CBS250-24PP-4G-UK combines fanless cooling with 24 Gigabit Ethernet PoE+ access ports and four fixed 1G SFP uplinks in a rack-mount 1U chassis. The smart-managed Layer 2+ switch connects computers, IP phones, and wireless access points in small-business networks, with static routing available for communication between local subnets. The Cisco Business 250 Series keeps dedicated fiber uplinks separate from copper endpoint connections. Partial PoE describes the shared power allocation, not a restriction to selected access ports. The discontinued CBS250-24P-4G-UK carries a larger 195W PoE budget for comparison. This 24-port Gigabit PoE+ switch retains fixed uplink architecture rather than providing an expansion bay for a removable network module.

56 Gbps switching capacity supports nonblocking forwarding across the installed interfaces. 41.66 Mpps forwarding handles 64-byte packets at wire speed. 100W of shared PoE capacity powers connected endpoints within a 30W per-port ceiling, so aggregate demand must remain inside the available allocation. 32 static IPv4 routes support local subnet forwarding without dynamic route learning. CBS250-24PP-4G-UK carries 512 MB of DRAM and 256 MB of flash for runtime operation and local image storage. An 800 MHz ARM processor handles control functions, while a 1.5 MB packet buffer is dynamically shared across ports. STP, RSTP, and MSTP control Layer 2 loops; LACP supports link aggregation. The switch supports 255 active VLANs, voice VLAN handling, and eight hardware queues for traffic prioritization. Browser management, CLI access, and SNMP provide administration paths. Hardware stacking is not supported, and dashboard management does not turn separate switches into a hardware stack.
ORM Systems offers CBS250-24PP-4G-UK new sealed or certified refurbished; refurbished units are inspected and bench-tested, including PoE output under load on every powered port, optics bay recognition, firmware verification, and a factory-default configuration wipe. Specify condition, regional version, optics, and quantity on the PO; ORM warranties are up to a 3-year extended warranty for new units and up to 1 year for refurbished units, with 30-day returns on every condition, terms apply. Cisco's limited lifetime hardware warranty ends with Cisco service on October 31, 2029. Enterprise and volume orders have PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA in the UK, EU, US, and MEA.

When a small office needs traffic forwarded between local subnets, the switch supports 16 IP interfaces using physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. That interface limit is separate from endpoint count. Map the required routed interfaces and addressing before specifying the configuration on the purchase order.
When repeat branch deployments require a common configuration, the embedded Cisco Network Plug and Play agent supports Cisco PnP Connect, while text-editable configuration files can be downloaded to another switch. Define the provisioning method, configuration owner, and site-specific addressing before specifying rollout quantities on the purchase order.
When equipment must be staged before shipment, the front-panel USB Type-A slot supports file and image handling, and dual firmware images support upgrade preparation. Keep the approved image and site configuration separate from the hardware purchase specification, and confirm the required staging procedure and condition before issuing the order.
10G links to distribution
The four fixed SFP uplinks operate at 1G and cannot provide a 10G distribution connection. Adding a removable network module cannot raise their speed.
Endpoints requiring more than 30W
PoE+ output stops at 30W per powered port, so an endpoint requiring more than 30W cannot receive its full rated input from this switch.
More than 32 static routes
IPv4 routing supports 32 static routes and 16 IP interfaces. A design exceeding either limit requires different routing hardware rather than an additional operating license.

CBS250-24PP-4G-UK identifies a Cisco Business 250 smart switch: 24 denotes the Gigabit access-port count, PP indicates Partial PoE, and 4G denotes four Gigabit SFP uplinks. UK is the regional ordering suffix for the United Kingdom and several other markets, not a software license tier or a different port configuration.
The Cisco Business 250 Series supports a web UI over HTTP/HTTPS, CLI over SSH/Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. CBS250-24PP-4G-UK also has an RJ-45 console for local CLI access. An embedded dashboard probe and Cisco Network Plug and Play provide additional management and provisioning paths.
No license or subscription is required to operate CBS250-24PP-4G-UK, so there is no mandatory minimum subscription term for switch operation. The UK suffix selects a regional hardware ordering version rather than an enterprise software tier. Specify the required hardware condition and accessories without adding an operating-subscription requirement.
100W is the shared PoE budget for CBS250-24PP-4G-UK, and all 24 copper access ports support PoE+ with a 30W per-port ceiling. Partial PoE describes limited total power, not a restriction to selected ports. Add endpoint requirements before deployment because power availability depends on combined load, not simply the number of connected devices.
Four fixed 1G SFP uplinks connect CBS250-24PP-4G-UK to compatible fiber links; they do not provide 10G operation. MGBSX1 supports multimode fiber to 500 m, while MGBLX1 supports single-mode fiber to 10 km. Specify the selected transceiver separately to match the installed fiber type and each link's required reach.
Yes, the Cisco Business 250 Series supports inter-VLAN forwarding with 32 static IPv4 routes and 16 IP interfaces. Static routing makes this a Layer 2+ switch under the catalog's routing categories. Plan routed interfaces separately from the 255 active VLAN limit; VLAN capacity does not mean every VLAN can have a routed interface.
Yes, CBS250-24PP-4G-UK is discontinued: end of sale was October 29, 2024, and the last date of support is October 31, 2029. Software maintenance and vulnerability/security support ended October 29, 2025. No direct migration product is available for this model, and remaining hardware support does not mean continuing security fixes.
CBS250-24PP-4G-UK replaces the discontinued SG250-26HP-K9-UK, whose end-of-sale date was October 30, 2021. The replacement configuration provides 24 Gigabit access ports with Partial PoE and four 1G SFP uplinks. CBS250-24PP-4G-UK is also discontinued, so this is a historical migration relationship rather than a current-generation purchasing recommendation.
CBS250-24P-4G-UK provides a 195W PoE budget, compared with 100W on CBS250-24PP-4G-UK. Both models are discontinued. The former addresses a larger combined endpoint power requirement, while the latter fits a lower aggregate PoE allocation where an existing configuration is being retained or supported with matching spare hardware.
CBS250-24P-4X-UK has four 10G SFP+ uplinks, whereas CBS250-24PP-4G-UK has four 1G SFP uplinks. Both are discontinued. The 10G version addresses higher-speed distribution connections; the 1G version suits retained Gigabit fiber links. Compare the required link speed at both ends before choosing between remaining hardware inventories.
CBS250-48PP-4G-UK supplies 48 Gigabit access ports, while CBS250-24PP-4G-UK supplies 24. Both models are discontinued. The higher-port-count model addresses more copper endpoints at one location; the 24-port version suits smaller cabling counts. Size physical connection requirements first, then assess endpoint power allocation as a separate purchasing decision.
Yes, CBS250-24PP-4G-UK uses a full-width rack-mount 1U chassis with fanless cooling. The enclosure measures 445 mm wide, 299 mm deep, and 44 mm high, with a unit weight of 3.53 kg. A mounting kit accompanies the device; confirm the required mounting hardware with the selected condition before installation.
No, CBS250-24PP-4G-UK uses a fixed internal AC supply rather than redundant PSU modules. Input is 100-240V AC at 50-60 Hz. Maximum consumption with PoE load is 138.9W at 110V AC or 138.1W at 220V AC, so electrical sizing must include the whole switch rather than only its endpoint power budget.
ORM Systems offers CBS250-24PP-4G-UK new sealed with up to a 3-year extended ORM warranty or certified refurbished with up to 1 year. Every condition has 30-day returns, terms apply. Cisco's separate limited lifetime hardware warranty ends with Cisco service on October 31, 2029; software maintenance and security support ended October 29, 2025.
