CBS350-24XTS combines twelve 10 Gigabit RJ-45 ports with twelve dedicated 10 Gigabit SFP+ interfaces in a managed Layer 2+ switch. The fixed fiber interfaces operate alongside the copper connections without combo-port sharing, and the chassis occupies a full-width 1U rack position. The Business 350 series serves small-business networks connecting servers and other network devices; this non-PoE configuration requires independently powered endpoints. CBS350-24P-4X, also discontinued, instead supplies PoE to Gigabit endpoints. A mixed copper-and-fiber 10 Gigabit switch accommodates different physical media without a removable uplink-card purchase, making the required copper connections and fiber links the starting point for the hardware configuration.
CBS350-24XTS price for new stock is $3,493.35, a 50% saving from the Cisco list price of $6,986.70. CBS350-24XTS refurb price is $2,667.00. CBS350-24XTS is in stock and available for next-day dispatch. (terms applied)

480 Gbps switching capacity supports nonblocking traffic across the fixed interfaces, while 240 Mpps forwarding handles minimum-size packets. Static routing and RIP v2 provide routed connectivity between IP interfaces; PBR selects a next hop using ACL matches. STP/RSTP/MSTP control switching loops, with multiple spanning-tree instances available for separate VLAN groups. Management can use the browser interface or a console session, while the USB connection supports configuration and firmware-image transfers. CBS350-24XTS carries 512 MB of DRAM, 256 MB of flash and a 3 MB packet buffer shared across ports rather than allocated permanently to individual interfaces. The independent Gigabit out-of-band connection provides a separate administrative interface. That management port does not bridge traffic into the in-band Layer 2 network, so its connection must remain separate from the switched data path.
ORM Systems offers CBS350-24XTS in new sealed and certified refurbished condition, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units, plus 30-day returns on every condition; terms apply. 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, with firmware verified and configuration wiped to factory default. Specify condition, region and required connectivity parts on the purchase order. For enterprise and volume purchasing, PO accepted, Net-30 for government and RMA with advance replacement are supported across UK, EU, US and MEA.

An existing SX550X-24FT-K9-NA installation can trigger a CBS350-24XTS replacement purchase when a unit fails or a refresh is scheduled. Inventory the attached copper and fiber connections, preserve the configuration for review, and confirm the required condition and regional order variant before issuing the PO.
A switch being configured on an isolated staging bench uses 192.168.1.254/24 when no DHCP address is obtained. The configuration computer needs an unused address on the same subnet. Arrange bench connectivity and an address-assignment plan before ordering hardware for the staging batch.
An existing hardware stack creates an expansion order that must preserve its connection layout. Business 350 stack settings distinguish Native Stacking for the same device type from Hybrid Stacking for mixed types. Confirm the required mode and whether the existing layout is a ring or chain before specifying the added unit.
Continuing Cisco security maintenance
CBS350-24XTS vulnerability and security maintenance ended May 30, 2025. C1300-24XTS is the current replacement and retains twelve 10 Gigabit copper ports plus twelve SFP+ ports.
RIP v2 on DHCP-addressed interfaces
CBS350-24XTS cannot run RIP v2 on DHCP-assigned or default-address interfaces. RIP v2 requires manually configured IP addresses, so automatic interface addressing cannot satisfy that combination.

CBS350-24XTS identifies a Business 350 switch combining twelve 10 Gigabit copper ports with twelve dedicated 10 Gigabit SFP+ ports. CBS350 names the series; 24XTS selects that mixed configuration. The final configuration segment does not identify twenty-four copper ports or a separate license tier.
Cisco Business 350 switches support browser management, CLI access through the console or SSH, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. These paths serve different administrative workflows. Establish the intended management connection and access controls before transferring a staged configuration into the production network.
Yes, CBS350-24XTS ended sale on May 30, 2024, and software maintenance and vulnerability/security support ended May 30, 2025. The last date of eligible Cisco support is May 31, 2029. C1300-24XTS is the current migration target; remaining hardware availability does not extend those milestones.
ORM Systems offers CBS350-24XTS new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are 30 days on every condition; terms apply. Cisco's separate limited lifetime hardware warranty is subject to eligibility and ends May 31, 2029.
CBS350-24XTS replaces SX550X-24FT-K9-AU, SX550X-24FT-K9-EU, SX550X-24FT-K9-JP, SX550X-24FT-K9-NA and SX550X-24FT-K9-UK, which ended sale July 30, 2022. Both generations are now discontinued. For a legacy replacement, match the destination region and review the existing connections and configuration before specifying the order.
CBS350-24P-4X supplies PoE to Gigabit endpoints, while CBS350-24XTS provides mixed copper and SFP+ 10 Gigabit connectivity without endpoint power. Both models are discontinued. CBS350-24XTS suits a legacy purchase for independently powered 10 Gigabit equipment; CBS350-24P-4X addresses a legacy requirement for powered Gigabit endpoints.
CBS350-24XTS provides twelve copper and twelve SFP+ 10 Gigabit ports, whereas CBS350-16XTS provides eight of each. Both are discontinued. CBS350-24XTS accommodates the larger mixed-media connection count; CBS350-16XTS fits a smaller legacy installation whose copper and fiber requirements remain within its eight-port allocations.
CBS350-24XTS is discontinued, while C1300-24XTS is its current replacement for new purchases. The older model's security maintenance has already ended, which matters when specifying another unit. CBS350-24XTS addresses an exact legacy-hardware requirement; C1300-24XTS suits a migration purchase rather than extending the older product's lifecycle.
Four CBS350-24XTS switches can form a hardware stack managed as one logical system. Network ports must be configured for stack connections rather than remaining ordinary data interfaces. Choose the connection topology, reserve the required ports and save the configuration before rebooting to apply the stack settings.
Yes, CBS350-24XTS supports routed IP interfaces using static routing and RIP v2, with PBR available for policy-selected next hops. RIP v2 must be enabled globally and on the relevant interfaces. Those interfaces need manually configured addresses; DHCP-assigned and default-address interfaces cannot participate in RIP v2.
SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M are supported copper interconnect options for Cisco Business 350 SFP+ ports. These cable assemblies connect through the SFP+ interfaces rather than RJ-45 sockets. Specify the required cable PID and confirm the connection at both ends before adding the interconnect to the order.
CBS350-24XTS uses 192.168.1.254/24 when a DHCP address is not obtained during initial setup. The configuration computer must use an unused address in that subnet. If DHCP assigns another address, use that assigned address instead and confirm reachability before opening the browser-based configuration utility.
