CBS250-48T-4X-UK is a smart-managed Layer 2+ access switch with 48 Gigabit Ethernet copper ports and four fixed 10G SFP+ uplinks. The non-PoE configuration connects computers, printers, servers, and separately powered network devices in a 1U rack-mounted chassis. Cisco Business 250 Series switching combines VLAN segmentation with local inter-VLAN communication for small-business networks. The uplink connections are separate from the copper access ports, so distribution connections do not consume endpoint connections. The discontinued CBS250-48P-4X-UK differs by providing PoE+ for powered endpoints. Browser-based administration and command-line access let operators configure the network locally, while centralized management is available for installations managed across multiple locations. This is an access switch for Gigabit endpoints, not a multigigabit copper access model.

176 Gbps switching capacity provides nonblocking forwarding across the access and uplink connections, while 130.94 Mpps forwarding handles minimum-size Ethernet packets. Static IPv4 routing supports 32 routes for manually configured paths between networks. STP, RSTP, and MSTP provide loop-control options, and LACP combines compatible connections into link aggregation groups. CBS250-48T-4X-UK has 512 MB DRAM and 256 MB flash for its operating software and configuration storage. A shared 3 MB packet buffer accommodates traffic arriving across the ports. Eight hardware queues support traffic prioritization, with strict-priority and weighted scheduling available for different traffic classes. The Cisco Business management interface also supports SNMP monitoring, and an RJ-45 console connection provides local administrative access. Hardware stacking is not supported: centralized visibility does not turn multiple switches into a shared forwarding system. A maximum system draw of 51.01W provides the figure to use when allocating mains and backup-power capacity.
New sealed and certified refurbished CBS250-48T-4X-UK units carry ORM coverage of up to a 3-year extended warranty and up to 1 year respectively, plus 30-day returns on every condition, terms apply. Cisco's limited lifetime hardware warranty remains subject to eligibility, with Cisco service ending October 31, 2029. Certified refurbished units are inspected and bench-tested, with optics bay recognition, firmware verified, and configuration wiped to factory default; specify this switch's condition, quantity, and required accessories on the PO. ORM accepts POs, offers Net-30 for government and RMA with advance replacement, and handles regional stock and RMA across the UK, EU, US, and MEA.

When separate workgroups need communication between their network segments, the Business 250 series supports 16 IP interfaces. Interfaces can be associated with physical ports, link aggregation groups, VLANs, or loopback interfaces. Map the required segments and interface assignments before specifying the switch on the purchase order.
When several locations need a consistent provisioning process, Cisco Network Plug and Play supports device onboarding, and an embedded Cisco Business Dashboard probe avoids a separate probe appliance at each site. Identify the provisioning service, administrator access, and site-specific configuration requirements before ordering the rollout quantities.
When switches must pass through staging before shipment to their installation sites, dual firmware images support controlled software changes. Configuration files can be edited and transferred between switches, with SCP available for protected file transfer. Specify the required firmware acceptance checks and configuration handover requirements before issuing the PO.
PoE power for connected endpoints
CBS250-48T-4X-UK supplies no endpoint power. C1200-48P-4X is the current PoE-enabled alternative with 48 Gigabit access ports and four 10G SFP+ uplinks.
More than 32 IPv4 routes
CBS250-48T-4X-UK supports 32 static IPv4 routes. Networks requiring a larger routing table exceed this limit; purchasing an additional software license does not expand it.
Fanless operation in occupied rooms
CBS250-48T-4X-UK uses one fan, with acoustic output of 29.7 dBA at 25°C. Installations requiring a fanless chassis cannot use this model.

CBS250-48T-4X-UK identifies a Business 250 smart switch: 48T denotes 48 non-PoE Gigabit copper ports, and 4X denotes four 10G SFP+ uplinks. UK is a regional ordering suffix covering the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong, and Malaysia; it is not a software license tier.
CBS250-48T-4X-UK supports a browser interface over HTTP or HTTPS, CLI access through its RJ-45 console or SSH and Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. The CLI supports both full command entry and menu-based operation, allowing local administration alongside centralized monitoring.
CBS250-48T-4X-UK reached end of sale on October 29, 2024, and software maintenance and vulnerability support ended October 29, 2025. The last date of eligible Cisco hardware support is October 31, 2029. C1200-48T-4X is the current replacement for buyers moving beyond the discontinued model.
ORM offers CBS250-48T-4X-UK new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Every condition has 30-day returns, terms apply. Cisco's limited lifetime hardware warranty is separate, subject to eligibility, and bounded by October 31, 2029, when Cisco service ends.
The Business 250 series requires no separate software license or subscription for its included switch features. All switching functionality comes with the hardware purchase, so there are no feature-tier names or minimum subscription terms to select. Hardware procurement does not require adding a recurring switching license.
CBS250-48T-4X-UK replaces SG250X-48-K9-UK, which reached end of sale on October 30, 2021. Both provide 48 Gigabit access connections with 10G uplinks. The older model is discontinued, and the Business 250 replacement is now also discontinued; the current forward migration ends at C1200-48T-4X.
CBS250-48T-4X-UK supports SFP-10G-SR for multimode fiber, SFP-10G-LR for single-mode fiber, and SFP-H10GB-CU1M for a 1 m direct-attach connection. Its SFP+ interfaces support both 10G and 1G operation. Select the accessory for the fiber type, link distance, and compatible interface at the other end.
CBS250-48T-4X-UK is a rack-mounted 1U switch measuring 445 mm wide, 288 mm deep, and 44 mm high, with a weight of 3.95 kg. A mounting kit is included with the original package. Check rack space, cable clearance, and the accessories supplied with the selected condition before ordering.
The Business 250 series provides static routing, supporting 32 IPv4 static routes and 16 IP interfaces. Interfaces can use physical ports, link aggregation groups, VLANs, or loopbacks. This is Layer 2+ functionality rather than dynamic routing, so route changes require configuration rather than automatic route exchange.
No, CBS250-48T-4X-UK cannot form a hardware stack with other switches. Cisco Business Dashboard can provide centralized management, but that does not create a shared switching control plane or cross-stack forwarding system. Plan each unit as a separate switch with its own network connections and configuration.
CBS250-48T-4X-UK has non-PoE access ports, while CBS250-48P-4X-UK provides PoE+ with a shared 370W power budget. Both models are discontinued. The non-PoE version serves existing installations with separately powered endpoints; the PoE+ version serves retained Business 250 installations that need power delivered over Ethernet.
CBS250-48T-4X-UK has four 10G SFP+ uplinks, whereas CBS250-48T-4G-UK has four 1G SFP uplinks. Both are discontinued non-PoE models with 48 Gigabit copper access ports. The 4X version suits an existing installation requiring 10G distribution connections; the 4G version suits retained infrastructure limited to 1G uplinks.
C1200-48T-4X is the current replacement for CBS250-48T-4X-UK, which reached end of sale on October 29, 2024. Both offer 48 Gigabit copper access ports and four 10G SFP+ uplinks. The Business 250 model serves existing-estate requirements; the Catalyst 1200 model is the forward migration choice.
