CBS350-12XS is a Cisco Business 350 Series managed Layer 3 switch built for compact 10 Gigabit Ethernet fibre aggregation. It provides 10 dedicated 10G SFP+ ports, 2 fixed 10G RJ-45/SFP+ combo ports, and a separate Gigabit Ethernet out-of-band management port for administration. The port layout suits SFP+ optics, DAC cables, and selective copper 10G handoff without using an empty modular uplink bay. PoE is not present, so the switch targets data transport rather than powered endpoint access. Its fixed fibre orientation distinguishes it from Gigabit access models that prioritize endpoint density or PoE budgets. The rack-mount 1U chassis belongs to the Cisco Business 350 Series, a small business managed switching family with dashboard, CLI, SNMP, Layer 3, and stacking functions. CBS350-12XT is the closest sibling, differing by using 10 dedicated 10G copper ports instead of 10 dedicated 10G SFP+ ports.
240 Gbps switching capacity carries the active 10G port set at wire speed for aggregation links, storage paths, and server access traffic. 178.56 Mpps forwarding rate supports high packet-rate flows across VLAN trunks and routed interfaces. No PoE budget applies because this switch has no powered access ports, which keeps the platform focused on fibre and copper transport. RIP v2 dynamic routing, IPv4 static routes, IPv6 routing, Layer 3 interfaces, CIDR, PBR, DHCP relay, and UDP relay support routed segmentation between local VLANs. STP/RSTP/MSTP, LACP, VLAN translation, Q-in-Q, IGMP snooping, ACLs, QoS queues, jumbo frames, and iSCSI optimization shape traffic across mixed storage and user networks. CBS350-12XS includes 512 MB DRAM, 256 MB flash, a 3 MB packet buffer, and a 16000-entry MAC table. Management teams use Cisco Business Dashboard, web UI, CLI, SNMP v1/v2c/v3, SSH, RADIUS, TACACS+, RMON, sFlow, and Cisco Network Plug and Play for configuration, monitoring, authentication, and deployment control.
CBS350-12XS operates at the SMB access, aggregation, or server-edge tier where access switches, firewalls, routers, NAS appliances, virtualization hosts, and 10G copper devices meet fibre uplinks. Hardware stacking supports up to 4 Cisco Business 350 units as one managed system, while the 1U rack format keeps the switch aligned with standard cabinet builds. The 440 mm chassis width and 44 mm height suit cabinet layouts that reserve one rack unit for aggregation rather than endpoint switching. ORM Systems supplies this switch new and certified refurbished, and refurbished units are checked for SFP+ recognition, combo-port operation, management access, fan health, and stable forwarding before dispatch. Request current pricing from ORM Systems for the switch, matching optics, DAC cables, and regional power requirements. ORM Systems also aligns region-specific suffixes such as -UK, -EU, and -NA with destination requirements. Volume buyers receive procurement support for multi-site quantities, spare units, warranty cover, and compatible transceiver bundles.

CBS350-12XS sits at the top of a compact server rack and terminates 10G SFP+ links from virtualization hosts, NAS systems, and backup appliances. Engineers place storage, hypervisor, and management VLANs on the dedicated SFP+ ports, then reserve the 2 copper/SFP+ combo ports for a firewall, router, or copper 10G handoff. LACP groups carry paired server links where resilience is required. The rack gains a managed 10G access point with predictable fibre density and isolated management reachability, keeping troubleshooting scoped to that rack.
CBS350-12XS operates between access switches and the distribution layer when several downstream closets present 10G SFP+ uplinks. Network teams configure tagged trunks, routed interfaces, or LACP bundles across the 10 dedicated SFP+ ports, then use the combo ports for local copper or optical distribution links. The 240 Gbps switching fabric keeps uplink aggregation nonblocking for this 12-port design. The network gains a compact aggregation tier that reduces 10G uplink sprawl at the distribution switch while preserving clear distribution port assignments.
