CBS350-12NP-4X-NA is a managed multigigabit PoE+ switch with 12 copper access ports supporting 100 Mbps, 1G, 2.5G, and 5G connections. Its Layer 2+ feature set combines switching with static routing and RIP v2. Four fixed 10G uplinks comprise two dedicated SFP+ ports and two copper/SFP+ combo ports; each combo connection uses either copper or fiber, not both simultaneously. Eight access ports support 60W PoE, subject to the shared power allocation. The rack-mount 1U chassis belongs to Cisco Business 350 and serves powered wireless, voice, and surveillance endpoints in small-business networks. The discontinued CBS350-48NGP-4X-NA offers a larger 740W PoE allocation for legacy installations with higher aggregate endpoint demand.
CBS350-12NP-4X-NA price for new stock is $2,233.35. CBS350-12NP-4X-NA refurb price is $1,836.00. CBS350-12NP-4X-NA is in stock and available for next-day dispatch. (terms applied)

200 Gbps switching capacity supports nonblocking operation across the installed interfaces, while 148.8 Mpps forwarding handles the published 64-byte packet workload. 375W of shared PoE power must cover the connected endpoint allocation rather than every port's individual maximum simultaneously. Static IPv4 and IPv6 routing, RIP v2, and PBR provide local traffic forwarding and next-hop control. The static-routing limit is 990 routes, with 128 IP interfaces available. CBS350-12NP-4X-NA carries 512 MB of DRAM and 256 MB of flash, while a 3 MB packet buffer is dynamically shared across the ports. A 16000-entry MAC table supports address learning, and 4094 simultaneous VLANs provide traffic separation. STP, RSTP, and MSTP control switching loops; LACP supports aggregated links. Cisco Business also provides eight hardware queues, ingress policing, and egress shaping for traffic handling. The 494.5W maximum draw with PoE is the relevant published figure for sizing the rack's electrical allocation.
ORM Systems supplies CBS350-12NP-4X-NA new sealed or certified refurbished; new orders carry up to a 3-year extended warranty, refurbished orders up to 1 year, and returns cover 30 days on every condition; terms apply. 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. Specify condition, quantity, required optics, and shipping region on the PO; Cisco's separate limited lifetime hardware warranty is bounded by the last date of support, May 31, 2029. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement across UK, EU, US, and MEA regional stock and RMA operations.

When replacing a discontinued SG350X-12PMV-K9-NA estate, the replacement relationship identifies this configuration for the existing purchase plan. The older model reached end of sale on July 30, 2022. Before issuing the PO, separate immediate hardware replacement requirements from the longer-term migration plan and confirm the required condition and quantity.
When replacement units need staging before installation, two firmware images and text-editable configuration files support an image-and-configuration preparation workflow. Define the approved firmware, management credentials, and configuration file separately from the hardware order. Record those staging requirements on the PO before the equipment enters the production change process.
10G speeds on copper access ports
Copper access connections stop at 5G; only the fixed uplinks provide 10G. A requirement for 10G on the powered access connections exceeds this configuration.
60W output across all twelve endpoints
Only eight access ports support 60W PoE, and their combined maximum exceeds the shared allocation. Twelve simultaneously powered 60W endpoints are not supported by this configuration.
Security patches throughout a new deployment
Security vulnerability support ended May 30, 2025. This discontinued configuration no longer receives planned security remedies, and no direct migration PID is assigned.

CBS350-12NP-4X-NA identifies a Cisco Business 350 managed switch: CBS350 is the family, 12 is the access-port count, NP identifies the multigigabit PoE+ configuration, and 4X identifies four 10G uplinks. NA selects the regional ordering variant for the United States, Canada, Mexico, Colombia, Chile, and other Latin American markets.
Cisco Business 350 supports a browser-based HTTP/HTTPS interface, CLI through the RJ-45 console or SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP. An embedded Dashboard probe supports centralized management without a separate probe appliance. Cisco Network Plug and Play also supports provisioning workflows.
CBS350-12NP-4X-NA provides a shared 375W PoE budget across 12 powered access ports, with eight ports supporting 60W PoE. Individual port capability does not mean every eligible port can draw its maximum together. Specify endpoint power requirements and their total allocation before placing the order.
CBS350-12NP-4X-NA has four fixed 10G uplinks: two dedicated SFP+ connections and two copper/SFP+ combo connections. Only one medium operates on each combo connection at a time. Supported fiber options include SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber; specify the required optics separately.
Four members is the hardware stack limit for CBS350-12NP-4X-NA. Cisco Business 350 stacking supports a unified system with active and standby control, using 10G fiber interfaces. Ring and chain arrangements are available, so the purchase plan must reserve connections and cabling for the chosen topology.
Cisco Business 350 supports static IPv4 and IPv6 routing, RIP v2 dynamic routing, and PBR. The static-routing allowance is 990 routes with 128 IP interfaces. Those limits should be checked against the planned local routing configuration rather than treated as an unrestricted routing scale for every protocol.
CBS350-12NP-4X-NA uses an internal 100-240V AC power supply and has a published maximum draw of 494.5W with PoE at 110V. The corresponding figure at 220V is 476.4W. Size the electrical allocation using the applicable input voltage and the consumption including powered endpoints.
CBS350-12NP-4X-NA replaces the discontinued SG350X-12PMV-K9-NA, whose end-of-sale date was July 30, 2022. The older model's last date of support is July 31, 2027. Replacement planning must also account for the CBS350 model's own discontinued status and the absence of an assigned migration PID.
CBS350-12NP-4X-NA reached end of sale May 30, 2024, and its last date of support is May 31, 2029. Software maintenance and security vulnerability support ended May 30, 2025. The model is discontinued, and Cisco has not assigned a migration product for this configuration.
ORM Systems offers CBS350-12NP-4X-NA new sealed or certified refurbished, with new coverage up to a 3-year extended warranty and refurbished coverage up to 1 year. Returns are available for 30 days on every condition; terms apply. Cisco's separate limited lifetime warranty includes next-business-day advance replacement where available, with eligible service ending May 31, 2029.
CBS350-12NP-4X-NA allocates 375W to PoE, whereas CBS350-48NGP-4X-NA provides 740W. Both models are discontinued without an assigned migration PID. For legacy capacity planning, the former allocation addresses lower aggregate endpoint demand, while the latter accommodates a larger total powered-device requirement within its shared budget.
