SG200-18-K9-NA is a Cisco Small Business 200 smart managed switch with 16 Gigabit access ports and two 1G copper/SFP combo uplinks. Its Layer 2 switching role covers VLAN-based access and web configuration without a routed access license. Attached endpoints need their own power source. The full-width 1U chassis fits a rack with an internal AC supply. Fixed uplink positions may use supported fiber optics where present, so the fiber type and corresponding transceiver must be specified on the order. The SG200-18 port count and uplink class should match the installed network map. This retired platform is most appropriate where an existing configuration or spare requirement calls for the same hardware family.

36 Gbps switching capacity and 26.78 Mpps forwarding are the published model figures for frame movement and 64-byte packets. SG200-18-K9-NA uses 128 MB of CPU memory and 16 MB of flash for its embedded management software. VLAN configuration, spanning tree, LACP, and monitoring allow port-level control at the small business access edge. This 200 Series unit has no hardware stacking capability and no dynamic routing tier. Unpowered access ports carry data only, leaving endpoint power to other equipment. Fanless cooling avoids a replaceable fan in the enclosure. The internal universal AC supply has no standard hot-swappable redundant bay. Confirm that the Rack-Mount 1U installation has enough clearance for the chassis and that the local power connection matches Internal AC PSU. Keep the existing port map, VLAN plan, management settings, and configuration backup available while staging this exact replacement hardware for a production site.
ORM Systems offers SG200-18-K9-NA new sealed and certified refurbished, with purchase orders accepted in both conditions. Certified refurbished managed units are inspected, bench-tested, firmware verified, and wiped to factory default; every copper port is checked for a link at its rated speed. SFP bay recognition is checked for the built-in optic positions. Confirm Cisco order number SLM2016T-NA, regional power hardware, and any needed fiber optic before releasing the order. New units carry up to a 3-year extended ORM warranty, refurbished units up to 1 year, and both have 30-day returns subject to terms. Volume buying can use PO acceptance, Net-30 for government, UK/EU/US/MEA regional stock, and RMA with advance replacement.

An installed small business network requires 16 Gigabit copper access ports with the same port density. SG200-18-K9-NA offers two 1G copper/SFP combo uplinks and unpowered copper endpoints. Check patch-panel assignments, the actual Cisco PID SLM2016T-NA, and the local power connection before the purchase order.
A distribution handoff uses fiber rather than copper while 16 Gigabit endpoints remain attached. SG200-18-K9-NA provides two 1G copper/SFP combo uplinks. The shared combo positions accept a supported MGBSX1 or MGBLX1 optic, which disables the paired copper interface. Confirm the optic, fiber type, and uplink port assignment before the PO.
A branch retains a Cisco 200 Series configuration and needs a spare to cover a failed chassis. SG200-18-K9-NA is a retired Smart Managed model; its port map and external or internal power arrangement should match the installed unit. Stage a boot test and configuration backup before releasing the PO.
Current Cisco service entitlement
Cisco lists the Small Business 200 family as retired. Specify a currently supported Cisco switch when vendor software maintenance or a new service contract is required.
Faster distribution interface
SG200-18 provides 1G uplinks. Choose a current platform with a faster documented uplink class when the distribution link exceeds that rate.
One hardware stack control plane
SG200-18 has no hardware stack ports or common stack control plane. Select a current stackable platform if several chassis must operate as one managed system.
Switch powered network endpoints
The 16 access ports provide no PoE output. Select a current powered access model when phones, cameras, or wireless devices require switch-supplied power.

SG200-18-K9-NA identifies the Cisco SG200-18 16-port Gigabit switch. Its Cisco regional ordering number is SLM2016T-NA; the catalog spelling may differ from the physical order PID on older 200 Series units. Check the chassis label, sales region, and powered-port configuration before accepting a substitution.
SG200-18-K9-NA is smart managed through the 200 Series web interface. The platform supports VLAN and port controls, with SNMP monitoring on applicable models. Save the installed configuration and verify firmware before a refurbished unit replaces production hardware. Verify the actual chassis label, required media, and saved configuration before the purchase order.
SG200-18-K9-NA belongs to Cisco's retired Small Business 200 family. Cisco's retired products no longer receive normal vendor support. Existing stock or certified refurbished units can replace deployed hardware, but the purchase plan should include firmware availability, a tested spare, and a separate RMA route.
SG200-18-K9-NA is offered by ORM Systems new sealed or certified refurbished. New units have up to a 3-year extended ORM warranty; certified refurbished units have up to 1 year. Both conditions have 30-day returns subject to terms. Cisco's original limited lifetime hardware coverage ended when the platform was retired.
SG200-18-K9-NA does not supply PoE on its 16 Gigabit copper access ports. Powered devices need another switch or a separate power source. Its uplink ports are data interfaces, not power outputs. Confirm the endpoint power plan before ordering a non-PoE replacement for an existing installation.
SG200-18-K9-NA provides two 1G copper/SFP combo uplinks. Its published uplink speed class is 1G, and optical modules must be matched to the installed fiber. Verify the active uplink media and the distribution switch's matching interface before purchase. Verify the actual chassis label, required media, and saved configuration before the purchase order.
SG200-18-K9-NA cannot form a true hardware stack. Multiple 200 Series switches may be connected over Ethernet but retain separate management and configuration. The chassis does not include dedicated stack ports or a stack cable. Keep a separate backup and spare-unit record for each installed switch.
SG200-18-K9-NA is a Layer 2 Smart Managed switch rather than a routed access platform. It provides VLAN-based switching and browser configuration, while an upstream router or Layer 3 switch handles inter-VLAN paths. Confirm where the existing network gateway resides before replacing another device with this model.
SG200-18-K9-NA uses internal ac psu with a 100–240V AC supply connection. The published maximum draw is 22.9W for the documented configuration. Confirm the regional cord or adapter and local rack capacity before purchase. Verify the actual chassis label, required media, and saved configuration before the purchase order.
SG200-18-K9-NA has a published 36 Gbps switching capacity and a separate 26.78 Mpps forwarding rate for small packets. These figures describe this model rather than another member of the family. They should be compared with the existing uplink layout and access-port speeds when checking replacement suitability.
