SF220-24-K9 is a fanless Layer 2 smart switch with 24 10/100 Mbps access ports and two fixed Gigabit combo uplinks for small-business networks. Each uplink offers a copper connection or an SFP cage, with only one side active at a time. The non-PoE design carries data to externally powered endpoints rather than delivering endpoint power through Ethernet. A full-width 1U chassis places the hardware in an equipment rack. Within Cisco 220 Series Smart Switches, the discontinued SF220-24P-K9-NA adds PoE+ for legacy installations requiring powered connections. The SF220-24 configuration serves buyers retaining Fast Ethernet access while keeping Gigabit connections toward the rest of the network; its combo architecture lets the uplink medium follow the existing cabling without a removable uplink card.

8.8 Gbps switching capacity and 6.55 Mpps forwarding at 64-byte packet size define the traffic envelope for the access and uplink connections. An 8192-entry MAC table bounds learned forwarding addresses, while a dynamically shared 4.1 Mb packet buffer holds queued traffic across the ports. SF220-24-K9 carries 128 MB of memory and 32 MB of flash for its operating software and configuration. STP/RSTP/MSTP control bridged loops, and LACP supports link aggregation with eight groups and eight active ports per group. Eight hardware queues per port support traffic prioritization, while access control lists allow 512 rules for filtering. Browser management, a scriptable CLI and SNMP provide local and remote administration paths. IPv4/IPv6 dual-stack management does not turn the hardware into a Layer 3 router. Energy Efficient Ethernet and Energy Detect reduce consumption when links are lightly used or down; the published consumption figures also differ with input voltage.
Order SF220-24-K9 new sealed or certified refurbished, and specify the regional version, required accessories and quantity on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition and PSU status; firmware is verified and the configuration is wiped to factory default. ORM's new-unit warranty is up to a 3-year extended warranty, certified refurbished coverage is up to 1 year, and both conditions include 30-day returns, with terms applying. Enterprise and volume orders support POs, government Net-30 and RMA with advance replacement through UK, EU, US and MEA regional stock and RMA coverage.

An existing installation built around SLM224GT-NA needs a replacement for failed hardware rather than a change in switching architecture. That older part reached end-of-sale on October 4, 2018. Match the regional replacement, review the saved configuration and confirm the required mounting hardware before issuing the purchase order.
A multi-site rollout needs separate guest, office and voice segments without changing the configuration method between locations. The switch supports 256 simultaneous VLANs and text-editable configuration files that can be downloaded to another unit. Define common settings, site-specific addressing and the validation checklist before ordering the batch.
A troubleshooting bench needs to observe traffic from several attached devices while retaining a consistent capture workflow. Port mirroring supports eight source ports to one destination, with four sessions available. Confirm which links need observation, reserve the analyzer connection and specify the required bench quantity before the purchase order.
Gigabit connections on every access port
Access links stop at 100 Mbps. CBS220-24T-4G-NA provides 24 Gigabit access ports and four 1G SFP uplinks for buyers replacing the older North American hardware.
Ethernet power for attached endpoints
The access ports provide data but no endpoint power. CBS220-24P-4G-NA is the regional replacement when Ethernet-delivered power is required; it also changes access speed to Gigabit.
10G uplinks to distribution
The fixed combo uplinks operate at 1G, and the chassis has no removable uplink-card bay. A requirement for 10G distribution links exceeds this configuration.

SF220-24-K9 identifies the 220 Series Fast Ethernet smart switch with 24 access ports and two Gigabit combo uplinks. SF220 selects the Fast Ethernet model group, and 24 gives the access-port count. SF220-24-K9-NA adds the North American regional ending to the catalog form.
SF220-24-K9 supports HTTP/HTTPS browser management, a console CLI, remote CLI over SSH or Telnet, SNMP and Cisco FindIT management. SNMP versions 1, 2c and 3 are supported. Cisco FindIT Network Manager and Probe provide network management, while Cisco FindIT Network Discovery Utility assists device discovery and initial access.
SF220-24-K9 is discontinued: end-of-sale was July 30, 2022, and Cisco's last date of support is July 31, 2027. Software maintenance ended July 30, 2023. CBS220-24T-4G-NA replaces the North American regional form; buyers should align the purchase with the remaining support window and their migration schedule.
SF220-24-K9 is offered new sealed with up to a 3-year extended ORM warranty, or certified refurbished with up to 1 year. Both conditions have 30-day returns; terms apply. Cisco's limited lifetime hardware warranty excludes power supplies beyond 1 year, and Cisco service ends July 31, 2027.
SF220-24-K9 replaced the discontinued SLM224GT-EU, SLM224GT-NA and SLM224GT-UK regional SF200-24 models. Those older parts reached end-of-sale on October 4, 2018. Match the original region when selecting a replacement; this switch is also discontinued, so new installations should distinguish legacy sparing from migration planning.
SF220-24-K9 has two fixed 1G combo uplinks, each pairing a copper RJ-45 connector with an SFP cage. Only one connector in each pair can be active at a time. The configuration therefore provides two usable uplink connections, not four independently active copper and fiber links.
Cisco 220 Series Smart Switches support MGBSX1 for multimode fiber to 550 m and MGBLX1 for single-mode fiber to 10 km. Both operate at 1G. Select the optic to match the cable medium and required distance, and specify the required transceivers separately from the switch.
No, SF220-24-K9 is a Layer 2 smart switch rather than an inter-VLAN router. VLAN separation and IPv4/IPv6 management do not provide routed forwarding between subnets. Networks requiring routing need a separate routing device; assigning an IP management address does not change the switch's forwarding role.
Cisco 220 Series Smart Switches include a rack-mounting kit, and the SF220-24 configuration occupies 1U. The chassis measures 440 mm wide, 44 mm high and 201 mm deep, with a weight of 2.6 kg. Confirm the mounting accessories included with the selected order condition.
SF220-24P-K9-NA adds PoE+ with a shared 180W budget, while SF220-24-K9 supplies data only. Both models are discontinued. The unpowered model suits externally powered endpoints; the powered variant fits legacy spares requiring Ethernet-delivered endpoint power, subject to its shared budget rather than unrestricted power on every port.
SF220-48-K9-NA offers 48 Fast Ethernet access ports compared with 24 on SF220-24-K9. Both models are discontinued. The smaller unit fits legacy replacements with fewer connections; the higher-density variant fits existing installations retaining more access links, after confirming that Fast Ethernet remains acceptable for the attached endpoints.
CBS220-24T-4G-NA provides Gigabit access ports, whereas SF220-24-K9 limits access links to 10/100 Mbps. CBS220-24T-4G-NA is the replacement for the discontinued North American model. Existing Fast Ethernet spares requirements favor the older hardware; buyers standardizing on Gigabit endpoint connections should specify the successor and verify the regional order.
SF220-24-K9-NA-RF is Cisco-remanufactured hardware, not a designation for ORM's certified refurbishment. The NA ending identifies the North American form, while RF identifies the remanufactured order. Specify Cisco remanufacturing explicitly when required; an ORM certified refurbished order follows ORM's inspection and bench-testing process instead.
