CBS350-16XTS combines eight 10 Gigabit copper connections with eight dedicated 10 Gigabit SFP+ interfaces in a managed Layer 2+ switch for small-business networks. Its fixed optical interfaces can carry uplink traffic without an expansion card, and the copper connections provide data rather than PoE. The 1U rack-mount chassis belongs to the Cisco Business 350 Series and connects computers, servers, printers, and other independently powered equipment. The discontinued CBS350-16P-2G differs by supplying PoE+ from a shared 120W budget. A separate Gigabit management connection keeps administrative access distinct from the main data interfaces. Within the Cisco Business portfolio, this mixed copper-and-fiber configuration accommodates both cabling types without requiring either bank of data connections to share combo ports.
CBS350-16XTS price for new stock is $1,734.60, a 50% saving from the Cisco list price of $3,469.20. CBS350-16XTS refurb price is $1,097.25. CBS350-16XTS is in stock and available for free next-day delivery. (terms applied)

320 Gbps switching capacity provides nonblocking forwarding across the data interfaces. 238.08 Mpps forwarding at a 64-byte packet size describes the packet-processing ceiling for small-frame traffic. Static routing, RIP v2, and PBR handle local inter-subnet forwarding and next-hop selection; static routing supports 990 routes and 128 IP interfaces. CBS350-16XTS uses 512 MB of DRAM and 256 MB of flash for its operating environment and image storage. A dynamically shared 3 MB packet buffer accommodates traffic across the ports rather than dedicating a fixed allocation to each connection. STP/RSTP/MSTP provide loop control, while LACP combines eligible links. Browser configuration and command-line access support local administration; SNMP integrates monitoring with existing management tools. The MAC address table holds 16000 entries, and VLAN support reaches 4094 simultaneous VLANs for traffic separation. Firmware handling supports dual images, allowing an upgrade plan to retain a second software image.

CBS350-16XTS sits at the top of a compact server rack and terminates short 10GBASE-T runs from servers, storage, or security appliances on eight copper ports. Engineers use the eight dedicated 10G SFP+ ports for DAC or fiber links toward aggregation, preserving separate media paths instead of consuming combo interfaces. VLANs, LACP groups, jumbo frames up to 9K bytes, and the 1G management port organize host traffic and administration. The rack gains predictable 10G east-west switching and clear northbound handoff without expanding into a larger chassis platform.
CBS350-16XTS operates as a 10G member in a Cisco Business 350 distribution block where several compatible switches present one managed stack. Network teams place inter-closet or rack uplinks on the dedicated SFP+ ports and reserve the 10G copper ports for nearby firewall, router, or server handoffs. The stack applies shared VLAN, QoS, LAG, and port mirroring policies across members through a single management address. The distribution layer gains more 10G attachment points while keeping operations inside one Business 350 control plane.
The switch sits at the boundary between copper-connected equipment and fiber distribution, using eight 10GBASE-T ports for local devices and eight dedicated SFP+ ports for longer-reach uplinks. Engineers map endpoint VLANs to tagged trunks, use static routing or routed VLAN interfaces where internal segmentation terminates, and monitor neighbors through LLDP-MED, CDP, and SNMP. CBS350-16XTS separates production forwarding from administration through its 1G management port. The network gains a compact media-conversion aggregation point with governed Layer 2 and Layer 3 handoff.
When replacing a discontinued SX550X-16FT-K9-NA, the corresponding regional replacement is CBS350-16XTS-NA. Treat the change as a hardware refresh rather than assuming an existing configuration transfers unchanged. Before the PO, match the regional ordering identity and review the configuration, connection assignments, and management access required by the existing installation.
When several offices need centralized provisioning, Cisco Network Plug and Play supports deployment and configuration updates, while the embedded Cisco Business Dashboard probe removes the need for a separate probe appliance or virtual machine. Establish the provisioning workflow and management ownership before specifying the hardware quantities for each site.
When staging configurations or investigating traffic behavior, port mirroring supports eight source ports feeding one destination port. VLAN mirroring also supports eight source VLANs feeding one destination. Define the capture scope first, then reserve the analyzer connection and specify the required interface media before completing the lab purchase order.
Endpoint power from Ethernet ports
CBS350-16XTS provides data-only Ethernet connections and cannot supply endpoint power. Equipment that depends on PoE requires a separate power source rather than a switch-only connection.
Silent operation without cooling fans
CBS350-16XTS uses three fans and produces 39.1 dB at 25°C. An installation requiring fanless hardware cannot meet that requirement with this chassis.
Ongoing Cisco security maintenance
Security maintenance ended October 29, 2025 for CBS350-16XTS-NA. The current migration model, C1300-16XTS, retains eight 10G copper connections and eight 10G SFP+ connections.

