SF350-24 is a fanless managed Layer 2+ switch with 24 10/100 RJ-45 access ports and four fixed Gigabit uplinks. Two uplinks are copper/SFP combo interfaces, and two are dedicated SFP ports; each combo interface uses either its copper connection or its SFP cage. The non-PoE Cisco 350 Series model carries an internal AC supply in a 1U rack-mount chassis for small-business wired access where endpoints have their own power. The discontinued SF350-24P adds PoE+ with a shared 185W endpoint-power budget, distinguishing powered-device replacement requirements from data-only access.

12.8 Gbps switching capacity and 9.52 Mpps forwarding at 64-byte packet size define the traffic envelope for the fixed interfaces. Static IPv4 and IPv6 routing supports communication between workgroups, while PBR selects next hops using IPv4 or IPv6 ACLs. 990 static IPv4 routes bound the routing configuration and its explicitly assigned next hops. SF350-24 has 512 MB of DRAM and 256 MB of flash for software operation and storage. A dynamically shared 1.5 MB packet buffer serves the ports rather than allocating that amount to each interface. The 350 Series Managed Switches support STP/RSTP/MSTP for loop control. Management includes browser configuration, a scriptable Textview CLI and SNMP, with SSH and HTTPS available for protected sessions. DHCP snooping, IP Source Guard and Dynamic ARP Inspection enforce learned or configured address bindings; port mirroring and cable diagnostics provide troubleshooting tools.
SF350-24 is available new sealed or Certified refurbished; new units carry up to a 3-year extended ORM warranty, and Certified refurbished units carry up to 1 year, with 30-day returns on every condition, terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition and PSU status; firmware is verified and configuration wiped to factory default. Specify condition and quantity on the purchase order for this switch. ORM Systems accepts POs and offers Net-30 for government, RMA with advance replacement, and regional stock and RMA across the UK, EU, US and MEA for enterprise and volume orders.

A mid-size retail chain installs 16 IP cameras across two stores using the SF350-24-8 10/100 ports with 62W power budget, 2 Gigabit copper/SFP combo. Eight cameras draw PoE directly from the switch’s 62W budget, while the remaining cameras connect via non-PoE ports. A Gigabit SFP uplink aggregates video streams to the central NVR. Outcome: simplified wiring, centralized management, real-time security monitoring with minimal infrastructure cost.
A regional bank branch deploys 20 VoIP phones and 4 wireless access points using the SF350-24-8 switch. Eight 10/100 PoE ports power the phones and APs within the 62W budget. Remaining ports serve workstations. Dual Gigabit copper/SFP combos provide redundant uplinks to the core network. Outcome: guaranteed voice quality through QoS, seamless Wi-Fi coverage, reduced power injector costs, and enhanced network resilience.
A university installs 8 ceiling-mounted 802.11ac access points on three floors using the SF350-24-8 10/100 PoE switch. Each AP draws power from PoE ports within the 62W power budget. Non-PoE ports connect IP phones in administration offices. Dual Gigabit SFP uplinks feed data back to the campus core switch. Outcome: rapid-scale Wi-Fi rollout, secure VLAN segmentation per department, centralized switch management, and future-proof fiber connectivity.
When a small-business network is being divided into separately addressed workgroups, the configuration is limited to 128 IP interfaces across physical ports, link aggregation groups, VLAN interfaces and loopbacks. Map the required interfaces and next-hop plan before committing equipment, then specify the intended configuration and interface count with the purchase order.
When several sites need a common loop-control configuration, eight MSTP instances set the available instance count for the 350 Series. Treat the instance requirement separately from endpoint density, record the intended VLAN assignments in the site build standard, and specify the approved spanning-tree configuration before placing the purchase order.
When a replacement switch needs preparation before installation, two firmware images support the upgrade workflow, and front-panel USB accepts image and configuration transfers. Prepare the required settings separately from the live network, record the approved software image, and specify the configuration to load before releasing the unit for deployment.
Gigabit speeds at every endpoint
SF350-24 limits its 24 access ports to 10/100 Mbps. C1300-24T-4G provides 24 Gigabit access ports with four 1G SFP uplinks as the current replacement.
Endpoint power over Ethernet
SF350-24 supplies no PoE on its access ports, so connected powered devices need another power source. A requirement for switch-delivered endpoint power calls for a PoE-capable switch.

SF350-24 identifies a non-PoE Fast Ethernet model in the Cisco 350 Series with 24 access ports. SF350 names the Fast Ethernet branch of the family, while 24 is the access-port count. The model also has four Gigabit uplinks; the North American orderable variant is SF350-24-K9-NA.
The 350 Series supports an HTTP/HTTPS web interface, Textview CLI, console access, SSH and SNMP v1/v2c/v3. Additional tools include Smart Network Application, FindIT Network Manager with an embedded Probe, FindIT Network Discovery Utility and Cisco Active Advisor. Browser configuration offers simple and advanced modes, while the CLI supports scripted administration.
SF350-24 is discontinued: North American sales ended January 29, 2023, and Cisco support ends January 31, 2028. SF350-24-K9-AR, SF350-24-K9-IN and SF350-24-K9-JP ended sale October 30, 2021, with support ending October 31, 2026. Confirm the regional PID when comparing the remaining support period.
ORM Systems offers SF350-24 new sealed with up to a 3-year extended warranty, or Certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's separate Limited Lifetime hardware warranty is bounded by its last support date of January 31, 2028 for the North American variant.
SF350-24 replaces SF300-24 regional models SRW224G4-K9-CN, SRW224G4-K9-EU, SRW224G4-K9-JP, SRW224G4-K9-NA and SRW224G4-K9-UK. In China, SF350-24-K9-CN also replaces SF350-08-K9-CN and SF352-08-K9-CN. The replacement has 24 access ports, so moving from either eight-port China model changes port density and requires checking the endpoint and uplink plan.
SF350-24 provides four 1G uplinks: two dedicated SFP ports and two copper/SFP combo ports. Each combo uses only one medium at a time. For fiber, MGBSX1 serves multimode links to 500 m and MGBLX1 serves single-mode links to 10 km; order the selected transceivers separately.
SF350-24 supports inter-VLAN communication through static IPv4/IPv6 routing and PBR, with 990 static IPv4 routes and 128 IP interfaces. PBR can select different next hops using IPv4 or IPv6 ACLs. The switch is Layer 2+ under this feature set; size the workgroup routing plan against those limits.
SF350-24 uses an internal 100-240V AC power supply rather than an external adapter. Maximum non-PoE consumption is 10.9W at 220V and 10.6W at 110V. The supply does not provide an optional redundant internal module arrangement, so specify the required AC connection rather than a second internal power module.
SF350-24 has no PoE, while the discontinued SF350-24P provides PoE+ with a shared 185W budget. The powered sibling has four ports that support 60W, but available endpoint power remains limited by the total budget. SF350-24 suits independently powered devices; SF350-24P addresses legacy replacements requiring endpoint power.
SF350-24 has 24 Fast Ethernet access ports, while the discontinued SF350-48 has 48. Both retain two Gigabit copper/SFP combo uplinks and two dedicated SFP uplinks. The smaller model matches 24-endpoint replacement plans; the larger model covers legacy sparing requirements where the existing installation needs the higher access-port density.
SF350-24 has 10/100 access ports, whereas C1300-24T-4G provides 24 Gigabit access ports. The migration passes through CBS350-24T-4G-NA, which is also discontinued. SF350-24 serves like-for-like Fast Ethernet replacement orders; C1300-24T-4G is the current replacement when the endpoint plan requires Gigabit connections across all 24 access ports.
