CBS250-24P-4G-NA is a fanless, Layer 2+ smart-managed switch with 24 Gigabit Ethernet PoE+ access ports and four fixed 1G SFP uplinks. Its full-width 1U rack chassis combines powered copper connections with dedicated fiber connections for small-business access networks. The Cisco Business 250 Series connects computers, IP phones, and wireless access points using an internal AC supply rather than an external adapter. The discontinued CBS250-24FP-4G-NA increases the PoE allocation to 370W while retaining the same access-port density. Copper connections negotiate 10, 100, or 1000 Mbps, accommodating older Ethernet devices alongside Gigabit endpoints.
CBS250-24P-4G-NA price for new stock is $626.85, a 47% saving from the Cisco list price of $1,182.15. CBS250-24P-4G-NA refurb price is $500.85. CBS250-24P-4G-NA is in stock and available for next-day dispatch. (terms applied)

56 Gbps switching capacity supports nonblocking forwarding across the installed interfaces, while 41.66 Mpps specifies performance with minimum-size packets. 195W of shared PoE power requires endpoint allocation rather than simultaneous maximum output from every powered port. Static routing supports 32 routes and 16 IP interfaces for locally configured inter-VLAN connectivity. CBS250-24P-4G-NA maintains 8000 MAC addresses and shares a 1.5 MB packet buffer across its ports. STP, RSTP, MSTP, and LACP provide loop control and link aggregation. Management includes a browser interface, CLI over SSH or Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. Dual firmware images support software maintenance, while cable diagnostics and syslog assist troubleshooting. 239.7W worst-case consumption with PoE provides the upper input-power figure for sizing UPS capacity and electrical provision.
For CBS250-24P-4G-NA, select new sealed or certified refurbished condition and specify quantities and required accessories on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, every port linking at rated speed, PoE output under load on every powered port, optics bay recognition, and PSU status; firmware is verified and configuration is wiped to factory default. ORM provides up to 3-year extended warranty on new units and up to 1 year on certified refurbished units, plus 30-day returns on every condition, terms apply; Cisco's separate limited lifetime warranty remains subject to eligibility and ends October 31, 2029. For enterprise and volume orders, POs are accepted, Net-30 is available for government, and RMA includes advance replacement.

Replacement PID | C1200-24P-4G |
When a discontinued SF250-24P-K9-NA needs replacement, its July 30, 2022 end-of-sale date provides a clear starting point for the refresh record. Treat the change as a new installation rather than assuming physical connections or saved settings transfer unchanged; specify the required configuration and cabling checks before the purchase order.
When several branches need a common initial configuration, text-editable configuration files can be downloaded to another switch, and SCP file download supports protected staging. Separate shared settings from each site's addressing and port assignments, then specify the configuration handoff, administrative access requirements, and staging acceptance checks before ordering.
When a lab or staging bench needs packet inspection before equipment enters service, port mirroring supports four source ports feeding one destination port. Allocate the analyzer connection before finalizing the port plan, identify the traffic that must be captured, and specify the capture and verification procedure with the order.
10G fiber uplinks to distribution
The fixed SFP uplinks operate at 1G and cannot provide 10G connectivity. C1200-24P-4X is the current migration option with four 10G SFP+ uplinks.
Maximum power on every endpoint
The 195W shared budget cannot supply 30W simultaneously across all 24 powered ports. Specify an alternative whose total PoE allocation meets the complete endpoint load.
Continuing Cisco security maintenance
Vulnerability and security support ended October 29, 2025, before the final hardware-support milestone. C1200-24P-4G is the current migration product for replacement planning.

CBS250-24P-4G-NA identifies a Cisco Business 250 switch: 24P denotes 24 Gigabit PoE+ access ports, and 4G denotes four Gigabit SFP uplinks. NA is the regional ordering suffix covering the United States, Canada, Mexico, Colombia, Chile, and the rest of Latin America; it is not a software license tier.
CBS250-24P-4G-NA supports browser management over HTTP or HTTPS, CLI access over SSH or Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. An embedded Dashboard probe avoids a separate probe appliance. Cisco Network Plug and Play with PnP Connect also supports initial provisioning.
CBS250-24P-4G-NA provides a shared 195W PoE budget across 24 powered ports, with a maximum of 30W on an individual port. The per-port maximum is not available simultaneously everywhere. Add the required allocations for phones, access points, and other powered devices before approving the endpoint schedule.
CBS250-24P-4G-NA supports Gigabit transceivers including MGBSX1 for multimode fiber and MGBLX1 for single-mode fiber. MGBSX1 supports distances of 500 m, while MGBLX1 supports 10 km. Select the transceiver against the installed fiber, required reach, and remote interface, and include the required quantity separately on the order.
Cisco Business 250 switches support static routing between IP interfaces, with 32 static routes and 16 IP interfaces. That makes the series suitable for a bounded, manually configured routing plan rather than a requirement for dynamic route exchange. Verify the complete interface and destination requirements before standardizing the configuration.
CBS250-24P-4G-NA is a fanless, full-width 1U rack-mount switch measuring 445 mm wide, 299 mm deep, and 44 mm high. Its weight is 3.53 kg. Check the rack's usable depth and cable clearance, and confirm that the mounting hardware is included in the selected condition's supplied contents.
CBS250-24P-4G-NA reached end of sale on October 29, 2024, and its last date of support is October 31, 2029. Software maintenance and vulnerability support ended October 29, 2025. The remaining hardware-support period therefore does not imply continuing security fixes, and support remains subject to applicable entitlement.
CBS250-24P-4G-NA replaces SG250-26P-K9-NA and SF250-24P-K9-NA in their respective migration paths. SG250-26P-K9-NA reached end of sale on October 30, 2021; SF250-24P-K9-NA followed on July 30, 2022. Both predecessors are discontinued, and the CBS250 replacement is also discontinued, so distinguish legacy sparing from a new equipment standard.
CBS250-24P-4G-NA provides a 195W PoE budget, whereas CBS250-24FP-4G-NA provides 370W. Both models are discontinued. The lower-budget model suits legacy installations with smaller aggregate powered loads; the higher-budget model suits larger allocations. Compare the complete endpoint demand rather than assuming that identical powered-port counts imply identical power availability.
CBS250-24P-4G-NA has four fixed 1G SFP uplinks, while CBS250-24P-4X-NA has four fixed 10G SFP+ uplinks. Both models are discontinued. The 4G version fits legacy Gigabit uplink requirements; the 4X version addresses legacy installations requiring faster uplinks. Match replacement equipment to the existing optics and upstream connections.
CBS250-24P-4G-NA is discontinued, while C1200-24P-4G is its current Catalyst 1200 migration product. Both configurations provide 24 Gigabit powered access ports and four Gigabit SFP uplinks. The CBS250 model addresses existing equipment standards and spare requirements; C1200-24P-4G is the migration choice when establishing a replacement purchasing standard.
ORM offers CBS250-24P-4G-NA new sealed or certified refurbished. ORM's new warranty is up to 3-year extended; certified refurbished coverage is up to 1 year. Returns are 30 days on every condition, terms apply. Cisco's separate limited lifetime warranty is subject to eligibility, with service ending October 31, 2029.
