SX350X-08-K9-EU provides 10GBASE-T connectivity for small-business servers and network storage in an eight-port managed switch. Six dedicated copper network ports sit alongside two fixed copper/SFP+ combo uplinks; each combo position selects one medium rather than operating both interfaces simultaneously. The Cisco 350X Series combines Layer 2+ switching and static routing in a rack-mount 1U chassis, without PoE output or a removable uplink module bay. A dedicated 1G out-of-band management port separates administrative access from data traffic. The discontinued SX350X-12-K9-EU provides twelve data ports for a higher-density version of the copper-oriented configuration. The SX350X-08 supports 1G as well as 10G data connections, allowing compatible existing endpoints to remain connected during a speed transition.

160 Gbps switching capacity provides nonblocking forwarding across the available data interfaces. 119.05 Mpps forwarding performance is rated with 64-byte packets, giving a packet-rate reference for evaluating traffic with small frame sizes. 990 static IPv4 routes and 128 IP interfaces bound routed LAN configurations; IPv6 supports 245 static routes and 106 interfaces. Dynamic route exchange is not part of this switch's routing capability. SX350X-08-K9-EU carries 512 MB of DRAM and 256 MB of flash for its embedded software and configuration storage. A 32000-entry MAC table accommodates learned device addresses, while the 3 MB packet buffer is dynamically shared across ports. STP/RSTP/MSTP control Layer 2 loops, and LACP supports aggregated links. Eight hardware queues provide traffic scheduling, with strict priority and weighted round-robin operation. 50.3W worst-case power consumption supplies the maximum draw to include in electrical sizing. Two fans provide active cooling rather than silent, fanless operation.
ORM Systems supplies SX350X-08-K9-EU 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; every condition carries 30-day returns, with terms applying. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. Specify this switch's quantity, condition, and delivery region on the purchase order. ORM Systems accepts POs for enterprise and volume orders and provides Net-30 terms for government buyers.

An existing mixed-speed 350X stack requiring another 10G member needs an interconnect plan before expansion. SG350X, SG350XG, and SX350X members can share ring or chain arrangements, using fiber or copper interconnects and link aggregation for stack links. Allocate the intended stack interfaces and order compatible interconnect cables with the additional unit.
Several sites requiring the same access controls can be staged with reusable text-editable configurations and secure SCP transfers. SX350X models support 2000 ACL entries, so validate each site's rule set against that ceiling before copying configurations. Specify the staging configuration and quantity for each location on the purchase order.
An installed estate requiring like-for-like replacement units can hold SX350X-08-K9-EU spares under its existing regional ordering identity. ORM Systems provides regional stock and RMA handling across the UK, EU, US, and MEA. Define spare quantities, required condition, and the applicable regional RMA destination before placing the purchase order.
Endpoint power through Ethernet
SX350X-08-K9-EU does not provide PoE output. Network endpoints needing power from the Ethernet link require a separate power source or a powered switching path rather than this model.
Ten independent data connections
SX350X-08-K9-EU has eight logical data ports; its combo interfaces share their associated copper positions. Ten independent data connections exceed the chassis even when both SFP+ cages are populated.
Cisco support beyond July 2027
Cisco service for SX350X-08-K9-EU ends July 31, 2027. CBS350-8XT-EU, the discontinued successor, has no current migration product, so this replacement chain offers no current model for ongoing standardization.

SX350X-08-K9-EU is the EU regional ordering variant of the eight-port 10GBASE-T managed switch in the Cisco 350X Series. SX350X identifies the 10 Gigabit Ethernet model group, 08 identifies eight data ports, and EU selects the regional ordering suffix. Two data positions provide shared copper/SFP+ connectivity rather than additional independent ports.
SX350X-08-K9-EU is managed through a browser-based web interface, a full or menu CLI over console, SSH or Telnet, and SNMP. Additional paths include Smart Network Application, FindIT Network Manager, the embedded FindIT Network Probe, and Active Advisor. Cisco Network Plug and Play supports coordinated provisioning across an installation.
SX350X-08-K9-EU ended sale July 30, 2022, and Cisco support ends July 31, 2027. Software maintenance ended July 30, 2023. CBS350-8XT-EU, the named successor, is also discontinued: its end-of-sale date was October 29, 2024, and no current migration product is available for that model.
ORM Systems offers SX350X-08-K9-EU new sealed or certified refurbished. New units carry up to a 3-year extended warranty; refurbished units carry up to 1 year. Returns are available for 30 days on every condition; terms apply. Cisco's limited lifetime hardware warranty is separate, with Cisco service ending July 31, 2027.
SX350X-08-K9-EU has two fixed 10G copper/SFP+ combo uplinks, each sharing one logical position between its copper connector and optical cage. Only one medium operates per combo position. Fiber connections can use SFP-10G-SR= or SFP-10G-LR=; specify the appropriate transceiver and fiber type rather than treating the optical cages as extra ports.
The Cisco 350X Series provides static IPv4 and IPv6 routing, with 990 IPv4 routes and 128 IP interfaces. The IPv6 limit is 245 static routes and 106 interfaces. Layer 2+ functionality covers inter-VLAN communication using configured routes; routed LAN requirements must fit those limits rather than assuming dynamic route exchange.
The Cisco 350X Series forms a true horizontal stack of four members and permits mixed SG350X, SG350XG, and SX350X units. Copper interconnect options include SFP-H10GB-CU1M=, SFP-H10GB-CU3M=, and SFP-H10GB-CU5M=. Specify ring or chain topology and allocate the stack interfaces before ordering; interfaces committed to stacking are unavailable for endpoint connections.
SG350X-8PMD-K9-EU supplies 240W of PoE power across eight powered ports, whereas SX350X-08-K9-EU provides no PoE output. Both models are discontinued. SG350X-8PMD-K9-EU suits retaining a powered-endpoint installation; SX350X-08-K9-EU suits an existing non-powered 10G deployment, where endpoint power supplies remain separate from Ethernet connectivity and no switch-delivered power is required.
SX350X-12-K9-EU provides twelve logical data ports, compared with eight on SX350X-08-K9-EU. Both models include two shared copper/SFP+ positions and are discontinued. SX350X-08-K9-EU suits eight-port like-for-like replacement orders, whereas SX350X-12-K9-EU fits established installations requiring the larger port count; either order must preserve the existing regional variant.
SX350X-08-K9-EU ended sale July 30, 2022, while CBS350-8XT-EU ended sale October 29, 2024. The replacement retains an eight-port 10G configuration with two shared SFP+ positions, but is also discontinued and has no current migration product. SX350X-08-K9-EU suits 350X spares; CBS350-8XT-EU suits like-for-like CBS350 estate maintenance rather than a current-model refresh.
