CBS350-24XS is a managed 10 Gigabit Ethernet fiber switch with 24 logical network ports for small-business networks: 20 dedicated SFP+ interfaces and four SFP+/copper combo connections. Each shared connection operates through either its fiber or copper side, not both simultaneously. Fixed interfaces accommodate fiber links and a limited number of copper attachments without purchasing an uplink card; the rack-mount 1U chassis uses an internal AC supply and does not deliver PoE. The Cisco Business 350 Series Managed Switches provide configurable switching and Layer 2+ routing capabilities rather than unmanaged connectivity. The discontinued CBS350-24XTS instead divides its network connections between twelve copper ports and twelve dedicated SFP+ ports. A separate Gigabit Ethernet out-of-band management interface keeps administrative connectivity distinct from network-facing connections.
CBS350-24XS price for new stock is $2,999.43, a 48.7% saving from the Cisco list price of $5,844.15. CBS350-24XS refurb price is $4,545.45. CBS350-24XS is in stock and available for next-day dispatch. (terms applied)

480 Gbps switching capacity provides the switching bandwidth for network traffic, while 240 Mpps forwarding rate is the packet-processing figure to use when sizing small-packet workloads. 990 IPv4 static routes support inter-VLAN routing, with RIP v2 available for dynamic route exchange and PBR for directing selected traffic toward different next hops. STP/RSTP/MSTP control switching loops, and LACP groups interfaces for aggregated connections. CBS350-24XS carries 512 MB of DRAM and 256 MB of flash, separating working memory from image storage. Its 3 MB aggregate packet buffer is dynamically shared across ports, while eight hardware queues support strict-priority and Weighted Round-Robin scheduling. The Cisco Business feature set accommodates 16000 MAC addresses and 4094 simultaneous VLANs for network segmentation. 39W worst-case consumption provides the maximum power figure for rack power planning. Four fans make passive, fanless cooling unavailable, and the 0°C to 50°C operating range sets the enclosure-temperature boundary.
Specify CBS350-24XS condition, quantities, destination-market ordering suffix, and connectivity accessories on the PO; ORM Systems offers new sealed units with up to a 3-year extended warranty and certified refurbished units with up to 1 year. Certified refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, optics bay recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. Every condition includes 30-day returns, with terms applying; Cisco's separate limited lifetime warranty cannot extend eligible coverage beyond 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 regions.

When several small-business locations need a common management approach, the embedded Cisco Business Dashboard probe removes the requirement for a separate on-site probe appliance or virtual machine. The Cisco Business mobile app also provides local management. Specify the intended administration workflow and site-specific configuration requirements before issuing the purchase order.
When an existing network needs additional routed segments, the switch supports 128 IP interfaces and can place Layer 3 interfaces on physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. Map the required interfaces to the network design, then check the interface allocation before specifying the order quantity.
When replacement switches must be prepared before shipment to another location, dual images and the front-panel USB Type-A slot support image and file handling during staging. Full and menu-based CLI options provide configuration access. Specify the required image, configuration handoff, and staging acceptance checks before releasing the purchase order.
PoE power for attached endpoints
CBS350-24XS supplies no PoE through its copper connections. Phones, cameras, or access points requiring switch-delivered power need a separate powered switch or an independent power source.
More than four copper connections
CBS350-24XS has four copper connections shared with SFP+ interfaces. C1300-24XTS provides twelve 10GE copper ports plus twelve dedicated SFP+ ports, changing the copper-to-fiber balance.
Active security maintenance for new deployments
CBS350-24XS security maintenance ended May 30, 2025. C1300-24XS is the current replacement for a new-hardware purchase retaining the 24-port SFP+ configuration with four shared copper connections.

