SF250-24-K9-NA is a fanless, smart-managed access switch with 24 Fast Ethernet connections and four fixed Gigabit uplinks. Two uplinks provide dedicated SFP connectivity; two offer shared copper/SFP connections. This non-PoE member of the Cisco 250 Series Smart Switches uses a full-width rack-mount chassis. Its endpoint connections operate at 10/100 Mbps, so Gigabit uplinks do not make the access ports Gigabit-capable.

12.8 Gbps switching capacity and 9.52 Mpps forwarding support traffic across the built-in interfaces. SF250-24-K9-NA supports static IPv4 routing rather than a dynamic routing feature set. STP/RSTP/MSTP and LACP provide loop-control and link-aggregation options.
Order SF250-24-K9-NA new sealed or certified refurbished, specifying condition and quantity on the PO. Refurbished units are inspected and bench-tested for power-on, POST, rated-speed port links, clean boot, optics bay recognition and PSU status; firmware is verified and configurations are wiped to factory default. New units carry up to a 3-year extended ORM warranty, certified refurbished units up to 1 year, and every condition includes 30-day returns, terms apply. For enterprise and volume orders, ORM accepts POs, provides Net-30 for government, and offers RMA with advance replacement through UK, EU, US and MEA regional stock/RMA operations.

When replacing a failed SLM224GT-NA, this model follows the named replacement relationship rather than requiring an unrelated switch selection. Treat the replacement as a configuration migration, not an assumption of identical settings. Before the PO, specify the required condition and arrange a configuration review.
When maintaining an existing installation while planning its replacement, separate immediate spare requirements from the longer-term migration purchase. The successor chain reaches C1200-24T-4G through the discontinued CBS250-24T-4G-NA. Before ordering legacy spares, establish the migration schedule and the quantity needed to cover the remaining installation period.
Gigabit connections for every endpoint
The access connections stop at 100 Mbps. C1200-24T-4G provides 24 Gigabit access connections and is the current endpoint of the successor chain.
Power delivery to connected endpoints
The switch does not supply PoE. C1200-24P-4G is a powered alternative that also changes the access connections from Fast Ethernet to Gigabit Ethernet.

SF250-24-K9-NA identifies the Fast Ethernet 250-family model with 24 access ports. NA selects the regional version covering the United States and other designated American markets; K9 remains part of the complete ordering identifier.
SF250-24-K9-NA supports HTTP/HTTPS browser management, Textview CLI with SSH/Telnet access, SNMP, Smart Network Application, FindIT Network Manager with an embedded probe, and Cisco Active Advisor.
SF250-24-K9-NA is discontinued: Cisco sales ended July 30, 2022. Software maintenance ended July 30, 2023, and the final support date is July 31, 2027.
SF250-24-K9-NA is offered new sealed or certified refurbished. ORM provides new units with up to a 3-year extended warranty and refurbished units with up to 1 year; returns are 30 days on every condition, terms apply. Cisco's limited lifetime hardware warranty is bounded by July 31, 2027.
SF250-24-K9-NA replaces SLM224GT-NA, the SF200-24 model. Existing configuration and connection requirements should be reviewed before treating the replacement as a direct operational substitute.
SF250-24P-K9-NA adds PoE+ output; SF250-24-K9-NA does not power endpoints. Both are discontinued, so the distinction primarily matters when matching an existing installation's endpoint-power requirements.
SF250-48-K9-NA has 48 Fast Ethernet access connections, compared with 24 on SF250-24-K9-NA. Both are discontinued; the higher-density model addresses installations requiring more endpoint connections.
C1200-24T-4G provides Gigabit access connections where SF250-24-K9-NA provides Fast Ethernet. The legacy model serves existing installations; C1200-24T-4G is the current successor-chain choice for Gigabit endpoint access.
The 250 Smart Switches support 32 static IPv4 routes and 16 IP interfaces. That capability supports limited routing requirements rather than dynamic route exchange.
SF250-24-K9-NA provides four Gigabit uplinks: two dedicated SFP connections and two copper/SFP combo connections. Each combo connection uses copper or fiber, not both simultaneously.
