SG300-10SFP-K9 is a fanless desktop managed switch with eight dedicated Gigabit SFP ports and two fixed Gigabit copper/SFP combo uplinks. Static IPv4 routing places its capabilities in Layer 2+, while its non-PoE configuration carries data without supplying endpoint power. The Cisco 300 Series serves small-business networks requiring managed switching and fiber connections rather than a bank of copper access ports. Each combo connection uses either its copper interface or its SFP interface, not both simultaneously. The discontinued SRW2008-K9 differs by providing eight dedicated copper access ports instead of eight dedicated SFP ports. For an existing fiber installation, the SG300-10SFP configuration preserves the distinction between dedicated optical connections and shared-media uplinks when preparing the port assignment and purchase order.

20 Gbps switching capacity provides the switching fabric for the available connections. 14.88 Mpps forwarding performance applies to 64-byte packets, keeping the packet-rate specification distinct from aggregate bandwidth. Static IPv4 routing supports 512 routes for manually configured forwarding between networks; automatic route exchange is not part of that routing capability. SG300-10SFP-K9 carries 128 MB of memory and 16 MB of flash for its operating software and configuration storage. A dynamically shared 8 Mb packet buffer serves the ports collectively rather than reserving that amount for each connection. The MAC address table accommodates 16000 entries for learned forwarding destinations. STP, RSTP and MSTP provide spanning-tree controls, while LACP supports link aggregation. Browser-based configuration provides a management path, and SSH supplies encrypted remote access in place of Telnet. These controls require deliberate configuration of network segmentation, aggregation and administrative access before the unit enters service.
SG300-10SFP-K9 is offered new sealed or certified refurbished; new units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and every condition has 30-day returns, with terms applying. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, optics bay recognition and supplied-adapter output, with firmware verified and configuration wiped to factory default. Specify the condition, optics, supplied adapter and quantity on the purchase order. PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA across the UK, EU, US and MEA support enterprise and volume orders.

An existing small-business network needing local forwarding between separately addressed segments can use the switch's capacity for 128 IP interfaces. Prepare the interface addressing and next-hop plan before ordering, and confirm which connections must participate in routed operation rather than simply carrying tagged traffic between adjacent devices.
A staging lab testing storage or other large-frame traffic can use support for 9216-byte jumbo frames. Treat frame size as an end-to-end requirement rather than a switch-only setting: identify the connected devices and intermediate links, then specify the intended frame-size configuration in the staging instructions before the PO.
A branch rollout carrying multicast traffic can use IGMP snooping with support for 1000 multicast groups. Establish the expected group count and identify the multicast querier before equipment is ordered. Include the required multicast configuration and acceptance checks in the deployment instructions rather than assuming ordinary unicast testing covers that traffic.
10G uplinks to distribution
SG300-10SFP-K9 has Gigabit uplinks, not 10G SFP+ uplinks. A purchase requiring a 10G distribution connection needs a different switch; installing an optic does not increase the uplink speed.
Switch-powered phones or access points
SG300-10SFP-K9 does not supply PoE through its copper connections. Phones or access points requiring power from the switch need a powered switching configuration or a separate endpoint power arrangement.
Ongoing Cisco service entitlement
Cisco service for the 300 Series has ended. Its replacement line also ends with a discontinued model without a current migration product, so this is a legacy-stock purchase.

SG300-10SFP-K9 identifies a Cisco 300 Series Gigabit managed SFP switch with ten logical connections. The 10 designation corresponds to eight dedicated SFP ports and two combo connections; SFP identifies the fiber-oriented configuration. Specify the complete PID to distinguish this model from the series' copper-port configurations.
SG300-10SFP-K9 supports browser-based configuration and command-line management, with HTTPS for encrypted browser access and SSH as the encrypted alternative to Telnet. The web interface manages the switch's settings rather than merely displaying status. Specify the intended administrative access method and credentials before putting a refurbished unit into service.
SG300-10SFP-K9 is discontinued, and Cisco service for the 300 Series has ended. The replacement line passes through the discontinued SG350-10SFP-K9-NA to the discontinued CBS350-8S-E-2G-NA, which has no current migration product. Treat an order as procurement of legacy hardware rather than a currently supported Cisco product.
ORM Systems offers SG300-10SFP-K9 new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Returns are available for 30 days in every condition; terms apply. Cisco's original Limited Lifetime hardware warranty has ended with Cisco service.
No, SG300-10SFP-K9 does not provide PoE power to connected devices. The two copper interfaces belong to shared copper/SFP combo connections and carry data without endpoint power delivery. Account for the power arrangement of every attached phone, access point or other powered device separately when preparing the purchase order.
The Cisco 300 Series supports MGBSX1 for Gigabit multimode fiber and MGBLX1 for Gigabit single-mode fiber. MGBSX1 reaches 300 m, while MGBLX1 reaches 10 km. Select the optic PID according to the installed fiber and link length, and match the connection requirements at the other end.
Yes, SG300-10SFP-K9 supports static IPv4 routing with capacity for 512 routes and 128 IP interfaces. Routed operation uses manually configured forwarding rather than automatic route exchange. Prepare the interface addresses and next-hop relationships before deployment, and distinguish the required routed configuration from ordinary VLAN-aware bridging.
The SG300-10SFP has a desktop chassis measuring 279.4 mm wide, 44.45 mm high and 170 mm deep, with a weight of 2.125 kg. Its operating temperature range is 0°C to 45°C. Confirm the installation space, cable access and environmental conditions before specifying the unit for a cabinet.
SRW2008P-K9 supplies PoE through eight copper access ports with a shared 62W budget, whereas SG300-10SFP-K9 is non-PoE and fiber-oriented. Both are discontinued configurations. The former addresses legacy powered-copper connections; the latter addresses legacy SFP connections where endpoint power delivery from the switch is not required.
SG300-28SFP-K9 uses an internal AC power supply, while SG300-10SFP-K9 uses an external AC adapter. Both models are discontinued. The larger configuration suits legacy installations requiring its internal-power arrangement; the smaller configuration suits installations specifying the external adapter, which should be included explicitly in the order requirements.
SG300-10SFP-K9 has eight dedicated SFP connections, while SRW2008-K9 has eight dedicated copper Gigabit connections. Both retain two combo connections and are discontinued. Choose the SFP configuration for legacy optical cabling; choose the copper configuration when preserving an existing copper-port installation is the purchasing requirement.
SG300-10SFP-K9's North American replacement line begins with SG350-10SFP-K9-NA, discontinued on July 30, 2022, and continues to CBS350-8S-E-2G-NA, discontinued on May 30, 2024. The latter has no current migration product. Neither model should be treated as an active-product successor when preparing a replacement purchase.
The Cisco 300 Series supports STP, RSTP, MSTP and LACP for spanning-tree control and link aggregation. LACP supports eight groups with eight active ports per group, subject to the connections available on the model. Specify the aggregation members and spanning-tree configuration rather than assuming those features operate without configuration.