CBS350-24XS identifies a Cisco Business 350 switch with 24 network ports in a 10 Gigabit SFP+ configuration. CBS350 identifies the series, 24 identifies the network-port count, and XS identifies the SFP+ configuration. Four connections also provide shared copper interfaces; CBS350-24XS-NA is the North American ordering variant.
CBS350-24XS provides 24 independent network connections: 20 dedicated 10G SFP+ interfaces and four 10G copper/SFP+ combo connections. A combo connection operates through only one medium at a time. The separate Gigabit Ethernet out-of-band management interface is for administration rather than an additional endpoint-facing network connection.
Cisco Business 350 switches support a web UI over HTTP/HTTPS, CLI access through SSH or the RJ-45 console, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP versions 1, 2c, and 3. Cisco Network Plug and Play supports provisioning, while the embedded Dashboard probe avoids a separate on-site probe installation.
No, CBS350-24XS does not provide PoE on its copper connections. The switch uses an internal AC power supply, and its shared copper interfaces carry network traffic without an endpoint power budget. Phones, cameras, and access points needing PoE require another power-delivery device or their own power source.
CBS350-24XS hardware stacking supports four members managed as a single system. Stack interconnects use 10G fiber interfaces, with ring and chain arrangements available. Reserve the required network interfaces for those links before allocating endpoint connections, and include the interconnect media and intended stack layout in the order specification.
CBS350-24XS supports SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber. Supported copper coax options include SFP-H10GB-CU1M, SFP-H10GB-CU3M, and SFP-H10GB-CU5M for 1 m, 3 m, and 5 m connections respectively. Match the selected accessory to the link medium and distance, and include its PID on the purchase order.
CBS350-24XS supports IPv4 static routing, RIP v2, and PBR, with 990 static routes and 128 IP interfaces. IPv6 routing is also supported. Interfaces can be assigned to physical ports, link aggregation groups, VLAN interfaces, or loopbacks. These capabilities place the switch in the Layer 2+ category rather than basic Layer 2 switching.
Yes, CBS350-24XS is a full-width rack-mount 1U switch measuring 440 mm wide, 350 mm deep, and 44 mm high, with a 4.4 kg weight. Its package includes a mounting kit. Allow for cable access and the four-fan cooling arrangement when specifying rack space and the installation location.
CBS350-24XS has a published worst-case consumption of 38.5W at 110V and 39W at 220V. Its internal universal supply accepts 100-240V AC at 50-60 Hz. Use the 39W maximum for switch power planning; there is no additional PoE endpoint budget to include for this model.
CBS350-24XS is discontinued, with an end-of-sale date of May 30, 2024. Software maintenance and vulnerability/security support ended May 30, 2025, while the last date of support is May 31, 2029. C1300-24XS is the current replacement, so an existing-estate purchase should account for the ended software-maintenance milestones.
CBS350-24XS replaces discontinued SX350X-24F-K9-EU, SX350X-24F-K9-IN, SX350X-24F-K9-NA, SX350X-24F-K9-UK, SX550X-24F-K9-AR, SX550X-24F-K9-AU, SX550X-24F-K9-BR, SX550X-24F-K9-JP, SX550X-24F-K9-EU, SX550X-24F-K9-IN, SX550X-24F-K9-NA, and SX550X-24F-K9-UK. Those predecessors reached end-of-sale on July 30, 2022. Match the regional ordering variant to the destination market and validate existing stack compatibility separately before changing hardware.
CBS350-24XS provides 20 dedicated SFP+ interfaces and four copper/SFP+ combo connections, whereas CBS350-24XTS provides twelve copper ports and twelve dedicated SFP+ ports. Both models are discontinued. CBS350-24XS serves fiber-heavy replacement orders; CBS350-24XTS fits existing mixed-media estates needing more copper connections without sharing their dedicated fiber interfaces.
CBS350-24XS provides 24 logical 10G network connections, whereas CBS350-12XS provides twelve. The larger model has four copper/SFP+ combo connections; the smaller model has two. Both are discontinued. Existing installations requiring more fiber connections fit CBS350-24XS, while lower-density replacement requirements fit CBS350-12XS after reserving the necessary uplink and stack interfaces.
C1300-24XS is the current successor to the discontinued CBS350-24XS, whose end-of-sale date was May 30, 2024. The replacement retains a 24-port SFP+ configuration with four shared 10GE copper connections. CBS350-24XS suits existing-equipment replacement purchases; C1300-24XS is the successor reference for buyers specifying a current model.
ORM Systems offers CBS350-24XS new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for refurbished units. Every condition has 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is separate, with eligible coverage bounded by the last date of support, May 31, 2029.
