CBS250-48T-4X is a Layer 2+ smart-managed access switch with 48 Gigabit copper ports and four fixed 10G SFP+ uplinks for small-business networks. The non-PoE configuration connects independently powered computers, printers, and servers; phones, cameras, and wireless access points require their own power arrangements. A full-width 1U chassis places this Cisco Business 250 Series model in a standard equipment rack. The uplink architecture uses built-in cages rather than a removable network card, keeping the port configuration fixed. The discontinued CBS250-48P-4X differs by supplying PoE+ with a shared 370W endpoint-power budget. Buyers retaining existing equipment can use the non-powered configuration where endpoint connectivity, rather than Ethernet-delivered power, determines the replacement requirement.
CBS250-48T-4X price for new stock is $1,036.35, a 32.7% saving from the Cisco list price of $1,539.00. CBS250-48T-4X refurb price is $290.85. CBS250-48T-4X is in stock and available for next-day dispatch. (terms applied)

176 Gbps switching capacity provides nonblocking forwarding across the fixed ports, while 130.94 Mpps supports wire-speed forwarding of minimum-size packets. 32 IPv4 static routes support internal subnet communication; dynamic route learning is not part of the routing feature set. CBS250-48T-4X carries 512 MB DRAM and 256 MB flash for its embedded software and configuration. A 3 MB packet buffer is dynamically shared across all ports, while the 8000-entry MAC table bounds learned addresses. STP/RSTP/MSTP provide Layer 2 loop control, and LACP supports four aggregation groups with eight active ports per group. Cisco Business 250 management includes web configuration, a scriptable full CLI, and SNMP for browser, command, and monitoring workflows. A single fan moves chassis air, so this model is not fanless. 51.01W worst-case consumption at 110V AC provides a circuit-sizing figure without an endpoint-power allowance. The internal universal supply accepts 100-240V AC.
ORM Systems offers CBS250-48T-4X in new sealed and certified refurbished condition, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units; returns are available for 30 days in either condition, terms apply. Certified refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, optics bay recognition, PSU status, and fan status, then firmware verified and wiped to factory default. Specify the condition, quantity, and required accessory PIDs on the purchase order. Enterprise and volume orders have PO acceptance, government Net-30, and RMA with advance replacement, with regional stock and RMA in the UK, EU, US, and MEA.

A branch adding separate user, voice, and device subnets should size the design against the 16 IP-interface limit before choosing this switch. Count planned gateway interfaces, reserve capacity for management, and place functions beyond that limit elsewhere in the design. Confirm the complete interface plan before approving the purchase order.
A multi-site rollout using reusable templates can standardize text-editable configuration files and provision through Cisco PnP Connect. Check that each site's intended design stays within 255 simultaneously active VLANs rather than assuming a larger campus-scale allowance. Specify the configuration template, management access plan, and regional order variant before the PO.
A staging lab collecting captures from several devices should plan around a maximum of four source ports mirrored to one destination port. Reserve the capture destination in the port map and agree which sources will be inspected together. Specify the monitoring connections and intended configuration before ordering the lab unit.
Ethernet power for connected endpoints
CBS250-48T-4X does not supply endpoint power over Ethernet. C1200-48P-4X provides a current 48-port Gigabit PoE alternative with four 10G SFP+ uplinks; size endpoint power requirements separately.
Multi-gigabit copper endpoint connections
CBS250-48T-4X copper access ports stop at 1Gbps. Its 10G capability resides in the SFP+ uplinks, not the endpoint ports, so this model cannot provide native multi-gigabit copper access.
Ongoing software and security fixes
CBS250-48T-4X-NA software maintenance and vulnerability/security support ended October 29, 2025. C1200-48T-4X is the current replacement with the same access port count and uplink speed.

