CBS250-48T-4G-UK provides 48 Gigabit copper access ports and four fixed Gigabit SFP uplinks in a 1U rack-mount chassis. This Layer 2+ smart-managed switch connects independently powered Ethernet devices; its access ports do not supply PoE. Cisco Business 250 combines configurable switching with static routing for small-business networks that need more control than an unmanaged switch provides. The separate fiber uplinks leave the copper connections available for endpoint access, while the fixed uplink architecture requires no removable network card. The discontinued CBS250-48P-4G-UK differs by adding PoE+ for powered endpoints. This 48-port Gigabit access switch serves existing installations where Gigabit uplinks and individually managed switches remain the required configuration.

104 Gbps switching capacity supports nonblocking forwarding across the installed interfaces, while 77.38 Mpps forwarding capacity describes operation with 64-byte packets. Static IPv4 routing supports 32 routes and 16 IP interfaces, allowing manually configured communication between network segments. STP/RSTP/MSTP and LACP provide spanning-tree and link-aggregation controls without creating a hardware stack. CBS250-48T-4G-UK carries 512 MB of DRAM, 256 MB of flash and a shared 3 MB packet buffer. Browser configuration, command-line access and SNMP accommodate different administration workflows. Eight hardware queues support traffic prioritization, and access control lists support 512 rules for traffic filtering. 48.64W worst-case consumption at 220V gives a switch-only allowance for electrical planning; endpoint power must be supplied independently. A single cooling fan means this model is not fanless.
Order CBS250-48T-4G-UK from ORM Systems as new sealed with up to 3-year extended warranty, or certified refurbished with up to 1 year; 30-day returns apply to every condition, subject to terms. Refurbished units are inspected and bench-tested for rated-speed port links, optics bay recognition and clean boot, then firmware verified and wiped to factory default. Specify condition, quantities and MGBSX1 or MGBLX1 transceivers where needed; Cisco's limited lifetime hardware warranty remains subject to entitlement and ends October 31, 2029. For enterprise and volume purchasing, POs are accepted, government Net-30 is available, and regional stock and RMA with advance replacement cover the UK, EU, US and MEA.

When several small-business sites need a common management workflow, the embedded Cisco Business Dashboard probe runs on the switch without a separate on-site probe appliance or virtual machine. Include device discovery, administrator credentials and management addressing in the rollout specification before issuing the purchase order.
When a replacement must be staged before a maintenance window, dual firmware images retain an alternate image during an upgrade. The front-panel USB Type-A interface supports file and image handling. Specify the intended firmware, saved configuration and acceptance checks on the staging work order before shipment.
Power delivery to connected endpoints
All copper access ports are data-only, so connected devices need independent power. C1200-48P-4G provides a current 48-port PoE+ alternative with Gigabit SFP uplinks.
10G links to upstream switches
Fixed Gigabit SFP uplinks cannot provide 10G connections. C1200-48T-4X retains 48 Gigabit copper access ports and provides four 10G SFP+ uplinks.
One control plane across multiple switches
The Business 250 family has no hardware stacking capability. Separate switches remain individual devices even when viewed through a common management dashboard.

CBS250-48T-4G-UK identifies the Cisco Business 250 family, 48 non-PoE Gigabit copper ports, four Gigabit SFP uplinks and the UK regional ordering group. CBS250 identifies the family, 48T the access configuration, 4G the uplinks and UK the regional variant rather than a software license tier.
The Business 250 family supports a web UI over HTTP/HTTPS, CLI through the console or SSH/Telnet, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. Select the administration method before staging, and define the management address and access credentials required by the operating team.
CBS250-48T-4G-UK is discontinued: end of sale was October 29, 2024, and the last date of support is October 31, 2029. Software maintenance and scheduled vulnerability support ended October 29, 2025. C1200-48T-4G is the current replacement, not an extension of the older model's support period.
New sealed and certified refurbished CBS250-48T-4G-UK units have ORM coverage: up to 3-year extended warranty for new units and up to 1 year for refurbished units. Returns are accepted for 30 days on every condition; terms apply. Cisco's limited lifetime warranty is bounded by October 31, 2029, subject to entitlement.
No feature license or subscription is required for CBS250-48T-4G-UK; the hardware purchase includes its switch capabilities. There is no network-license tier or minimum subscription term to select. An order therefore needs the hardware condition and connection accessories, not a separate feature-unlock subscription.
CBS250-48T-4G-UK replaces the discontinued SG250-50-K9-UK and SF250-48-K9-UK. Their end-of-sale dates were October 30, 2021, and July 30, 2022, respectively. CBS250 is also discontinued, so these relationships identify legacy migrations rather than the current purchase option; C1200-48T-4G completes the replacement chain.
CBS250-48P-4G-UK supplies PoE+ from a shared 370W budget; CBS250-48T-4G-UK does not power endpoints. Both models are discontinued. The T model serves independently powered equipment, while the P model serves powered endpoints; new purchases needing endpoint power should use the current C1200-48P-4G replacement.
CBS250-48T-4G-UK has four 1G SFP uplinks, whereas CBS250-48T-4X-UK has four 10G SFP+ uplinks. Both models are discontinued. Existing Gigabit uplink installations may require the former; new purchases requiring faster upstream links should use the current C1200-48T-4X replacement for the latter.
C1200-48T-4G is the current successor to the discontinued CBS250-48T-4G-UK, rather than a higher-speed uplink variant. Both carry 48 Gigabit copper access ports and four Gigabit SFP uplinks. The older model serves matching-spare requirements; the successor suits new purchases that do not require the discontinued hardware.
Yes, CBS250-48T-4G-UK provides static IPv4 routing with 32 routes and 16 IP interfaces. These capabilities make the switch a Layer 2+ option for manually maintained inter-VLAN routes rather than a dynamic-routing edge. Count required routed interfaces and destinations before ordering because those limits are separate.
The Business 250 switch accepts MGBSX1 for multimode Gigabit fiber or MGBLX1 for single-mode Gigabit fiber. Transceivers are separate line items rather than included connection components. Match the selected transceiver, installed fiber and remote optical interface before specifying the final connection accessories for the purchase order.
CBS250-48T-4G-UK uses an internal AC supply accepting 100-240V AC and does not provide redundant internal power supplies. A power cord and mounting kit accompany the switch. Confirm the regional cord and mounting hardware against the condition selected for the order before arranging installation.
