SG350-28MP-K9-UK is a managed Layer 2+ Gigabit PoE+ switch with 24 copper access ports and fixed 1G uplinks for small-business networks. Two dedicated SFP interfaces and two copper/SFP combo pairs provide fiber or copper attachment without a removable uplink module. The Cisco 350 Series Managed Switches family serves office connections for IP phones, wireless access points, and other Ethernet devices, with this model occupying 1U in a standard rack. The discontinued SG350-28P-K9-UK restricts endpoint power allocation to 195W, distinguishing the MP variant when the powered-device list needs a larger allocation. Each combo connection selects one physical medium at a time; specify the fiber and copper layout rather than treating both sides as independent links. This Cisco Small Business switch uses integrated AC power rather than an external desktop adapter.

56 Gbps switching capacity supports wire-speed, nonblocking operation across the fixed interfaces. 41.66 Mpps forwarding applies to 64-byte packets, giving a separate figure for checking small-packet workloads. 382W of shared PoE power sets the combined endpoint delivery ceiling rather than guaranteeing maximum power on every port simultaneously. Static IPv4 routing and PBR support routed segmentation with 990 static routes and 128 IP interfaces. SG350-28MP-K9-UK has 512 MB of DRAM for its embedded management functions, while 256 MB of flash accommodates software storage. The 1.5 MB packet buffer is dynamically shared across ports rather than reserved separately for each connection. STP/RSTP/MSTP provide loop control, and LACP supports link aggregation without changing the physical speed of individual links. DHCP snooping and Dynamic ARP Inspection check address bindings on access traffic. The browser interface offers simple and advanced configuration modes. The fixed uplink hardware does not provide a 10G upgrade path.
SG350-28MP-K9-UK is available new sealed or certified refurbished; ORM provides up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units, with 30-day returns on every condition, terms apply. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, optics bay recognition checked, firmware verified, and configuration wiped to factory default. Specify condition, regional power cord requirements, and fiber connections on the purchase order. Cisco's limited lifetime hardware warranty ends October 31, 2026; POs are accepted, government buyers receive Net-30, and enterprise or volume orders have regional stock/RMA across UK, EU, US, and MEA with advance replacement.

When adding endpoints that need more than standard PoE+ power, four access ports can deliver 60W each; the other powered ports have 30W ceilings. These individual limits remain subject to the combined switch allocation. Identify the high-draw devices, assign their connections, and establish simultaneous demand before the PO.
When standardizing configurations across multiple sites, editable text configuration files and Secure Copy downloads support a common staging workflow. CLI privilege levels 1, 7, and 15 separate operator access for that rollout. Establish the configuration baseline and assign administrative privileges before placing the PO for each site.
When preparing troubleshooting or acceptance hardware, port mirroring can send traffic from eight source ports to one destination port within a single session. The test plan therefore needs to identify which connections will be observed together. Reserve the analyzer connection and define mirror sources before ordering the staging hardware.
10G uplinks to distribution
SG350-28MP-K9-UK limits its fixed uplinks to 1G. C1300-24FP-4X retains 24 Gigabit access ports and provides four 10G SFP+ uplinks for the higher-speed connection requirement.
Fanless cooling in occupied rooms
SG350-28MP-K9-UK uses two cooling fans, so the chassis does not meet a fanless requirement. Specify fanless cooling where active fans are excluded by the installation requirements.

