Fanless Access Switching for Small Office Networks

CBS350-16P-E-2G combines fanless desktop operation with 16 Gigabit RJ-45 PoE+ access ports and two fixed Gigabit SFP uplinks. This managed Layer 2+ switch uses an external AC adapter and belongs to the Cisco Business 350 Series, serving small-office networks with IP phones, wireless access points and IP cameras. The copper interfaces support 10/100/1000 connections, while separate fiber uplinks leave the powered access interfaces available for endpoints. VLAN segmentation and voice VLAN handling accommodate mixed data and voice traffic without a removable uplink card. The discontinued CBS350-16T-E-2G has the same access-port count and uplink arrangement but does not supply PoE, distinguishing data-only connectivity from endpoint power delivery.

Technical Details

36 Gbps switching capacity provides nonblocking forwarding for local access traffic. 26.78 Mpps forwarding at 64-byte packet size defines the packet-processing ceiling for small-frame workloads. 120W of shared PoE power requires endpoint allocations to remain within the aggregate budget rather than treating every powered port as independently provisioned. Static routing, RIP v2 and PBR handle local IP forwarding and next-hop selection; the static-route limit is 990. STP, RSTP and MSTP protect switching topologies, while LACP forms link-aggregation groups. CBS350-16P-E-2G carries 512 MB of DRAM and 256 MB of flash for switch operation and image storage. Its 1.5 MB packet buffer is shared dynamically across ports, and the 16000-entry MAC table bounds learned Layer 2 addresses. IPv6 routing accommodates dual-stack networks. Hardware stacking is not supported on this model, so additional units remain separate switches rather than members of one unified hardware stack.

Ordering

CBS350-16P-E-2G is offered 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 condition and quantity on the PO, with ORM warranties of up to 3-year extended coverage for new units and up to 1 year for certified refurbished units; every condition has 30-day returns, terms apply. Cisco's Limited Lifetime warranty is bounded by October 31, 2029. Volume procurement includes PO acceptance, Net-30 for government and RMA with advance replacement, supported through UK, EU, US and MEA stock and RMA operations.

Best For

Local Routing Requirements

When a small office needs local forwarding between departmental networks, plan interface addressing around a ceiling of 128 IP interfaces. Physical ports, VLAN interfaces, link-aggregation interfaces and loopback interfaces can participate in the routing configuration. Check the intended interface inventory and addressing plan before specifying the switch quantity on the PO.

Multi-Site Management Standardization

When several small offices are being standardized under Cisco Business Dashboard, the embedded probe runs on the switch rather than on a separate on-site computer or virtual machine. Include site discovery, management access and administrator ownership in the rollout checklist before assigning quantities to each purchase order.

Spare Unit Staging

When spare switches must be staged before entering service, dual firmware images and a front-panel USB Type-A port support image and file handling. Keep the intended configuration in a controlled file, then specify the approved firmware image and configuration-loading procedure before placing the spare-unit PO.

Not Suitable If

10G uplinks to distribution

CBS350-16P-E-2G is limited to Gigabit SFP uplinks. C1300-16P-4X retains 16 Gigabit access ports while providing four 10G SFP+ uplinks for higher-speed distribution connections.

Hardware stacking with unified control

CBS350-16P-E-2G does not support hardware stacking. C1300-16P-4X supports eight-member hardware stacks within C1300 Family 1; cross-family stacking is not supported.

Aggregate endpoint power above 120W

CBS350-16P-E-2G shares a 120W PoE budget. C1300-16FP-2G provides 240W across 16 PoE+ ports and uses an internal power supply rather than an external adapter.

Questions & Answers

What does each part of CBS350-16P-E-2G mean?

CBS350-16P-E-2G identifies a Cisco Business 350 managed switch: CBS350 is the series, 16 is the copper access-port count, P indicates PoE+, E indicates external power, and 2G identifies two Gigabit SFP uplinks. The regional order variant for the United States is CBS350-16P-E-2G-NA.

How is the Cisco Business 350 Series managed?

The Cisco Business 350 Series supports a web UI over HTTP/HTTPS, CLI through the RJ-45 console or SSH/Telnet, Cisco Business Dashboard, the Cisco Business mobile app and SNMP. Browser configuration offers simple and advanced modes, while the CLI supports both scriptable commands and menu-based operation.

What PoE budget does CBS350-16P-E-2G provide?

120W is the shared PoE budget of CBS350-16P-E-2G across its 16 powered access ports. The switch supports PoE+ and PoE endpoints, including IP phones, wireless access points and cameras. Endpoint allocations must remain within the aggregate budget; powered-port count does not guarantee simultaneous maximum output from every port.