CBS250-48T-4X identifies a Cisco Business 250 switch; 48T denotes 48 non-PoE 10/100/1000 copper access ports, and 4X denotes four 10 Gigabit SFP+ uplinks. The model is rack-mountable. For a US order, the complete regional part number is CBS250-48T-4X-NA; NA identifies the North American ordering region.
CBS250-48T-4X supports a web UI over HTTP/HTTPS, full or menu-based CLI through the console or SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app, and SNMP. The embedded Dashboard probe avoids a separate probe appliance. Network Plug and Play supports provisioning, while CLI privilege levels separate administrative access.
CBS250-48T-4X is discontinued; North American CBS250-48T-4X-NA reached end of sale October 29, 2024, with support ending October 31, 2029. Software maintenance and vulnerability/security support ended October 29, 2025. C1200-48T-4X is the replacement. Continued hardware support eligibility does not mean that new software fixes or security remedies remain available.
ORM Systems offers CBS250-48T-4X new sealed or certified refurbished: new carries up to a 3-year extended warranty, refurbished up to 1 year. Cisco's Limited Lifetime hardware warranty is bounded by the October 31, 2029 last support date. Both conditions have 30-day returns, terms apply; refurbished units are inspected, bench-tested, firmware verified, and factory-default wiped.
CBS250-48T-4X replaced discontinued SG250X-48 regional models: SG250X-48-K9-AR, SG250X-48-K9-AU, SG250X-48-K9-BR, SG250X-48-K9-EU, SG250X-48-K9-JP, SG250X-48-K9-NA, and SG250X-48-K9-UK. Their end-of-sale date was October 30, 2021, with support ending October 31, 2026. CBS250 is also discontinued, so C1200-48T-4X is the current model at the end of this replacement chain.
SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber work with Cisco Business 250 10G uplinks. SFP-10G-SR supports 26-400m depending on the fiber, while SFP-10G-LR supports 10km. The SFP+ cages also support 1G operation with compatible SFPs. Specify the exact transceiver PID and cable medium on the order.
Yes, CBS250-48T-4X supports IPv4 static routing with 32 routes and 16 IP interfaces, giving it a Layer 2+ classification. Interfaces can be configured on physical ports, VLANs, link aggregation groups, or loopbacks. The routing function connects internal subnets; its feature set is static rather than a dynamic routing package.
CBS250-48T-4X uses an internal universal AC supply accepting 100-240V AC at 50-60Hz, without an optional second internal redundant supply. The power cord is included in the base package. Worst-case system consumption is 51.01W at 110V AC or 50.58W at 220V AC, so specify the regional power cord for the receiving site.
Yes, the 48-port Gigabit CBS250-48T-4X is rack-mountable as a full-width 1U unit. The chassis measures 445 mm wide, 288 mm deep, and 44 mm high, with a 3.95 kg unit weight. A mounting kit is included in the base package. Confirm cable routing and ventilation before specifying the installation.
CBS250-48P-4X supplies PoE+ with a shared 370W budget, whereas CBS250-48T-4X does not power endpoints over Ethernet. Both retain 48 Gigabit access ports and four 10G SFP+ uplinks. These models are discontinued: the non-PoE model suits like-for-like data sparing; for new powered deployments, the current replacement is C1200-48P-4X.
CBS250-48T-4X has four 10G SFP+ uplinks, while CBS250-48T-4G has four 1G SFP uplinks. Both discontinued models connect 48 Gigabit copper endpoints without supplying PoE. CBS250-48T-4X fits existing 10G connections; CBS250-48T-4G fits like-for-like spare requirements where the installed uplinks remain 1G, rather than a new standard deployment.
C1200-48T-4X is the current Catalyst 1200 replacement for discontinued CBS250-48T-4X, rather than another Business 250 variant. The replacement retains 48 Gigabit access ports and four 10G SFP+ uplinks. CBS250-48T-4X fits an existing hardware spare requirement; C1200-48T-4X suits buyers establishing a current model standard without changing access density or uplink speed.
