SG350-10-K9-UK combines fanless cooling with managed Layer 2+ switching in a desktop chassis. Eight 10/100/1000 RJ-45 access ports connect local endpoints, while two fixed 1G copper/SFP combo uplinks provide upstream connectivity. Each combo uplink activates either its copper connector or its SFP cage, not both simultaneously. The Cisco 350 Series serves small-business networks connecting workstations, servers and other Ethernet devices. Unlike the discontinued SG350-10P-K9-UK, which supplies PoE+ with a 62W budget, this non-PoE variant carries data without powering attached endpoints. An external AC adapter powers the chassis, keeping mains power conversion outside the switch enclosure.

20 Gbps switching capacity supports wire-speed, nonblocking operation across the fixed interfaces. 14.88 Mpps forwarding performance is rated with 64-byte packets, so packet size matters when comparing traffic requirements. Static IPv4 routing supports 990 routes and 128 IP interfaces; PBR directs traffic using IPv4 or IPv6 ACLs. STP, RSTP and MSTP provide loop-control options, while LACP supports link aggregation. SG350-10-K9-UK carries 512 MB of DRAM and 256 MB of flash, separating working memory from image storage. A shared 1.5 MB packet buffer serves all ports, and the MAC table supports 16000 addresses. Management of this Cisco Small Business switch includes browser configuration, a scriptable CLI and SNMP, with an RJ-45 console connection for local access. The USB Type-A interface supports configuration and image transfer. 9.8W maximum system consumption supplies the switch-load figure for AC power planning.
Choose new sealed or certified refurbished SG350-10-K9-UK and specify the required condition, supplied adapter and accessories on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, every port's rated-speed link, clean boot and optics bay recognition; the supplied adapter delivers rated output, firmware is verified and configuration is wiped to factory default. ORM warranties provide up to 3-year extended coverage for new units and up to 1 year for certified refurbished units, with 30-day returns on both conditions, terms apply; Cisco's Limited Lifetime warranty is separate and Cisco service ends October 31, 2026. Volume orders use PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock and RMA across UK, EU, US and MEA.

When an existing inventory references SRW2008-K9-G5, SG350-10-K9-UK provides the replacement identity for asset records and spare selection. Carry the original port assignments and saved configuration into staging rather than assuming configuration equivalence. Specify the exact regional part number, required condition and accessory contents before issuing the purchase order.
When multiple locations need repeatable configurations, text-editable configuration files and autoconfiguration through SCP support a common staging workflow. The 350 Series CLI separates access into privilege levels 1, 7 and 15. Specify the approved configuration file, management credentials and staging sequence before issuing the purchase order.
When a test bench needs packet inspection before production changes, port mirroring supports eight source ports to one destination port within a single session. A network analyzer receives the mirrored traffic. Specify the analyzer connection, source-port selection and saved configuration required for the staging exercise before the purchase order.
Ethernet power for attached endpoints
SG350-10-K9-UK supplies no PoE to attached devices. C1300-8P-E-2G is the current eight-port PoE alternative with two 1G combo uplinks and an external power supply.
10G connections to distribution
SG350-10-K9-UK has fixed 1G combo uplinks. Neither an SFP+ transceiver nor a removable uplink card can turn those interfaces into a 10G distribution connection.
Cisco support beyond October 2026
SG350-10-K9-UK reaches its last date of Cisco support on October 31, 2026. C1300-8T-E-2G is the current successor; the intermediate CBS350-8T-E-2G-UK is also discontinued.

