SG300-10SFP-K9-EU is a fanless, managed Layer 2+ desktop switch for fiber-led small-business networks. Eight dedicated Gigabit SFP ports handle optical connections, while two fixed Gigabit combo interfaces let each remaining connection use copper or fiber. The Cisco Small Business 300 configuration provides data connectivity without supplying endpoint power, separating fiber aggregation from powered copper access. The discontinued SRW2008P-K9 differs by providing eight copper PoE ports. Cisco 300 Series switches combine configurable traffic separation and access controls for networks requiring more administration than unmanaged switching. The fixed-interface arrangement keeps equipment selection focused on link media, optical compatibility, and termination requirements rather than removable network-module selection.

20 Gbps switching capacity supports the fixed interface configuration, while 14.88 Mpps forwarding performance describes processing at a 64-byte packet size. Static IPv4 routing carries traffic between configured networks without requiring every local connection to traverse an external router. STP/RSTP/MSTP provide spanning-tree options, and UDLD detects one-way connections caused by wiring or interface faults. A 9216-byte jumbo-frame ceiling permits larger Ethernet frames when the connected devices share compatible settings. SG300-10SFP-K9-EU supports browser-based administration protected by HTTPS and secure remote administration through SSH. RADIUS authentication and time-based 802.1X controls provide endpoint authorization independently of whether a physical link is established. 18.1W worst-case consumption at 110V supplies the system-load figure for electrical planning; the corresponding figure at 220V is 17.71W. The hardware has no 10G SFP+ uplinks or removable port-expansion cards, so interface speed cannot be increased through an uplink-module purchase.
ORM Systems supplies SG300-10SFP-K9-EU new sealed or certified refurbished; refurbished units are inspected and bench-tested, with optics bay recognition, firmware verification, and configuration wiped to factory default. Specify the condition and required accessories on the PO; new units carry up to a 3-year extended warranty, certified refurbished units up to 1 year, and every condition includes 30-day returns, terms apply. Cisco's original limited lifetime hardware warranty ended with service on October 31, 2023. For enterprise and volume requirements, POs are accepted, government orders qualify for Net-30, and RMA with advance replacement is available, with regional stock/RMA across the UK, EU, US, and MEA.

When existing multimode runs terminate at 100 Mbps, replacement selection starts with optical speed rather than the SFP cage shape. MFEFX1 supports 100 Mbps over multimode fiber to 2 km on this switch. Match both ends of each connection and specify MFEFX1 quantities before the purchase order.
When a branch needs communication between VLANs, the switch supports 128 IP interfaces across physical ports, link aggregation groups, VLAN interfaces, and loopbacks. Map the required interfaces and DHCP relay boundaries during staging rather than treating every connection as an unconfigured bridge. Specify the required interface configuration with the order.
When a staging environment must reproduce bundled Ethernet connections, the switch supports eight LACP groups with eight ports per group. Available physical interfaces still constrain the configuration on this chassis. Build the intended group membership map and confirm the peer settings before specifying the unit for the lab order.
10G fiber uplinks
SG300-10SFP-K9-EU limits its fixed fiber interfaces to 1GbE and has no SFP+ uplinks. A deployment requiring 10G distribution connections needs different hardware.
PoE-powered phones or access points
SG300-10SFP-K9-EU supplies no PoE through its copper combo interfaces. Powered endpoints require separate power or a different switch with powered RJ-45 access ports.

SG300-10SFP-K9-EU identifies a Cisco Small Business 300 managed Gigabit SFP switch with ten usable interfaces: eight dedicated SFP connections and two copper-or-fiber combo connections. The 300 designation identifies the series, 10 describes total interfaces, and SFP distinguishes the fiber-focused configuration. Retain the complete ordering code when matching inventory.
SG300-10SFP-K9-EU supports a web interface over HTTP or HTTPS, CLI administration through the console or SSH/Telnet, and SNMP v1, v2c, or v3. RMON monitoring is also supported. Use HTTPS and SSH for encrypted remote administration, and align monitoring access with the site's security requirements before deployment.
SG300-10SFP-K9-EU is discontinued: end of sale was October 4, 2018, and Cisco service ended October 31, 2023. An existing unit can continue operating, but purchasing another unit does not restart manufacturer support. Separate operational continuity planning from any expectation of renewed Cisco maintenance or service eligibility.
ORM Systems offers SG300-10SFP-K9-EU new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are 30 days for every condition; terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco service on October 31, 2023.
SG300-10SFP-K9-EU has no PoE, whereas the discontinued SRW2008P-K9 supplies eight copper PoE ports from a shared 62W budget. The former corresponds to existing optical connections; the latter corresponds to legacy installations requiring copper cabling and endpoint power. Both configurations also provide two copper-or-fiber combo interfaces.
SG300-10SFP-K9-EU provides eight dedicated SFP ports, while the discontinued SRW2008-K9 provides eight dedicated copper Gigabit ports. Both add two combo interfaces shared between copper and fiber. Existing optical terminations distinguish the SFP model, while directly connected copper endpoints distinguish the SRW2008-K9 configuration for legacy equipment matching.
SG300-10SFP-K9-EU has eight dedicated SFP ports, whereas the discontinued SG300-28SFP-K9 has 26 dedicated SFP ports; both add two combo interfaces. The smaller configuration corresponds to a limited fiber termination count. The larger configuration corresponds to legacy installations that already require substantially more optical connections within one chassis.
SG300-10SFP-K9-EU supports ten simultaneous connections, not twelve, because each of its two combo interfaces shares one copper connection with one SFP connection. Eight SFP interfaces remain dedicated to fiber. Select copper or fiber on each combo interface when preparing the connection schedule and checking the required transceiver quantities.
Cisco Small Business 300 supports MGBSX1 for Gigabit multimode fiber and MGBLX1 for Gigabit single-mode fiber. MGBSX1 supports 300 m, while MGBLX1 supports 10 km. Match fiber type, distance, and the remote transceiver before specifying quantities; the supported optics do not convert these interfaces into 10G connections.
Yes, SG300-10SFP-K9-EU supports static IPv4 routing with 512 static routes and 128 IP interfaces. Routed interfaces can use physical ports, link aggregation groups, VLANs, or loopbacks. Plan the routes explicitly and retain a separate routing device wherever the network depends on dynamic route exchange rather than configured static paths.
SG300-10SFP-K9-EU uses an external AC adapter accepting 100-240V AC at 50-60 Hz. Worst-case consumption is 18.1W at 110V or 17.71W at 220V. Specify the required power accessories and destination electrical supply with the order; copper combo connections carry data and do not replace the external power input.
The Cisco Small Business 300 desktop fiber configuration is 279.4 mm wide, 44.45 mm high, and 170 mm deep, with a weight of 2.125 kg. Allow space for the external adapter and fiber routing when planning placement, and confirm mounting hardware with the order instead of assuming a full-width chassis.
No, SG300-10SFP-K9-EU provides fixed Gigabit Ethernet fiber and combo interfaces rather than 10G SFP+ uplinks. No removable uplink card raises the individual connection speed. Link aggregation can combine eligible connections, but it does not create a 10G physical interface or change the speed of an individual port.
SG350-10SFP-K9-EU, now discontinued, replaced SG300-10SFP-K9-EU. The next replacement, CBS350-8S-E-2G-EU, is also discontinued and has no current migration product. This chain therefore provides no current like-for-like successor for a new design; reassess the required optical speeds and interface count rather than treating either discontinued successor as a current product.
