SF300-24P-K9 is a Cisco 300 Series managed Fast Ethernet switch with 24 10/100 Mbps access ports that supply standard PoE power to connected devices. Two dedicated Gigabit copper uplinks and two Gigabit copper/SFP combo connections provide a choice of electrical or fiber connections at the network edge. The 180W shared PoE allocation is important when multiple cameras, phones or wireless access points draw power simultaneously. Designed for small-business access networks, this rack-width switch combines conventional Ethernet access with configurable VLAN and routing functions. The Cisco SF300-24P is distinct from the non-PoE SF300-24, which requires separately powered endpoint equipment. A 24-port deployment also needs to account for the Gigabit uplink connection layout because the combo copper and optical interfaces represent alternative media for the same logical connections. The chassis has a fixed port configuration rather than an expansion-module system.

12.8 Gbps switching capacity provides the internal bandwidth for the installed Fast Ethernet access and Gigabit uplink interfaces. 9.52 Mpps forwarding performance describes the packet-handling rate for 64-byte frames. The 180W PoE budget is shared among 24 powered ports, so a full population of devices rated at 15.4W each exceeds the supply allocation. 16,000 MAC addresses permit a substantial learned endpoint table for a switch in this small-business class. The Cisco SF300-24P-K9 supports managed switching, VLAN segmentation and static IP routing, with an embedded management interface for local administration. IPv4 routing can be used between configured VLAN interfaces without assuming dynamic routing protocols that belong to larger enterprise platforms. The two combo connections accept either the electrical Gigabit interface or the corresponding SFP optical interface rather than both simultaneously. No dedicated hardware stacking connectors or removable uplink modules are provided. Power is supplied through the chassis AC input, with powered endpoint capacity dependent on the overall shared allocation.
SF300-24P-K9 is offered by ORM Systems in new sealed and certified refurbished condition. Certified refurbished managed units are inspected and bench-tested for power-on, POST, clean boot, port links at rated speeds and PoE delivery under load, with firmware verified and configuration reset to factory defaults. Confirm the required number of powered endpoints, Gigabit uplink media and matching regional stock before issuing the purchase order. New units carry up to a 3-year extended ORM warranty, while certified refurbished units carry up to 1 year; returns are available within 30 days on either condition, subject to terms. ORM accepts purchase orders, offers Net-30 to government buyers and provides RMA with advance replacement, supported by regional stock and RMA coverage in the UK, EU, US and MEA.

When an existing small-business installation already uses 10/100 Mbps endpoint links and standard PoE, a replacement switch must preserve 24 powered ports without requiring new powered-device adapters. The SF300-24P family provides a shared 180W allocation. Before the PO, total the connected endpoints’ maximum wattage and verify that the existing cabling remains suitable.
A wiring closet that connects to both nearby copper distribution equipment and a fiber handoff must account for the switch’s two Gigabit copper uplinks and two shared copper/SFP combo interfaces. Each combo position uses one medium at a time. Specify compatible SFP optics, patch leads and the required active interface allocation before ordering.
A branch maintaining older 300 Series switching can require a spare with matching 24-port Fast Ethernet connectivity and standard PoE behavior rather than a redesigned access layer. Refurbished managed units undergo firmware verification and factory-default configuration wiping. Record the deployed firmware, management settings and 180W power requirement before adding the spare to a purchase order.
Gigabit speed on every endpoint
The 24 access ports operate at 10/100 Mbps rather than Gigabit Ethernet. A current Gigabit access switch is required if every wired endpoint needs 1GbE.
Full PoE load on all ports
The shared 180W supply cannot provide 15.4W simultaneously to all 24 powered ports. Specify a current higher-budget PoE platform for that requirement.
Dedicated switch stacking hardware
The SF300-24P has no dedicated physical stacking connectors. A platform with supported hardware stacking is required when one stack control plane is mandatory.

SF300-24P-K9 identifies the Cisco SF300-24P, a 24-port 10/100 Mbps managed switch with standard PoE and Gigabit uplinks. The SF300-24P model is the PoE member of the Cisco 300 Series. Its 24 powered access ports and shared 180W allocation distinguish the hardware from the non-PoE model.
Cisco SF300-24P-K9 is managed through the switch’s embedded web administration interface and command-line management facilities. Administrators can configure switching functions, VLANs and IP settings rather than operating the hardware as an unmanaged switch. A refurbished unit is firmware verified and returned to factory defaults before it is supplied.
Cisco SF300-24P-K9 belongs to the retired Cisco 300 Series managed switch family. Cisco no longer provides support for the retired family. Buyers maintaining deployed networks should distinguish availability of third-party or reseller inventory from ongoing manufacturer support and plan for the consequences of operating a retired device.
Cisco SF300-24P-K9 is available from ORM Systems as new sealed or certified refurbished equipment. Cisco manufacturer support has ended for the retired 300 Series. 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 subject to terms.
Cisco SF300-24P-K9 provides a total shared PoE budget of 180W across 24 Fast Ethernet access ports. Standard PoE endpoints can consume different amounts of power, so the budget does not guarantee the maximum permitted power on every port at once. Add the expected endpoint loads before selecting this chassis.
Cisco SF300-24P-K9 includes two dedicated 10/100/1000 Mbps RJ-45 uplinks and two Gigabit copper/SFP combo connections. Each combo position supports copper or optical media, not both active together. Optical links require compatible SFP transceivers and appropriate cabling, which should be specified separately on the purchase order.
Cisco SF300-24P-K9 does not provide dedicated hardware stacking ports or a hardware stack-backplane connection. It is managed as an individual switch rather than joined into a single switch fabric through a dedicated stacking kit. Buyers requiring physical stack operation need a platform expressly built for that capability.
Cisco SF300-24P-K9 has 24 Fast Ethernet access ports operating at 10/100 Mbps, not 1000 Mbps. Its Gigabit capability is used for uplink connections: two copper ports plus two combo copper/SFP positions. A design requiring Gigabit speed on every user port must use different access hardware.
Cisco SF300-24P-K9 uses the embedded Cisco 300 Series management feature set rather than a Catalyst 9000-style network subscription tier. Its existing features are configured on the switch itself. There is no Network Essentials or Network Advantage suffix in the supplied PID, so those enterprise licensing tiers should not be applied.
Cisco SF300-24P-K9 has 12.8 Gbps switching capacity and a published forwarding rate of 9.52 million packets per second for 64-byte packets. These values describe separate aspects of forwarding performance. They should not be confused with endpoint link rates, which remain 10/100 Mbps on the 24 access ports.
Cisco SF300-24P-K9 supports static IP routing in addition to managed Layer 2 switching functions. Static routing requires administrators to define the routes used between the configured networks. Deployments needing a dynamic routing control plane should not assume enterprise routing protocols are present in this small-business product.
