SG350-52MP-K9-UK combines 48 Gigabit PoE+ access ports with managed Layer 2+ switching in a 1U rack-mount chassis. Four fixed 1G uplink connections comprise two dedicated SFP ports and two copper/SFP combo ports, allowing the connection medium to match existing distribution cabling. Eight access ports support 60W PoE for compatible higher-draw devices, alongside powered connections for IP phones, wireless access points and surveillance endpoints. The Cisco 350 Series Managed Switches serve small-business networks rather than modular chassis deployments. The discontinued SG350-52P-K9-UK carries a lower 375W PoE budget for comparison. Local browser-based configuration provides an administration path within the Cisco Small Business line. Uplink expansion is limited to the built-in connections: this model has neither 10G uplinks nor a removable network-card bay.

104 Gbps switching capacity provides nonblocking forwarding across the installed interfaces. 77.38 Mpps forwarding handles traffic at the 64-byte packet benchmark. 740W of shared PoE capacity requires endpoint-level allocation rather than simultaneous maximum output across every powered port. Static IPv4 routing supports 990 routes for inter-VLAN reachability, while PBR selects next hops using IPv4 or IPv6 access-control rules. SG350-52MP-K9-UK uses 512 MB of DRAM and 256 MB of flash for software and configuration handling, with a 3 MB packet buffer dynamically shared across ports. STP, RSTP and MSTP provide spanning-tree operation, while LACP supports aggregated links between network devices. The MAC table accommodates 16000 addresses for local forwarding decisions. 858W worst-case consumption, including PoE, establishes the maximum AC load for power-distribution planning rather than representing endpoint power alone. Four fans provide active cooling within the operating range of 0°C to 50°C. Dynamic route exchange is not part of this switch's routing capabilities.
SG350-52MP-K9-UK is available new sealed or certified refurbished, with ORM warranties of up to 3-year extended coverage for new units and up to 1 year for refurbished units; Cisco's limited lifetime hardware warranty does not extend past October 31, 2026. Refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configurations wiped to factory default. Specify condition, quantity and required optics on the PO; returns are available for 30 days in every condition, terms apply. For enterprise and volume orders, POs are accepted, government buyers receive Net-30 terms, and RMA with advance replacement is available across UK, EU, US and MEA operations.

When a branch needs local address assignment across several network segments, the switch can provide an IPv4 DHCP server and up to 128 IP interfaces. Define address pools, relay boundaries and interface allocation before procurement, then include the required configuration and staging scope on the purchase order.
Where multiple sites need matching configurations, Textview CLI supports scripted administration with privilege levels 1, 7 and 15. Separate operator access from configuration privileges and decide how credentials will be handled during staging. Specify the configuration template, access roles and quantities for each location before releasing the purchase order.
When a replacement must be prepared before a maintenance window, dual firmware images and the front USB Type-A slot support image and file handling. Establish the target firmware and configuration baseline, run cable diagnostics, and specify the required image, configuration files and acceptance checks before ordering the spare.
10G uplinks to distribution
All four uplink connections are limited to 1G. C1300-48FP-4X retains 48 Gigabit access ports and provides four 10G SFP+ uplinks for a faster distribution connection.
Maximum PoE+ on every access port
The shared 740W budget is below 48 × 30W = 1440W, so maximum PoE+ output cannot be allocated to every access port simultaneously.
Automatic exchange of network routes
Routing uses static entries and policy-based next-hop selection rather than dynamic route exchange. Plan a separate routing device where automatically learned routes are mandatory.

