CBS350-48FP-4G-UK combines 48 Gigabit Ethernet PoE+ access ports with four fixed 1G SFP uplinks in a managed Layer 2+ rack-mount switch. The 1U chassis belongs to the Cisco Business 350 family and connects workstations alongside powered IP phones, wireless access points and surveillance endpoints in small-business networks. Dedicated SFP uplinks leave the copper access connections available for endpoints, while the fixed architecture means the uplink speed cannot be changed by adding a network module. The discontinued CBS350-48P-4G-UK lowers the PoE allocation to 370W for installations with a smaller aggregate powered-device load. This 48-port Gigabit PoE+ access switch uses an internal AC supply rather than a separate desktop adapter, so the purchase does not require an external power adapter.

104 Gbps switching capacity accommodates nonblocking traffic across the installed ports, and 77.38 Mpps forwarding performance applies to 64-byte packets. 740W of shared PoE power must be allocated against combined endpoint demand rather than assumed to provide unrestricted power on every connection. Static routing, RIP v2 and PBR handle local traffic decisions within the small-business feature set. CBS350-48FP-4G-UK combines 512 MB of DRAM with 256 MB of flash for its embedded software, while its 3 MB packet buffer is shared dynamically across all ports. STP, RSTP, MSTP and LACP support loop control and aggregated links; hardware stacking is not supported. Administrators can use the web interface or Textview CLI for local configuration. A single fan provides active cooling, and the -5°C to 50°C operating range sets the equipment-room temperature limits. 886.42W maximum consumption with PoE is the figure to use when planning upstream electrical capacity.
ORM Systems supplies CBS350-48FP-4G-UK new sealed or certified refurbished; refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified and configurations wiped to factory default. Specify the required condition, unit quantities and delivery region on the purchase order before order release. New units carry up to a 3-year extended ORM warranty and certified refurbished units up to 1 year, with 30-day returns on every condition; terms apply. For enterprise and volume orders, POs are accepted, government buyers can use Net-30, and RMA with advance replacement is available through UK, EU, US and MEA regional stock/RMA operations.

When a purchase replaces discontinued SG350-52MP-K9-UK or SF350-48MP-K9-UK hardware, CBS350-48FP-4G-UK is a migration option for both. Their end-of-sale dates were October 30, 2021 and July 30, 2022, respectively. Compare the existing configuration and endpoint requirements before specifying the replacement quantity on the PO.
When several branches need the same initial configuration, Cisco Network Plug and Play and Cisco PnP Connect provide a common provisioning path. The embedded Cisco Business Dashboard probe removes the need for a separate probe appliance. Specify the provisioning workflow and management-system integration before issuing the branch hardware PO.
When a staging bench needs packet capture before production rollout, port mirroring can send traffic from eight source ports to one destination port. RSPAN also supports remote capture across a Layer 2 domain. Reserve the analyzer connection and specify the required capture arrangement before ordering the staging units.
10G uplinks to distribution
CBS350-48FP-4G-UK has fixed 1G SFP uplinks, not 10G SFP+ uplinks. C1300-48FP-4X provides the same 48-port Gigabit access configuration with four 10G SFP+ uplinks.
Hardware stacking across switches
CBS350-48FP-4G-UK does not support hardware stacking. Multiple units remain separate switching systems even when managed through Cisco Business Dashboard; dashboard grouping does not add stacking capability.
Silent fanless rack operation
CBS350-48FP-4G-UK uses one fan and produces 48.7 dBA at 25°C. The chassis is not fanless, so a silent equipment-location requirement rules out this model.

CBS350-48FP-4G-UK identifies a Cisco Business 350 managed switch: 48 means 48 Gigabit copper ports, FP denotes Full PoE with a 740W budget, and 4G means four Gigabit SFP uplinks. The UK regional suffix covers the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia.
CBS350-48FP-4G-UK supports an HTTP/HTTPS web interface, Textview CLI over console or SSH, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. A Telnet client and Cisco Network Plug and Play provisioning are also available. The embedded Dashboard probe avoids the need for a separate probe appliance.
CBS350-48FP-4G-UK reached end of sale on October 29, 2024, and its last date of support is October 31, 2029. Software maintenance and vulnerability/security support ended October 29, 2025. C1300-48FP-4G is the replacement for buyers moving from the discontinued Cisco Business 350 model.
ORM offers CBS350-48FP-4G-UK new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Both conditions include 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty includes next-business-day advance replacement where available, with applicable service ending October 31, 2029. ORM also provides RMA with advance replacement.
CBS350-48FP-4G-UK replaces the discontinued SG350-52MP-K9-UK and SF350-48MP-K9-UK. SG350-52MP-K9-UK reached end of sale on October 30, 2021; SF350-48MP-K9-UK followed on July 30, 2022. For a purchase based on an older part number, review configuration migration separately from the hardware replacement relationship.
CBS350-48FP-4G-UK provides a shared 740W PoE budget across 48 PoE+ copper ports. Both 802.3af and 802.3at powered devices are supported. The budget is an aggregate allocation, not a promise of maximum output on every port simultaneously; total the endpoint power requirements before selecting quantities.
CBS350-48FP-4G-UK accepts compatible Gigabit SFP transceivers in its four fixed uplink slots, including GLC-SX-MMD for multimode fiber and MGBLX1 for single-mode fiber. GLC-SX-MMD supports distances to 550 m; MGBLX1 supports distances to 10 km. Match the fiber type and optics at both ends of each link.
No, CBS350-48FP-4G-UK does not support hardware stacking. The four Gigabit SFP ports are network uplinks, not stacking interfaces. Cisco Business Dashboard can manage multiple switches, but that management arrangement does not combine their forwarding hardware or turn the units into a single hardware stack.
CBS350-48FP-4G-UK supports static IPv4 routing, RIP v2 and PBR, with up to 990 static routes and 128 IP interfaces. IPv6 routing is also supported. These capabilities provide inter-VLAN forwarding, but the routing feature set is not the same as an enterprise dynamic-routing software tier.
Yes, CBS350-48FP-4G-UK is a 1U rack-mount switch measuring 445 mm wide, 350 mm deep and 44 mm high. The chassis weighs 5.82 kg and includes a mounting kit. Allow for cabling and ventilation when checking rack space rather than sizing from chassis height alone.
CBS350-48FP-4G-UK uses an internal universal AC power supply accepting 100-240V at 50-60 Hz, rather than an external power adapter. Maximum consumption with PoE is 886.42W at 110V and 859.5W at 220V. Use the complete switch consumption, including endpoint power, when sizing upstream electrical capacity.
CBS350-48FP-4G-UK allocates 740W to PoE, while CBS350-48P-4G-UK allocates 370W. Both are discontinued Cisco Business 350 models, so the relevant choice for existing installations is the required aggregate endpoint-power allocation. The Full PoE version suits a larger powered-device load; the other suits a smaller allocation.
CBS350-48FP-4G-UK has four Gigabit SFP uplinks, while CBS350-48FP-4X-UK has four 10G SFP+ uplinks. Both models are discontinued. The 1G model suits an installation retaining Gigabit uplinks; the 10G variant addresses higher-speed uplink connections. Confirm the intended link speed and optics rather than assuming their uplinks are interchangeable.
C1300-48FP-4G is the Catalyst 1300 replacement for the discontinued Cisco Business 350 CBS350-48FP-4G-UK. The distinction is the product generation and migration path, not an increase in the stated access-port count. Existing-installation purchases may retain the Business 350 model; replacement projects should specify the Catalyst successor.
