CBS350-48XT-4X is a high-density Cisco Business 350 Series managed Layer 3 switch built for 10 Gigabit Ethernet aggregation in small and midsize business networks. It provides 52 fixed data ports: 48 x 10G copper RJ-45 access ports for servers, storage nodes, Wi-Fi infrastructure, and high-speed workstations, plus 4 x 10G SFP+ uplinks for fiber or DAC connectivity. The platform is Non-PoE, rack-mountable, and designed as a fixed-configuration switch rather than a modular chassis. Hardware stacking support places it with the higher-capacity models in the same series. Compared with the CBS350-24XT sibling, which provides 20 x 10G copper ports plus 4 x 10G copper/SFP+ combo ports, this model provides 48 x 10G copper ports plus 4 fixed 10G SFP+ ports.
1,040 Gbps switching capacity supports nonblocking movement across the 10G copper edge and fixed SFP+ uplinks. 755.81 Mpps forwarding rate keeps packet handling aligned with high-throughput server, NAS, backup, and virtualization traffic. RIP v2, IPv4 static routing, IPv6 routing, Layer 3 interfaces, DHCP relay, UDP relay, and Policy-Based Routing let the platform segment VLANs and forward traffic without pushing every internal path through an upstream router. CBS350-48XT-4X also includes 512 MB DRAM, 256 MB flash, an 800 MHz ARM processor, and a 10 MB dynamically shared packet buffer for control-plane and forwarding support. STP/RSTP/MSTP, LACP, VLAN, RSPAN, sFlow, ACL, 802.1X, DHCP snooping, IP Source Guard, and Dynamic ARP Inspection add switching, monitoring, and access-control depth. Management options include web UI, Textview CLI, SNMP, SSH, HTTPS, Cisco Business Dashboard integration, Cisco Network Plug and Play, an RJ-45 console port, a USB Type-A slot, and dedicated Gigabit Ethernet out-of-band management.
CBS350-48XT-4X fits SMB distribution, aggregation, or top-of-rack deployments where 10G copper servers, storage systems, workstation clusters, wireless controllers, and firewall uplinks need dense local switching. Hardware stacking supports up to 4 units, allowing expansion under one management plane, while the 1U rack-mount form factor preserves cabinet space in wiring closets, server rooms, and compact edge racks. ORM Systems supplies this switch in new and certified refurbished condition, with refurbished units checked for 10G copper port health, SFP+ uplink function, stack readiness, management access, and stable operation under business network workloads.

CBS350-48XT-4X sits at the server access layer and terminates up to 48 copper 10 Gigabit Ethernet links from rack servers, storage appliances, and high-performance workstations. Engineers segment workloads with VLANs, combine parallel links through LACP, and apply Layer 2 security controls at each attachment point. Four dedicated 10G SFP+ ports carry fiber connections toward the aggregation tier without consuming the copper server interfaces. The design consolidates dense 10GBASE-T access into one rack unit while preserving distinct optical paths for upstream traffic.
CBS350-48XT-4X operates as a distribution switch for multiple 10G copper access links and hands aggregated traffic to upstream infrastructure through four dedicated 10G SFP+ interfaces. Network teams configure 802.1Q trunks, LACP groups, inter-VLAN routing, RIP v2, or static routes according to the topology, while the 1,040 Gbps switching fabric maintains nonblocking forwarding. SFP-10G-SR or SFP-10G-LR optics align each fiber path with the installed plant. The result is a defined copper-to-fiber boundary with routing and segmentation close to connected access domains.
Up to four compatible Cisco Business 350 switches form a hardware stack when operations require one configuration and management plane across an expanded switching block. CBS350-48XT-4X contributes 48 copper 10G ports, four dedicated SFP+ interfaces, and a separate Gigabit out-of-band management port per unit. Engineers standardize stack mode, firmware, VLANs, cross-stack link aggregation, and failover behavior before production handover. Cisco Business Dashboard, the web interface, CLI, and SNMP support ongoing administration. The topology gains centralized control, coordinated failover, and fewer independently managed switching nodes.

