SG350X-24MP-K9-UK is a managed Layer 2+ access switch with 24 Gigabit Ethernet PoE+ ports and four fixed 10G uplinks for small-business networks. Two uplinks offer shared 10GBASE-T/SFP+ connections, while two provide dedicated SFP+ cages; each shared connection uses copper or fiber, not both simultaneously. The 1U rack chassis belongs to the Cisco 350X Series and connects wired workstations alongside powered IP phones, wireless access points and surveillance cameras. The discontinued SG350X-24P-K9-UK provides a 195W PoE allocation, distinguishing the lower-power sibling from this higher-budget configuration. For copper distribution links, Category 6a cabling supports 10 Gigabit Ethernet connections over distances of 100 m. Fiber connectivity uses the built-in cages rather than a removable uplink card, so the uplink architecture remains fixed when the switch is ordered.

128 Gbps switching capacity accommodates nonblocking traffic across the integrated ports, while 95.23 Mpps forwarding at 64-byte packet size defines the small-packet processing ceiling. 382W of shared PoE output supplies endpoint power through the access interfaces rather than the uplinks. Static IPv4 and IPv6 routing enables inter-VLAN forwarding without dynamic route exchange; the IPv4 routing limit is 990 routes. SG350X-24MP-K9-UK uses 512 MB of memory for running software and 256 MB of flash for stored images, with a 1.5 MB packet buffer shared across ports. STP, RSTP and MSTP handle bridged loop prevention, while LACP groups links for aggregated connections. The SG350X-24MP supports 16000 MAC entries and 4094 active VLANs, separating endpoint learning capacity from segmentation scale. Hardware stacking joins four members under one management address using high-speed copper or fiber interfaces. Local administration uses the browser interface or command line, with SNMP available for monitoring and secure management sessions supported through SSH.
SG350X-24MP-K9-UK is offered new sealed or certified refurbished, with ORM warranty coverage of up to 3 years extended on new units and up to 1 year on certified refurbished units; returns are accepted for 30 days in either condition, and terms apply. Certified refurbished units are inspected and bench-tested, including PoE output under load on every powered port, with firmware verified and configuration wiped to factory default. Specify the required condition, unit quantity and accessory PIDs on the purchase order. ORM accepts POs for enterprise and volume orders, offers Net-30 for government, and provides RMA with advance replacement, with regional stock and RMA in the UK, EU, US and MEA.

When several small-business sites need a common configuration baseline, text-editable configuration files can be transferred to another switch and delivered through SCP. The UK ordering suffix also covers Singapore, Hong Kong and Malaysia. Specify the regional power-cord requirement and the approved configuration file for each destination before issuing the purchase order.
When replacement units must pass acceptance checks before release to production, the front-panel USB Type A slot supports file and image handling, and dual firmware images support upgrade staging. Define the approved image, saved configuration and clean-boot acceptance criteria before the purchase order includes preparation or testing requirements.
When a branch rollout requires local address assignment across several subnets, the switch can serve multiple DHCP pools and supports 128 IPv4 interfaces. Confirm the subnet plan, DHCP scopes and upstream gateway arrangement before release, then include configuration staging requirements with the purchase order rather than assuming factory settings match the site.
Dynamic routing at the access edge
SG350X-24MP-K9-UK supports static IPv4 and IPv6 routing, not dynamic route exchange. A design requiring learned routes needs separate routing equipment with the required dynamic protocols.
Multigigabit speeds on endpoint ports
SG350X-24MP-K9-UK limits every endpoint port to 1Gbps. C1300-24MGP-4X provides eight 2.5GbE ports alongside sixteen Gigabit ports, retaining a total of 24 copper endpoint connections.
Cisco support beyond October 2026
SG350X-24MP-K9-UK reaches its final Cisco support date on October 31, 2026. C1300-24FP-4X is the current successor; the intermediate CBS350-24FP-4X-UK is already discontinued.
60W power on every endpoint port
SG350X-24MP-K9-UK supports 60W on four powered ports; the remaining powered ports support 30W. All endpoints share the overall power allocation, so uniform 60W deployment is unsupported.

