SG300-10SFP-K9-NA is a fanless managed desktop switch with eight dedicated Gigabit SFP ports and two Gigabit copper/SFP combo uplinks for fiber-facing small-business networks. Ten logical connections can operate simultaneously, with either copper or fiber active on each combo connection. Layer 2+ functionality combines Ethernet switching with static IPv4 routing, while the non-PoE design connects equipment without supplying endpoint power. The Small Business 300 family serves business networks requiring configurable switching rather than unmanaged connectivity. The discontinued SRW2008-K9 changes the eight dedicated access connections to Gigabit copper. This 10-port Gigabit managed SFP switch instead concentrates its access connectivity on fiber interfaces.

20 Gbps switching capacity provides a nonblocking fabric for the installed interfaces. 14.88 Mpps forwarding performance applies to 64-byte packets, providing a separate sizing measure for traffic dominated by short frames. 18.1W maximum consumption at 110V AC establishes the switch load for power planning; the external adapter accepts 100–240V AC input. SG300-10SFP-K9-NA carries 128 MB of CPU memory and 16 MB of flash for its control software and stored configuration. A shared 8 Mb packet buffer allocates storage dynamically across ports rather than assigning the entire buffer to one connection. HTTP/HTTPS provides browser-based configuration, while SNMP versions 1, 2c, and 3 support management-system integration. SSH and Telnet provide remote session access. 512 static IPv4 routes and 128 IP interfaces bound routed configurations; routing entries must be provisioned explicitly. Uplink expansion through removable network cards is not supported. The operating range is 0°C to 45°C, so enclosure temperature remains a deployment constraint.
SG300-10SFP-K9-NA is offered new sealed or certified refurbished, with ORM warranty up to 3-year extended on new units or up to 1 year on refurbished units, plus 30-day returns on every condition; terms apply. Refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, and optics bay recognition. Specify the condition, transceiver PIDs, and supplied external adapter on the PO; Cisco's limited lifetime hardware coverage and service ended October 31, 2023. For enterprise and volume orders, submit quantities and conditions; PO accepted, Net-30 for government, and RMA with advance replacement across UK / EU / US / MEA.

When refreshing existing fiber links, transceiver selection depends on the installed fiber and path length rather than total connection count. MGBSX1 supports multimode links to 300 m, while MGBLX1 supports single-mode links to 10 km. Specify the matching transceiver PID and fiber requirements for each link before issuing the PO.
When replenishing spares for an installed fleet, configuration state matters alongside the hardware match. ORM's certified refurbished managed units have firmware verified and configurations wiped to factory default, so production settings must be restored during staging. Specify the required condition and keep the deployment configuration available before issuing the PO.
Uplinks faster than Gigabit Ethernet
The fixed combo uplinks operate at Gigabit Ethernet speed. Requirements above 1 Gbps per uplink exceed this switch's interface capability, and removable uplink cards cannot extend it.
Direct power for connected endpoints
SG300-10SFP-K9-NA provides no PoE output. Connected phones, access points, or cameras that require power through their Ethernet connection need a separate power source.
Active Cisco service coverage
Cisco service ended October 31, 2023. The subsequent fiber-switch replacement line also reaches discontinued hardware without a current migration product, rather than an orderable direct successor.

SG300-10SFP-K9-NA identifies a 300-family Gigabit managed SFP switch with ten logical connections: eight dedicated SFP ports and two copper/SFP combo ports. SG300-10SFP is the model name; retain the complete K9-NA ordering form when matching an existing unit or preparing a purchase order.
SG300-10SFP-K9-NA supports browser management through HTTP/HTTPS, remote SSH or Telnet sessions, and SNMP versions 1, 2c, and 3. The browser interface covers configuration, monitoring, system maintenance, and a system dashboard. SNMP provides integration with a network management station rather than requiring browser-only administration.
SG300-10SFP-K9-NA is discontinued, and Cisco service ended October 31, 2023, following end of sale on October 4, 2018. Its original replacement, SG350-10SFP-K9-NA, is also discontinued. The later CBS350-8S-E-2G-NA is discontinued as well, with no current migration product in that fiber-switch replacement line.
ORM offers SG300-10SFP-K9-NA new sealed or certified refurbished, with up to 3-year extended warranty on new units and up to 1 year on refurbished units. Every condition has 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty and service ended October 31, 2023, so ORM coverage is separate.
The 10-port Gigabit managed SFP switch supports ten simultaneous logical connections through eight dedicated SFP interfaces and two combo interfaces. Each combo interface selects either its copper connector or its SFP cage. Connecting both media to one combo interface does not create an additional usable port.
The Small Business 300 switch supports MGBSX1 for Gigabit multimode fiber and MGBLX1 for Gigabit single-mode fiber, among its supported SFP options. MGBSX1 has a 300 m maximum distance, while MGBLX1 reaches 10 km. Match the transceiver PID, fiber type, and link distance before specifying each connection.
Yes, SG300-10SFP-K9-NA supports static IPv4 routing with up to 512 static routes and 128 IP interfaces. Routed operation requires the appropriate system configuration rather than merely connecting devices to different ports. This is static routing, so route entries must be maintained explicitly instead of learned through a dynamic routing protocol.
SG300-10SFP-K9-NA uses an external AC adapter accepting 100–240V AC at 50–60 Hz, with maximum switch consumption of 18.1W at 110V AC. Consumption at 220V AC is 17.71W. Include the external adapter in the order requirements rather than treating the unit as an internally powered chassis.
The Small Business 300 fiber switch measures 279.4 mm wide, 44.45 mm high, and 170 mm deep, weighs 2.125 kg, and uses fanless cooling. Its operating temperature range is 0°C to 45°C. The published MTBF is 132151 hours at 45°C; that reliability figure is not a service-life guarantee.
SG300-10SFP-K9-NA has eight dedicated Gigabit SFP access interfaces, whereas SRW2008-K9 has eight dedicated Gigabit copper interfaces. Both retain two Gigabit copper/SFP combo connections, and both are discontinued. The SFP model matches existing fiber access links; SRW2008-K9 matches existing copper access cabling when maintaining an installed network.
SG300-10SFP-K9-NA provides no endpoint power, whereas SRW2008P-K9 supplies PoE through eight Gigabit copper ports using a shared 62W budget. Both models are discontinued, and their access media also differ. The SFP model serves fiber-connected equipment; SRW2008P-K9 serves an existing copper installation requiring powered endpoint connections.
SG300-10SFP-K9-NA uses an external AC adapter, whereas SG300-28SFP-K9 uses an internal universal AC supply. Both are discontinued members of the same managed-switch family. The compact model suits an installed network using an external adapter; SG300-28SFP-K9 suits an existing installation standardized on an internally powered fiber switch.
