CBS250-48P-4X-UK combines 48 Gigabit PoE+ access ports with four fixed 10G SFP+ uplinks in a Rack-Mount 1U chassis. The Business 250 smart switch provides Layer 2+ access switching for small-business networks connecting IP phones, wireless access points, cameras, and separately powered devices. Its copper connections handle endpoint traffic while dedicated fiber interfaces connect the access network upstream without an expansion card. Within the family, the discontinued CBS250-48T-4X-UK omits PoE, distinguishing the non-powered configuration from this powered-access model. The built-in SFP+ interfaces also support 1G operation, allowing uplink connections to match existing Gigabit fiber interfaces without replacing the switch or adding a network module.

176 Gbps switching capacity and 130.94 Mpps forwarding with 64-byte packets support wire-speed, nonblocking operation across the fixed configuration. 370W of shared PoE output requires sizing against simultaneous endpoint loads rather than assuming every connection can draw its per-port maximum together. Static routing accommodates 32 IPv4 routes and 16 IP interfaces for locally configured inter-VLAN paths. CBS250-48P-4X-UK carries 512 MB of DRAM and 256 MB of flash for runtime operation and image storage. A 3 MB packet buffer is dynamically shared across ports rather than assigned separately to each interface. The 8000-entry MAC table and 255-active-VLAN limit establish sizing boundaries for bridging and segmentation. Cisco Business 250 Series Smart Switches provide a web UI, CLI over SSH or Telnet, and SNMP for configuration and monitoring; Cisco Business Dashboard and the Cisco Business mobile app provide additional management paths. STP/RSTP/MSTP manage bridged topologies, while LACP aggregates links. Dynamic routing is not included.
Order CBS250-48P-4X-UK new sealed or certified refurbished, and specify the required condition, quantity, and regional accessories on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, PoE output under load on every powered port, optics bay recognition, clean boot, and PSU and fan status; firmware is verified and configuration is wiped to factory default. New units carry up to a 3-year extended ORM warranty, refurbished units up to 1 year, and both conditions have 30-day returns; terms apply. ORM Systems accepts enterprise and volume POs, provides Net-30 for government, and offers RMA with advance replacement; regional stock and RMA cover the UK, EU, US, and MEA.

A refresh from the discontinued SG250X-48P-K9-UK has CBS250-48P-4X-UK as its named migration model. Regional identification matters when standardizing replacement orders. Record the existing part number, the required regional version, and the unit condition on the PO before approving the hardware refresh.
A multi-site order needs a repeatable configuration process before units are distributed. Cisco Network Plug and Play supports PnP Connect, while text-editable configuration files can be downloaded to another switch. Define the shared configuration, site-specific settings, and onboarding method before specifying quantities and staging requirements on the PO.
A lab or staging order requiring traffic capture can mirror four source ports to one destination port. Dual firmware images support upgrade preparation, while USB Type-A provides local file and image handling. Specify the capture connections, firmware handoff, and acceptance checks before ordering the staging units.
Endpoints requiring more than 30W
PoE+ output is limited to 30W per powered port, so endpoints requiring higher input cannot receive their full power requirement from this model. Specify a different endpoint power arrangement.
Dynamic routing at the access edge
Routing is limited to static routes, with 32 IPv4 routes and 16 IP interfaces. Deployments requiring dynamically learned routes need a routing device with that capability rather than this smart switch.
Ongoing Cisco security fix availability
Vulnerability and security support ended October 29, 2025, excluding requirements for further fixes on this model. C1200-48P-4X is the current replacement with matching access-port count and uplink configuration.

CBS250-48P-4X-UK identifies a Cisco Business 250 smart switch: CBS250 names the family, 48 identifies the access-port count, P identifies PoE+, and 4X identifies four 10G SFP+ uplinks. UK is the regional ordering suffix for the United Kingdom and other supported markets; no license-tier suffix is present.
CBS250-48P-4X-UK is managed through its web UI, CLI over SSH or Telnet, RJ-45 console, SNMP, Cisco Business Dashboard, and Cisco Business mobile app. The web UI supports HTTP/HTTPS, configuration wizards, monitoring, and maintenance. An embedded Dashboard probe removes the need for a separate probe appliance.
Yes, CBS250-48P-4X-UK reached end of sale on October 29, 2024. Software maintenance and vulnerability support ended October 29, 2025, while the last date of support is October 31, 2029. C1200-48P-4X is the current migration model for buyers replacing this discontinued switch.
CBS250-48P-4X-UK is offered new sealed or certified refurbished, with ORM warranties of up to 3 years extended for new units and up to 1 year for refurbished units. Returns are available for 30 days in either condition; terms apply. Cisco's limited lifetime hardware warranty ends with Cisco support on October 31, 2029.
No, CBS250-48P-4X-UK requires no separate switch-feature license or subscription; all features accompany the hardware purchase. There are no network-license tiers or minimum subscription terms to select for this model. New sealed and ORM certified refurbished orders therefore do not need a switch-feature subscription line item.
CBS250-48P-4X-UK replaces SG250X-48P-K9-UK, which reached end of sale on October 30, 2021. The older model is discontinued, and the migration retains Gigabit PoE access with 10G uplinks. CBS250-48P-4X-UK has also been discontinued, so a new hardware refresh should follow the migration chain to C1200-48P-4X.
CBS250-48P-4X-UK provides a shared 370W PoE budget across 48 powered ports, with a 30W maximum per port. The aggregate budget prevents every port from delivering 30W simultaneously. Add the maximum simultaneous demands of phones, access points, and cameras before ordering; the per-port rating is not the whole-switch power allowance.
CBS250-48P-4X-UK supports SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber. SFP-10G-SR has a reach range of 26-400 m, while SFP-10G-LR reaches 10 km. Match the selected optic to fiber type, distance, and the remote interface, and include the transceivers on the PO.
Yes, Business 250 switches support static routing between VLANs, with 32 IPv4 static routes and 16 IP interfaces. VLAN, physical-port, link-aggregation, and loopback interfaces can carry routing configuration. This is static-routing access switching; dynamic route learning is not included, so upstream routing requirements must be specified separately.
CBS250-48P-4X-UK is a Rack-Mount 1U switch measuring 44 mm high, 445 mm wide, and 350 mm deep, with a weight of 5.43 kg. New units include a mounting kit and power cord. Specify rack space and confirm mounting accessories when ordering refurbished units.
No, CBS250-48P-4X-UK uses an internal AC supply without a redundant power-supply option. The universal input accepts 100-240V AC. Maximum consumption including PoE is 471.9W, so size the upstream electrical circuit and any backup power around total switch consumption rather than the endpoint power budget alone.
CBS250-48P-4X-UK provides PoE+ on its copper access ports, whereas CBS250-48T-4X-UK is non-PoE. Both models are discontinued. The powered version matches replacement-stock requirements for phones or access points receiving network power; the non-PoE version matches installations whose endpoints already have a separate power source.
CBS250-48P-4X-UK carries four 10G SFP+ uplinks, while CBS250-48P-4G-UK carries four 1G SFP uplinks. Both are discontinued Business 250 models. Retaining 10G distribution connections requires the 4X configuration; the 4G configuration matches replacement-stock requirements where the existing upstream fiber interfaces remain at Gigabit speed.
C1200-48P-4X is the current Catalyst 1200 migration model, while CBS250-48P-4X-UK is a discontinued Business 250 model. Both configurations carry 48 Gigabit PoE access ports and four 10G SFP+ uplinks. CBS250-48P-4X-UK serves installed-stock matching requirements; C1200-48P-4X is the replacement to specify for migration orders.
