CBS350-24FP-4G-NA combines 24 Gigabit Ethernet PoE+ access ports with four fixed 1G SFP uplinks in a managed Layer 2+ switch. The full-width Rack-Mount 1U chassis belongs to the Cisco Business 350 Series and serves small-business networks connecting IP phones, wireless access points and surveillance endpoints. Dedicated fiber uplinks leave the copper access connections available for powered devices, while the fixed uplink architecture has no network-module expansion bay. The discontinued CBS350-24P-4G-NA provides a smaller 195W PoE allocation for installations with lower aggregate endpoint demand. Voice VLAN support separates phone traffic from other endpoint traffic and applies voice-specific quality-of-service treatment. Private VLAN Edge can isolate access devices while allowing communication through uplinks, providing a configuration option for shared office networks that require endpoint separation.
CBS350-24FP-4G-NA price for new stock is $983.85. CBS350-24FP-4G-NA refurb price is $500.85. CBS350-24FP-4G-NA is in stock and available for next-day dispatch. (terms applied)

56 Gbps switching capacity supports wire-speed, nonblocking forwarding across the installed ports. 41.66 Mpps forwarding handles 64-byte packets, distinguishing packet-processing throughput from aggregate bandwidth. 370W of shared PoE power requires endpoint loads to remain within the aggregate allocation rather than treating every powered connection as an independent budget. Static routing, RIP v2 and PBR provide local subnet forwarding and next-hop policy control. CBS350-24FP-4G-NA carries 512 MB of DRAM, 256 MB of flash and a dynamically shared 1.5 MB packet buffer for traffic across all ports. STP/RSTP/MSTP control switching loops, while LACP groups physical connections into logical links. Cisco Business management includes an HTTP/HTTPS web interface, Textview CLI through the console or SSH/Telnet, and SNMP versions 1, 2c and 3. Hardware stacking is not supported on this model; centralized management does not turn separate units into one hardware stack or provide shared stack failover.
ORM Systems supplies CBS350-24FP-4G-NA new sealed or certified refurbished; refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, PoE output under load on every powered port and optics bay recognition, with firmware verified and configurations wiped to factory default. Specify condition, quantity and required optics on the purchase order. ORM warranties run up to 3 years extended for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition, terms apply; Cisco's limited lifetime hardware coverage ends October 31, 2029. Enterprise and volume purchasing supports PO acceptance, Net-30 for government and RMA with advance replacement, with regional stock/RMA coverage across the UK, EU, US and MEA.

When several locations need a common management approach, the embedded Cisco Business Dashboard probe removes the requirement for a separate probe appliance or virtual machine at each site. Include dashboard connectivity, administrative access and the intended site inventory in the rollout requirements before standardizing the order.
When local subnet gateways are moving onto the access switch, the limit of 128 IP interfaces sets a concrete boundary for the addressing plan. Routed interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopbacks. Specify interface assignments and validate the planned subnet count before the purchase order.
When equipment must pass traffic-analysis checks before production handover, port mirroring can send traffic from eight source ports to one destination port. The staging plan should identify the analyzer connection, source selections and acceptance captures. Include those test requirements and the required quantities in the purchase specification.
10G fiber uplinks to distribution
Fixed SFP uplinks stop at 1G, and no network module can add 10G. C1300-24FP-4X provides four 10G SFP+ uplinks while retaining 24 Gigabit powered access ports.
One hardware stack across switches
Hardware stacking is unavailable on this model; multiple units remain independent switches rather than members of a single hardware stack with shared failover control.
Fanless operation near occupied workspaces
One internal fan means the switch is not fanless. A purchasing requirement for passive cooling cannot be met by this configuration.