SG350-28MP-K9-UK identifies the 350 Series Gigabit managed configuration with 28 logical ports: 24 PoE+ access ports and four Gigabit uplinks. MP distinguishes the 382W PoE-budget variant; UK selects the regional ordering version for the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia.
SG350-28MP-K9-UK supports HTTP/HTTPS web management, Textview CLI through console, SSH or Telnet, and SNMP versions 1, 2c, and 3. Network-level options include Smart Network Application, FindIT Network Manager with an embedded FindIT Network Probe, and Cisco Active Advisor. Browser management offers simple and advanced modes; CLI operators can use full or menu-based commands.
SG350-28MP-K9-UK has a 382W shared PoE budget across 24 powered access ports. Four ports support 60W PoE; the remaining powered ports have 30W ceilings. Total delivery stops at the shared budget, so specify simultaneous endpoint demand rather than assuming all ports can supply their individual maximums at once.
SG350-28MP-K9-UK has fixed 1G uplinks: two dedicated SFP ports and two Gigabit copper/SFP combo pairs. Each combo pair operates as one copper connection or one fiber connection at a time. These are built-in interfaces, not a removable uplink card; specify the intended medium for each combo pair on the order.
SG350-28MP-K9-UK supports static IPv4 routing and PBR with 990 static routes and 128 IP interfaces. Routed interfaces can be physical ports, LAGs, VLAN interfaces, or loopbacks, and the bridge supports 4094 VLANs. This configuration is Layer 2+. Establish next hops and allocate interfaces before commissioning connections between routed segments.
Yes, the Cisco SG350-28MP is a 440 mm-wide, 44 mm-high rack-mount switch occupying 1U. Its 257 mm depth and 3.37 kg weight matter for cabinet layout and handling. The original package includes a mounting kit; specify the required rack hardware and condition on the purchase order to confirm supplied accessories.
SG350-28MP-K9-UK accepts 100-240V AC through its internal universal power supply at 50-60 Hz. The original package includes a power cord rather than an external adapter for this model. Confirm the regional cord requirement for the installation site, particularly when ordering the UK regional version for use outside its designated markets.
SG350-28MP-K9-UK is offered new sealed or certified refurbished, with ORM warranties of up to 3-year extended and up to 1 year, respectively. Cisco's limited lifetime hardware warranty is bounded by October 31, 2026. Every condition includes 30-day returns, terms apply; refurbished managed units are firmware verified and wiped to factory default.
Yes, SG350-28MP-K9-UK is discontinued, with end-of-sale on October 30, 2021 and last support on October 31, 2026. Software maintenance ended October 30, 2022. Its original replacement, CBS350-24FP-4G-UK, was also discontinued, with end-of-sale on October 29, 2024; the current migration path ends at C1300-24FP-4G. Plan service coverage around the SG350 support deadline.
SG350-28MP-K9-UK replaces discontinued SG300-28MP-K9-UK, which reached end-of-sale on August 2, 2018. Cisco support for that older part ended August 31, 2023. The SG350 model is also discontinued, so replacement planning must distinguish an existing-model spare purchase from migration to the current C1300-24FP-4G.
SG350-28MP-K9-UK provides a 382W shared PoE budget, whereas SG350-28P-K9-UK provides 195W. Both models are discontinued members of the 350 Series. The MP variant suits endpoint lists requiring a larger combined power allocation; the P variant suits installations whose simultaneous powered-device requirements fit within 195W. Select against the planned simultaneous load.
SG350-28MP-K9-UK has 24 copper access ports, whereas SG350-52MP-K9-UK has 48. Both models are discontinued 350 Series Gigabit PoE+ switches. The 28MP model matches 24-connection replacement orders; the 52MP model covers 48-connection requirements in one chassis. Match endpoint count to the size of the planned access deployment before selecting the part number.
C1300-24FP-4G provides four dedicated 1G SFP uplinks, whereas SG350-28MP-K9-UK provides two dedicated SFP ports and two copper/SFP combo pairs. SG350-28MP-K9-UK is discontinued and suits existing-model sparing requirements. C1300-24FP-4G is the current migration endpoint and suits replacement purchases requiring four independent fiber uplink interfaces rather than shared copper/fiber connections.
SG350-28MP-K9-UK reaches 451.2W worst-case consumption with PoE at 220V. The worst-case system-only figure at that same voltage is 42.1W. These values separate endpoint delivery from switch operation; size AC circuits and backup power for the combined load rather than using the PoE budget as the input-draw figure.
SG350-28MP-K9-UK uses two cooling fans and is not fanless. Acoustic noise is 37.2 dB between 0°C and 25°C, increasing to 51.8 dB at 50°C. Position the chassis according to temperature and noise requirements, allowing for fan noise to increase at higher ambient temperatures rather than expecting silent operation.
