CBS350-12NP-4X-EU provides twelve multigigabit PoE+ access ports supporting 100M, 1G, 2.5G, and 5G connections for powered network endpoints. This managed Layer 2+ switch has four fixed 10G uplinks: two dedicated SFP+ connections and two copper/SFP+ combo connections, with each combo connection using one medium at a time. Eight access ports also support 60W PoE for higher-draw equipment. The Cisco Business 350 Series places this configuration in small-business networks connecting wireless access points, phones, surveillance equipment, and other office devices. Its rack-mount 1U chassis uses an internal AC supply and three fans. The sibling CBS350-24NGP-4X-EU provides twenty-four access ports where a larger endpoint count is required. A removable uplink module is not part of this configuration; uplink connections use the built-in interfaces.

200 Gbps switching capacity accommodates the fixed access and uplink interfaces without requiring an additional network card. 148.8 Mpps forwarding performance is specified for 64-byte packets. 375W of shared PoE allocation requires endpoint power requests to be sized together rather than treating each port's power capability as a simultaneous entitlement. Static routing, RIP v2, and PBR provide inter-VLAN and next-hop control without an enterprise routing license tier. CBS350-12NP-4X-EU carries 512 MB of DRAM and 256 MB of flash for its management software and stored configuration. A dynamically shared 3 MB packet buffer serves traffic across the interfaces. Browser administration, the CLI, and SNMP provide local and remote configuration paths within the Cisco Business portfolio. STP, RSTP, and MSTP handle switching topology control, while LACP supports aggregated connections. The USB Type-A interface supports file and image management without using a network uplink for the transfer.
ORM Systems supplies CBS350-12NP-4X-EU new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units; Cisco's separate limited lifetime coverage ends at the May 31, 2029 support boundary. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, PoE output under load on every powered port, optics bay recognition, PSU and fan status; firmware is verified and configuration wiped to factory default. Specify condition and connection accessories on the purchase order; every condition includes 30-day returns, with terms applying. POs are accepted, government buyers have Net-30 terms, and volume requirements can use UK, EU, US, and MEA stock and RMA coverage with advance replacement.

Replaces | SG350X-12PMV-K9-EU / end of sale July 30, 2022 |
An installed SG350X-12PMV-K9-EU fleet reaching its replacement cycle creates a part-number migration requirement rather than a general capacity expansion. That model reached end of sale on July 30, 2022. Before the purchase order, specify the replacement PID, required condition, and connection accessories for the existing cabling.
An acceptance lab requiring packet captures before deployment can mirror traffic from 8 source ports to one destination port. The capture connection needs to match the analyzer interface, while the monitoring configuration remains separate from production settings. Specify the capture connection and staging requirements before ordering.
A branch rollout using Cisco Network Plug and Play can include switch provisioning through Cisco PnP Connect. The embedded Cisco Business Dashboard probe removes the requirement for a separate probe appliance or virtual machine at the location. Confirm the provisioning workflow and dashboard arrangement before issuing the purchase order.
10G on every access port
The twelve access ports stop at 5G; 10G connections are confined to the fixed uplinks. A requirement for twelve native 10G access connections exceeds this configuration.
More than 60W per endpoint
Eight powered ports support 60W PoE, but no access port provides a higher per-port allocation. Endpoints requiring more than 60W cannot receive that power from this switch.
New security maintenance releases
Security maintenance ended on May 30, 2025, so new planned security remedies are no longer available. No migration successor is named for this configuration.

CBS350-12NP-4X-EU identifies a Cisco Business 350 managed switch with twelve multigigabit powered access ports and four 10G uplinks. CBS350 identifies the family, 12 identifies the access-port count, NP identifies the powered multigigabit configuration, and 4X identifies the uplink configuration. EU is the regional ordering suffix, not a software license tier.
CBS350-12NP-4X-EU supports a web interface over HTTP or HTTPS, CLI access through the RJ-45 console or SSH and Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. The embedded dashboard probe avoids a separate probe appliance, while Cisco Network Plug and Play provides an additional provisioning path.
CBS350-12NP-4X-EU reached end of sale on May 30, 2024, and has a last date of support of May 31, 2029. Software maintenance, planned security remedies, and included phone support ended on May 30, 2025. No migration successor is named for this particular model, so remaining service entitlement does not include continuing software development.
ORM Systems offers CBS350-12NP-4X-EU new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Both conditions include 30-day returns; terms apply. Cisco's separate limited lifetime warranty is bounded by May 31, 2029, the last date of support.
CBS350-12NP-4X-EU is the named replacement for SG350X-12PMV-K9-EU, a twelve-port 5G PoE stackable managed switch. The predecessor reached end of sale on July 30, 2022. This replacement relationship identifies the migration part number; it does not make the newer model current, because its own end-of-sale milestone has also passed.
CBS350-12NP-4X-EU provides a shared 375W PoE allocation across twelve powered access ports, with eight ports supporting 60W PoE. Eight simultaneous 60W requests would total 480W, exceeding that allocation. Endpoint power requirements therefore need to be assessed together rather than assuming every high-power port can receive its maximum concurrently.
The Business 350 twelve-port 5G PoE+ switch has two dedicated 10G SFP+ uplinks and two 10G copper/SFP+ combo uplinks. Each combo uses either its copper connection or its SFP+ connection. Supported fiber choices include SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber; select optics against the installed fiber and distance.
Yes, CBS350-12NP-4X-EU supports hardware stacking with four members managed as one system. Stack interconnections use 10G interfaces rather than dedicated rear stacking ports. Ring and chain arrangements are supported, and the stack provides active and standby control. Allocate the required interfaces and connection accessories before finalizing the uplink arrangement.
The Business 350 Series supports IPv4 static routing, RIP v2, and PBR, with 990 static routes and 128 IP interfaces. Routing interfaces can be associated with physical ports, link aggregations, VLANs, or loopbacks. This combination is Layer 2+ here; the static-route allowance is not an additional dynamic-routing scale figure.
CBS350-12NP-4X-EU uses an internal universal AC supply accepting 100-240V AC at 50-60 Hz. Worst-case consumption including PoE is 494.5W at 110V or 476.4W at 220V. Those input figures include switch operation and powered endpoints; the separate 375W PoE allocation is not the total AC draw.
CBS350-48NGP-4X-EU provides a 740W PoE allocation, while CBS350-12NP-4X-EU provides 375W. Both allocations are shared rather than guaranteed simultaneous maximum power on every port. The twelve-port configuration addresses a smaller powered-endpoint requirement; the forty-eight-port configuration combines greater endpoint density with a larger aggregate power allocation.
CBS350-12NP-4X-EU has four 10G uplinks, while CBS350-8MP-2X-EU has two 10G combo uplinks. The four-uplink configuration includes two dedicated SFP+ interfaces in addition to its combo connections. Buyers requiring more uplink connections need the four-uplink arrangement; a requirement limited to two connections can use the smaller uplink configuration.
CBS350-24NGP-4X-EU provides twenty-four access ports, whereas CBS350-12NP-4X-EU provides twelve access ports. That distinction concerns endpoint density rather than an additional uplink module or subscription option. A twelve-endpoint purchase fits the smaller configuration; an order requiring more physical access connections needs the twenty-four-port arrangement to accommodate the endpoint count.
The Business 350 twelve-port multigigabit switch is rack-mountable in a 1U chassis and is not fanless; it has three fans. Its dimensions are 440 mm wide, 257 mm deep, and 44 mm high, with a weight of 4.24 kg. Account for powered cooling rather than treating this model as a silent desktop switch.
