SG350X-48MP-K9-UK combines 48 Gigabit PoE+ access ports with fixed 10G uplinks in a managed Layer 2+ switch for small-business networks. Two uplinks are dedicated SFP+ connections, while two use shared copper/SFP+ combo interfaces, allowing the uplink media to match the installed cabling. The rack-mount 1U chassis belongs to the Cisco 350X Series Stackable Managed Switches and connects wired clients alongside powered phones and wireless access points. The discontinued SG350X-48P-K9-UK provides a lower 382W endpoint-power allocation, distinguishing that model from the MP configuration. Hardware stacking joins four members under one management address. This 48-port Gigabit PoE+ access switch combines endpoint connectivity with a shared control plane rather than treating several independent switches as a management group.

176 Gbps switching capacity supports nonblocking traffic handling, and 130.94 Mpps forwarding applies to 64-byte packets. 740W of shared PoE power must cover the attached devices; eight access ports support 60W PoE, while the remaining powered ports support 30W each. Static IPv4 and IPv6 routing connects local subnets without dynamic route exchange. SG350X-48MP-K9-UK carries 512 MB DRAM and 256 MB flash, with a dynamically shared 3 MB packet buffer for port traffic. STP/RSTP/MSTP controls spanning-tree operation, while LACP forms aggregated links. Administrators can use browser configuration, the Textview CLI, or SNMP for configuration and monitoring, with SSH and HTTPS available for protected management sessions. DHCP snooping and Dynamic ARP Inspection check endpoint addressing against binding information. 890.4W maximum consumption at 110V AC includes PoE loading and sets the upper electrical sizing requirement rather than representing endpoint power alone.
ORM Systems offers SG350X-48MP-K9-UK new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units; returns are available for 30 days in every condition, terms apply. Refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configuration wiped to factory default. Specify condition, quantity, regional power requirements, and accessories on the purchase order; Cisco's separate limited lifetime hardware warranty ends with support on October 31, 2026. For enterprise and volume purchasing, PO accepted, Net-30 for government, and RMA with advance replacement are available, with regional stock and RMA across UK, EU, US, and MEA.

When separate departmental networks are being consolidated, the switch supports 4094 active VLANs and private VLAN isolation for segregating endpoint groups. Treat those features as configuration requirements rather than a substitute for a port plan, and specify the VLAN assignments and segmentation policy before the purchase order.
When multiple sites need repeatable configurations, text-editable configuration files and secure SCP downloads allow approved settings to be prepared for each unit. The embedded PnP agent also supports PnP Connect provisioning. Specify the configuration baseline, management addressing, and staging responsibilities before ordering the site quantities.
When replacement units need staging before entering service, dual software images allow a retained image alongside the staged release, and the front USB Type A slot supports file and image handling. Define the intended image, saved configuration, and acceptance checks before specifying the staging order.
Dynamic routing between network segments
SG350X-48MP-K9-UK supports static IPv4 and IPv6 routing only; deployments requiring dynamic route exchange need routing capability outside this switch rather than an additional software tier.
Silent operation beside occupied desks
SG350X-48MP-K9-UK uses four fans and reaches 53.2 dB at 50°C. A requirement for fanless operation excludes this model from the equipment selection.
Cisco support beyond October 2026
SG350X-48MP-K9-UK reaches its last date of support on October 31, 2026. The onward migration chain leads to C1300-48FP-4X for a lifecycle-led replacement purchase.

SG350X-48MP-K9-UK identifies a 350X Gigabit stackable switch with 48 access ports and the MP 740W PoE configuration. K9 is retained in the complete ordering identifier. UK is the regional suffix for the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia.
SG350X-48MP-K9-UK supports web UI over HTTP/HTTPS, console CLI, SSH, Telnet, SNMP, Smart Network Application, FindIT Network Manager, embedded FindIT Network Probe, FindIT Network Discovery Utility, Active Advisor, and PnP Connect. The Textview CLI provides full and menu modes, while browser management offers simple and advanced modes.
SG350X-48MP-K9-UK provides a shared 740W PoE budget across 48 powered access ports, including eight ports supporting 60W PoE. The other powered ports support 30W each. Individual port limits do not override the shared budget, so total endpoint demand must remain within the available allocation.
SG350X-48MP-K9-UK has four fixed 10G uplinks: two dedicated SFP+ ports and two copper/SFP+ combo ports. Each combo pair permits one active medium. SFP-10G-SR= supports multimode fiber, while SFP-10G-LR= supports single-mode fiber; specify the appropriate optics separately when defining the uplink connections.
The 350X family supports four members in a hardware stack managed as one system, with ring or chain arrangements. SG350X, SG350XG, and SX350X can mix within that stack. Supported copper interconnect options include SFP-H10GB-CU1M=, SFP-H10GB-CU3M=, and SFP-H10GB-CU5M= for 1 m, 3 m, and 5 m connections respectively.
SG350X-48MP-K9-UK supports static IPv4 and IPv6 routing, with 990 IPv4 static routes and 245 IPv6 static routes. Interface limits are 128 for IPv4 and 106 for IPv6. This is Layer 2+ switching with static routing, not a dynamic-routing access switch, so confirm the routing design before ordering.
SG350X-48MP-K9-UK occupies 1U and measures 440 mm wide, 44 mm high, and 450 mm deep, with a weight of 6.69 kg. Check cabinet depth, cable bend space, and mounting hardware on the purchase order rather than assuming that a shallow cabinet will accommodate the chassis.
SG350X-48MP-K9-UK is discontinued: Cisco sales ended October 30, 2021, and the last date of support is October 31, 2026. Software maintenance ended October 30, 2022. The replacement chain passes through discontinued CBS350-48FP-4X-UK and continues to C1300-48FP-4X for migration planning.
SG350X-48MP-K9-UK replaces the discontinued SF550X-48MP-K9-UK, moving that 48-port access configuration from Fast Ethernet to Gigabit Ethernet. The older switch ended sales on June 18, 2020. The 350X replacement is also discontinued, so an upgrade purchase should account for the onward migration chain rather than stop at this generation.
SG350X-48MP-K9-UK provides 740W of PoE power, compared with 382W on SG350X-48P-K9-UK. Both are discontinued. The MP configuration suits an existing design with higher combined endpoint demand; the 48P version addresses lower aggregate draw without changing the access-port count.
SG350X-48MP-K9-UK has 48 Gigabit access ports, while SG350X-24MP-K9-UK has 24. Both models are discontinued members of the 350X family. The higher-density model suits an existing cabinet requiring more endpoint connections; the smaller model suits an installed design built around fewer connections.
SG350X-48MP-K9-UK is discontinued; following its two replacement steps leads to C1300-48FP-4X through the also-discontinued CBS350-48FP-4X-UK. The original switch reaches its last date of support on October 31, 2026. Existing 350X estates may require matching spares, while lifecycle-led refresh purchases should specify the current successor.
The 350X 48-port MP configuration provides 176 Gbps switching capacity and 130.94 Mpps forwarding for 64-byte packets. A 3 MB packet buffer is shared dynamically across the ports rather than reserved as a fixed allowance per connection. Compare offered traffic and burst requirements against those switch-wide resources.
ORM Systems offers SG350X-48MP-K9-UK new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year. Every condition has 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty, with next-business-day advance replacement where available, otherwise same-day shipping, ends with Cisco support on October 31, 2026.
