SF350-48-K9-UK is a fanless, managed Layer 2+ switch with 48 10/100 access ports and four fixed Gigabit uplinks, combining two dedicated SFP cages with two copper/SFP combo ports. The rack-mount 1U design belongs to the Cisco 350 Series and serves small-business networks retaining Fast Ethernet endpoints. This non-PoE configuration carries data without supplying endpoint power, so attached phones, access points or cameras require independent power. The discontinued SF350-48P-K9-UK adds PoE+ ports for installations requiring powered connections. Each combo uplink uses either its copper connection or its SFP cage, not both simultaneously, and the fixed uplink arrangement cannot be expanded through a removable network module.

17.6 Gbps switching capacity provides nonblocking traffic handling, while 13.09 Mpps forwarding describes performance with 64-byte packets. Static IPv4 routing supports 990 routes and 128 IP interfaces for communication between subnets; dynamic routing is not included. SF350-48-K9-UK carries 512 MB of memory and 256 MB of flash for its embedded software and saved configuration. A shared 3 MB packet buffer accommodates traffic bursts across the ports, and the address table holds 16000 MAC entries. The Cisco SF350-48 supports 4094 simultaneous VLANs, with STP, RSTP and MSTP handling loop avoidance and LACP grouping links. Browser-based administration, SSH and SNMP provide local and remote management paths. 24.2W maximum system draw at 220V establishes the load to allow for in power planning, while the internal supply accepts 100-240V AC.

When replacing the discontinued SRW248G4-K9-UK, SF350-48-K9-UK is its direct replacement. The older part reached end of sale on August 2, 2018. Keep the replacement scope separate from a bandwidth upgrade, and confirm the existing copper and fiber connections before finalizing the bill of materials.
When multiple sites need the same configuration baseline, editable configuration files can be downloaded to another switch, and Textview CLI supports privilege levels 1, 7 and 15. Separate common settings from site-specific addressing, then specify administrative access and the configuration file to be applied before the purchase order.
When a staging bench must inspect traffic before deploying a replacement, port mirroring can copy eight source ports to one destination through a single session. Identify the capture connection and source ports in advance, then specify the required staging configuration and associated cabling before the purchase order.
Gigabit connections on every access port
SF350-48-K9-UK limits its access ports to 100 Mbps. C1300-48T-4G provides 48 Gigabit access ports and is the current replacement-chain endpoint for orders requiring faster endpoint connections.
PoE power for attached endpoints
SF350-48-K9-UK supplies no endpoint power. C1300-48P-4G adds PoE and Gigabit access; specify that current model when powered endpoints and faster copper access are both required.

SF350-48-K9-UK identifies a 48-port Fast Ethernet managed switch in the Cisco 350 Series, with Gigabit uplinks. SF350-48-K9 is the hardware ordering identifier; 48 denotes the access-port count. The UK suffix selects the regional version covering the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia.
SF350-48-K9-UK supports browser management over HTTP/HTTPS, Textview CLI through console or SSH/Telnet, and SNMP. Network-level options include Smart Network Application, FindIT Network Manager with its embedded probe, and Cisco Active Advisor. Select the supported local or network-management workflow before specifying configuration and monitoring requirements.
SF350-48-K9-UK reached end of sale on July 30, 2022, with Cisco support ending July 31, 2027. Software maintenance ended July 30, 2023. The original replacement, CBS350-48T-4G-UK, is also discontinued; the current migration endpoint is C1300-48T-4G. Distinguish remaining hardware availability from ongoing manufacturer software maintenance when planning an order.
SF350-48-K9-UK is offered new sealed or certified refurbished, with ORM warranties up to 3 years extended for new units or up to 1 year refurbished. Returns are 30 days on every condition; terms apply. Cisco's separate Limited Lifetime hardware warranty cannot extend beyond July 31, 2027.
SF350-48-K9-UK replaces SRW248G4-K9-UK, the SF300-48 managed switch with Gigabit uplinks. The older part reached end of sale on August 2, 2018, and Cisco support ended August 31, 2023. For a replacement order, match the existing copper connections and fiber uplink arrangement before finalizing accessories.
SF350-48-K9-UK has four Gigabit uplink interfaces: two dedicated SFP ports and two copper/SFP combo ports. Each combo interface activates copper or fiber, not both together. MGBSX1 supports multimode fiber up to 500 m, while MGBLX1 supports single-mode fiber up to 10 km; order the appropriate transceivers separately.
SF350-48-K9-UK supports static IPv4 routing with 990 static routes and 128 IP interfaces, plus IPv6 routing and PBR. The switch can route between VLAN interfaces without requiring an external router for every local subnet. Dynamic routing protocols are not part of this configuration, so plan routes explicitly.
SF350-48-K9-UK uses an internal 100-240V AC power supply without redundant PSU modules. Worst-case system draw is 23.4W at 110V or 24.2W at 220V. The UK regional suffix does not change the universal AC input range; confirm the order's power cord arrangement against the destination outlet.
The Cisco SF350-48 is a rack-mount 1U switch measuring 440 mm wide, 44 mm high and 257 mm deep, with a weight of 3.58 kg. The standard hardware package includes a mounting kit. Check rack depth, cable clearance and the 0°C to 50°C operating range before ordering.
SF350-48-K9-UK provides 17.6 Gbps switching capacity and 13.09 Mpps forwarding with 64-byte packets. These ratings describe switching and packet forwarding rather than endpoint-link speed. Size traffic against the access and uplink connections actually used, particularly when several endpoint groups share the same upstream link.
SF350-48P-K9-UK adds 48 PoE+ access ports and a 382W shared power budget, where SF350-48-K9-UK provides data-only connections. Both are 48-port Fast Ethernet models and both are discontinued. The data-only model serves independently powered endpoints; the PoE model addresses legacy installations needing power delivered through access cabling.
SF350-48-K9-UK uses internal AC power, while SF352-08-K9-UK uses an external AC adapter. The discontinued SF352-08-K9-UK also reduces access density to eight Fast Ethernet ports. The larger model fits rack-based, higher-density replacement requirements; the smaller model suits existing low-density installations already organized around an external adapter.
C1300-48T-4G provides 48 Gigabit access ports, where SF350-48-K9-UK provides 48 Fast Ethernet access ports. C1300-48T-4G is the current replacement-chain endpoint after the also-discontinued CBS350-48T-4G-UK. The older, discontinued model suits maintaining 100 Mbps endpoint access; the current model suits orders requiring Gigabit connections at the same density.
