CBS350-24S-4G-EU provides fanless, managed Layer 2+ switching for small-business networks with predominantly fiber connections. Its 24 dedicated Gigabit SFP access slots connect optical links, while four fixed Gigabit uplinks comprise two dedicated SFP slots and two copper/SFP combo interfaces. Each combo interface uses either its copper connection or its SFP slot, not both simultaneously. The rack-mount chassis belongs to the Cisco Business 350 family and supplies no PoE to endpoints. Browser configuration, Cisco Business Dashboard, and the Cisco Business mobile app provide management paths for administrators maintaining individual switches or multiple locations. The discontinued CBS350-8S-E-2G-EU uses an external power supply instead of the internal AC supply fitted here, making power architecture a relevant distinction when maintaining existing fiber-switch installations.

56 Gbps switching capacity accommodates nonblocking forwarding across the available interfaces. 41.66 Mpps forwarding performance applies to 64-byte packets, providing a packet-rate reference for traffic sizing rather than a substitute for uplink bandwidth. Static routing and RIP v2 support communication between IP networks, while PBR directs traffic toward selected next hops. The routing feature set does not include OSPF. CBS350-24S-4G-EU combines 512 MB DRAM with 256 MB flash for operating software and configuration storage. A dynamically shared 1.5 MB packet buffer absorbs traffic bursts across ports. STP, RSTP, and MSTP control switching loops; LACP groups physical connections into logical links. DHCP snooping and dynamic ARP inspection provide controls against unauthorized address information. SSH supports encrypted command-line administration, and SNMP supports integration with monitoring systems. 34.3W maximum consumption provides the upper published system-power figure for sizing the AC load without allocating an endpoint-power budget.
Specify condition, quantities, optical accessories, and regional power requirements for CBS350-24S-4G-EU on the purchase order; ORM Systems offers new sealed and certified refurbished units. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed port links, clean boot, optics bay recognition, and PSU status, with firmware verified and configuration wiped to factory default. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and every condition includes 30-day returns; terms apply. For enterprise and volume orders, PO accepted, Net-30 for government, and RMA with advance replacement are available, with regional stock and RMA coverage across the UK, EU, US, and MEA.

When several branches need a repeatable configuration process, Cisco Network Plug and Play support provides a provisioning path that includes Cisco PnP Connect. Treat device onboarding as part of the purchase scope rather than a separate installation assumption. Specify the provisioning workflow and configuration ownership before issuing the purchase order.
When an existing network requires several aggregated connections, the switch supports eight link-aggregation groups with eight active ports per group. Those limits govern how connections can be grouped independently of the physical port inventory. Map the proposed groups and their member interfaces before specifying quantities and connection accessories.
When a staging environment needs packet capture before production changes, port mirroring can direct traffic from eight source ports to one destination port. Reserve the analyzer connection in the interface plan rather than treating every connection as production capacity. Specify the capture arrangement and required optical connections before ordering.
10G optical uplinks
The fixed uplinks operate at Gigabit speed, and the chassis has no removable uplink card. A requirement for 10G optical connectivity exceeds this model's interface capabilities.
Hardware stacking across multiple switches
This model does not support hardware stacking. Dashboard management does not combine separate switches into one forwarding system, so a hardware-stack requirement excludes this configuration.
Ongoing scheduled security maintenance
Scheduled vulnerability and security support ended May 30, 2025. Deployments requiring continuing scheduled security remedies should not treat the remaining hardware-support period as continuing software maintenance.

CBS350-24S-4G-EU identifies a Cisco Business 350 managed switch: 24S denotes 24 Gigabit SFP access connections, and 4G denotes four Gigabit uplinks. Those uplinks comprise two dedicated SFP connections and two copper/SFP combo connections. EU is the regional ordering suffix covering the European Economic Area and other designated markets.
CBS350-24S-4G-EU supports a web interface, CLI through the console or SSH and Telnet, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. Cisco Network Plug and Play also supports provisioning. The embedded Dashboard probe avoids requiring a separate local probe appliance or virtual machine.
CBS350-24S-4G-EU reached end of sale on May 30, 2024, and its last date of support is May 31, 2029. Software maintenance releases and scheduled vulnerability or security support ended May 30, 2025. No migration product is named for this model, so hardware availability must not be confused with continuing software maintenance.
New sealed and certified refurbished CBS350-24S-4G-EU units are offered by ORM Systems. New units include up to a 3-year extended warranty; certified refurbished units include up to 1 year. Every condition includes 30-day returns; terms apply. Cisco's separate limited lifetime warranty remains subject to eligibility, with Cisco service ending May 31, 2029.
CBS350-24S-4G-EU replaces SG350-28SFP-K9-EU, whose end-of-sale date was July 30, 2022. The replacement retains a Gigabit SFP-oriented configuration for buyers maintaining fiber-connected networks. Both models are discontinued, so this relationship identifies a legacy migration path rather than a currently selling successor for a new standardization program.
Yes, CBS350-24S-4G-EU supports inter-VLAN routing through static routes and RIP v2, with PBR available for next-hop selection. The switch supports 990 static routes and 128 IP interfaces. Its routing capabilities place it in the Layer 2+ category; OSPF is not part of this model's routing feature set.
The CBS350-24S-4G-EU configuration provides two logical combo connections, each offering a choice between copper Ethernet and an SFP slot. Only one medium operates on each combo connection at a time. Two additional dedicated SFP uplinks bring the uplink total to four without creating extra simultaneous connections from the shared interfaces.
CBS350-24S-4G-EU supports Gigabit optics including MGBSX1 for multimode fiber and MGBLX1 for single-mode fiber. MGBSX1 supports a published maximum distance of 500 m, while MGBLX1 supports 10 km. Match the transceiver PID, installed fiber, and remote interface before specifying the optical accessories for each connection.
No, CBS350-24S-4G-EU cannot join a hardware stack, despite hardware stacking being available on selected other Business 350 models. Central management through Cisco Business Dashboard does not change that restriction. Keep the requirement for shared monitoring separate from a requirement for one combined forwarding and control system.
CBS350-24P-4G-EU provides PoE+ on 24 copper access ports with a 195W shared budget, whereas CBS350-24S-4G-EU provides unpowered SFP access connections. Both are discontinued models. The copper configuration addresses powered endpoint connections in legacy installations; the SFP configuration addresses installations whose access connections use optical transceivers.
CBS350-24S-4G-EU uses an internal AC power supply, while CBS350-8S-E-2G-EU uses an external power supply. Both are discontinued fiber-oriented models, but the smaller model also reduces dedicated SFP access connections from 24 to eight. Existing installations determine whether internal power or an external adapter is the appropriate replacement architecture.
CBS350-24XS-EU provides 10G SFP+ connectivity, while CBS350-24S-4G-EU provides Gigabit SFP connectivity. Both models are discontinued, and the 10G model's named replacement is C1300-24XS. The Gigabit configuration addresses existing 1G optical connections; buyers comparing the legacy 10G configuration must account for its different interface speed and migration path.
