Fanless Access Connectivity for Small Business Networks

CBS250-24P-4X-UK delivers fanless, smart-managed Layer 2+ switching through 24 Gigabit RJ-45 PoE+ access ports and four fixed 10G SFP+ uplinks. The Rack-Mount 1U chassis belongs to the Cisco Business 250 series and connects computers while supplying power to compatible phones, wireless access points and cameras. Its fixed uplink architecture does not require a removable network module. The Cisco Business portfolio combines local configuration with centralized management options for small-business networks. Voice VLAN and traffic prioritization separate delay-sensitive communications from other application traffic, while access controls govern endpoint connectivity. The discontinued CBS250-24FP-4X-UK differs with a 370W PoE budget, making aggregate endpoint power demand the principal distinction between these two configurations.

Technical Details

128 Gbps switching capacity supports a nonblocking forwarding fabric. 95.23 Mpps forwarding applies to 64-byte packets, providing a defined basis for traffic-profile comparisons. 195W of shared PoE capacity must be allocated across connected powered devices rather than treated as a full-power allowance for every port. Static IPv4 routing supports 32 routes and 16 IP interfaces; dynamic routing is not supported. CBS250-24P-4X-UK combines 512 MB of DRAM with 256 MB of flash for operation and image storage. A dynamically shared 1.5 MB packet buffer serves the entire switch, while the MAC table accommodates 8000 addresses and VLAN configuration supports 255 active VLANs. STP/RSTP/MSTP provide spanning-tree controls, and LACP supports four aggregation groups with eight ports per group. SNMP versions 1, 2c and 3 provide monitoring integration. 240.4W maximum consumption, including PoE load, supplies the upper power figure for sizing the supporting electrical circuit.

Ordering

Specify CBS250-24P-4X-UK, the required quantity and either new sealed or certified refurbished condition on the purchase order. Refurbished units are inspected and bench-tested, with every port linked at rated speed, PoE output verified under load on every powered port, firmware verified and configuration wiped to factory default. New units carry up to 3-year extended warranty and certified refurbished units up to 1 year; returns are 30 days on every condition, terms apply, while Cisco's separate limited lifetime warranty is bounded by its October 31, 2029 service end date. For enterprise and volume orders, ORM Systems accepts POs, offers Net-30 for government, and provides RMA with advance replacement across UK, EU, US and MEA regions.

Buying Notes

Buying NotesKey Specs

Software support has ended

CBS250-24P-4X-UK requires migration planning because software maintenance and vulnerability support ended October 29, 2025. C1200-24P-4X is the current replacement; remaining hardware support does not extend those software milestones.

Specify uplink media separately

CBS250-24P-4X-UK orders need matching uplink media: SFP-10G-SR for multimode fiber, SFP-10G-LR for single-mode fiber, or SFP-H10GB-CU3M for a 3 m copper connection. Match the selection to the remote interface.

Best For

Legacy Hardware Refresh

When retiring the discontinued SG250X-24P-K9-UK, which reached end of sale on October 30, 2021, an existing equipment standard may identify this switch as the replacement. Review the saved configuration and connected equipment before committing to another generation. Specify the required condition, replacement quantity and acceptance checks on the purchase order.

Multi-Site Management Standardization

When several sites standardize their management approach, the embedded Cisco Business Dashboard probe removes the need for a separate probe appliance or virtual machine. Management ownership still needs to be assigned per location. Specify the dashboard environment, administrative access requirements and site configuration responsibilities before issuing the purchase order.

Lab And Staging

Before a staged cutover, dual firmware images provide separate image storage for preparing the intended firmware revision. Browser-based firmware transfers and TFTP upgrades support different staging workflows. Preserve the existing configuration, identify the intended image and define the boot verification sequence. Include staging responsibilities and acceptance requirements with the equipment order.

Not Suitable If

30W on every powered port

The shared 195W budget cannot supply 30W simultaneously across all 24 powered ports. C1200-24FP-4X is the current full-PoE alternative, but its shared budget also requires endpoint sizing.

Dynamic routing at the access edge

CBS250-24P-4X-UK supports static routing rather than dynamic routing, with 32 IPv4 routes and 16 IP interfaces. Designs requiring automatic route learning exceed these capabilities.

New Cisco security fixes during deployment

Cisco vulnerability and security support ended October 29, 2025. C1200-24P-4X is the current replacement for orders requiring a series with ongoing firmware releases.

Questions & Answers

What does the CBS250-24P-4X-UK part number mean?

CBS250-24P-4X-UK identifies a Business 250 switch with 24 Gigabit PoE+ ports and four 10G SFP+ uplinks. CBS250 identifies the series, 24 identifies the access-port count, P identifies the PoE configuration, and 4X identifies the uplinks. UK is the regional suffix covering the United Kingdom and specified additional markets.

How is CBS250-24P-4X-UK managed?

CBS250-24P-4X-UK supports a browser-based HTTP/HTTPS interface, CLI access through its console or SSH/Telnet, Cisco Business Dashboard and the Cisco Business mobile app. SNMP versions 1, 2c and 3 provide additional monitoring integration. The CLI supports both scriptable commands and a menu-based interface for administrative workflows.

How much PoE power does CBS250-24P-4X-UK provide?

CBS250-24P-4X-UK provides a shared 195W PoE budget across 24 powered ports, with PoE+ supporting 30W per port. The aggregate budget does not permit every powered port to deliver its individual maximum simultaneously. Size the connected endpoint load before ordering, including the requirements of phones, access points and cameras.

Which uplink optics work with CBS250-24P-4X-UK?

CBS250-24P-4X-UK supports SFP-10G-SR for multimode fiber and SFP-10G-LR for single-mode fiber, together with SFP-H10GB-CU3M for a 3 m copper connection. These choices serve different media and distance requirements. Select uplink media against the installed cabling, link distance and compatible interface at the opposite end.

Can the Business 250 switch route between VLANs?

The Business 250 supports static IPv4 routing between configured interfaces, with 32 static routes and 16 IP interfaces. Its routing capability places this configuration in Layer 2+ rather than a dynamic-routing category. Routing interfaces can be associated with physical ports, aggregation groups, VLAN interfaces or loopback interfaces.

What power supply does CBS250-24P-4X-UK use?

CBS250-24P-4X-UK uses an internal AC power supply accepting 100-240V AC, rather than an external power adapter. The chassis does not provide internal redundant power supplies. Maximum consumption including PoE load is 240.4W, so electrical sizing must include endpoint power rather than considering switch electronics alone.

Which older switch does CBS250-24P-4X-UK replace?

CBS250-24P-4X-UK replaces the discontinued SG250X-24P-K9-UK, whose end-of-sale date was October 30, 2021. That predecessor's last support date is October 31, 2026. CBS250-24P-4X-UK has subsequently also reached end of sale, and C1200-24P-4X is the current endpoint of this replacement chain for new-generation purchasing.

Is CBS250-24P-4X-UK end of sale?

Yes, CBS250-24P-4X-UK reached end of sale on October 29, 2024, with the last support date set for October 31, 2029. Software maintenance and vulnerability support ended October 29, 2025. C1200-24P-4X is the current replacement; the remaining hardware support period does not imply continued security fixes.