SG350X-24MP-K9-UK identifies the UK-region SG350X-24MP configuration in the Cisco 350X family. SG350X identifies the stackable Gigabit range, 24 indicates the access-port count, and MP identifies the 382W PoE configuration. UK also covers Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia.
SG350X-24MP-K9-UK supports an HTTP/HTTPS web interface, full or menu CLI over console, SSH or Telnet, and SNMP management. Additional integrations include Smart Network Application, Cisco FindIT Network Manager, embedded FindIT Network Probe, FindIT Network Discovery Utility, Active Advisor and Cisco Network Plug and Play. Both simple and advanced browser modes are available.
Yes, SG350X-24MP-K9-UK supplies 60W on four PoE ports and 30W on its other powered ports, subject to the 382W shared budget. The access ports support PoE and PoE+, with backward compatibility for Cisco legacy PoE. The 60W capability does not mean all 24 ports can supply 60W simultaneously; endpoint draw must fit the combined allocation.
SG350X-24MP-K9-UK provides four 10G uplink connections: two dedicated SFP+ cages and two copper/SFP+ combo connections. Each combo pair activates one interface at a time. For fiber links, SFP-10G-SR= serves multimode fiber and SFP-10G-LR= serves single-mode fiber; specify the appropriate supported PID against the fiber route before ordering.
Four members form a hardware stack in the Cisco 350X Series, managed as a single system. Ring and chain arrangements use 10G copper or fiber interfaces, with LAG available for interconnect aggregation. Compatible stack families are SG350X, SG350XG and SX350X; SFP-H10GB-CU1M= provides a 1 m copper interconnect option.
Yes, SG350X-24MP-K9-UK routes between VLANs using static IPv4 and IPv6 routes. The switch supports 990 IPv4 static routes and 245 IPv6 static routes, with interfaces configurable on physical ports, LAGs, VLAN interfaces or loopbacks. Dynamic routing is not part of this feature set, so designs requiring learned routes need a separate routing device.
SG350X-24MP-K9-UK reached end of sale on October 30, 2021, and Cisco support ends October 31, 2026. Its direct replacement, CBS350-24FP-4X-UK, is also discontinued, with sales ending October 29, 2024. The forward replacement chain now ends at C1300-24FP-4X for a current purchase.
SG350X-24MP-K9-UK replaces SF550X-24MP-K9-UK, which reached end of sale on June 18, 2020. The predecessor has 24 Fast Ethernet PoE ports, while SG350X-24MP-K9-UK uses Gigabit Ethernet for its 24 access ports. The predecessor's Cisco support ended June 30, 2025, so its original service window has closed.
SG350X-24MP-K9-UK provides a 382W PoE budget, while SG350X-24P-K9-UK offers 195W for the same access-port count. Both models are discontinued. The higher allocation suits a larger combined endpoint load; the lower allocation suits an existing site whose powered devices remain within its smaller budget.
SG350X-24MP-K9-UK has 24 Gigabit access ports, compared with 48 on SG350X-48MP-K9-UK. Both models are discontinued members of the same family. The 24-port configuration suits matching a smaller installed endpoint count, while the 48-port configuration suits an existing installation requiring twice the copper access-port density.
C1300-24FP-4X provides four 10G SFP+ uplinks, whereas SG350X-24MP-K9-UK combines two dedicated SFP+ uplinks with two copper/SFP+ combo connections. The current successor fits all-fiber uplink requirements; the discontinued SG350X configuration preserves copper-or-fiber selection on its shared interfaces for buyers matching an existing installation.
SG350X-24MP consumes 468.8W in the 110V AC worst case with PoE, or 458.4W at 220V AC. Without PoE output, the corresponding system figures are 53.2W and 54.1W. The internal universal supply accepts 100-240V AC; circuit sizing must use the with-PoE figure rather than the system-only value.
ORM offers SG350X-24MP-K9-UK new sealed with up to 3-year extended coverage or certified refurbished with up to 1-year coverage. Cisco's limited lifetime hardware warranty is bounded by its October 31, 2026 support deadline. Both conditions include 30-day returns; terms apply. Refurbished units are inspected and bench-tested, with firmware verified and configuration wiped to factory default.
