CBS350-24FP-4X-NA combines 24 Gigabit Ethernet PoE+ access ports and four fixed 10G SFP+ uplinks in a managed Layer 2+ access switch. The 1U rack-mount chassis belongs to the Cisco Business 350 series and serves small-business networks connecting phones, wireless access points, computers, and video endpoints. Separate access and uplink interfaces let fiber connections coexist with the complete copper endpoint configuration. The discontinued CBS350-24P-4X-NA retains the same port arrangement but provides a smaller shared power allocation. Fixed uplinks require no removable network card, while local routing allows separate workgroups to exchange internal traffic without placing every inter-VLAN flow through an external router.
CBS350-24FP-4X-NA price for new stock is $1,340.85, a 35% saving from the Cisco list price of $2,063.08. CBS350-24FP-4X-NA refurb price is $643.64. CBS350-24FP-4X-NA is in stock and available for next-day dispatch. (terms applied)

128 Gbps switching capacity supports traffic across the access and uplink interfaces, while 95.23 Mpps forwarding capacity defines packet-processing throughput. A 370W shared PoE budget requires aggregate endpoint sizing rather than assuming maximum power on every port. Static routing, RIP v2, and PBR provide local traffic control, with 990 static routes and 128 IP interfaces available for segmentation. 512 MB DRAM supports switch operation, and 256 MB flash provides image storage. CBS350-24FP-4X-NA uses a dynamically shared 1.5 MB packet buffer to accommodate traffic across its ports. STP/RSTP/MSTP provide loop-control options, while LACP supports aggregated connections. Administrators can use SSH command-line access and SNMP monitoring alongside the browser interface. Eight hardware queues provide traffic-priority separation. 451.8W worst-case consumption at 110V is the input figure to use when sizing the upstream power circuit; endpoint power allocation is not the complete AC demand.
ORM Systems offers CBS350-24FP-4X-NA new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on certified refurbished units. Every condition includes 30-day returns, terms apply; Cisco's separate limited lifetime hardware coverage is subject to eligibility and ends with Cisco service on October 31, 2029. Certified refurbished units are inspected and bench-tested, with PoE output verified under load on every powered port, firmware verified, and configuration wiped to factory default. Specify condition and quantity on the purchase order; POs are accepted, Net-30 is available for government, and enterprise or volume orders can include RMA with advance replacement across UK, EU, US, and MEA regional stock and RMA operations.

When replacing discontinued SG350X-24MP-K9-NA, SG550X-24MP-K9-NA, or SG550X-24MPP-K9-NA hardware, this model follows all three predecessors as a migration option. An installed-base purchase still needs separate configuration and cabling checks; attach the outgoing PID and required configuration to the purchase order rather than assuming interchangeability.
When expanding an existing hardware stack, ring and chain topologies create different cabling requirements, and stack control uses active and standby roles. Plan interconnect placement and cross-stack link aggregation before adding equipment; include the intended topology and physical cable lengths in the purchase specification.
When standardizing several small offices, the embedded Cisco Business Dashboard probe removes the need for a separate on-site probe appliance or virtual machine. Text-editable configuration files also support repeatable staging. Identify the management approach and provide the approved configuration file before ordering units for each location.
Multigigabit copper endpoint connections
Fixed copper access ports stop at 1GbE; 10G connectivity is confined to the uplinks. Endpoints requiring 2.5G or 5G access cannot negotiate those speeds on this model.
Acoustically silent fanless operation
The chassis uses one fan and produces 34.8 dBA at 25°C. An installation that requires a fanless switch cannot use this model.
Active software security maintenance
Planned vulnerability support ended October 29, 2025, despite the later hardware support deadline. C1300-24FP-4X is the current migration model for purchases requiring a supported successor.

