SG300-28MP-K9-EU provides managed Gigabit connectivity with 24 PoE+ access ports, two additional Gigabit copper connections and two Gigabit copper/SFP combo connections. Each combo connection uses either its copper interface or its SFP interface, not both simultaneously. The fixed uplink architecture has no removable uplink card. The Cisco 300 Series serves small-business networks connecting computers, IP phones, wireless access points and cameras. Static IPv4 routing places this model in the Layer 2+ category. Compared with the discontinued SG300-28PP-K9-EU and its 180W allocation, this Max-PoE model provides a larger shared endpoint-power budget without changing the Gigabit connection class.

56 Gbps switching capacity supports traffic across the fixed interfaces, while 41.67 Mpps forwarding performance specifies processing throughput for 64-byte packets. 375W of shared PoE capacity supplies powered devices according to their combined allocation rather than guaranteeing maximum output on every powered port simultaneously. 445W worst-case input consumption at 110V provides the electrical-planning figure when PoE loading is included; the corresponding 220V figure is 436W. SG300-28MP-K9-EU supports a 16384-entry MAC address table for learned Ethernet destinations. Static IPv4 routing provides manually configured paths between subnets rather than automatic route exchange. Administrators configure the SG300-28MP through its web interface or CLI, with serial-console access and SSH support. Hardware stacking is not available, so additional switches remain separately configured devices rather than members of a shared switching chassis.
SG300-28MP-K9-EU is offered new sealed or certified refurbished, with ORM warranty coverage of up to a 3-year extended warranty for new hardware and up to 1 year for certified refurbished hardware; returns are available for 30 days on every condition, with terms applying. 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. Specify the required condition, complete regional PID and quantity on the purchase order. ORM accepts POs and provides Net-30 for government, with RMA advance replacement and regional stock/RMA coverage across the UK, EU, US and MEA for enterprise and volume orders.

When a phone, camera or wireless access point refresh changes endpoint demand, size the powered-device list before selecting a switch quantity. Each powered port can supply 30W, but simultaneous allocations remain subject to a shared ceiling. Specify endpoint maximum draw and power priority before the PO.
When a branch unit must be configured before shipment, plan a local staging session rather than assuming the production network will provide first access. The management connection includes a DB-9 serial console, separate from user traffic. Include console access and the intended configuration handoff in the order requirements.
10G connections to upstream equipment
SG300-28MP-K9-EU offers fixed Gigabit interfaces only. Installing different optics cannot enable 10G operation, and no removable uplink card can add faster connections.
Maximum power across every powered port
The 375W shared allocation does not cover 24 ports drawing 30W simultaneously. Size the purchase against aggregate endpoint demand rather than the individual port maximum.
An active Cisco hardware service entitlement
SG300-28MP-K9-EU has reached retirement and Cisco service has ended. The migration chain leads to C1300-24FP-4G, which changes the uplinks to four dedicated Gigabit SFP connections.

SG300-28MP-K9-EU identifies the Cisco Small Business 300 Gigabit Max-PoE managed switch with 28 logical network connections. The 28 includes the additional copper and combo connections, while MP identifies Max-PoE. Retain the complete K9-EU ordering identifier on the PO to distinguish this form from the separately listed NA and UK forms.
SG300-28MP-K9-EU provides 24 Gigabit PoE+ access ports, two additional Gigabit copper ports and two Gigabit copper/SFP combo connections. A combo connection activates either copper or fiber, not both together. The SFP cages are fixed interfaces, so inserting an optical transceiver does not add another logical network connection.
SG300-28MP-K9-EU provides a shared 375W PoE budget across 24 powered ports, with a maximum of 30W on an individual PoE+ port. The total allocation remains the limiting factor when several devices request higher power. Check the combined endpoint requirement rather than assuming every powered port can deliver 30W simultaneously.
The Cisco Small Business 300 provides a web-based configuration interface and CLI management; SG300-28MP also includes a DB-9 serial console and SSH support. The console provides a local access path for staging. Establish administrative credentials and confirm the intended management connection before handing a configured unit to another site.
Yes, SG300-28MP-K9-EU supports static IPv4 routing between subnets. Routes are configured manually rather than learned through automatic route exchange, which places this configuration in the Layer 2+ category. A network requiring dynamic routing should keep that function on a separate routing device rather than treating static routes as equivalent capability.
No, the SG300-28MP is a standalone managed switch rather than a hardware-stack member. Connecting additional switches through Ethernet does not merge their configuration or create a shared switching chassis. Plan administration for each unit separately, and do not include stacking hardware on the purchase order for this model.
SG300-28MP-K9-EU has worst-case consumption of 445W at 110V or 436W at 220V when PoE loading is included. These input figures are different from the power available to endpoints. Use total consumption for electrical planning, and use the separate PoE allocation when checking the attached powered-device load.
Yes, SG300-28MP-K9-EU is discontinued, and Cisco service for the retired Small Business 300 family has ended. End of sale was August 2, 2018. The replacement path passes through the discontinued SG350-28MP-K9-EU and CBS350-24FP-4G-EU before reaching C1300-24FP-4G; those intermediate products should not be mistaken for the final migration target.
SG300-28MP-K9-EU provides a 375W shared PoE allocation, while SG300-28PP-K9-EU provides 180W; both have 24 powered access ports supporting PoE+. Both models are discontinued. The MP model addresses a larger aggregate endpoint-power requirement, while the PP model fits an existing lower-power configuration that remains within its smaller allocation.
SG300-28MP-K9-EU has 24 powered Gigabit access ports, while SG300-52P-K9 has 48 powered Gigabit access ports. Both carry a shared 375W PoE allocation and belong to the retired 300 family. The smaller model fits fewer endpoint connections; the larger model addresses greater connection density without increasing the total PoE allocation.
SG300-28MP-K9-EU provides two dedicated Gigabit copper connections and two Gigabit copper/SFP combo connections, whereas C1300-24FP-4G provides four dedicated Gigabit SFP uplinks. C1300-24FP-4G is the migration target after the discontinued intermediate models. The older arrangement fits an existing mixed copper/fiber connection plan; the newer arrangement suits four separate fiber uplinks.
New sealed and certified refurbished SG300-28MP-K9-EU units carry ORM warranties: new hardware has up to a 3-year extended warranty, and certified refurbished hardware has up to 1 year. Returns are available for 30 days on every condition; terms apply. Cisco's original Limited Lifetime Hardware Warranty coverage has ended.