Cisco CBS350-48XT-4X is a rack-mountable, stackable managed switch in the Cisco Business 350 family. It provides 48 dedicated 10 Gigabit copper ports, four dedicated 10G SFP+ ports, and one separate Gigabit Ethernet out-of-band management port. The model targets high-density 10GBASE-T access, server connectivity, and aggregation deployments requiring Layer 2 and Layer 3 controls.
The CBS350 portion identifies Cisco's Business 350 managed-switch family. The 48XT-4X designation corresponds to this model's 48 copper 10 Gigabit Ethernet interfaces and four dedicated 10G SFP+ interfaces. Regional orderable part numbers add a suffix such as UK, EU, NA, or SP, so buyers should confirm the full regional SKU and included power cord when ordering.
CBS350-48XT-4X is a fixed-configuration Ethernet switch, not a router, firewall, or PoE injector. It uses managed Layer 2 switching and Layer 3 routing functions to connect and segment Ethernet devices. Its copper interfaces support 10 Gigabit access, while its SFP+ interfaces accept supported optics or direct-attach cables for fiber and short-range inter-switch links.
CBS350-48XT-4X sits at the high-density copper end of the Cisco Business 350 10 Gigabit range. It carries more 10GBASE-T interfaces than CBS350-8XT, CBS350-12XT, or CBS350-24XT and retains four dedicated SFP+ ports. This port mix suits buyers needing many copper 10G attachments rather than the fiber-heavy layouts of CBS350-24XS or CBS350-24XTS.
CBS350-48XT-4X provides 48 dedicated 10G copper ports, four dedicated 10G SFP+ ports, and one separate Gigabit Ethernet out-of-band management port. It also includes an RJ45 console port and a front-panel USB Type-A slot for file and image management. The SFP+ ports are not shared combo ports on this model.
CBS350-48XT-4X delivers 1,040 Gbps of switching capacity and a forwarding rate of 755.81 million packets per second using 64-byte packets. Cisco specifies the platform as wire-speed and nonblocking. Those figures reflect the full 48-port 10G copper and four-port 10G SFP+ architecture, making capacity planning straightforward for dense east-west and uplink traffic.
CBS350-48XT-4X does not provide PoE, PoE+, or PoE++ power on its 10GBASE-T ports. Connected access points, cameras, phones, or other powered devices therefore require their own power supplies or suitable external injectors. The non-PoE design is best aligned with servers, storage systems, workstations, and network appliances that already receive independent electrical power.
CBS350-48XT-4X supports managed Layer 2 and Layer 3 operation. Layer 2 functions include 802.1Q VLANs, RSTP, MSTP, LACP, private VLANs, and IGMP snooping. Layer 3 functions include wire-speed IPv4 and IPv6 routing, static routes, RIP v2, policy-based routing, DHCP server and relay functions, and routed physical, LAG, VLAN, or loopback interfaces.
CBS350-48XT-4X supports a built-in browser interface, a full command-line interface, Cisco Business Dashboard, Cisco Network Plug and Play, and SNMP versions 1, 2c, and 3. A dedicated Gigabit out-of-band management port separates administrative access from production interfaces. HTTPS, SSH, console access, syslog, and supported MIBs give network teams several operational integration choices.
CBS350-48XT-4X supports true hardware stacking with up to four units managed as one system. Cisco documents active and standby stack control, hardware failover, cross-stack link aggregation, ring and chain topologies, and hot-swappable stack members. Exact native or hybrid stack mode depends on the participating CBS350 product IDs, so firmware and stack-mode compatibility should be validated before deployment.
CBS350-48XT-4X is used for dense 10GBASE-T server access, high-performance workstation connectivity, storage appliance attachment, and copper-to-fiber aggregation. Forty-eight copper 10G interfaces concentrate local device links, while four dedicated SFP+ ports carry trunks or routed connections upstream. VLANs, LACP, access controls, and Layer 3 routing place segmentation and traffic handling close to attached systems.
CBS350-48XT-4X fits a branch, commercial server room, lab, or growing network that needs dozens of 10G copper connections in one rack unit. Its 1,040 Gbps switching capacity and four-unit stacking suit dense local traffic. Smaller deployments with fewer 10G links may fit CBS350-8XT, CBS350-12XT, or CBS350-24XT more economically.
