SF350-24-K9-EU is a fanless, managed Layer 2+ switch with 24 10/100 Mbps access ports and four fixed Gigabit uplink connections. Two uplinks offer shared RJ-45/SFP media, while two are dedicated SFP slots; each shared pair uses copper or fiber, not both simultaneously. The 1U rack chassis belongs to the Cisco 350 Series and connects separately powered computers, printers, and voice endpoints without supplying PoE. The discontinued SF350-24P-K9-EU adds PoE+ for powered endpoints. The Cisco SF350-24 serves small-business access networks that need managed segmentation while retaining existing endpoint speeds and local power arrangements. Copper and fiber connections can be selected independently for the upstream links.

12.8 Gbps switching capacity supports nonblocking traffic across the interfaces, while 9.52 Mpps forwarding applies to 64-byte packets. 990 static IPv4 routes and 128 IP interfaces support local communication between subnets. STP/RSTP/MSTP provide loop control, and LACP supports eight aggregation groups with eight active ports per group. SF350-24-K9-EU uses 512 MB of DRAM and 256 MB of flash, with a 1.5 MB packet buffer dynamically shared across ports. Administration includes HTTP/HTTPS web configuration, a full or menu-based CLI, and SNMP versions 1, 2c, and 3. SSH, Telnet, and the RJ-45 console provide command-line access. DHCP snooping, IP Source Guard, and Dynamic ARP Inspection check address assignments and source identities. IPv6 forwarding and PBR extend traffic handling beyond basic bridging. 10.9W worst-case system consumption at 220V AC supplies the power-planning figure without an endpoint-power allocation. Hardware stacking is not supported; network-level management does not combine units into one forwarding system.
Order SF350-24-K9-EU in new sealed or certified refurbished condition, stating the quantity and required accessories on the PO. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, a clean boot, and optics bay recognition; firmware is verified and configuration is wiped to factory default. ORM provides new hardware with up to a 3-year extended warranty, certified refurbished hardware with up to a 1-year warranty, and 30-day returns on every condition, terms apply; Cisco's separate limited lifetime hardware warranty is subject to eligibility and ends January 31, 2028. For enterprise and volume orders, ORM accepts POs, offers Net-30 for government and RMA with advance replacement, and supports regional stock and RMA across the UK, EU, US, and MEA.

When several sites need consistent configuration and administrative access, text-editable configuration files and SCP autoconfiguration allow a common baseline to be reused. CLI privilege levels 1, 7, and 15 separate operator permissions. Define the configuration template, authorized administrative roles, and file-transfer method on the purchase request before ordering.
When a change program requires staging before equipment reaches a site, dual software images and front-panel USB Type-A file handling support preparation. A single port-mirroring session can copy traffic from eight source ports for validation. Specify the staging image, test topology, and acceptance capture requirements before the purchase order.
When a branch rollout separates staff, guests, and voice endpoints, private VLANs and automated voice VLAN assignment provide different endpoint policies. Eight hardware QoS queues supply traffic-priority controls without changing link speeds. Specify endpoint grouping, permitted communication between groups, and the voice classification policy before the purchase order.
Gigabit speeds on every access port
The 24 access ports stop at 100 Mbps; Gigabit connectivity is limited to uplinks. C1300-24T-4G provides 24 Gigabit access ports and four 1G SFP uplinks.
Power delivery to endpoint devices
The access ports provide data only and cannot power phones or access points. C1300-24P-4G supplies PoE across 24 Gigabit access ports rather than Fast Ethernet connections.
10G uplinks to distribution
The fixed uplinks operate at 1G, with no 10G uplink option. C1300-24T-4X combines 24 Gigabit access ports with four 10G SFP+ uplinks; access speed also changes.