CBS350-12XS joins a Cisco Business 350 stack when operations teams need more 10G SFP+ ports under one management address. Administrators align firmware, stack roles, VLAN databases, QoS policies, and monitoring profiles across compatible stack members, then manage the added fibre ports through Cisco Business Dashboard, CLI, or SNMP. The out-of-band GE management port keeps administrative access separate from production uplinks. The site gains expanded 10G capacity without creating another standalone management island during refresh work, closet growth, and maintenance windows.

The Cisco CBS350-12XS is a Cisco Business 350 Series managed 10 Gigabit Ethernet switch for fibre-heavy network access, aggregation, and server connectivity. It provides 10 dedicated 10G SFP+ ports, 2 additional 10G copper/SFP+ combo ports, and a Gigabit Ethernet out-of-band management port in a rack-mountable chassis for managed small business and commercial networks.
CBS350-12XS identifies a Cisco Business 350 Series switch with 12 active 10G switching ports based on SFP+ connectivity. The XS designation points to a 10 Gigabit SFP+ focused model, while the hardware also includes 2 10G copper/SFP+ combo interfaces. CBS350-12XS is ordered with a country or region suffix such as -UK, -EU, or -NA.
CBS350-12XS is a Layer 2 and Layer 3 managed Ethernet switch, not a router, firewall, or optical transceiver. It terminates SFP+ fibre or DAC links, supports managed switching features such as VLANs, LACP, QoS, and access control, and fits into a 1U rack position where 10G port density is required.
CBS350-12XS sits in the Cisco Business 350 managed switch range, above basic unmanaged and smart switch options because it supports advanced management, Layer 3 traffic handling, and true stacking. Within the 350 10 Gigabit models, it is the compact SFP+ focused 12-port option, alongside copper, mixed copper/SFP+, and higher-density 24-port variants.
Cisco CBS350-12XS provides 10 dedicated 10G SFP+ ports, 2 10G copper/SFP+ combo ports, and 1 Gigabit Ethernet out-of-band management port. Each combo port has one copper Ethernet interface and one SFP or SFP+ slot, with one side active at a time. The switch is therefore designed around 12 active 10G switching ports.
CBS350-12XS supports 240 Gbps switching capacity and 178.56 million packets per second forwarding rate with 64-byte packets. Cisco lists the Business 350 switches as wire-speed and nonblocking, which makes the model suitable for dense 10G fibre or DAC aggregation where oversubscription must be controlled at the access or distribution edge.
CBS350-12XS does not provide PoE because its access ports are 10G SFP+ and 10G copper/SFP+ combo interfaces rather than powered RJ-45 endpoint ports. Buyers that need Cisco Business 350 PoE should compare PoE models such as CBS350-24P-4X, CBS350-24FP-4X, or CBS350-48FP-4X, depending on endpoint count and PoE budget.
CBS350-12XS supports managed Layer 2 switching features such as VLANs, 802.1Q tagging, Spanning Tree, Rapid Spanning Tree, Multiple Spanning Tree, and LACP link aggregation. The Cisco Business 350 Series also provides advanced Layer 3 traffic management, including dynamic Layer 3 routing for inter-VLAN segmentation without pushing every internal route back to an upstream router.
CBS350-12XS is managed through Cisco Business Dashboard, embedded probe capability, web user interfaces, a full command-line interface, SNMP, and Cisco Network Plug and Play workflows. The switch also includes a dedicated Gigabit Ethernet out-of-band management port, allowing administration traffic to remain separate from the 10G production switching interfaces.
Cisco CBS350-12XS supports true stacking as part of the Cisco Business 350 Series. A stack is configured, managed, and troubleshot as a single unit with one IP address, while the stack operates across data, control, and management planes. This matters when multiple 10G access or aggregation switches need unified administration.
CBS350-12XS is used for 10G fibre aggregation, server access, storage network handoff, and high-speed uplinks between access and distribution layers. Its 10 dedicated SFP+ ports suit optical modules or DAC cables, while the 2 copper/SFP+ combo ports provide selective RJ-45 handoff where a nearby 10GBASE-T device must remain connected.
