SG350XG-24F-K9 concentrates 10 Gigabit fiber connections for small-business server, storage, and backbone networks in a managed Layer 2+ switch. The 350X chassis provides 22 dedicated SFP+ network ports and two fixed combo uplinks, each offering either SFP+ or 10GBASE-T connectivity rather than an additional simultaneous connection. No PoE output is available, so attached equipment requires its own power. A full-width 1U enclosure places the Cisco SG350XG-24F in the equipment rack, with an internal AC supply instead of an external adapter. The discontinued SG350XG-24T-K9-NA reverses the media emphasis, carrying copper network ports with shared fiber alternatives. This fiber-oriented configuration serves optical aggregation without a removable uplink-card purchase.
SG350XG-24F-K9 price for new stock is $4,817.40. SG350XG-24F-K9 refurb price is $1,270.50. SG350XG-24F-K9 is in stock and available for next-day dispatch. (terms applied)

480 Gbps switching capacity supports nonblocking switching across the network interfaces, while 357.12 Mpps forwarding handles 64-byte packets. Static IPv4 and IPv6 routing provides inter-VLAN forwarding without a dynamic routing feature set. SG350XG-24F-K9 carries 512 MB of DRAM and 256 MB of flash for its embedded software and configuration, alongside a 32000-entry MAC table. A 2 MB packet buffer is shared dynamically across ports rather than reserved per interface. STP, RSTP, and MSTP govern loop prevention; LACP combines links, and eight hardware queues apply traffic prioritization. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection enforce address-binding checks, while 2000 ACL entries support traffic filtering. Management choices include the browser interface, console CLI, SSH, Telnet, and SNMP, with Smart Network Application and FindIT tools available for network-level administration. 50.4W worst-case draw establishes the maximum chassis load for circuit planning. Four fans provide cooling within the operating temperature range.
ORM Systems supplies SG350XG-24F-K9 new sealed or certified refurbished; specify the condition, regional cord, and connection media on the PO. Refurbished units are inspected and bench-tested, including optics bay recognition, with firmware verified and configuration wiped to factory default. New units carry up to 3-year extended ORM warranty coverage and certified refurbished units up to 1 year; 30-day returns cover both conditions, terms apply, while Cisco's original limited lifetime warranty service ended June 30, 2025. Enterprise and volume purchasing supports PO acceptance, government Net-30, and RMA with advance replacement across UK, EU, US, and MEA regions.

When extending an existing mixed-speed stack, SG350X, SG350XG, and SX350X members can share a unified system. Ring or chain interconnects use network interfaces, so those connections compete with endpoint cabling. Specify the participating models and interconnect media, then reserve stacking connections before approving the hardware quantity.
When a branch segmentation plan creates many gateway interfaces, the switch supports 128 IP interfaces and 106 IPv6 interfaces, with IPv6 limited to 245 static routes. Those limits are separate from physical port availability. Count interfaces and IPv6 routes in the intended configuration before releasing the PO.
Before a staged cutover, configuration and image files can be transferred through front-panel USB Type A, while dual software images support upgrade preparation. Traffic from eight source ports can be mirrored to one destination during testing. Specify the configuration baseline, capture connection, and rollback image with the staging order.
Cisco-backed service for new deployments
Cisco service for SG350XG-24F-K9 ended June 30, 2025. C1300-24XS is the current migration endpoint for buyers whose procurement requirements exclude unsupported hardware.
Power delivery to connected endpoints
SG350XG-24F-K9 provides no PoE output, so connected endpoints require independent power. Endpoint powering cannot be added by selecting different optics or activating a software feature.
Dynamic routing between network segments
SG350XG-24F-K9 supports static IPv4 and IPv6 routing rather than a dynamic routing feature set. Networks requiring dynamically learned routes need an alternative with dynamic routing support.