CBS350-24FP-4G-NA identifies a Cisco Business 350 managed switch with 24 Gigabit access ports, Full PoE and four 1G SFP uplinks. CBS350 names the series; 24 is the access-port count; FP denotes Full PoE; 4G identifies the uplinks. NA is the regional suffix covering the United States and other designated American markets.
The Cisco Business 350 Series supports HTTP/HTTPS web management, Textview CLI through console or SSH/Telnet, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. The web interface offers simple and advanced modes, while CLI and SNMP support scripted or centralized administration. An embedded Dashboard probe runs on the switch.
No separate feature license or mandatory subscription is required for the Cisco Business 350 Series; switch features are included with the hardware purchase. CBS350-24FP-4G-NA does not require an additional network-tier license selection or minimum subscription term. The purchase can specify hardware condition and quantity without adding a switch-feature subscription line.
370W is the shared PoE budget of CBS350-24FP-4G-NA across 24 PoE+ access ports. The switch supports 802.3af and 802.3at powered devices, including compatible phones, wireless access points and cameras. The aggregate allocation, not the Full PoE name alone, determines the endpoint mix that can be powered simultaneously.
Four fixed 1G SFP uplinks are built into CBS350-24FP-4G-NA, and compatible transceivers are ordered separately. MGBSX1 supports multimode fiber links to 500 m; MGBLX1 supports single-mode fiber links to 10 km. Select the transceiver PID against the installed fiber and link distance; the SFP ports are not 10G uplinks.
No, CBS350-24FP-4G-NA cannot join a hardware stack. Hardware stacking within the Cisco Business 350 Series is restricted to selected models with 10G interfaces, not this four-SFP configuration. Cisco Business Dashboard can manage separate switches centrally, but that management grouping does not create shared hardware forwarding or stack failover.
Static routing, RIP v2 and PBR are available on CBS350-24FP-4G-NA for inter-VLAN forwarding and next-hop control. IPv4 static routing supports 990 static routes, with 128 IP interfaces available. Routed interfaces can use physical ports, link aggregation groups, VLAN interfaces or loopback interfaces when defining the local subnet layout.
449.7W at 110V is the worst-case PoE-inclusive power consumption of CBS350-24FP-4G-NA; the corresponding figure at 220V is 438.3W. System consumption without the PoE load is 46.6W at 110V or 46.35W at 220V. Size the AC circuit using the PoE-inclusive figure rather than the system-only draw.
CBS350-24FP-4G-NA replaced the discontinued SG350-28MP-K9-NA and SF350-24MP-K9-NA. SG350-28MP-K9-NA reached end of sale on October 30, 2021; SF350-24MP-K9-NA followed on January 29, 2023. CBS350-24FP-4G-NA is itself discontinued, so an upgrade purchase should distinguish installed-base replacement from migration to the current C1300-24FP-4G.
CBS350-24FP-4G-NA is discontinued, with end of sale on October 29, 2024 and last support on October 31, 2029. Software maintenance and vulnerability/security support ended on October 29, 2025. C1300-24FP-4G is the current replacement, so remaining hardware support should not be confused with continuing software or security maintenance.
CBS350-24FP-4G-NA provides a 370W PoE budget, while the discontinued CBS350-24P-4G-NA provides 195W. Both carry 24 Gigabit PoE+ access ports and four 1G SFP uplinks. The FP model addresses larger aggregate powered loads; the P model fits smaller endpoint budgets within the same port arrangement.
CBS350-24FP-4G-NA has four 1G SFP uplinks, whereas the discontinued CBS350-24FP-4X-NA has four 10G SFP+ uplinks. Both retain 24 Gigabit PoE+ access ports and a 370W budget. The 4G configuration serves existing Gigabit uplink networks; the 4X configuration is for faster aggregation connections.
C1300-24FP-4G is the current replacement for the discontinued CBS350-24FP-4G-NA, whose Cisco end-of-sale date was October 29, 2024. Both configurations provide 24 Gigabit powered access ports and four 1G SFP uplinks. The older model suits installed-base sparing; C1300-24FP-4G suits purchases requiring the current replacement.
ORM Systems offers CBS350-24FP-4G-NA new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Every condition has 30-day returns, terms apply. Cisco's limited lifetime hardware warranty is separate and bounded by the last support date, October 31, 2029.