CBS350-24FP-4X-NA identifies a Cisco Business 350 managed switch: 24 denotes Gigabit access-port count, FP denotes Full PoE with a 370W PoE+ budget, and 4X denotes four 10G SFP+ uplinks. NA is the regional suffix covering the United States, Canada, Mexico, Colombia, Chile, and other Latin American markets.
CBS350-24FP-4X-NA 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. Cisco Network Plug and Play also supports provisioning. The Dashboard probe runs within the switch, avoiding a separate local probe appliance.
CBS350-24FP-4X-NA is discontinued, with end of sale on October 29, 2024. Software maintenance and planned security support ended October 29, 2025, while eligible Cisco service ends October 31, 2029. C1300-24FP-4X is the current replacement; remaining hardware support does not extend the software maintenance deadline.
ORM Systems offers CBS350-24FP-4X-NA new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions include 30-day returns; terms apply. Cisco's separate limited lifetime hardware warranty is bounded by October 31, 2029, when Cisco service ends.
Cisco Business 350 requires no separately purchased switch license or subscription, and all switch features are included with the hardware purchase. There is no minimum switch subscription term or separately ordered feature tier. The regional NA suffix selects the ordering region rather than a software entitlement.
CBS350-24FP-4X-NA replaces discontinued SG350X-24MP-K9-NA, SG550X-24MP-K9-NA, and SG550X-24MPP-K9-NA models. SG350X-24MP-K9-NA ended sale October 30, 2021; the two SG550X models ended sale July 30, 2022. These migration relationships do not establish mixed-generation stacking compatibility, so existing stack membership and configuration requirements need a separate compatibility check.
CBS350-24FP-4X-NA provides a shared 370W PoE budget across 24 PoE+ access ports, with a 30W per-port maximum. Every port cannot simultaneously supply that maximum because 24 × 30W equals 720W. Size the combined endpoint allocation against the shared budget before specifying the powered-device mix.
The Cisco Business 350 configuration uses four fixed 10G SFP+ uplinks and supports SFP-10G-SR for multimode fiber or SFP-10G-LR for single-mode fiber. SFP-H10GB-CU1M provides a 1 m direct-attach copper option. Select the connection by media, distance, and the interface at the other end.
CBS350-24FP-4X-NA supports hardware stacking with a maximum of four members managed as one system. Standard 10G interconnections support ring or chain arrangements, with active and standby stack control. Specify the intended topology and interconnect media rather than treating dashboard grouping as equivalent to hardware stacking.
Cisco Business 350 provides static routing, RIP v2, and PBR, with support for 990 static IPv4 routes and 128 IP interfaces. Routed interfaces can use physical ports, link aggregation groups, VLAN interfaces, or loopback interfaces. Check the required routing method and interface count against these limits before deployment.
CBS350-24FP-4X-NA provides a 370W PoE budget, while CBS350-24P-4X-NA provides 195W. Both models are discontinued and retain the same access-port and uplink arrangement. For installed-base sparing, the higher-budget model accommodates greater aggregate endpoint demand; the lower-budget model fits powered-device allocations that remain within its smaller allowance.
CBS350-24FP-4X-NA carries four 10G SFP+ uplinks, whereas CBS350-24FP-4G-NA carries four 1G SFP uplinks. Both models are discontinued. The 4X configuration suits an existing installation requiring 10G upstream connections; the 4G configuration suits installed-base replacement where the upstream links remain at Gigabit speed.
CBS350-24FP-4X-NA ended sale on October 29, 2024, while C1300-24FP-4X is the current migration model. The replacement retains the 24-port Gigabit Full PoE configuration and four 10G SFP+ uplinks. The discontinued model serves installed-base continuity; the current replacement suits buyers standardizing a new purchase around the successor.
CBS350-24FP-4X-NA is a full-width 1U rack-mount switch measuring 445 mm wide, 345 mm deep, and 44 mm high, with a weight of 4.6 kg. The package includes a mounting kit and power cord. Confirm rack depth and the required regional power connection before ordering.
