+ slot at one time.
CBS350-12NP-4X provides 200 Gbps switching capacity and 148.80 mpps forwarding rate with 64-byte packets, according to Cisco Business 350 Series specifications. Cisco lists the switch family as wire-speed and nonblocking, which matters for dense multigigabit access designs where 5G endpoint traffic feeds 10G uplinks and stack interconnects.
CBS350-12NP-4X provides a 375W PoE power budget across its 12 multigigabit PoE+ access ports. Cisco specifies that eight of those ports support 60W PoE. That mix suits powered Wi-Fi access points, IP phones, surveillance cameras, and other endpoints that need data and power over the same copper cabling.
CBS350-12NP-4X supports advanced Layer 2 switching features such as VLANs, 802.1Q tagging, STP variants, LACP, IGMP snooping, voice VLAN, and port security. It also supports Layer 3 functions including IPv4 routing, IPv6 routing, routed physical ports, routed LAGs, VLAN interfaces, loopback interfaces, RIP v2, and policy-based routing.
Cisco CBS350-12NP-4X is managed through the built-in web interface, Cisco Business Dashboard, Cisco Business mobile app, SNMP versions 1, 2c, and 3, and CLI access. The switch also supports Cisco Network Plug and Play for provisioning workflows. These options give administrators graphical, mobile, monitoring, and command-line paths for configuration.
CBS350-12NP-4X supports hardware stacking in the Cisco Business 350 Series. Cisco lists up to four units in a stack and up to 200 ports managed as a single system with hardware failover. The family supports active/standby stack control, ring and chain stacking, hot swap of stack members, and 10G fiber stack interconnects.
Cisco CBS350-12NP-4X is used as a multigigabit PoE access switch for networks with high-speed endpoints and limited rack space. Its 12 5G-capable copper ports connect powered devices at the edge, while the four 10G uplinks carry aggregated traffic toward distribution, core, firewall, storage, or server access switching layers.
CBS350-12NP-4X fits small and midsize access deployments that need fewer than 24 multigigabit copper ports in a single switch but still require PoE, 10G uplinks, VLAN segmentation, and Layer 3 routing. It is also useful in larger networks as a dedicated high-speed endpoint switch within a wiring closet or lab network.
CBS350-12NP-4X suits bandwidth-heavy access workloads such as Wi-Fi 6 access point uplinks, IP telephony with voice VLANs, surveillance camera aggregation, workstation access, and mixed endpoint networks. The 5G copper ports reduce the need to jump directly to 10G access switching, while the 375W PoE budget supports powered device consolidation.
CBS350-12NP-4X works in Cisco Business 350 hardware stacks where multiple compatible models operate under one management IP address. A stack helps standardize VLANs, QoS, LAGs, and port mirroring across several access switches. The 12NP model adds multigigabit PoE density to stacked closets without moving to a larger 24-port or 48-port unit.
CBS350-12NP-4X integrates with Cisco Business Dashboard and the Cisco Business mobile app. Cisco Business Dashboard supports an embedded probe running on Business 350 switches, which avoids a separate local probe appliance or virtual machine. The switch also supports Cisco Network Plug and Play, web management, SNMP, and CLI administration.
CBS350-12NP-4X uses two dedicated SFP+ uplinks and two 10G copper/SFP+ combo uplinks. Cisco lists compatible 10G options such as SFP-10G-SR, SFP-10G-LR, SFP-10G-SR-S, SFP-10G-LR-S, and SFP-H10GB-CU direct attach cables. It also lists 1G SFP options including GLC-SX-MMD, GLC-LH-SMD, and GLC-TE for short-reach, long-reach, or in-rack uplink connections.
CBS350-12NP-4X integrates with powered Ethernet endpoints such as Wi-Fi access points, IP phones, surveillance cameras, workstations, printers, and small servers. The switch supports 802.3af PoE, 802.3at PoE+, 60W PoE on eight ports, voice VLAN, LLDP, 802.1X authentication, DHCP snooping, and QoS features used in mixed endpoint access networks.
CBS350-12NP-4X supports standards used across Cisco Business 350 switches, including IEEE 802.3 Ethernet, 802.3ab Gigabit Ethernet, 802.3an 10GBASE-T, 802.3ae 10G Ethernet over fiber, 802.1Q VLANs, 802.1X authentication, 802.3ad LACP, 802.3af PoE, 802.3at PoE+, and 802.3az Energy Efficient Ethernet. These standards support interoperable switching, access control, power delivery, and efficient link operation.
CBS350-12NP-4X is the stronger choice when the access layer needs 5G copper ports and four 10G uplinks. CBS350-8MP-2X provides eight 100M/1G/2.5G PoE+ ports and two 10G copper/SFP+ combo ports with the same 375W PoE budget. CBS350-12NP-4X adds more multigigabit access bandwidth and uplink headroom for Wi-Fi access point clusters.
