CBS250-24T-4G-NA provides fanless, Layer 2+ smart-managed access through 24 Gigabit copper ports and four fixed 1G SFP uplinks. The non-PoE configuration connects independently powered computers, printers, servers, and other business equipment without allocating a budget for endpoint power. Its full-width 1U chassis fits a standard equipment rack, while dedicated fiber connections leave the copper access ports available for endpoints. The Cisco Business 250 Series combines configurable switching with static routing for small-business networks that require more control than an unmanaged switch. The discontinued CBS250-24P-4G-NA differs by adding PoE+ output with a shared 195W budget. Voice VLAN functionality separates voice traffic, while port security restricts learned source addresses on individual connections. The fixed uplink architecture does not require a removable network card.

56 Gbps switching capacity accommodates traffic across the built-in interfaces, and 41.66 Mpps forwarding supports packet handling at the switch’s rated performance. Static IPv4 routing supports 32 routes and 16 IP interfaces for locally configured inter-network forwarding rather than dynamic route exchange. CBS250-24T-4G-NA carries 512 MB of DRAM and 256 MB of flash for its operating software and configuration resources. A dynamically shared 1.5 MB packet buffer absorbs traffic bursts across the ports, while eight hardware queues support differentiated traffic scheduling. STP/RSTP/MSTP provide loop-control options, and LACP supports four aggregation groups with eight active ports per group. Browser configuration, a full or menu-based CLI, and SNMP provide local and remote administration paths. Dual software images support firmware maintenance without replacing the stored fallback image. 25.91W worst-case consumption at 110V AC provides the equipment-load figure for power planning; the corresponding figure at 220V AC is 25.63W.
ORM Systems offers CBS250-24T-4G-NA new sealed or certified refurbished, with up to a 3-year extended warranty on new units, up to 1 year on certified refurbished units, and 30-day returns on every condition; terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, clean boot, rated-speed links on every port, optics bay recognition, and PSU status, with firmware verified and configurations wiped to factory default. Specify the condition, quantity, required transceivers, and mounting accessories before submitting the PO; Cisco’s separate Limited Lifetime warranty remains bounded by October 31, 2029. Enterprise and volume orders can use accepted POs, Net-30 for government, regional stock and RMA across the UK, EU, US, and MEA, and RMA with advance replacement.

When replacing a discontinued SF250-24-K9-NA or SG250-26-K9-NA, treat the purchase as a migration rather than an identical-port exchange. Both older part numbers lead to this model. Reconcile existing copper connections, fiber connections, configuration requirements, and the intended maintenance window before specifying the replacement quantity on the purchase order.
When several small-business sites need a common provisioning workflow, the embedded Cisco Business Dashboard probe removes the need for a separate probe appliance at each location. Network Plug and Play also supports device provisioning. Choose the management workflow and identify the required site configuration before finalizing the hardware order.
When a staging environment needs packet capture before equipment enters service, port mirroring can send traffic from four source ports to one destination port. The destination connection must be reserved for the analyzer. Specify the capture connection, source-port assignments, and required test equipment before approving the staging purchase order.
PoE power for connected endpoints
CBS250-24T-4G-NA supplies no endpoint power. C1200-24P-4G is the current 24-port PoE alternative with four 1G SFP uplinks for connections that also require switch-delivered power.
10G connections to upstream switches
The fixed SFP uplinks operate at 1G, not 10G. C1200-24T-4X provides four 10G SFP+ uplinks while retaining 24 Gigabit copper access ports.
Continuing manufacturer security software releases
Software maintenance and security support ended October 29, 2025. C1200-24T-4G is the current migration replacement for buyers avoiding this discontinued model’s completed software-support milestones.

CBS250-24T-4G-NA identifies a Cisco Business 250 smart switch: 24 denotes 24 Gigabit copper access ports, T identifies the non-PoE configuration, and 4G denotes four Gigabit SFP uplinks. NA is the regional suffix used for the United States, Canada, Mexico, Colombia, Chile, and the rest of Latin America.
CBS250-24T-4G-NA supports a web UI over HTTP/HTTPS, full or menu-based CLI through the RJ-45 console and SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP v1/v2c/v3. An embedded Dashboard probe avoids a separate probe appliance, while Network Plug and Play supports automated provisioning.
CBS250-24T-4G-NA is discontinued, with end of sale on October 29, 2024. Software maintenance and vulnerability/security support ended October 29, 2025. The last date for applicable Cisco service and support is October 31, 2029, and C1200-24T-4G is the current migration replacement.
CBS250-24T-4G-NA is offered new sealed or certified refurbished by ORM Systems. ORM provides up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units, with 30-day returns on either condition; terms apply. Cisco’s separate Limited Lifetime warranty is bounded by October 31, 2029.
No license or subscription is required for CBS250-24T-4G-NA’s included features. All functionality comes with the hardware purchase, so the order does not need a feature-license tier or minimum software subscription term. Selecting certified refurbished hardware does not introduce a separate subscription requirement for those features.
CBS250-24T-4G-NA replaces SG250-26-K9-NA and SF250-24-K9-NA. SG250-26-K9-NA reached end of sale October 30, 2021, while SF250-24-K9-NA reached end of sale July 30, 2022. Both predecessors are discontinued, and the subsequent migration from this Business 250 model leads to C1200-24T-4G.
CBS250-24T-4G-NA provides no PoE output, whereas CBS250-24P-4G-NA adds PoE+ across 24 ports with a shared 195W budget. Both models are discontinued. The T model suits independently powered equipment; the P model addresses endpoint-power requirements when maintaining an existing Business 250 installation.
CBS250-24T-4G-NA has 24 copper access ports, while CBS250-48T-4G-NA has 48; both retain four Gigabit SFP uplinks and are discontinued. The 24-port model suits a smaller connection count, while the 48-port model accommodates more independently powered endpoints within an existing Business 250 installation.
CBS250-24T-4G-NA is the discontinued Business 250 model, while C1200-24T-4G is its current Catalyst 1200 migration replacement. Both configurations provide 24 Gigabit copper ports and four Gigabit SFP uplinks. The older model suits installed-base matching; the replacement suits buyers moving to the successor family.
The Business 250 switch supports static IPv4 routing with 32 routes and 16 IP interfaces, giving CBS250-24T-4G-NA Layer 2+ capability. Routes require local configuration rather than dynamic route exchange. Size the intended routed interfaces and destination networks against those limits before assigning the switch an inter-network forwarding role.
The 24-port Gigabit CBS250-24T-4G-NA supports 1G SFP transceivers including GLC-SX-MMD for multimode fiber to 550 m and GLC-LH-SMD for single-mode fiber to 10 km. Match the selected transceiver to the fiber plant and far-end equipment; the fixed uplinks do not operate at 10G.
CBS250-24T-4G-NA uses an internal universal 100-240V AC supply without a redundant PSU option. Worst-case consumption is 25.91W at 110V AC or 25.63W at 220V AC. The package includes a power cord, so the electrical order requires an AC connection rather than an external power adapter.
