SG350-10-K9-NA combines fanless operation with managed Gigabit access in a desktop chassis for small-business networks. This Layer 2+ model provides eight 10/100/1000 copper access ports and two fixed Gigabit copper/SFP combo uplinks, without endpoint PoE output. The Cisco 350 Series supports configurable wired switching and local network segmentation in smaller business installations. Each combo uplink activates either its copper connection or its fiber connection, not both simultaneously. The discontinued SG350-10P-K9-NA is the powered sibling, adding a shared 62W PoE+ budget. Specify the non-PoE configuration for independently powered equipment, and confirm whether the upstream connection requires copper cabling or a compatible fiber transceiver before selecting the accompanying parts.

20 Gbps switching capacity supports nonblocking traffic handling across the installed interfaces. 14.88 Mpps forwarding applies to 64-byte packets at wire speed. Static routing provides 990 IPv4 routes for configured next-hop forwarding, while PBR selects next hops using IPv4 or IPv6 access rules. SG350-10-K9-NA combines 512 MB of memory for running management software with 256 MB of flash for stored images. A dynamically shared 1.5 MB packet buffer handles traffic bursts across ports, and the MAC table accommodates 16000 learned addresses. STP/RSTP/MSTP provide loop control, while LACP supports link aggregation rather than hardware stacking. Browser configuration, a scriptable CLI, and SNMP provide administration paths, with SSH available for protected remote sessions. The SG350-10 draws power through an external adapter; worst-case consumption of 9W at 110V and 9.8W at 220V provides the electrical figures for mains-load planning.
Specify SG350-10-K9-NA in new sealed or certified refurbished condition, and confirm the required quantity and accompanying power adapter on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every network port, optics bay recognition, and rated adapter output; firmware is verified and configurations are wiped to factory default. ORM provides up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, with 30-day returns in every condition; terms apply. For enterprise and volume orders, POs are accepted, government buyers receive Net-30, and RMA includes advance replacement.

When a small-business rollout moves local traffic between VLANs, interface scale becomes an ordering constraint. The switch supports 128 IP interfaces, so inventory routed VLANs and other routing interfaces together rather than considering only physical port count. Finalize the interface plan and configuration ownership before the purchase order.
When replacement switches must be prepared before installation, the Textview CLI provides scriptable configuration with privilege levels 1, 7, and 15. Define operator and administrator roles in the staging workflow, retain the approved configuration outside the unit, and specify who will apply the settings after delivery before issuing the purchase order.
When SG350-10-K9-NA replacement inventory must cover several offices, ORM handles regional stock and RMA requirements across the UK, EU, US, and MEA. Keep the regional ordering identity aligned with the installed fleet, and allocate condition, site quantities, and delivery destinations explicitly before submitting a consolidated purchase order.
Power delivery to attached endpoints
SG350-10-K9-NA does not supply PoE to connected devices. C1300-8P-E-2G is a current eight-port Gigabit powered alternative with two 1G combo uplinks and an external adapter.
10G links to upstream switches
SG350-10-K9-NA stops at 1G uplinks. C1300-8MGP-2X provides two 10G SFP+ uplinks, but changes access connectivity to four 2.5G ports plus four Gigabit ports and adds PoE.

SG350-10-K9-NA identifies the 350 family's ten-port Gigabit managed model for the NA sales region. SG350 selects the Gigabit model family; 10 includes eight copper access ports and two copper/SFP combo ports. NA covers the United States, Canada, Mexico, Colombia, Chile, and other Latin American markets; retain K9 in the ordering identifier.
SG350-10-K9-NA supports browser management through HTTP/HTTPS, console access, CLI sessions over SSH or Telnet, and SNMP versions 1, 2c, and 3. Additional integrations include Smart Network Application, Cisco FindIT Network Manager with an embedded probe, and Cisco Active Advisor. Select the appropriate local interface or compatible management application for configuration and monitoring.
SG350-10-K9-NA has two Gigabit combo uplinks, each sharing one logical port between an RJ-45 connection and an SFP cage. Only one connection in each pair operates at a time. The switch therefore has ten system ports, including eight dedicated copper access ports; select copper or fiber independently for each uplink.
SG350-10-K9-NA provides static routing with 990 IPv4 routes and PBR for policy-controlled next-hop selection. Routing interfaces can be physical ports, LAGs, VLAN interfaces, or loopbacks. PBR can use IPv4 or IPv6 access rules. Specify static next hops and policy requirements for local forwarding rather than expecting dynamic routing-protocol adjacency.
SG350-10 is a fanless desktop switch measuring 280 mm wide, 44 mm high, and 170 mm deep. The chassis weighs 1.09 kg and operates from 0°C to 50°C. Allow space for the switch and its external adapter rather than assuming a full-width rack chassis; a mounting kit accompanies the switch.
SG350-10-K9-NA uses an external AC adapter accepting 100-240V AC at 50-60 Hz. Worst-case consumption is 9W at 110V and 9.8W at 220V. The switch does not use internal redundant power-supply modules; include adapter requirements and regional mains compatibility in the purchase order rather than ordering a chassis power supply.
SG350-10-K9-NA is discontinued: Cisco sales ended October 30, 2021, and service ends October 31, 2026. Software maintenance ended October 30, 2022. Its original replacement, CBS350-8T-E-2G-NA, is also discontinued; C1300-8T-E-2G is the current migration endpoint. Treat hardware availability and remaining Cisco service eligibility as separate ordering questions.
ORM Systems offers SG350-10-K9-NA new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are available for 30 days in either condition; terms apply. Cisco's limited lifetime hardware warranty is bounded by the October 31, 2026 support cutoff.
SG350-10-K9-NA replaces SRW2008-K9-NA, a ten-port Gigabit managed switch whose Cisco sales ended August 2, 2018. The predecessor's Cisco service ended August 31, 2023. SG350-10-K9-NA is itself discontinued, so use C1300-8T-E-2G for current migration planning rather than stopping at the historical replacement when specifying a new standard.
SG350-10P-K9-NA supplies PoE+ on eight access ports with a shared 62W budget, while SG350-10-K9-NA provides data connections only. Both models are discontinued. The powered model is a like-for-like reference for an existing powered fleet; the non-PoE model suits replacement positions where endpoint power comes from separate supplies.
SG350-20-K9-NA uses an internal AC supply, whereas SG350-10-K9-NA relies on an external adapter. Both models are discontinued. The larger model suits like-for-like installations standardized on internal mains power; the compact model suits existing deployments organized around a separate adapter, where replacement purchasing must preserve that power arrangement.
C1300-8T-E-2G is the current migration endpoint for SG350-10-K9-NA, whose Cisco sales ended October 30, 2021. The intermediate CBS350-8T-E-2G-NA is also discontinued. Both configurations have eight Gigabit access ports and two 1G combo uplinks. The current model suits new standardization; the older model remains a like-for-like reference for installed fleets.
MGBSX1 and MGBLX1 are fiber transceiver options for the 350 Series Gigabit combo uplinks. MGBSX1 uses 850 nm multimode fiber for links up to 500 m; MGBLX1 uses 1310 nm single-mode fiber for links up to 10 km. Match the remote receiver, wavelength, and installed fiber before selecting the part number.
SG350-10-K9-NA provides 20 Gbps switching capacity and 14.88 Mpps forwarding for 64-byte packets. A 1.5 MB packet buffer is dynamically shared across ports, and the MAC table supports 16000 addresses. STP/RSTP/MSTP provide loop control, while LACP handles link aggregation; these functions do not create a hardware stack.