Which fiber transceivers work with CBS350-16P-E-2G?

MGBSX1 and MGBLX1 are compatible Gigabit fiber transceiver options for CBS350-16P-E-2G. MGBSX1 supports multimode fiber connections to 500 m, while MGBLX1 supports single-mode fiber connections to 10 km. MGBSX1 or MGBLX1 must be ordered separately and matched to the fiber path and remote-end interface.

What routing capabilities does CBS350-16P-E-2G support?

Static routing, RIP v2 and PBR are supported on CBS350-16P-E-2G, with 990 static routes and 128 IP interfaces. IPv4 and IPv6 forwarding can use physical ports, VLAN interfaces, link-aggregation interfaces or loopback interfaces. The switch is a Layer 2+ configuration with local routing rather than an OSPF-based routed-access model.

Can CBS350-16P-E-2G operate in a hardware stack?

No, CBS350-16P-E-2G does not support hardware stacking, so multiple units cannot operate as one unified hardware stack. Cisco Business Dashboard can manage devices centrally, but that management arrangement does not create shared forwarding or control planes. Each unit remains independently configured and connected to the network.

What power consumption and input does CBS350-16P-E-2G have?

150.1W is the CBS350-16P-E-2G worst-case power consumption with PoE at 110V AC; the corresponding figure at 220V AC is 148.8W. The external AC adapter accepts 100-240V at 50-60 Hz. Electrical provisioning must account for switch operation and endpoint power together.

Is CBS350-16P-E-2G a desktop or rack-mount switch?

Desktop is the CBS350-16P-E-2G form factor, although a mounting kit is included for rack installation. The chassis measures 268 mm wide, 210 mm deep and 44 mm high, with a weight of 1.42 kg. Installation planning must also accommodate the separate external AC adapter.

What is the lifecycle status of CBS350-16P-E-2G?

CBS350-16P-E-2G reached end of sale in its North American order variant on October 29, 2024, with C1300-16P-2G as its current replacement. Software maintenance and vulnerability/security support ended October 29, 2025. Cisco hardware service remains bounded by October 31, 2029, subject to entitlement. These are separate lifecycle milestones.

What condition and warranty options does ORM offer for CBS350-16P-E-2G?

New sealed and certified refurbished CBS350-16P-E-2G units carry separate ORM warranties: up to 3-year extended for new and up to 1 year for refurbished. Every condition has 30-day returns, terms apply. Cisco's Limited Lifetime warranty includes next-business-day advance replacement where available, but Cisco service and warranty end October 31, 2029. Refurbished units are inspected and bench-tested.

What is the difference between CBS350-16P-E-2G and CBS350-16T-E-2G?

CBS350-16P-E-2G supplies PoE+ on its 16 access ports, whereas CBS350-16T-E-2G provides data connectivity without PoE. Both models are discontinued. The powered model suits existing installations using switch-powered endpoints; the data-only model suits installed-base matching where phones, access points or other devices receive power separately.

What is the difference between CBS350-16P-E-2G and CBS350-16P-2G?

CBS350-16P-E-2G uses an external AC adapter, whereas CBS350-16P-2G uses an internal AC power supply. Both models are discontinued and provide the same 120W PoE budget. The external-power version suits matching an existing adapter-based installation; the internal-power version suits installed bases standardized on a direct chassis AC connection.

What is the difference between CBS350-16P-E-2G and C1300-16P-2G?

CBS350-16P-E-2G is discontinued, while C1300-16P-2G is its current migration model. Software maintenance and vulnerability/security support for the North American CBS350 order variant ended October 29, 2025. The older model serves like-for-like installed-base sparing; C1300-16P-2G suits new purchases that do not require matching the discontinued hardware.

What Layer 2 features does the Cisco Business 350 Series support?

STP, RSTP, MSTP, LACP, VLAN segmentation and voice VLAN handling are supported by the Cisco Business 350 Series. The series accommodates 4094 simultaneous VLANs and a 16000-entry MAC table. Voice traffic can receive voice-specific VLAN treatment, while link aggregation groups multiple physical connections into a logical link.

What switching performance does CBS350-16P-E-2G provide?

36 Gbps switching capacity and 26.78 Mpps forwarding are the CBS350-16P-E-2G performance figures, with forwarding measured using 64-byte packets. Nonblocking operation supports wire-speed switching. A 1.5 MB packet buffer is dynamically shared across the ports, so buffering is an aggregate resource rather than dedicated memory for each interface.