SG350-10-K9-UK combines SG350 for the 350 Series Gigabit managed family, 10 for eight copper ports plus two copper/SFP combo ports, and UK for the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia. K9 remains part of the complete product identifier.
SG350-10-K9-UK supports HTTP/HTTPS web management, a CLI through the RJ-45 console or SSH/Telnet, and SNMP versions 1, 2c and 3. Network-level tools include Smart Network Application, FindIT Network Manager with its embedded probe, FindIT Network Discovery Utility and Active Advisor. The browser interface provides simple and advanced configuration modes.
Yes, SG350-10-K9-UK is discontinued: end of sale was October 30, 2021, and Cisco support ends October 31, 2026. Software maintenance ended October 30, 2022. The immediate replacement, CBS350-8T-E-2G-UK, is also discontinued; the current migration chain ends at C1300-8T-E-2G for new replacement purchases.
SG350-10-K9-UK replaces SRW2008-K9-G5, the SG300-10 ten-port Gigabit managed switch. The older identifier remains useful when matching inventory records, installed spares and replacement requests. SG350-10-K9-UK is itself discontinued, so an existing-estate spare order and a new network standardization order have different lifecycle considerations.
ORM Systems offers SG350-10-K9-UK new sealed or certified refurbished, with up to 3-year extended warranty for new units and up to 1 year for certified refurbished units. Returns cover 30 days in either condition; terms apply. Cisco's Limited Lifetime hardware warranty is separate, with Cisco service ending October 31, 2026.
SG350-10-K9-UK provides eight dedicated 10/100/1000 copper access ports and two Gigabit copper/SFP combo uplinks, for ten usable network ports. Each combo pair shares one logical interface, so copper and fiber cannot operate simultaneously within that pair. The separate RJ-45 console connection handles management rather than Ethernet traffic.
The Cisco SG350-10 supports MGBSX1 for 1G multimode fiber links to 500 m and MGBLX1 for 1G single-mode fiber links to 10 km. Match the selected PID to the fiber type and remote connection. MGBSX1 and MGBLX1 occupy the fixed SFP cages rather than adding separate switch interfaces.
Yes, SG350-10-K9-UK supports inter-VLAN communication through static IPv4 routing, with a maximum of 990 static routes and 128 IP interfaces. PBR can choose a next hop using IPv4 or IPv6 ACLs. Specify the interface configuration and static routes required for communication between the intended network segments.
The Cisco SG350-10 uses an external AC adapter accepting 100-240V AC at 50-60 Hz. Maximum system consumption is 9.8W. Include the supplied adapter in the requested order contents, and match the regional power arrangement to the installation location. Power conversion occurs outside the desktop chassis rather than through an internal supply.
The Cisco SG350-10 provides 20 Gbps switching capacity and 14.88 Mpps forwarding at 64-byte packet size, with wire-speed, nonblocking operation. Capacity and packet rate describe different limits, so compare both with the expected traffic profile. The forwarding figure is a packet-size-specific rating rather than a general application-throughput guarantee.
SG350-10P-K9-UK adds eight PoE+ access ports with a shared 62W budget; SG350-10-K9-UK does not supply endpoint power. Both are discontinued, and C1300-8P-E-2G is the current powered successor. The PoE model suits existing estates with powered endpoints, while the non-PoE model suits endpoints using separate supplies.
SG350-20-K9-UK uses an internal AC supply and sixteen dedicated Gigabit access ports, whereas SG350-10-K9-UK uses an external adapter and eight access ports. Both are discontinued; the larger model's current successor is C1300-16T-2G. Existing-estate buyers choose between internal mains power with higher port density and the smaller externally powered desktop unit.
C1300-8T-E-2G is the current successor, while SG350-10-K9-UK is discontinued and reaches its Cisco support deadline on October 31, 2026. The intermediate CBS350-8T-E-2G-UK is also discontinued. The older model suits exact-match replacement in an existing installation; C1300-8T-E-2G suits buyers selecting the current eight-port Gigabit replacement.
SG350-10-K9-UK-RF is Cisco-remanufactured hardware, whereas certified refurbished SG350-10-K9-UK is refurbished by ORM Systems. ORM's process includes inspection and bench testing, with firmware verification and configuration wiped to factory default for this managed unit. Specify the refurbishment type explicitly; the two condition descriptions are not interchangeable.