CBS350-48XT-4X suits virtualization hosts, backup systems, media workflows, engineering workstations, network storage, and other data-heavy endpoints using 10GBASE-T. LACP supports multi-link connections, while VLANs and Layer 3 interfaces separate workload groups. The switch does not supply endpoint power, so the best-fit workloads use servers and appliances with independent power and compatible Ethernet adapters.
CBS350-48XT-4X works as a compact distribution or aggregation switch when downstream systems connect over 10G copper and upstream paths use 10G SFP+. Static routes, RIP v2, policy-based routing, VLAN interfaces, and LACP support segmented handoffs. The four dedicated SFP+ ports limit the number of independent fiber uplinks, so topology and redundancy requirements should be mapped before purchase.
CBS350-48XT-4X integrates with Cisco Business Dashboard through its embedded probe and supports Cisco Network Plug and Play for provisioning. Standards-based monitoring and control include SNMP v1, v2c, and v3, syslog, SSH, HTTPS, and a full CLI. These interfaces connect the switch with common network-management, logging, authentication, and automation workflows without requiring a Cisco DNA subscription.
Cisco documents SFP-10G-SR, SFP-10G-LR, SFP-10G-SR-S, SFP-10G-LR-S, and SFP-10GBase-T among supported 10G modules for CBS350 XG interfaces. Supported passive direct-attach choices include SFP-H10G-CU1M, SFP-H10G-CU3M, and SFP-H10G-CU5M. Buyers should verify current firmware, required reach, fiber type, connector requirements, regional availability, and Cisco's compatibility matrix before finalizing optics.
The 48 copper interfaces use 10GBASE-T Ethernet and should be paired with standards-compliant twisted-pair cabling matched to link distance. Category 6A is the usual choice for 10 Gigabit operation up to 100 metres, while shorter installed links require engineering validation. The four SFP+ ports use compatible 10G optics with appropriate multimode or single-mode fiber, or supported SFP+ direct-attach cables.
CBS350-48XT-4X carries standards-based Ethernet traffic from Cisco Business wireless access points, Cisco IP phones, routers, and other VLAN-aware devices. It supports 802.1Q VLANs, LLDP-MED, QoS, 802.1X, and RADIUS integration. Because this SKU is non-PoE, connected Cisco access points or phones require external power, a separate PoE switch, or correctly rated injectors.
CBS350-48XT-4X provides 48 dedicated 10G copper ports plus four dedicated 10G SFP+ ports, while CBS350-24XT provides 20 dedicated 10G copper ports and four copper or SFP+ combo ports. Their switching capacities are 1,040 Gbps and 480 Gbps respectively. Buyers needing maximum copper density should select the 48-port model; smaller racks may favour CBS350-24XT.
CBS350-48XT-4X is copper-focused with 48 dedicated 10GBASE-T ports and four dedicated SFP+ ports. CBS350-24XS is fiber-focused with 20 dedicated 10G SFP+ ports plus four copper or SFP+ combo interfaces. Both support CBS350 management and stacking features, but procurement should follow the installed media plant, port-density requirement, optic budget, and server network-interface type.
CBS350-48XT-4X offers 48 dedicated 10G copper ports and four dedicated SFP+ ports, whereas CBS350-24XTS splits its 24 interfaces evenly between 12 copper 10G ports and 12 dedicated SFP+ ports. Each model has a separate Gigabit management interface. The 48XT-4X suits dense copper racks; the 24XTS better balances copper and fiber attachments.
CBS350-48XT-4X supplies 48 copper 10G ports, four 10G SFP+ ports, 1,040 Gbps switching capacity, and 755.81 mpps forwarding. CBS350-48T-4X supplies 48 Gigabit copper ports, four 10G SFP+ ports, 176 Gbps capacity, and 130.94 mpps forwarding. The XT model targets 10G endpoint density, while the T model reduces cost for Gigabit access.
CBS350-48XT-4X may be sourced in new or certified refurbished condition through ORM Systems, subject to live inventory and regional variant. Buyers should specify quantity, condition preference, delivery country, power-cord region, optics, cables, and warranty requirement. Because Cisco has ended sale of this SKU, refurbished and secondary-market supply may be more practical than factory-new availability.