SF350-24-K9-EU identifies a Cisco 350 Series Fast Ethernet managed switch with 24 access ports and the EU regional suffix. SF350 names the model group, and 24 indicates the access-port count. The full regional identifier selects the non-PoE configuration with two Gigabit combo uplinks and two dedicated SFP uplinks.
SF350-24-K9-EU supports HTTP/HTTPS web management, full or menu-based CLI access through the RJ-45 console, SSH or Telnet, and SNMP 1/2c/3. Network-level options include Smart Network Application, Cisco FindIT Network Manager with an embedded probe, and Cisco Active Advisor integration. These management capabilities do not provide hardware stacking.
Yes, SF350-24-K9-EU is discontinued: end of sale was January 29, 2023, and the last date of support is January 31, 2028. Software maintenance ended January 29, 2024. A purchase from remaining reseller inventory does not restart Cisco's maintenance or service milestones.
ORM Systems offers SF350-24-K9-EU new sealed with up to a 3-year extended warranty or certified refurbished with up to a 1-year warranty. Both conditions include 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty remains subject to entitlement and cannot extend beyond January 31, 2028.
SF350-24-K9-EU replaces the discontinued SRW224G4-K9-EU, sold as the SF300-24 with 24 10/100 ports and Gigabit uplinks. The SRW ordering identifier and SF300 model name identify the predecessor, not an SF350 configuration. SF350-24-K9-EU is itself discontinued, so this relationship describes the historical replacement path.
SF350-24-K9-EU has four logical 1G uplinks: two dedicated SFP ports and two RJ-45/SFP combo ports. Each combo pair uses one connection at a time. MGBSX1 supports multimode fiber to 500 m, and MGBLX1 supports single-mode fiber to 10 km. Transceiver selection must match the installed fiber and peer connection.
Yes, SF350-24-K9-EU supports static IPv4 routing with 990 routes and 128 IP interfaces, plus IPv6 routing and PBR. Routing interfaces can be physical ports, link aggregation groups, VLAN interfaces, or loopbacks. Inter-VLAN traffic can remain local when static routes provide the required reachability between configured subnets.
Yes, Cisco SF350-24 fits a standard equipment rack as a 1U switch; the chassis is 440 mm wide, 44 mm high, and 202 mm deep. Unit weight is 2.72 kg. The base package includes a mounting kit, so mounting-hardware inclusion should be confirmed for the quoted condition.
No, Cisco SF350-24 switches do not support hardware stacking. Smart Network Application provides network-level discovery, monitoring, configuration, and software upgrades across devices, but does not create a shared forwarding system. Multiple units remain independently connected switches, each requiring its own uplink connections and configuration management.
Cisco SF350-24 uses an internal 100-240V AC supply and does not require an external power adapter. The fixed supply has no internally redundant PSU option. Worst-case system consumption is 10.6W at 110V AC or 10.9W at 220V AC; these figures cover the switch itself, not endpoint power.
SF350-24P-K9-EU supplies PoE+ from a 185W shared budget, whereas SF350-24-K9-EU provides no endpoint power. Both configurations are discontinued and retain 24 Fast Ethernet access ports. The non-PoE model suits separately powered devices; the PoE+ version suits legacy installations requiring endpoint power within its allocated budget.
SF350-48-K9-EU has 48 Fast Ethernet access ports, whereas SF350-24-K9-EU has 24. Both models are discontinued, so this comparison concerns existing estates rather than a current-generation refresh. The 24-port configuration suits a smaller device set; the 48-port configuration suits a legacy position requiring more access connections.
C1300-24T-4G provides 24 Gigabit Ethernet access ports, whereas SF350-24-K9-EU provides 24 Fast Ethernet ports. The migration path passes through the discontinued CBS350-24T-4G-EU, but C1300-24T-4G is the current target. The older model suits like-for-like legacy replacement; the Catalyst 1300 model suits buyers moving access links to Gigabit Ethernet.
SF350-24-K9-EU operates from 0°C to 50°C and carries UL 60950, CSA 22.2, CE, and FCC Part 15 Class A compliance. Its fanless chassis uses passive cooling, and MTBF is 562313 hours at 40°C. These ratings frame ambient-temperature and site-compliance checks rather than promising a service interval.