SG350-52MP-K9-UK identifies the Gigabit 350-series Max-PoE managed switch in the UK regional ordering form. The 52 denotes 48 access ports plus four uplink connections, while MP distinguishes the Max-PoE model. The UK suffix covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia.
SG350-52MP-K9-UK supports an HTTP/HTTPS web interface, Textview CLI through console, SSH or Telnet, SNMP versions 1, 2c and 3, Smart Network Application, FindIT Network Manager and Cisco Active Advisor. Full-command and menu-based CLI modes are available, and an embedded FindIT Network Probe supports network-level management without a separate probe appliance.
SG350-52MP-K9-UK reached end of sale on October 30, 2021, and its last date of Cisco support is October 31, 2026. Software maintenance ended October 30, 2022. The immediate replacement, CBS350-48FP-4G-UK, is also discontinued; C1300-48FP-4G is the current migration endpoint for buyers comparing legacy continuity with a new installation.
SG350-52MP-K9-UK is offered new sealed or certified refurbished, with ORM coverage of up to 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are available for 30 days in every condition; terms apply. Cisco's limited lifetime hardware warranty does not extend support beyond October 31, 2026.
SG350-52MP-K9-UK replaced SG300-52MP-K9-UK, whose end-of-sale date was October 4, 2018. Cisco support for that older model ended October 31, 2023. A replacement purchase must also account for the SG350 model's own October 31, 2026 support deadline rather than assuming that the newer series restarts manufacturer coverage.
SG350-52MP-K9-UK provides a 740W shared PoE budget across 48 powered access ports, including eight ports supporting 60W. The remaining powered ports support 30W until the total budget is reached. All 48 ports cannot deliver 30W simultaneously because 48 × 30W requires 1440W; size endpoints by their combined allocation.
SG350-52MP-K9-UK has four fixed 1G uplink connections: two dedicated SFP ports and two copper/SFP combo ports. Each combo port activates either its RJ-45 connection or its SFP slot, not both. There is no removable uplink-card bay, and 10G SFP+ uplinks are not available on this model.
SG350-52MP-K9-UK supports static IPv4/IPv6 routing and PBR, with up to 990 static IPv4 routes and 128 IP interfaces. Static routes provide inter-VLAN reachability, while policies select next hops using access-control rules. The switch provides Layer 2+ operation rather than dynamically exchanging routes with neighboring routing devices.
Yes, the SG350-52MP is a 1U rack-mount switch measuring 440 mm wide, 44 mm high and 350 mm deep. The unit weighs 3.83 kg and uses four fans. Account for chassis depth, cable clearance and airflow when assigning rack space and preparing the installation location.
SG350-52MP-K9-UK draws up to 858W at 110V and 833W at 220V when including PoE load. Corresponding worst-case system figures without PoE are 72.5W and 73.6W. Use the combined system-plus-endpoint figure for AC circuit and UPS sizing rather than treating the 740W PoE allocation as wall-power consumption.
SG350-52MP-K9-UK supports MGBSX1 for multimode fiber to 500 m, MGBLX1 for single-mode fiber to 10 km, and MGBLH1 for single-mode fiber to 40 km. GLC-LH-SMD and GLC-BX-U are also supported 1G options. Select the transceiver against fiber type, reach and the equipment at the opposite end.
SG350-52MP-K9-UK provides a 740W PoE budget where SG350-52P-K9-UK provides 375W. Both models are discontinued, so this comparison concerns legacy replacement requirements rather than a current-generation purchase. The Max-PoE model matches larger combined endpoint allocations; the lower-budget model corresponds to installations whose powered devices require less shared capacity.
SG350-52MP-K9-UK has 48 dedicated Gigabit access ports, while SG350-28MP-K9-UK has 24. Both models are discontinued, and the comparison is primarily about matching existing endpoint density. The larger model fits legacy replacement port lists exceeding 24 access connections; the smaller model corresponds to lower-density installations.
C1300-48FP-4G provides four dedicated 1G SFP uplinks, whereas SG350-52MP-K9-UK combines two dedicated SFP uplinks with two copper/SFP combo connections. C1300-48FP-4G is the current endpoint of the replacement chain. The SG350 model serves legacy continuity; the Catalyst model suits buyers moving to the current migration option with dedicated fiber uplinks.
Yes, Cisco 350 Series switches support LACP with eight aggregation groups and eight active ports per group. Dynamic groups can have 16 candidate ports each. Configure compatible aggregation settings at both ends and account for the physical interfaces assigned to each group before specifying the required network connections.
