SG300-52P-K9-UK is a managed Layer 2+ access switch with 48 Gigabit PoE+ ports, two additional Gigabit copper ports, and two Gigabit copper/SFP combo connections. Fixed uplinks keep the connection layout independent of removable network cards, while the 1U rack-mount chassis fits a standard equipment rack. The Cisco 300 Series serves SMB networks combining data connections with powered endpoints. Native 10/100/1000 interfaces accommodate existing copper patching, and the SFP connections provide a fiber uplink option. The discontinued SG300-52MP increases the PoE budget to 740W; that distinction matters when matching the power allocation of an installed legacy unit rather than assuming every 52-port model carries the same endpoint-power capacity.

104 Gbps switching capacity supports traffic across the access and uplink connections, while 77.38 Mpps forwarding performance describes handling of minimum-size packets. 375W of shared PoE capacity sets the aggregate endpoint-power ceiling independently of available socket count. Static IPv4 routing supports manually maintained inter-VLAN paths, with 512 static routes and 128 IP interfaces defining the routing configuration limits. The Small Business 300 family accommodates 4000 active VLANs for traffic segmentation and a 16000-entry MAC address table for endpoint learning. SG300-52P-K9-UK reaches 473.62W worst-case consumption at 110V AC, so upstream circuit and backup-power sizing must include the powered-endpoint load rather than chassis consumption alone. Four fans provide active cooling, and the 0°C to 45°C operating range sets the ambient-temperature boundary for installation. Universal 100-240V AC input accommodates different supply voltages without requiring an external power adapter.
ORM Systems offers SG300-52P-K9-UK new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year of ORM warranty; every condition includes 30-day returns, terms apply. Certified 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. Cisco service has ended, so specify the required ORM condition and coverage on the order rather than relying on the original Cisco warranty. Submit the purchase order with quantities and required accessories; PO accepted, Net-30 for government, and RMA with advance replacement support enterprise and volume purchasing.

When an existing installation needs additional powered endpoints, the 30W per-port ceiling must be considered separately from aggregate power allocation. Prepare an endpoint schedule showing each device's requested power and any planned additions. Specify the required simultaneous load before placing the purchase order.
When a staging team prepares equipment for administrators working in different languages, the Cisco 300 Series offers seven interface languages. Keep the selected language consistent with the receiving team's operating procedures and configuration records. Specify the interface language and acceptance checklist before the order enters staging.
When a spare must match an installed SG300-52P-K9-UK, retain the complete ordering identity rather than substituting a shortened hardware name. ORM provides regional stock and RMA handling across the UK, EU, US and MEA. Specify the required condition, quantity and RMA region on the purchase order.
30W on every powered port
SG300-52P-K9-UK shares 375W across 48 powered ports; 48 × 30W = 1440W exceeds that budget. A simultaneous full-power endpoint requirement cannot be met.
10G fiber uplinks
SG300-52P-K9-UK has Gigabit uplink connections rather than 10G SFP+ uplinks. C1300-48P-4X provides 48 Gigabit PoE access ports with four 10G SFP+ uplinks.
Active Cisco service coverage
Cisco service has ended for the Small Business 300 family. C1300-48P-4G is the migration-chain endpoint for buyers requiring a replacement rather than discontinued legacy hardware.

SG300-52P-K9-UK identifies a Cisco 300-family 52-port Gigabit PoE managed switch. SG300 identifies the Gigabit managed family, 52 denotes the total connection count, and P identifies the powered model. Retain the complete K9-UK portion when matching the quotation and purchase order to the required ordering identity.
The Small Business 300 series supports browser-based configuration, a local serial console, command-line access over SSH or Telnet, and SNMP management. These are configurable managed switches rather than unmanaged devices. Specify the intended administration method and access credentials during staging so the receiving team can establish its management workflow.
SG300-52P-K9-UK provides a shared 375W PoE budget across 48 powered ports, with a maximum of 30W on an individual powered port. The aggregate budget does not support every port drawing its individual maximum simultaneously. Size the installation from endpoint power allocations rather than powered-port count alone.
SG300-52P-K9-UK has two additional Gigabit copper connections and two Gigabit copper/SFP combo connections beyond its 48 powered access ports. The uplink architecture is fixed rather than based on a removable network card. Match the selected copper or fiber connection type to the required link before ordering associated cabling.
Yes, SG300-52P-K9-UK supports static IPv4 routing between VLANs, with 512 static routes and 128 IP interfaces. Its routing configuration uses manually maintained paths. Confirm that the planned interface count and static routing entries fit those limits before using the switch as the gateway for multiple network segments.
SG300-52P-K9-UK is discontinued, and Cisco support ended November 30, 2023. SG350-52P-K9-UK was the immediate replacement but is also discontinued. The migration chain continues through discontinued CBS350-48P-4G-UK to C1300-48P-4G, so a legacy replacement purchase and a new-generation replacement purchase require different ordering decisions.
ORM Systems offers SG300-52P-K9-UK new sealed with up to a 3-year extended warranty, or certified refurbished with up to 1 year of ORM warranty. Both conditions have 30-day returns, terms apply. Cisco's original limited lifetime warranty is no longer active because Cisco service ended November 30, 2023.
SG300-52P-K9-UK occupies 1U and measures 440 mm wide, 350 mm deep and 44.45 mm high, with a weight of 5.3 kg. Its operating temperature range is 0°C to 45°C. Allow installation clearance beyond the chassis dimensions for connected cables and unobstructed ventilation.
SG300-52P-K9-UK has a 375W PoE budget, while SG300-52MP increases that budget to 740W across the same number of powered ports. Both models are discontinued. The former suits matching an existing lower-budget installation; the latter suits maintaining an existing installation that requires the higher aggregate endpoint-power allocation.
SG300-52P-K9-UK provides 48 powered access ports, whereas SG300-28MP provides 24 powered access ports; both have a 375W PoE budget. Both models are discontinued. The larger model suits higher-density legacy port requirements, while the smaller model suits matching an existing installation with fewer powered endpoint connections.
SG300-52P-K9-UK combines two additional copper connections with two copper/SFP combo connections, while C1300-48P-4G provides four dedicated Gigabit SFP uplinks. The discontinued model suits exact legacy hardware matching. C1300-48P-4G suits a migration purchase that retains 48 Gigabit PoE access ports but changes the uplink connection layout.
SG300-52P-K9-UK reaches 473.62W worst-case consumption at 110V AC, including PoE operation; the corresponding 220V figure is 461.88W. These figures describe input consumption rather than the 375W endpoint-power budget. Use the appropriate supply-voltage figure when sizing upstream electrical circuits and backup-power capacity for the installation.