CBS350-48XT-4X pricing is provided by quotation because condition, quantity, regional suffix, warranty, optics, cables, destination, and current supply affect the final amount. A comparable quote should identify the exact switch SKU and separate any SFP+ modules or direct-attach cables. ORM Systems can price new and certified refurbished sourcing paths when available.
CBS350-48XT-4X is covered by Cisco's end-of-sale announcement for selected CBS350 models. The last Cisco order date was October 29, 2024, and the last date of support is October 31, 2029. Cisco's notice lists no current migration product for this exact 48-port 10G copper model, so lifecycle planning should accompany any purchase.
Lead time for CBS350-48XT-4X is confirmed during quotation because stock condition, regional SKU, order quantity, testing, warranty preparation, and destination all affect fulfilment. End-of-sale status makes current inventory especially important. Buyers should provide the required delivery date, country, condition preference, and complete optic or cable list so the quoted schedule reflects the full bill of materials.
Bulk pricing is available by quotation for CBS350-48XT-4X when multiple units are required. Quantity, new or refurbished condition, regional power requirements, optic selection, stack cabling, warranty term, and shipping destination determine the commercial offer. A single consolidated bill of materials helps ORM Systems align unit pricing, testing, accessories, and delivery dates across the full order.
ORM Systems offers up to a three-year warranty on eligible new and certified refurbished enterprise hardware, including qualifying Cisco switches. Coverage for CBS350-48XT-4X should be confirmed on the quotation because condition, sourcing route, region, and service level may affect terms. Cisco also originally supplied CBS350 switches with a limited lifetime hardware warranty subject to Cisco's warranty conditions.
Certified refurbished CBS350-48XT-4X units receive switch-class functional checks before dispatch. Testing covers boot and firmware status, all 48 copper 10G ports, the four SFP+ interfaces, out-of-band management, console access, fans, power supply, stack readiness, configuration reset, and physical condition. The final quotation should identify included accessories and the applicable warranty.
Cisco lists UL 62368, CSA 22.2, CE marking, and FCC Part 15 Class A certification for the CBS350 family. The series also supports IEEE Ethernet, VLAN, spanning-tree, and link-aggregation standards and has completed IPv6 testing associated with USGv6 and IPv6 Gold certification. Buyers should confirm any destination-specific regulatory, import, and environmental requirements before deployment.
First-use configuration starts with rack installation, AC power, a management or console connection, and access through the web interface or RJ45 console. Administrators then set secure credentials, management addressing, time, firmware, VLANs, trunks, routing, monitoring, and backup configuration. Copper link speed, SFP+ recognition, stack settings, and out-of-band reachability should be validated before production traffic is introduced.
CBS350-48XT-4X does not require a Cisco software licence or subscription for its switch features. Cisco states that Cisco Business switch functionality is available with the hardware purchase. Optional support arrangements, reseller warranty coverage, and Cisco Business Dashboard licensing above its included device allowance are separate commercial considerations and should not be confused with a switch feature licence.
CBS350-48XT-4X requires a compatible regional AC power cord, suitable rack hardware, and 10GBASE-T cabling for copper links. Fiber connections require supported SFP+ transceivers and matching fiber patch leads, while short interconnects may use supported SFP+ direct-attach cables. Stack designs also require compatible CBS350 members, aligned firmware and stack modes, and appropriately planned 10G stack interconnects.
CBS350-48XT-4X can be sourced through ORM Systems for UK commercial and enterprise hardware procurement, subject to availability. Buyers should request the exact UK or appropriate regional part number and state quantity, condition, optics, stack cables, power cords, delivery date, and warranty needs. A formal quote confirms current stock, price, lead time, and included accessories.
ORM Systems supports international shipment of enterprise hardware, including CBS350-48XT-4X where stock and destination rules permit. International buyers should provide the delivery country, quantity, condition preference, regional power requirement, optic and cable list, and warranty expectation. The quotation can then confirm shipping method, estimated transit, insurance, customs documentation, duties treatment, and any destination-specific compliance requirements.
