Fanless Fiber Connectivity for Small Office Networks

CBS350-8S-E-2G-UK is a fanless, managed Layer 2+ desktop switch with eight dedicated Gigabit SFP ports and two fixed Gigabit copper/SFP combo uplinks. Each combo interface accepts either a copper connection or an SFP connection, giving ten simultaneous network ports rather than twelve. The non-PoE configuration connects separately powered equipment and fiber links without allocating an endpoint power budget. Within the Cisco Business 350 Series, this model provides a compact fiber-oriented configuration for small office networks. The discontinued CBS350-24S-4G uses an internal power supply, whereas this 8-port Gigabit SFP switch uses an external AC adapter. Uplink expansion depends on the existing fixed interfaces rather than a removable network card.

Technical Details

20 Gbps switching capacity supports nonblocking Gigabit operation, while 14.88 Mpps forwarding handles minimum-size Ethernet packets at wire speed. Static routing, RIP v2 and PBR provide local routing and policy-controlled next-hop selection, with 990 static routes and 128 IP interfaces available for the routed design. CBS350-8S-E-2G-UK combines 512 MB of DRAM with 256 MB of flash for its managed operating environment. A dynamically shared 1.5 MB packet buffer accommodates traffic across the interfaces rather than reserving a separate allocation for each port. The address table holds 16000 MAC entries, and support for 4094 simultaneous VLANs allows separate broadcast domains within the same chassis. STP, RSTP and MSTP provide spanning-tree options, while LACP supports aggregated links. Hardware stacking is not supported, so centralized administration does not combine multiple chassis into one forwarding system.

Ordering

Specify new sealed or certified refurbished condition for CBS350-8S-E-2G-UK, and confirm quantity and included accessories on the purchase order. Certified refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition and rated adapter output; firmware is verified and configurations are wiped to factory default. ORM provides up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's separate limited lifetime warranty is bounded by service ending May 31, 2029. Enterprise and volume orders support PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock and RMA coverage in the UK, EU, US and MEA.

Buying Notes

Buying NotesKey Specs

Security maintenance has ended

CBS350-8S-E-2G-UK requires lifecycle review before deployment because software maintenance and vulnerability support ended May 30, 2025. Remaining hardware support entitlement does not extend the software security-maintenance period.

Specify optics by fiber type

Fiber connections require compatible transceivers: MGBSX1 serves multimode links, while MGBLX1 serves single-mode links. Match the fiber type and the equipment at both ends before adding optics to the purchase order.

Legacy Fiber Fleet Refresh

An installed SG350-10SFP-K9-UK fleet creates a specific replacement-matching requirement because its end-of-sale date was July 30, 2022. Preserve the existing link inventory and regional ordering identity when preparing replacement quantities. Confirm the installed optics, connection media and required configuration before specifying the replacement units on the purchase order.

Multi-Site Configuration Standardization

A rollout across several offices can use text-editable configuration files and secure SCP downloads to standardize the initial setup. Cisco Network Plug and Play also supports provisioning workflows. Separate the common configuration from site-specific addressing, then specify the required staging work and configuration ownership before placing the purchase order.

Lab And Staging Preparation

A staging bench that separates installation work from administration can use CLI privilege levels 1, 7 and 15. Full and menu-based CLI operation support different technician workflows. Establish the permitted commands, acceptance checks and handover credentials before specifying the staging procedure and the quantity of units required for the order.

Not Suitable If

10G uplinks to distribution

The fixed uplinks operate at Gigabit speed, and the chassis has no removable uplink card bay. Installing an SFP does not provide a 10G interface.

PoE for attached endpoints

The copper combo interfaces do not supply PoE. Phones, cameras and access points requiring power through their Ethernet connection need a separate power arrangement.

Hardware stacking across multiple switches

The chassis does not support hardware stacking. Shared management tools do not create a unified forwarding system, shared stack control plane or stack interconnect.

Questions & Answers

What does each segment of CBS350-8S-E-2G-UK mean?

