CBS250-24T-4G-EU provides fanless Layer 2+ smart switching for small-business networks, combining 24 copper Gigabit Ethernet access ports with four fixed 1G SFP uplinks in a 1U rack-mount chassis. The non-PoE configuration connects separately powered desktops, printers and servers without supplying endpoint power. Cisco Business 250 Series switches support segmented workgroups and prioritized communications traffic within the same access network. The discontinued CBS250-24P-4G-EU adds PoE+ for powered endpoints, whereas this configuration keeps endpoint power outside the switch. Its uplinks are built in rather than supplied through a removable network card, making upstream speed a hardware selection rather than an expansion option. The combination serves existing Gigabit access installations requiring copper endpoint connections and fiber connections upstream.

56 Gbps switching capacity supports wire-speed, nonblocking forwarding across the installed interfaces. 41.66 Mpps forwarding with 64-byte packets establishes the small-packet throughput available for traffic sizing. Static IPv4 routing supports communication between local subnets within 32 routes and 16 IP interfaces; dynamic route learning is outside this configuration. A shared 1.5 MB packet buffer accommodates bursts across the ports rather than assigning a separate buffer to each interface. CBS250-24T-4G-EU carries 512 MB DRAM and 256 MB flash for its embedded software and configuration storage. STP/RSTP/MSTP address bridged loops, while LACP supports four aggregation groups with eight active ports per group. Access controls include RADIUS authentication, port security and time-based ACLs. Eight hardware queues support traffic scheduling, and IGMP snooping restricts multicast delivery to requesting receivers. Browser administration and CLI access support local configuration, while SNMP versions 1, 2c and 3 provide monitoring access.
Order CBS250-24T-4G-EU new sealed or certified refurbished, specifying quantity, condition and destination on the purchase order. Certified refurbished units are inspected and bench-tested, including rated-speed links on every port and optics bay recognition, with firmware verified and configuration wiped to factory default. New units carry up to a 3-year extended ORM warranty and certified refurbished units up to 1 year; every condition includes 30-day returns, terms apply, while Cisco's separate limited lifetime hardware coverage cannot extend beyond October 31, 2029. Enterprise and volume orders support POs, Net-30 for government, RMA with advance replacement and regional stock/RMA coverage across the UK, EU, US and MEA.

When a branch rollout includes European Economic Area locations, the EU regional order code ties hardware selection to the intended destination. The same suffix also covers Switzerland and Turkey. Specify destination countries and confirm the supplied power cord before the purchase order is released.
When several switches are staged before shipment, text-editable configuration files let technicians prepare a common configuration and download it to each unit. SCP protects configuration transfers, while dual firmware images support upgrade preparation. Specify the staging image, configuration file and transfer credentials before releasing the purchase order.
When separate offices need a common management view, the embedded Cisco Business Dashboard probe removes the requirement for a separate probe computer or virtual machine at each location. The Cisco Business mobile app also supports local setup. Identify the Dashboard host, site inventory and administrator access before ordering.
10G uplinks to distribution
The fixed uplinks stop at 1G and cannot accept an uplink expansion card. C1200-24T-4X is the current migration option with four 10G SFP+ uplinks.

CBS250-24T-4G-EU identifies a Cisco Business 250 switch: CBS250 is the series, 24 denotes the copper access-port count, T denotes the non-PoE Gigabit configuration, and 4G denotes four Gigabit SFP uplinks. EU is the regional suffix covering the European Economic Area and other designated markets, not a software license tier.
Cisco Business 250 switches support an HTTP/HTTPS web interface, CLI over SSH or Telnet, RJ-45 console, Cisco Business Dashboard, Cisco Business mobile app and SNMP versions 1, 2c and 3. Browser wizards support initial configuration, while the CLI provides scriptable administration. Network Plug and Play handles provisioning.
CBS250-24T-4G-EU is discontinued: end of sale was October 29, 2024, and software maintenance plus vulnerability/security support ended October 29, 2025. The last date of applicable Cisco support is October 31, 2029. C1200-24T-4G is the current migration model for a new purchase requiring a successor.
ORM offers CBS250-24T-4G-EU new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Both conditions include 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty cannot extend beyond October 31, 2029; eligibility remains subject to its terms.
CBS250-24T-4G-EU replaced the discontinued SG250-26-K9-EU, SG250-26-K9-KR and SF250-24-K9-EU. The two SG250 predecessors reached end of sale on October 30, 2021; SF250-24-K9-EU followed on July 30, 2022. These are historical migration relationships, not current purchase recommendations, because the CBS250 model is also discontinued.
GLC-SX-MMD and GLC-LH-SMD are compatible Gigabit fiber transceivers for CBS250-24T-4G-EU, serving multimode links to 550 m and single-mode links to 10 km respectively. The four fixed SFP uplinks operate at 1G. Match fiber type, connector arrangement and the remote-end optical specification before adding transceivers to the order.
CBS250-24T-4G-EU supports static IPv4 routing with 32 static routes and 16 IP interfaces, placing this configuration in the Layer 2+ category. Local VLANs can exchange traffic without sending every packet through an external router. Plan routes and interfaces within those limits rather than expecting dynamic route learning.
CBS250-24T-4G-EU uses a fixed internal AC supply accepting 100-240V AC at 50-60 Hz, without a redundant PSU option. Worst-case system consumption is 25.91W at 110V and 25.63W at 220V. Endpoint power must come from separate sources because this configuration supplies no PoE.
CBS250-24P-4G-EU supplies PoE+ through its 24 access ports with a shared 195W budget, while CBS250-24T-4G-EU supplies no endpoint power. Both models are discontinued. The T model fits separately powered equipment; the P model fits existing powered-endpoint installations where the allocated load remains within the shared budget.
CBS250-24T-4X-EU has four 10G SFP+ uplinks, whereas CBS250-24T-4G-EU has four 1G SFP uplinks. Both discontinued models retain Gigabit copper access ports. The 4X version addresses higher upstream link-speed requirements in existing installations; the 4G version matches installations retaining Gigabit fiber uplinks.
C1200-24T-4G is the current migration replacement for discontinued CBS250-24T-4G-EU, retaining 24 Gigabit copper ports and four Gigabit SFP uplinks. The distinction is product generation and lifecycle position rather than port speed. Existing fleets may require the CBS250 model; new standardization purchases should assess the replacement.
Cisco Business 250 model CBS250-24T-4G-EU provides 56 Gbps switching capacity and 41.66 Mpps forwarding with 64-byte packets. The switching architecture is wire-speed and nonblocking, and a shared 1.5 MB packet buffer serves the ports. Use packet rate and burst behavior alongside link speeds when sizing traffic.
Cisco Business 250 supports text-editable configurations, SCP configuration downloads, dual firmware images and a Cisco Network Plug and Play agent. These functions support configuration staging and repeatable provisioning while retaining device-specific network settings. Define the approved firmware image, configuration template and secure-transfer credentials before preparing multiple units.
Cisco Business 250 supports STP/RSTP/MSTP, LACP, RADIUS authentication, port security and time-based ACLs. LACP permits four aggregation groups with eight active ports per group. Eight hardware queues support traffic scheduling, while IGMP snooping restricts multicast delivery to interested receivers. Match the planned aggregation and security configuration to these limits.
CBS250-24T-4G-EU fits a 1U rack position, measuring 445 mm wide, 240 mm deep and 44 mm high. Unit weight is 2.63 kg, and operating temperature is -5°C to 50°C. The fanless chassis includes mounting hardware; verify rack clearance and ambient temperature before allocating its installation position.