CBS350-12XS fits small and midsize commercial networks that need managed 10G connectivity without moving to a large chassis or high-port-count aggregation switch. Its 1U rack-mountable design, 240 Gbps switching capacity, and 12 active 10G ports suit wiring closets, compact server rooms, and network rooms where fibre uplinks outnumber copper endpoints.
Cisco CBS350-12XS suits workloads that benefit from multiple 10G links, including virtualization hosts, NAS or SAN access, backup networks, video production storage, high-speed workstation uplinks, and inter-switch aggregation. The switch does not power endpoints, so it is a stronger fit for SFP+ transport and server-side connectivity than for IP phones or access points.
CBS350-12XS works well as a compact aggregation switch when downstream access switches, servers, or storage devices present 10G SFP+ uplinks. Network teams use VLAN trunks, LACP groups, routed interfaces, and ACLs to consolidate traffic before handing it to a core router, firewall, or larger distribution switch.
Cisco lists supported modules for the Business 350 Series including MGBSX1, MGBLX1, MGBLH1, MGBT1, GLC-SX-MMD, GLC-LH-SMD, GLC-BX-U, GLC-BX-D, GLC-TE, SFP-H10GB-CU1M, SFP-H10GB-CU3M, SFP-H10GB-CU5M, SFP-10G-SR, SFP-10G-LR, SFP-10G-SR-S, and SFP-10G-LR-S. For CBS350-12XS, optics selection should match fibre type, reach, and speed.
CBS350-12XS includes 2 10G copper/SFP+ combo ports for connections to 10GBASE-T servers, firewalls, routers, or adjacent switches. Cisco notes that combo ports provide one copper Ethernet port and one SFP or SFP+ slot, with only one side active at a time. Copper cabling should follow the required category and distance for the connected device speed.
CBS350-12XS integrates with Cisco Business Dashboard, Cisco Business mobile workflows, Cisco Network Plug and Play, SNMP-based monitoring tools, CLI automation, RADIUS authentication, and Cisco Discovery Protocol. These options let network operations teams manage the switch directly, discover connected Cisco devices, and fold it into existing monitoring and configuration practices.
CBS350-12XS supports standards used in managed Ethernet networks, including 802.1Q VLAN tagging, 802.1X authentication, 802.3ad LACP, Spanning Tree variants, IPv4, IPv6, and Energy Efficient Ethernet 802.3az. It also supports security functions such as port security, DHCP snooping, Dynamic ARP Inspection, IP Source Guard, and IPv6 First Hop Security.
CBS350-12XS is the SFP+ focused 12-port 10G model, while CBS350-12XT is the copper focused sibling. CBS350-12XS provides 10 dedicated 10G SFP+ ports plus 2 copper/SFP+ combo ports. CBS350-12XT provides 10 dedicated 10G copper ports plus 2 copper/SFP+ combo ports, making it better where most connected devices use RJ-45 10GBASE-T.
CBS350-12XS provides more fibre-oriented 10G connectivity than CBS350-8XT. The CBS350-8XT has 6 dedicated 10G copper ports and 2 copper/SFP+ combo ports, while CBS350-12XS has 10 dedicated 10G SFP+ ports and 2 combo ports. CBS350-12XS is stronger for fibre aggregation, and CBS350-8XT is better for smaller copper 10G deployments.
CBS350-16XTS is the mixed 10G option with 8 dedicated copper ports and 8 dedicated SFP+ ports. CBS350-12XS concentrates on SFP+ connectivity with 10 dedicated SFP+ ports and 2 combo ports. Buyers choose CBS350-16XTS when copper and fibre 10G counts are balanced, and CBS350-12XS when fibre or DAC handoffs dominate.
CBS350-24XS is the higher-density SFP+ model with 24 10G SFP+ ports and 4 10G copper ports shared as combo interfaces. CBS350-12XS offers 12 active 10G ports in a smaller aggregation footprint. CBS350-24XS fits larger distribution blocks, while CBS350-12XS fits compact racks and smaller 10G aggregation designs.