CBS350-12NP-4X concentrates the access layer around 12 ports that reach 5G, while CBS350-24MGP-4X mixes 20 Gigabit PoE+ ports with four 100M/1G/2.5G PoE+ ports. Both models include four 10G uplinks and a 375W PoE budget. CBS350-12NP-4X suits denser high-speed endpoints, while CBS350-24MGP-4X suits broader Gigabit endpoint counts.
CBS350-24NGP-4X is the next larger mixed-access model, with 16 Gigabit PoE+ ports, eight 5G-capable PoE+ ports, four 10G uplinks, and a 375W PoE budget. CBS350-12NP-4X provides fewer total access ports but gives all 12 access ports 5G capability, which suits smaller high-speed access zones without increasing chassis size or power budget.
CBS350-48NGP-4X is the higher-density option, with 40 Gigabit PoE+ ports, eight 5G-capable PoE+ ports, four 10G uplinks, and a 740W PoE budget. CBS350-12NP-4X provides 12 5G-capable PoE+ ports, four 10G uplinks, and 375W PoE. It is better aligned to compact multigigabit access blocks where rack space or endpoint count is lower.
Cisco CBS350-12NP-4X may be sourced as new, surplus, or refurbished hardware depending on market availability and region-specific suffixes such as -UK, -EU, or -NA. ORM Systems can quote the available condition at order time. Refurbished units are often attractive where Cisco channel availability is limited after end-of-sale milestones.
Buyers should request a current CBS350-12NP-4X price because condition, country suffix, lead time, quantity, and market availability affect the final quote. The most useful pricing request includes the required suffix, preferred condition, delivery country, target quantity, and any optics or DAC cables needed for the 10G SFP+ uplinks.
Cisco has announced end-of-sale milestones for select Cisco Business 350 models, and the notice lists country-suffix versions of CBS350-12NP-4X with a last order date of May 30, 2024. The same Cisco notice states that no migration product is currently available for those CBS350-12NP-4X variants. Buyers should confirm the exact regional PID before ordering.
Lead time for CBS350-12NP-4X depends on available stock, condition, region suffix, and whether the order includes SFP+ optics, DAC cables, or rack accessories. Because Cisco Business products are ordered through distributors and partners rather than directly from Cisco, reseller availability is the practical factor that determines dispatch timing.
Bulk pricing is commonly requested for CBS350-12NP-4X when teams refresh multiple closets or standardize branch access designs. Quantity, condition mix, region suffix, and accessory requirements influence the discount structure. A useful bulk request lists the number of switches, required power-region suffix, warranty expectation, and matching SFP+ or DAC uplink parts.
ORM Systems supplies warranty coverage for eligible CBS350-12NP-4X orders, with the term confirmed against condition, availability, and quotation details. Cisco lists the Business 350 Series with a limited lifetime warranty and next-business-day advance replacement where available, while reseller warranty terms apply to the specific new, surplus, or refurbished unit supplied.
Refurbished CBS350-12NP-4X units should be tested before dispatch for power-on operation, port link behavior, PoE delivery, management access, firmware status, fan operation, and physical condition. Testing is especially important on this model because buyers rely on 12 multigigabit PoE+ ports, four 10G uplinks, and a 375W PoE budget.
Cisco lists Business 350 Series certifications including UL 62368, CSA 22.2, CE mark, and FCC Part 15 Class A. The series also supports IPv6 features and has USGv6 and IPv6 Gold certification. CBS350-12NP-4X also follows networking standards such as 802.1Q, 802.1X, 802.3af, 802.3at, and 802.3az.
CBS350-12NP-4X is configured through the built-in web interface, Cisco Business mobile app, Cisco Business Dashboard, CLI, or Cisco Network Plug and Play. A typical first-use setup assigns management IP details, updates firmware where required, creates VLANs, configures PoE budgets, sets 10G uplinks, enables security controls, and saves the running configuration.
CBS350-12NP-4X does not require a separate feature license for the standard Cisco Business 350 switching, routing, PoE, management, and stacking functions listed by Cisco. Administrators should still download the correct firmware and documentation for the switch family, then confirm any support contract or warranty entitlement attached to the purchased unit.
Cisco lists package contents for Business 350 switches as the switch, power cord, mounting kit, and quick start guide. Minimum requirements include a supported web browser, Category 5e Ethernet cable, TCP/IP, a network adapter, and a client operating system. Buyers should add suitable SFP+ optics or DAC cables for the 10G uplinks.
UK buyers can purchase CBS350-12NP-4X through ORM Systems with the correct country or region suffix, commonly CBS350-12NP-4X-UK where that suffix is required. A complete purchasing request should specify new or refurbished condition, quantity, destination postcode, required warranty cover, and any 10G SFP+ optics or direct attach cables.
ORM Systems supports international B2B supply for Cisco hardware, including CBS350-12NP-4X, subject to availability, export requirements, destination, and the correct country or region suffix. International buyers should specify delivery country, plug or power-cord needs, condition preference, quantity, and whether matching SFP+ optics or DAC cables should ship with the switch.
