CBS350-48T-4G-EU is a managed, non-PoE access switch with 48 10/100/1000 RJ-45 ports and four fixed 1G SFP uplinks for small-business networks. Layer 2+ operation adds local IP routing to Ethernet switching for office workgroups and separated network segments. Its Rack-Mount 1U chassis connects locally powered computers, printers, and servers, while dedicated fiber slots handle upstream connections without consuming copper access ports. Within the Cisco Business 350 Series, the discontinued CBS350-48P-4G-EU adds PoE+ when matching an existing powered configuration. The 48-port Gigabit managed switch provides access controls and traffic isolation for business endpoints and guest connections, without requiring an enterprise switch-license tier.

104 Gbps switching capacity provides nonblocking forwarding across the switch's built-in interfaces. 77.38 Mpps at 64-byte packet size gives the small-packet forwarding ceiling for traffic-profile checks. Static routing, RIP v2, and PBR support local IP forwarding, with 990 static routes available for address-plan sizing. CBS350-48T-4G-EU uses 512 MB of DRAM and 256 MB of flash to run its embedded software and retain software images. A shared 3 MB packet buffer allocates storage dynamically across ports. STP/RSTP/MSTP control switching loops, while eight hardware queues offer strict-priority or Weighted Round-Robin scheduling for traffic classes. DHCP snooping and Dynamic ARP Inspection validate address-related traffic at the access edge. Hardware stacking is unavailable on this model; centralized management does not change that hardware limit. Browser access, a scriptable CLI, and SNMP provide configuration and monitoring paths, with dual software images available for firmware maintenance.
CBS350-48T-4G-EU is available new sealed or certified refurbished, with ORM warranties of up to 3-year extended for new units and up to 1 year for certified refurbished units; 30-day returns cover every condition, terms apply. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, optics recognition, PSU status, and fan status; firmware is verified and configurations are wiped to factory default. Specify condition and quantity on the PO; Cisco's separate limited lifetime hardware coverage ends October 31, 2029. ORM accepts POs, offers Net-30 for government, and handles enterprise or volume requirements with RMA with advance replacement and regional stock/RMA across the UK, EU, US, and MEA.

When a branch rollout repeats the same configuration across several sites, text-editable configuration files and SCP-based distribution let the implementation team prepare a common starting configuration. Regional ordering remains separate from software setup, so identify each destination and confirm the supplied power cord before the PO.
When a small-office redesign moves inter-VLAN communication onto the access switch, the 128-IP-interface ceiling becomes an address-plan constraint. Include existing VLAN interfaces and any planned physical-port or link-aggregation interfaces in the design review, then specify the required interface layout before releasing the PO.
When a staging lab needs packet captures before a production change, port mirroring can send traffic from eight source ports to one destination port. Allocate the analyzer connection in the test plan and specify the required capture-port arrangement before ordering the lab unit.
10G uplinks to distribution
CBS350-48T-4G-EU stops at 1G uplinks. C1300-48T-4X provides four 10G SFP+ uplinks while retaining 48 Gigabit copper access ports as the current alternative.
Switch-powered phones and access points
CBS350-48T-4G-EU supplies no PoE. C1300-48P-4G is the current powered alternative, with 48 Gigabit access ports and four 1G SFP uplinks.
Hardware stacking across access switches
CBS350-48T-4G-EU does not support hardware stacking. Cisco Business Dashboard centralizes management, but dashboard enrollment does not create a unified forwarding stack.

CBS350-48T-4G-EU identifies a Cisco Business 350 managed switch: 48 denotes the access-port count, T identifies the non-PoE copper configuration, and 4G denotes four Gigabit SFP uplinks. EU selects regional ordering for the European Economic Area and additional designated markets; EU is not a software-license tier.
CBS350-48T-4G-EU supports an HTTP/HTTPS web interface, CLI through the RJ-45 console or SSH/Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. Browser management offers simple and advanced modes. An embedded Dashboard probe supports centralized administration without a separate on-site probe appliance.
Yes, CBS350-48T-4G-EU 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. C1300-48T-4G is the current replacement for buyers who do not require an exact-model spare.
ORM Systems offers CBS350-48T-4G-EU new sealed or certified refurbished, with up to 3-year extended warranty on new units and up to 1 year on certified refurbished units. Returns are 30 days for every condition, terms apply. Cisco's limited lifetime hardware warranty is separate and ends October 31, 2029.
No additional switch license or subscription is required for CBS350-48T-4G-EU, because all switch features are included with the hardware purchase. There are no switch-license tiers or minimum subscription terms to add to the order; lifecycle support deadlines remain separate from feature entitlement.
CBS350-48T-4G-EU replaces the discontinued SG350-52-K9-EU and SF350-48-K9-EU. SG350-52-K9-EU reached end of sale October 30, 2021, and SF350-48-K9-EU followed July 30, 2022. CBS350-48T-4G-EU is also discontinued, so the forward replacement chain now ends at C1300-48T-4G for a current-model purchase rather than another CBS350 configuration.
GLC-SX-MMD and GLC-LH-SMD are supported 1G transceivers for the Business 350 48-port Gigabit switch, using multimode and single-mode fiber respectively. The four built-in SFP slots require separately ordered optics. Match the fiber type, link distance, and far-end transceiver before specifying the optical parts.
No, CBS350-48T-4G-EU cannot join a hardware stack; stacking in the Cisco Business 350 Series is restricted to selected models with faster uplinks. Cisco Business Dashboard still centralizes administration, but that does not combine these switches into one forwarding system or provide hardware stack membership.
Static routing, RIP v2, and PBR are available on the Business 350 48-port Gigabit switch. The switch supports 990 static routes and 128 IP interfaces, including interfaces on physical ports, link aggregations, and VLANs. These capabilities place this configuration in the Layer 2+ category rather than a routing-license tier.
CBS350-48T-4G-EU uses an internal AC power supply accepting 100-240V AC, without a redundant-supply option. Worst-case consumption is 48.27W at 110V and 48.64W at 220V. Use 48.64W for input-load planning without adding endpoint PoE demand, because the copper access ports do not supply power.
No, the Business 350 48-port non-PoE switch uses one cooling fan, with acoustic noise of 29.7 dBA at 25°C. Buyers placing the unit near occupied workspace should treat this configuration as fan-cooled hardware rather than assuming that a non-PoE small-business switch operates without a fan.
CBS350-48T-4G-EU has no PoE output, whereas discontinued CBS350-48P-4G-EU provides PoE+ with a shared 370W budget. The non-PoE model serves locally powered endpoints; the powered sibling identifies the PoE-equipped configuration when matching discontinued installed hardware. Endpoint power requirements determine whether those configurations are interchangeable.
CBS350-48T-4G-EU has four 1G SFP uplinks, while CBS350-48T-4X-EU has four 10G SFP+ uplinks; both configurations are discontinued. The distinction separates buyers matching a 1G legacy access design from buyers whose installed uplink design requires 10G optics, rather than treating the two configurations as interchangeable spares.
C1300-48T-4G is the current replacement for CBS350-48T-4G-EU, which reached end of sale October 29, 2024. Both configurations provide 48 Gigabit copper access ports and four 1G SFP uplinks. The older model addresses exact-model CBS350 sparing requirements; the successor suits procurement requiring the current replacement generation.