CBS350-16XTS identifies a Cisco Business 350 managed switch with 16 data ports: eight 10 Gigabit copper ports and eight dedicated 10 Gigabit SFP+ ports. CBS350 names the series, and 16 reflects the data-port count. The complete 16XTS variant also includes a separate Gigabit management connection and a rack-mountable chassis.
CBS350-16XTS supports a web UI over HTTP/HTTPS, CLI through the RJ-45 console or SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app, SNMP, and Cisco Network Plug and Play. The embedded Dashboard probe avoids a separate probe appliance or virtual machine, while the CLI supports scripted administration.
Yes, CBS350-16XTS is discontinued; the North American CBS350-16XTS-NA reached end of sale on October 29, 2024. Software maintenance and security support ended October 29, 2025, while the last date of support is October 31, 2029. C1300-16XTS is the current migration model for the same copper-and-SFP+ connection arrangement.
ORM Systems offers CBS350-16XTS new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Both conditions have 30-day returns; terms apply. Cisco's limited lifetime warranty is separate, with Cisco service ending October 31, 2029 for CBS350-16XTS-NA. Refurbished units are inspected and bench-tested.
CBS350-16XTS replaced SX550X-16FT-K9-AR, SX550X-16FT-K9-AU, SX550X-16FT-K9-BR, SX550X-16FT-K9-CN, SX550X-16FT-K9-EU, SX550X-16FT-K9-IN, SX550X-16FT-K9-JP, SX550X-16FT-K9-NA, and SX550X-16FT-K9-UK. These discontinued Cisco 550X models reached end of sale on July 30, 2022. Regional replacements retain corresponding suffixes; for example, CBS350-16XTS-NA replaced SX550X-16FT-K9-NA. Confirm regional identity before matching an existing installation to a spare.
CBS350-16XTS supports static routing, RIP v2, and PBR, with 990 static routes and 128 IP interfaces. Routing interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. IPv4 and IPv6 forwarding are supported, making this a Layer 2+ configuration under a static-routing-and-RIP classification.
CBS350-16XTS hardware stacking supports four members, with ring or chain arrangements and 10G fiber interconnects. Stack control uses active and standby roles. Supported 10G direct-attach connection options include SFP-H10GB-CU1M at 1 m, SFP-H10GB-CU3M at 3 m, and SFP-H10GB-CU5M at 5 m; reserve interconnect interfaces before assigning other connections.
CBS350-16XTS uses an internal universal AC supply accepting 100-240V AC at 50-60 Hz, without a redundant PSU option. Maximum consumption is 57W at 110V or 57.7W at 220V. The chassis takes mains power directly rather than requiring an external adapter, and its Ethernet connections do not provide PoE output.
CBS350-16XTS supports SFP-10G-SR and SFP-10G-SR-S for multimode fiber, plus SFP-10G-LR and SFP-10G-LR-S for single-mode fiber. The eight dedicated SFP+ interfaces remain separate from the eight copper data connections. Specify the required transceiver PID and match the fiber type and far-end interface when preparing the order.
CBS350-16XTS occupies 1U in a standard equipment rack, with a chassis measuring 440 mm wide, 257 mm deep, and 44 mm high. The unit weighs 3.79 kg. Mounting hardware is included with the device, but mounting accessories are not available separately as spare parts.
CBS350-16P-2G provides 120W shared across 16 PoE+ ports, whereas CBS350-16XTS supplies no PoE. Both models are discontinued. Existing-installation spares must preserve endpoint power requirements: the PoE model serves powered endpoints, while the data-only model serves connections whose equipment has its own power source.
CBS350-24XTS has 12 copper and 12 dedicated SFP+ data connections, compared with eight of each on CBS350-16XTS. Both discontinued models use 10 Gigabit data interfaces. The larger configuration fits existing installations needing more mixed-media connections, while the smaller configuration matches installations built around the lower connection count.
C1300-16XTS is the current migration model, while CBS350-16XTS is discontinued and its North American version ended software and security maintenance on October 29, 2025. Both provide eight 10G copper and eight 10G SFP+ connections. The former addresses migration purchases; the latter addresses existing-installation replacement requirements within its remaining support window.