CBS350-8S-E-2G-UK identifies a Cisco Business 350 managed switch: 8S denotes eight Gigabit SFP ports, E denotes external power, and 2G denotes two Gigabit copper/SFP combo ports. UK is the regional ordering suffix for the United Kingdom, Saudi Arabia, Qatar, Kuwait, Singapore, Hong Kong and Malaysia.

How is CBS350-8S-E-2G-UK managed?

CBS350-8S-E-2G-UK supports a web UI over HTTP/HTTPS, CLI over console or SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app, SNMP and Network Plug and Play. The CLI provides full and menu-based operation, while an embedded Dashboard probe removes the need for a separate probe appliance.

What is the lifecycle status of CBS350-8S-E-2G-UK?

CBS350-8S-E-2G-UK reached end of sale on May 30, 2024, and its last support date is May 31, 2029. Software maintenance and vulnerability support ended May 30, 2025. No migration product is available for this model, so deployment planning needs to account for the remaining support boundary.

What condition and warranty does ORM Systems offer for CBS350-8S-E-2G-UK?

ORM offers CBS350-8S-E-2G-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 every condition for 30 days, terms apply. Cisco's limited lifetime warranty is bounded by its last support date of May 31, 2029.

Which older switch does CBS350-8S-E-2G-UK replace?

CBS350-8S-E-2G-UK replaces the discontinued SG350-10SFP-K9-UK, whose end-of-sale date was July 30, 2022. That replacement relationship identifies the matching regional fiber-switch migration, not a promise of configuration-file interchangeability. Include the exact regional part number when matching an installed unit or preparing a like-for-like spare.

How many simultaneous connections does CBS350-8S-E-2G-UK support?

CBS350-8S-E-2G-UK has eight dedicated Gigabit SFP ports plus two Gigabit copper/SFP combo ports, giving ten logical network ports. Each combo port uses either its RJ-45 connector or its SFP cage, not both simultaneously. Specify which medium each shared port will use before choosing optics and patch leads.

Which routing functions are available on CBS350-8S-E-2G-UK?

Static routing, RIP v2 and PBR are available on CBS350-8S-E-2G-UK, with 990 static routes and 128 IP interfaces. These functions support routing between local network segments and policy-controlled next-hop selection. Size the configuration against those limits rather than assuming that the chassis carries an enterprise routing software tier.

How is the Business 350 eight-port SFP switch powered and cooled?

The Business 350 eight-port SFP switch uses an external AC adapter with a 100-240V AC input and fanless cooling. Worst-case system consumption reaches 11.9W. Include the adapter in the equipment acceptance check, and allow for its placement when preparing a desktop installation or equipment shelf.

Can the Business 350 eight-port SFP switch join a hardware stack?

No, the Business 350 eight-port SFP switch does not support hardware stacking. Shared Cisco Business management tools do not turn this model into a single forwarding system with other switches. Treat each chassis as a separate network device when planning uplinks, configuration ownership and the quantity of operational spares.

What is the difference between CBS350-8S-E-2G-UK and CBS350-8P-E-2G?

CBS350-8S-E-2G-UK supplies no PoE, whereas the discontinued CBS350-8P-E-2G provides a 60W shared PoE+ budget. The fiber model suits separately powered equipment; the copper PoE+ model serves powered endpoints. These discontinued variants are not interchangeable when the purchase order must include endpoint power delivery.

What is the difference between CBS350-8S-E-2G-UK and CBS350-24S-4G?

CBS350-8S-E-2G-UK uses an external AC adapter, while the discontinued CBS350-24S-4G uses an internal universal AC supply. Their fiber-port density also differs: eight dedicated SFP ports versus twenty-four. The smaller model matches compact external-adapter installations; the larger chassis belongs to higher-density installations with an internal-supply requirement.

What is the difference between CBS350-8S-E-2G-UK and CBS350-12XS?

CBS350-8S-E-2G-UK has Gigabit SFP interfaces, whereas the discontinued CBS350-12XS has 10G SFP+ interfaces. The former matches existing Gigabit fiber links; the latter belongs to a higher-speed fiber installation. Both models are discontinued, so compare installed link requirements rather than treating either as a current-generation upgrade.
