SF350-24-K9-UK combines fanless operation with 24 Fast Ethernet access ports and four fixed Gigabit uplinks. Two uplinks are dedicated SFP slots, while two use copper/SFP combo connections with one medium active per connection. The non-PoE, Layer 2+ switch belongs to the Cisco 350 Series Managed Switches and uses a full-width 1U rack-mount chassis. Its access interfaces serve computers, printers, and separately powered equipment where existing endpoint connections remain at 10/100 Mbps. The discontinued SF350-24P-K9-UK sibling adds endpoint power through a shared 185W PoE budget. For a retained Fast Ethernet installation, the distinction is whether the replacement must deliver data alone or also power attached devices. The Gigabit uplinks do not change the native speed of the access ports.

12.8 Gbps switching capacity accommodates traffic across the access and uplink interfaces, while 9.52 Mpps forwarding describes packet handling with 64-byte packets. Static IPv4 routing supports 990 routes, and PBR selects different next hops using IPv4 or IPv6 access policies. SF350-24-K9-UK carries 512 MB of DRAM and 256 MB of flash. Its dynamically shared 1.5 MB packet buffer handles traffic across the ports, while eight hardware queues support traffic scheduling. STP/RSTP/MSTP provides loop prevention, and LACP supports link aggregation. Browser configuration and Textview CLI provide administration, with SNMP available for centralized monitoring. An internal AC supply accepts 100–240V AC input without an external adapter. The maximum system consumption is 10.9W at 220V, providing a power-planning figure without an endpoint PoE load. Uplink connectivity is fixed rather than expandable through removable network cards.
Order SF350-24-K9-UK new sealed or certified refurbished, specifying condition, quantity, and required mounting hardware on the purchase order. Certified refurbished units are inspected and bench-tested for rated-speed port links, optics bay recognition, and PSU status, with firmware verified and configuration wiped to factory default. ORM warranties provide up to a 3-year extended term for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply. Cisco's separate limited lifetime hardware warranty is bounded by its January 31, 2028 support end; enterprise and volume POs are accepted, with Net-30 for government and RMA with advance replacement.

When a failed SRW224G4-K9-UK needs replacement without changing endpoint links, this model is its named migration option. Treat the migration as a configuration project rather than assuming a saved file can be reused unchanged. Include configuration review, staging, and acceptance checks in the replacement purchase.
For a branch rollout using repeatable settings, text-editable configuration files and SCP autoconfiguration support a common staging process. Cisco Network Plug and Play provides another provisioning path. Define the baseline configuration, credential handling, and provisioning method before releasing quantities across the rollout purchase order.
When a lab or staging bench must capture traffic before deployment, port mirroring allows eight source ports to feed one destination in a single session. Select the capture endpoint and traffic sources in advance, and specify the required test connections alongside the switch order.
Gigabit connections to every endpoint
The access ports stop at 100 Mbps. C1300-24T-4G is the current forward replacement with 24 Gigabit Ethernet access ports and four 1G SFP uplinks.
Switch power for attached endpoints
The access ports do not deliver PoE. C1300-24P-4G is the current powered replacement, also changing the access connections from Fast Ethernet to Gigabit Ethernet.

SF350-24-K9-UK identifies a regional order for a 350 Series managed switch with 24 Fast Ethernet ports. SF350-24-K9 is the base order identifier, 24 denotes the access-port count, and UK selects the regional group covering the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia.
SF350-24-K9-UK supports an HTTP/HTTPS web interface, Textview CLI through the console or SSH/Telnet, and SNMP versions 1, 2c, and 3. Network-level options include Cisco Smart Network Application, FindIT Network Manager with its embedded Probe, FindIT Network Discovery Utility, and Cisco Active Advisor. Specify the management method and credentials during staging.
SF350-24-K9-UK provides four 1G uplink connections: two dedicated SFP slots and two copper/SFP combo ports. Only one medium per combo connection can operate at a time. MGBSX1 supports multimode fiber, while MGBLX1 supports single-mode fiber. Choose the transceivers and matching media for the intended link.
The Cisco 350 Series supports static IPv4 routing with 990 routes and 128 IP interfaces, plus PBR for IPv4 or IPv6 traffic selection. Include the required next hops, VLAN interfaces, and access policies in the configuration plan. Check planned interface and route counts before the hardware order is approved.
SF350-24-K9-UK uses an internal AC power supply accepting 100–240V AC input. An external power adapter is not required, and maximum system consumption is 10.9W at 220V. Specify the required regional power cord when confirming order contents, and include the switch's consumption in the site's power allocation.
SF350-24-K9-UK reached end of sale on January 29, 2023, and its last date of Cisco support is January 31, 2028. Software maintenance ended January 29, 2024. The intermediate replacement CBS350-24T-4G-UK is also discontinued; the forward replacement chain now ends at C1300-24T-4G.
SF350-24-K9-UK replaces SRW224G4-K9-UK, the SF300-24 managed Fast Ethernet switch with Gigabit uplinks. Treat the two units as different devices when preparing configuration files and installation instructions. Specify the exact replacement part number, and include review of the existing settings and acceptance tests in the work order.
SF350-24P-K9-UK adds a shared 185W PoE budget where SF350-24-K9-UK supplies data connectivity without endpoint power. Both models are discontinued. The non-PoE model suits retained, separately powered endpoints; the powered sibling matches an existing PoE installation, while C1300-24P-4G is the current forward replacement for a new powered-switch purchase.
SF350-48-K9-UK has 48 Fast Ethernet access ports, compared with 24 on SF350-24-K9-UK. Both models are discontinued, so the comparison concerns existing estate requirements rather than current-generation ordering. The 24-port model fits a replacement with fewer terminated connections; the 48-port model matches a higher-density installed configuration.
C1300-24T-4G provides 24 Gigabit Ethernet access ports where SF350-24-K9-UK provides 24 Fast Ethernet access ports. The replacement chain passes through the discontinued CBS350-24T-4G-UK. Choose the older model only for a deliberate legacy replacement requirement; the current successor suits buyers specifying Gigabit links to endpoints.
ORM Systems offers SF350-24-K9-UK new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Both conditions include 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is separate, with applicable service ending January 31, 2028.
The Cisco SF350-24 uses a full-width 1U rack-mount chassis measuring 440 mm wide, 44 mm high, and 202 mm deep. Its weight is 2.72 kg. A mounting kit is included in the standard package; specify the required mounting hardware when confirming the ordered unit's contents.