SG350XG-24F-K9 identifies the SG350XG model with 24 ten-gigabit SFP+ ports, including two shared copper combinations. The 24F portion corresponds to that fiber-port configuration; K9 remains part of the complete order code. Regional forms include SG350XG-24F-K9-NA for the United States and SG350XG-24F-K9-EU for EU markets.
SG350XG-24F-K9 is managed through an HTTP/HTTPS web interface, a full or menu CLI over console, SSH or Telnet, and SNMP versions 1, 2c and 3. Network-level options include Smart Network Application, FindIT Network Manager and Probe, FindIT Network Discovery Utility, Active Advisor, and Cisco Network Plug and Play with PnP Connect.
No, SG350XG-24F-K9 passed its last date of Cisco support on June 30, 2025. Cisco sales ended June 18, 2020, and software maintenance ended June 18, 2021. Remaining hardware purchases are legacy inventory; the current migration endpoint is C1300-24XS rather than either discontinued intermediate generation.
ORM offers SG350XG-24F-K9 new sealed with up to 3-year extended coverage or certified refurbished with up to 1 year. Returns are available for 30 days in either condition; terms apply. Cisco's original limited lifetime hardware warranty no longer provides service: manufacturer support ended June 30, 2025.
SG350XG-24F-K9 has 24 usable network connections: 22 dedicated SFP+ ports and two combo connections offering SFP+ or 10GBASE-T. Each combo connection activates only one medium at a time, so the two RJ-45 sockets do not increase the total to 26. A separate Gigabit port handles out-of-band management.
Yes, the Cisco 350X supports hybrid stacks mixing SG350X, SG350XG, and SX350X models, with four members managed as one system. Ring and chain topologies are supported, and network interfaces carry the stacking interconnects. Allocate those interfaces before finalizing endpoint counts; link aggregation can combine interconnects.
Yes, SG350XG-24F-K9 routes between VLANs using static IPv4 and IPv6 routes, with 990 IPv4 static routes and 128 IP interfaces. IPv6 supports 245 static routes and 106 interfaces. Routing interfaces can be physical ports, link aggregation groups, VLAN interfaces, or loopbacks; this is not a dynamic-routing switch.
SFP-10G-SR= and SFP-10G-LR= support SG350XG-24F-K9 multimode and single-mode fiber links respectively. SFP-H10GB-CU1M=, SFP-H10GB-CU3M=, and SFP-H10GB-CU5M= provide 1 m, 3 m, and 5 m direct-attach copper connections. SFP+ ports also support 1G operation with compatible optics; select media and reach separately from the chassis.
Cisco SG350XG-24F uses an internal universal AC supply accepting 100-240V AC at 47-63 Hz, with four fans for cooling. Worst-case consumption reaches 50.4W at 220V AC, versus 49.5W at 110V AC. Operating temperature is 0°C to 50°C; endpoint power is not supplied through PoE.
SG350XG-24F-K9 uses 24 SFP+ positions with two shared copper alternatives, whereas discontinued SG350XG-24T-K9-NA uses 24 copper positions with two shared SFP+ alternatives. Both offer 24 active network connections, not 26. The fiber-oriented model addresses optical cabling; the copper-oriented model addresses existing twisted-pair connections.
SG350XG-24F-K9 has no PoE output, while discontinued SG350X-24P-K9-NA supplies a shared 195W PoE budget across 24 powered access ports. The latter also uses Gigabit copper access rather than ten-gigabit fiber access. The first addresses independently powered fiber connections; the second addresses powered Gigabit endpoints in legacy networks.
C1300-24XS has four shared 10G copper connections rather than the two on SG350XG-24F-K9 and is the current migration endpoint. Both provide 24 SFP+ positions, with shared media counted once. The legacy model addresses an accepted installed-base requirement; C1300-24XS addresses migration away from unsupported hardware.
Yes, the Cisco SG350XG-24F fits a standard equipment rack as a 1U chassis measuring 440 mm wide, 44 mm high, and 350 mm deep. The chassis weighs 4.16 kg, and the original package includes mounting hardware. Allow ventilation for the four-fan cooling system when planning the rack installation.
Cisco 350X supports STP, RSTP, MSTP, and LACP for loop control and link aggregation, together with VLAN segmentation and hardware traffic prioritization. SG350XG models provide eight hardware queues and 2000 ACL entries. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection control unauthorized address use at the access edge.
