SG300-52P-K9-EU is a managed Layer 2+ switch with 48 Gigabit PoE+ access ports in a full-width 1U chassis. Its fixed uplinks provide two dedicated Gigabit copper connections and two Gigabit combo connections, allowing copper or fiber connectivity without an uplink card. Each combo connection uses its copper interface or SFP interface, not both simultaneously. The Small Business 300 family serves office networks carrying data, voice, wireless and security traffic. The discontinued SG300-52MP-K9 increases the endpoint-power budget to 740W without increasing access-port density, distinguishing higher-power legacy installations from those using this model's smaller shared allocation.

104 Gbps switching capacity supports wire-speed switching across the available interfaces. 77.38 Mpps forwarding handles minimum-size packets, keeping the packet-rate figure distinct from aggregate bandwidth. 375W of shared PoE power requires endpoint allocation rather than assuming maximum output on every powered port simultaneously. Static IPv4 routing supports 512 routes for networks using manually defined paths between VLANs; dynamic routing is not provided. SG300-52P-K9-EU combines 128 MB of memory with 16 MB of flash for its embedded software and configuration. The Cisco 300 Series supports 16384 MAC addresses, giving buyers a defined address-learning ceiling when assessing an existing network configuration.
SG300-52P-K9-EU is offered new sealed or certified refurbished; specify condition, quantity and required accessories on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, PoE output under load on every powered port and optics bay recognition; firmware is verified and configurations are wiped to factory default. ORM provides up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units and 30-day returns on every condition, terms apply; Cisco's original limited lifetime hardware warranty ended October 31, 2023. Enterprise and volume orders accept POs, government Net-30 and RMA with advance replacement, with regional stock and RMA across UK, EU, US and MEA.

When separate office VLANs need local communication, the switch supports 128 IP interfaces alongside DHCP server and relay functions. Map the required interfaces, address pools and upstream return paths before procurement, then specify the configuration work required for the intended VLAN layout rather than treating installation as cable replacement.
When multiple locations need the same configuration baseline, text-editable configuration files and SCP file transfer support a repeatable staging workflow. Separate site-specific addressing from common settings, prepare the approved configuration files, and specify staging requirements on the purchase order before allocating units to individual locations.
Active Cisco hardware support
Cisco service ended on October 31, 2023. C1300-48P-4G is the current migration endpoint, with 48 Gigabit access ports and four dedicated Gigabit SFP uplinks.
10G uplinks to distribution
SG300-52P-K9-EU provides Gigabit uplinks only. Neither its dedicated copper connections nor its shared SFP connections provides 10G connectivity, and no uplink-card bay is available.

SG300-52P-K9-EU identifies a Cisco Small Business 300 managed Gigabit PoE+ switch with 52 logical network connections. Its configuration comprises 48 powered access ports, two additional copper ports and two copper/SFP combo connections. Keep the complete PID on the purchase order rather than substituting the shorter model name.
SG300-52P-K9-EU supports a browser-based interface and Textview CLI, with console access and SSH or Telnet for command-line sessions. Legacy integration options include Cisco FindIT discovery and Cisco OnPlus. Specify the intended local management method and configuration-staging requirements when preparing replacement units for an existing installation.
SG300-52P-K9-EU is discontinued: sales ended October 4, 2018, and Cisco service ended October 31, 2023. Its migration chain passes through discontinued SG350-52P-K9-EU and discontinued CBS350-48P-4G-EU to C1300-48P-4G. Purchasing a new sealed unit does not restart the expired Cisco support period.
ORM offers SG300-52P-K9-EU 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. Every condition has 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco service on October 31, 2023.
SG300-52P-K9-EU provides a shared 375W budget across 48 PoE+ ports, with a maximum of 30W on an individual powered port. The shared ceiling prevents all powered ports from supplying their individual maximum simultaneously. Size the order against simultaneous endpoint demand rather than multiplying connected devices by port availability alone.
SG300-52P-K9-EU provides two dedicated Gigabit copper uplinks and two Gigabit copper/SFP combo connections. Each combo connection operates through copper or fiber, not both simultaneously. Fiber orders can specify MGBSX1 for multimode links or MGBLX1 for single-mode links, with the media and distance checked before the purchase order.
Yes, SG300-52P-K9-EU supports static IPv4 routing between VLANs, with 512 static routes and 128 IP interfaces. Routing paths require explicit configuration rather than dynamic route exchange. Include the VLAN interfaces, upstream next hops and return routes in the configuration scope before specifying a replacement for a routed installation.
SG300-52P-K9-EU has a 375W PoE budget, while SG300-52MP-K9 provides 740W across the same 48 powered access ports. Both belong to the discontinued Small Business 300 family. The former matches lower aggregate endpoint-power requirements; the latter matches legacy installations requiring a larger shared power allocation without additional access ports.
SG300-52P-K9-EU provides 48 powered access ports, while SG300-28MP-K9 provides 24; both have a 375W PoE budget. Both models are discontinued. The larger model suits legacy replacements requiring greater connection density, while the smaller model matches installations needing fewer powered connections within the same aggregate endpoint-power ceiling.
C1300-48P-4G provides four dedicated Gigabit SFP uplinks, whereas SG300-52P-K9-EU combines two dedicated copper uplinks with two copper/SFP combo connections. C1300-48P-4G is the current migration endpoint. The older model matches existing hardware requirements; the successor suits new purchases requiring dedicated fiber uplink connections rather than shared copper/fiber interfaces.