CBS350-12XS may be sourced by ORM Systems in new, refurbished, or region-specific variants such as CBS350-12XS-UK, CBS350-12XS-EU, or CBS350-12XS-NA. Availability changes because Cisco has announced end-of-sale milestones for selected CBS350 models, so buyers should request a current quote for exact condition, stock, and replacement options.
CBS350-12XS price is affected by condition, region suffix, available stock, warranty term, optics or DAC bundles, and order quantity. Refurbished units usually price differently from new old stock, while complete deployments may also include SFP+ modules, rack accessories, console cables, and spares. ORM Systems can quote the switch with matching transceivers when required.
Cisco has announced end-of-sale and end-of-life milestones for selected Cisco Business 350 models, including CBS350-12XS regional part numbers. The Cisco-listed migration product for CBS350-12XS is C1300-12XS. Buyers maintaining an installed CBS350 network may still source replacement or expansion units through the reseller market where stock is available.
CBS350-12XS lead time depends on live new or refurbished stock, the required country suffix, testing requirements, and whether matching SFP+ optics or DAC cables are included. End-of-sale status can make supply more variable than current-run products. ORM Systems should confirm lead time at quotation so procurement teams can plan installation windows accurately.
Bulk pricing is commonly relevant for CBS350-12XS when several network rooms, stack members, or spare units are purchased together. ORM Systems can price quantity requirements alongside compatible SFP-10G-SR, SFP-10G-LR, or SFP-H10GB-CU DAC options. A consolidated quote helps buyers compare switch-only pricing against a deployment bundle with optics, cables, and warranty coverage.
CBS350-12XS purchases from ORM Systems can be supplied with warranty options suited to new or refurbished hardware, commonly up to 3 years where applicable. Warranty coverage should be confirmed on the quote because condition, source channel, and remaining manufacturer lifecycle status affect the exact terms. The switch should be ordered with documented warranty expectations before deployment.
Refurbished CBS350-12XS units should be tested before dispatch for boot health, firmware access, port status, SFP+ recognition, combo-port behaviour, management access, fan operation, and physical condition. Testing is especially important on a 10G aggregation switch because failed optics detection, noisy cooling, or unstable uplinks can disrupt server or distribution connectivity.
Cisco lists Business 350 Series certifications including UL 62368, CSA 22.2, CE mark, and FCC Part 15 Class A. The series also completed IPv6 testing and received USGv6 and IPv6 Gold certification. These compliance details support enterprise procurement checks where electrical safety, electromagnetic compatibility, and IPv6 readiness must be documented.
CBS350-12XS is first configured through the web interface, CLI, Cisco Business Dashboard workflows, or Cisco Network Plug and Play. Network teams normally connect the out-of-band management port or a management VLAN, assign addressing, update firmware where required, then configure VLANs, trunks, LACP groups, routing, authentication, and monitoring before production traffic moves onto the 10G ports.
CBS350-12XS does not require a separate Cisco DNA licence for its core managed switching operation. It belongs to the Cisco Business switch family rather than Catalyst enterprise licensing families. Buyers should still check firmware, support, and management requirements for their environment, especially when Cisco Business Dashboard, SNMP monitoring, or standardized software versions are part of deployment governance.
CBS350-12XS deployments usually require compatible SFP+ optics or DAC cables, fibre patch leads, rack mounting hardware, power cords for the target region, console access, and Cat6a or better cabling for 10G copper combo links. Design teams should also reserve management addressing, VLAN IDs, routing plans, and monitoring profiles before installing the switch.
UK buyers can purchase Cisco CBS350-12XS through ORM Systems as a new or refurbished business networking part, subject to live stock and regional suffix availability. The quote should specify whether the requested part is CBS350-12XS-UK, another acceptable country suffix, or a functional replacement such as C1300-12XS for new Cisco Business deployments.
ORM Systems can support international CBS350-12XS enquiries where export, regional power cord, warranty, and customs requirements are confirmed before dispatch. International buyers should include destination country, required condition, target delivery date, and any optics or DAC accessories in the quote request so the correct country suffix and shipping plan are priced.
