SG350-10SFP-K9-EU is a fanless Layer 2+ desktop switch for small-business fiber aggregation, with eight fixed Gigabit SFP slots and two fixed Gigabit copper/SFP combo connections. Each combo connection uses copper or fiber, with only one medium active at a time. The Cisco 350 Series combines managed switching with configurable traffic separation for business networks connecting switches and network resources over fiber. Ports carry data without supplying PoE, so connected equipment needs another power source. The discontinued SG350-10P supplies PoE+ through copper access ports instead of the fiber-focused arrangement here. This Gigabit managed SFP switch addresses an existing optical connection requirement rather than a requirement for powered copper endpoints or higher-speed uplinks.

20 Gbps switching capacity provides wire-speed, nonblocking operation, while 14.88 Mpps forwarding defines performance with 64-byte packets. Static IPv4 routing supports 990 routes and 128 IP interfaces for communication between configured networks; PBR selects next hops through IPv4 or IPv6 ACLs. Dynamic routing is not part of the feature set. SG350-10SFP-K9-EU carries 512 MB of memory and 256 MB of flash for its operating software and configuration. A dynamically shared 1.5 MB packet buffer serves traffic across all ports. Support for 4094 simultaneous VLANs separates traffic, and the MAC table accommodates 16000 addresses. STP, RSTP, and MSTP control bridge topology; LACP groups connections into logical links. Administrators can configure the switch through HTTPS or the Textview CLI and monitor it through SNMP. For electrical planning, 11.9W worst-case consumption at 220V defines the switch's maximum published draw rather than an endpoint power allowance.
Specify SG350-10SFP-K9-EU in new sealed or certified refurbished condition, with quantity and required optics on the PO. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, and optics bay recognition; firmware is verified and configurations are wiped to factory default. ORM provides up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition, terms apply; Cisco's separate Limited Lifetime warranty ends July 31, 2027. Enterprise and volume orders support PO acceptance, Net-30 for government, and RMA with advance replacement, with regional stock and RMA coverage across the UK, EU, US, and MEA.

An installed fleet of discontinued SG300-10SFP-K9-EU switches creates a replacement-spare requirement rather than a new equipment standard. This model is the named replacement for that older switch. Before issuing the PO, reconcile the installed inventory, required condition, existing configuration requirements, and quantity of replacement units.
A staging team preparing replacement equipment can use dual firmware images and the front-panel USB connection for image and configuration handling. Keep the approved image and configuration files with the staging record, distinguish the two firmware images, and specify the required preparation work before the PO.
10G optical uplink connections
The fixed optical connections operate at Gigabit speed, not 10G. An installation requiring a 10G optical handoff needs different switching hardware rather than a different transceiver alone.
Power delivery to copper endpoints
The copper combo connections do not supply PoE. Phones, cameras, or access points that require power through their Ethernet connection need a separate power arrangement.

SG350-10SFP-K9-EU identifies a 350 Series managed Gigabit SFP switch with ten network connections. SG350 names the model family; 10SFP identifies eight dedicated SFP slots plus two copper/SFP combo ports. EU selects the regional ordering form. Retain K9 when matching the complete part number.
SG350-10SFP-K9-EU supports HTTP/HTTPS browser management, a Textview CLI through the RJ-45 console or SSH/Telnet, and SNMP. FindIT Network Manager and Probe provide network management, FindIT Network Discovery assists device discovery, and the embedded Smart Network Application provides topology monitoring and configuration across supported networks.
SG350-10SFP-K9-EU is discontinued, with end of sale on July 30, 2022 and last support on July 31, 2027. Software maintenance ended July 30, 2023. Remaining Cisco service depends on applicable entitlement and cannot extend beyond the final support date; reseller availability does not mean current Cisco production.
New sealed and certified refurbished SG350-10SFP-K9-EU units are offered with separate ORM and Cisco warranty terms. ORM provides up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Returns are 30 days on every condition, terms apply. Cisco's Limited Lifetime warranty ends July 31, 2027.
SG350-10SFP-K9-EU replaces the discontinued SG300-10SFP-K9-EU Gigabit managed SFP switch. The older model provides the starting point for a legacy replacement requirement, but the replacement is itself discontinued. Match the complete regional PID and review the intended configuration before treating existing equipment as interchangeable.
The SG350-10SFP supports MGBSX1 for multimode fiber to 500 m and MGBLX1 for single-mode fiber to 10 km. MGBLH1 supports single-mode connections to 40 km. Select the transceiver against the installed fiber and connection distance, and match the optical connection at the opposite end.
Yes, SG350-10SFP-K9-EU supports static IPv4 routing between configured networks, with 990 static routes and 128 IP interfaces. PBR provides next-hop selection using IPv4 or IPv6 ACLs. The routing feature set is static rather than dynamic, so confirm that the intended network does not require dynamic route exchange.
SG350-10SFP-K9-EU uses an external AC adapter with a 100-240V AC, 50-60 Hz input range. Worst-case switch consumption reaches 11.9W at 220V. Installation planning must accommodate the separate adapter and its lead, rather than treating this desktop switch as equipment with an internal AC supply.
SG350-10P supplies PoE+ to eight ports with a 62W budget, while SG350-10SFP-K9-EU supplies no PoE. Both models are discontinued. For legacy sparing, SG350-10P addresses powered copper endpoint connections; SG350-10SFP-K9-EU addresses data-only fiber connections where endpoint power is supplied separately.
SG350-20 uses an internal universal AC supply, while SG350-10SFP-K9-EU uses an external AC adapter. Both models are discontinued. SG350-20 matches legacy installations requiring an internal power connection; SG350-10SFP-K9-EU requires a separate adapter location and power-lead arrangement when specifying a replacement spare.
SG350-28SFP provides 24 SFP access slots plus two additional dedicated SFP ports, while SG350-10SFP-K9-EU has eight dedicated SFP slots. Both models are discontinued. The larger legacy model addresses fiber-port consolidation; the desktop model fits smaller connection counts. Match the required fiber inventory when selecting a replacement spare.
CBS350-8S-E-2G-EU replaced SG350-10SFP-K9-EU, but that replacement is also discontinued and has no current migration product. Its end-of-sale date was May 30, 2024, and its last support date is May 31, 2029. The replacement chain therefore does not lead to a current-production equivalent.
No, the SG350-10SFP is a fanless desktop switch measuring 279.4 mm wide, 44 mm high, and 170 mm deep. Its weight is 2.08 kg. The narrow chassis is not a full-width rack unit, so confirm the installation arrangement rather than assuming the chassis spans a standard equipment rack.
