SG350XG-48T-K9-UK is a managed Layer 2+ switch with 46 dedicated 10GBase-T connections and two additional copper/SFP+ combo positions. Its fixed uplink architecture supports fiber connections without an expansion card, but activating either SFP+ cage disables its paired copper connection. The non-PoE design serves independently powered equipment rather than delivering endpoint power. A full-width 1U chassis places this Cisco 350X Series model in a rack-mounted small-business network. The discontinued SG350XG-24T-K9-UK provides 24 copper connections instead, making port density the distinction between these two models. The SG350XG-48T supports both Gigabit and 10 Gigabit operation, allowing existing compatible equipment to remain connected while individual links move to the higher speed.

960 Gbps switching capacity provides a nonblocking fabric across the active interfaces. 714.24 Mpps forwarding performance applies to 64-byte packets, giving packet-rate sizing a separate measure from aggregate bandwidth. Static IPv4 routing supports 990 routes for communication between subnets; routing is static rather than dynamically learned. SG350XG-48T-K9-UK uses 512 MB of DRAM and 256 MB of flash for switch operation and image storage. A dynamically shared 4 MB packet buffer serves traffic across the ports, while the address table accommodates 32000 MAC entries. STP/RSTP/MSTP support loop-control configurations, and LACP combines compatible links. Administration includes a browser interface, CLI access and SNMP monitoring, with a dedicated Gigabit out-of-band management connection. 272.6W maximum consumption at 110V AC provides the upper input-power figure for circuit planning. Four fans cool the chassis within its 0°C to 50°C operating range, so cabinet ventilation remains part of installation planning.
Order SG350XG-48T-K9-UK new sealed or certified refurbished; ORM's new warranty is up to a 3-year extended term, refurbished coverage is up to 1 year, and both conditions include 30-day returns, terms apply. Refurbished units are inspected and bench-tested, including rated-speed port links, optics bay recognition, PSU and fan status, clean boot, firmware verification and configuration wiping to factory default. Specify condition, quantity and accessories on the purchase order; Cisco's limited lifetime hardware warranty and service ended June 30, 2025. Enterprise and volume orders support POs, government Net-30 and RMA with advance replacement across the UK, EU, US and MEA.

When a site is extending copper connectivity to additional equipment, the cabling specification becomes part of the switch purchase. Category 6a supports 10 Gigabit Ethernet connections over distances reaching 100 m. Include patching, cable qualification and the required link lengths in the installation scope before issuing the purchase order.
When an existing network needs additional routed interfaces, interface and address-family limits should be checked separately from physical port availability. The switch supports 128 IP interfaces, plus 245 IPv6 static routes and 106 IPv6 interfaces. Check the proposed interface inventory and IPv6 routing requirements before specifying the configuration.
When one purchasing program serves several countries, the UK ordering suffix covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia. Regional naming should remain consistent across equipment requests and delivery instructions. Specify the destination country and required power-cord arrangement before releasing each purchase order.
Endpoint power over Ethernet
The copper ports do not supply PoE, so attached powered devices require independent power. This model cannot replace a PoE access switch without changing endpoint power arrangements.
Copper ports plus independent fiber uplinks
Only two shared SFP+ positions are available, and each replaces a copper connection. A requirement for 48 active copper links plus independent fiber uplinks exceeds this hardware's connection layout.
Active Cisco service coverage
Cisco support ended June 30, 2025. The replacement line also ends in a discontinued model without a current successor, so this switch cannot satisfy purchasing requirements for active Cisco service.

SG350XG-48T-K9-UK identifies the regional order code for a Cisco 350X stackable managed switch with 48 10GBase-T ports. SG350XG-48T is the model name, while UK selects the regional version covering the United Kingdom and six additional markets. Two copper positions share their connections with SFP+ cages.
SG350XG-48T-K9-UK supports an HTTP/HTTPS web interface, full or menu CLI through console, SSH or Telnet, and SNMP v1/v2c/v3. Network-level options include Smart Network Application, FindIT Network Manager with an embedded FindIT Network Probe, and Active Advisor. Network Plug and Play with PnP Connect supports provisioning; a dedicated Gigabit management port separates administration traffic.
SG350XG-48T-K9-UK is discontinued, and Cisco support ended June 30, 2025. End of sale occurred June 18, 2020, followed by the end of software maintenance on June 18, 2021. Purchasing remaining inventory does not restart these milestones or restore Cisco service eligibility.
Yes, SG350XG-48T-K9-UK supports static routing between VLANs, with 990 IPv4 static routes and 128 IP interfaces. IPv6 static routing supports 245 routes and 106 IPv6 interfaces. Routing interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopback interfaces; routing is not dynamically learned.
SG350XG-48T-K9-UK accepts SFP-10G-SR= for multimode fiber and SFP-10G-LR= for single-mode fiber. Supported direct-attach cables include SFP-H10GB-CU1M=, SFP-H10GB-CU3M= and SFP-H10GB-CU5M= for 1 m, 3 m and 5 m connections respectively. Each SFP+ connection occupies a combo position and disables its paired copper interface.
Cisco 350X true stacking combines four members into one managed system. Compatible members include SG350X, SG350XG and SX350X switches, with ring or chain connections over suitable network interfaces. SFP-H10GB-CU1M=, SFP-H10GB-CU3M= and SFP-H10GB-CU5M= provide supported direct-attach cable choices; reserve the selected interfaces when planning endpoint connections.
SG350XG-48T occupies 1U in a full-width rack installation and measures 440 mm wide, 44 mm high and 450 mm deep. The switch weighs 7.43 kg. A mounting kit is included in the original package; verify the mounting hardware and cabinet depth when specifying the order.
SG350XG-48T-K9-UK draws a maximum of 272.6W at 110V AC; the corresponding 220V AC figure is 258.2W. Its internal universal AC input accepts 100-240V AC. Four fans provide active cooling, so power and cabinet ventilation planning should use the operating conditions rather than treating the switch as fanless.
SG350XG-48T-K9-UK originally migrated to SX350X-52-K9-UK, which is also discontinued. That model subsequently migrated to CBS350-48XT-4X-UK, another discontinued switch with 48 copper ports and four dedicated SFP+ connections. The replacement line has no current successor, so neither intermediate model should be treated as a current-production alternative.
SG350X-48P-K9-UK provides PoE+ endpoint power, whereas SG350XG-48T-K9-UK does not supply PoE. Both switches are discontinued. The powered model has a 382W shared PoE budget; the non-PoE model suits independently powered equipment, while the powered model addresses installations that need endpoint power over network cabling.
SG350XG-48T-K9-UK provides 48 copper connections, compared with 24 on SG350XG-24T-K9-UK. Both switches are discontinued, and both include two SFP+ positions shared with copper connections. The larger model serves higher connection counts; the smaller model suits installations whose copper-port requirement remains within its lower density.
SG350XG-48T-K9-UK is copper-focused, while SG350XG-24F-K9-UK provides 24 SFP+ connections, including two positions shared with copper. Both models are discontinued. The copper model serves twisted-pair connections; the fiber model suits optical connections and also has a lower total network-port count, which changes the required equipment quantity.
ORM Systems offers SG350XG-48T-K9-UK new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Every condition includes 30-day returns; terms apply. Refurbished units are inspected and bench-tested, with firmware verified and configuration wiped to factory default. Cisco's original limited lifetime hardware warranty and service ended June 30, 2025.
