CBS250-48PP-4G-UK is a Layer 2+ smart-managed access switch with 48 Gigabit Ethernet PoE+ ports and four fixed 1G SFP uplinks. Its rack-mount 1U chassis places copper endpoint connections and fiber uplinks in one unit, without requiring a separate uplink card. The Cisco Business 250 Series serves small-business networks connecting computers, IP phones, wireless access points, and surveillance cameras. Powered and independently powered devices can share the access ports, with endpoint power allocated within the switch's total allowance. The discontinued CBS250-48P-4G-UK offers a larger PoE budget for installations retaining the same copper-port density. This 48-port Gigabit PoE+ smart switch provides static inter-VLAN routing rather than an enterprise dynamic-routing feature set.

104 Gbps switching capacity supports simultaneous traffic across the access and uplink interfaces, while 77.38 Mpps forwarding capacity defines packet-processing performance. 195W of shared PoE power requires allocation across connected devices rather than reserving maximum output for every powered port. Static IPv4 routing supports 32 routes and 16 IP interfaces for communication between local subnets. CBS250-48PP-4G-UK carries 512 MB of DRAM and 256 MB of flash for operating software and configuration storage. A dynamically shared 3 MB packet buffer serves traffic across the ports. STP/RSTP/MSTP and LACP support loop control and aggregated connections; hardware stacking is not supported. Management choices include the browser interface, CLI, SNMP, Cisco Business Dashboard, and Cisco Business mobile app. The embedded Dashboard probe avoids a separate on-site probe appliance.
Order CBS250-48PP-4G-UK new sealed or certified refurbished: new units carry up to a 3-year extended warranty, refurbished units up to 1 year, with 30-day returns on every condition, terms apply. Certified refurbished units are inspected and bench-tested, including PoE output under load on every powered port, optics bay recognition, firmware verification, and configuration wiped to factory default. Specify condition and quantity on the PO; Cisco's separate limited lifetime warranty is bounded by October 31, 2029. Enterprise and volume purchasing includes PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock and RMA across the UK, EU, US, and MEA.

When replacing discontinued SG250-50HP-K9-UK or SF250-48HP-K9-UK equipment, the regional successor relationship provides a starting point for an existing-fleet purchase. Retaining a replacement relationship does not make saved configurations interchangeable. Review the endpoint inventory, configuration requirements, and remaining service horizon before specifying condition and quantity on the PO.
When adding phones, cameras, or wireless access points, the 30W per-port ceiling is not an allowance available simultaneously at every connection. Build an endpoint power schedule using each device's required draw, including startup requirements, then check the combined load against the shared power allowance before ordering.
When preparing switches for several locations, editable configuration files and secure SCP transfers support a repeatable staging process. CLI privilege levels 1, 7, and 15 allow different administrative access levels. Define the site-specific settings, administrator roles, and configuration-transfer procedure before specifying the rollout quantities on the PO.
10G uplinks to distribution
CBS250-48PP-4G-UK has fixed 1G SFP uplinks and no removable uplink-card bay. A requirement for native 10G uplinks exceeds this model's connection capability.
Hardware stacking for unified control
Cisco Business 250 switches do not support hardware stacking. Centralized dashboard management does not turn separate switches into members of a hardware stack.
Ongoing security software fixes
CBS250-48PP-4G-UK vulnerability and security support ended October 29, 2025. A deployment requiring continuing manufacturer security remedies falls outside this model's remaining support coverage.

CBS250-48PP-4G-UK identifies a Cisco Business 250 smart switch: 48 denotes the copper-port count, PP denotes Partial PoE, 4G denotes four Gigabit SFP uplinks, and UK is a regional ordering suffix. Partial PoE describes the available power allowance, not a reduction in the number of PoE-capable access ports.
Cisco Business 250 switches support a web interface over HTTP/HTTPS, CLI through the console or SSH/Telnet, SNMP, Cisco Business Dashboard, and Cisco Business mobile app. An embedded Dashboard probe removes the need for a separate probe appliance. Select the administrative access methods and credentials during configuration staging.
CBS250-48PP-4G-UK provides a shared 195W PoE budget across 48 PoE-capable ports, with a maximum of 30W at an individual port. The total allowance cannot supply every port at its individual maximum simultaneously. Sum the required power of the intended endpoints before committing the port allocation.
CBS250-48PP-4G-UK has four fixed 1G SFP uplinks; MGBSX1 supports multimode fiber to 500 m, and MGBLX1 supports single-mode fiber to 10 km. These are transceivers for the built-in cages, not uplink expansion cards. Match the selected transceiver to the installed fiber and the equipment at the opposite end.
Cisco Business 250 switches require no separate feature license or mandatory software subscription for their included switching functions. The hardware purchase includes the available feature set, without a minimum subscription term. Keep switch operation separate from any optional management or service purchases when reviewing the proposed order.
CBS250-48PP-4G-UK is discontinued, with an end-of-sale date of October 29, 2024, and a last support date of October 31, 2029. Software maintenance and vulnerability support ended October 29, 2025. No migration product is assigned to this exact model, so its remaining hardware-support period should not be mistaken for continuing software fixes.
CBS250-48PP-4G-UK replaces the discontinued SG250-50HP-K9-UK and SF250-48HP-K9-UK. Their end-of-sale dates were October 30, 2021, and July 30, 2022, respectively. The successor is also discontinued, so an existing-fleet replacement purchase needs its own assessment of remaining support, configuration requirements, and endpoint power demand.
CBS250-48PP-4G-UK provides a 195W PoE budget, while CBS250-48P-4G-UK provides 370W. Both models are discontinued. For an existing-fleet purchase, the first suits an endpoint schedule within the lower allowance; the second accommodates a larger combined powered-device load without changing the access-port count.
CBS250-48PP-4G-UK has four 1G SFP uplinks, while CBS250-48P-4X-UK has four 10G SFP+ uplinks. Both models are discontinued. In an existing installation, the first matches Gigabit uplink connections; the second addresses a requirement for native 10G uplinks, subject to selecting the corresponding connection equipment.
CBS250-48PP-4G-UK provides 48 copper access ports, while CBS250-24PP-4G-UK provides 24. Both models are discontinued. Buyers maintaining an existing installation can distinguish them by the number of endpoint connections required: the first serves the larger connection inventory, while the second matches a smaller access-port requirement.
ORM Systems offers CBS250-48PP-4G-UK new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Returns cover 30 days on every condition; terms apply. Cisco's separate limited lifetime hardware warranty is bounded by the last support date of October 31, 2029.
