CBS350-24S-4G-NA is a fanless, managed Gigabit fiber switch with 24 SFP access ports and four fixed Gigabit uplinks. Two uplinks provide shared copper/SFP connections; the other two are dedicated SFP slots. The non-PoE, rack-mount unit belongs to the Cisco Business 350 series and supports Layer 2+ operation, including static routing and RIP v2. Its optical access connections distinguish this configuration from copper endpoint switches. For an existing fiber installation, plan the purchase around the installed cabling and the transceivers at both ends rather than the port count alone.
CBS350-24S-4G-NA price for new stock is $1,151.85. CBS350-24S-4G-NA refurb price is $1,004.85. CBS350-24S-4G-NA is in stock and available for next-day dispatch. (terms applied)

56 Gbps switching capacity and 41.66 Mpps forwarding provide separate throughput measures for traffic planning. CBS350-24S-4G-NA has 512 MB DRAM, 256 MB flash and a shared 1.5 MB packet buffer. RIP v2 supports dynamic routing, while PBR allows next-hop selection using access-control rules. Browser configuration and a scriptable CLI give administrators different ways to stage changes; save and verify the intended configuration before placing a spare into service. Hardware stacking is not supported on this model, so centralized monitoring must not be treated as a shared forwarding or control plane.
Specify CBS350-24S-4G-NA, quantity and condition 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, every port linking at rated speed, clean boot, optics bay recognition and PSU status; firmware is verified and configurations are wiped to factory default. New units carry up to 3-year extended warranty and certified refurbished units up to 1 year, with 30-day returns on every condition; terms apply. For enterprise and volume orders, PO acceptance, Net-30 for government and RMA with advance replacement apply, with regional stock and RMA across the UK, EU, US and MEA.

When replacing an installed SG350-28SFP-K9-NA, use the named replacement relationship as the starting point, not as proof that the existing configuration can be copied unchanged. Inventory the optical connections, export the configuration and compare the required settings before specifying the replacement order.
When several small-business sites need centralized monitoring, the embedded Cisco Business Dashboard probe avoids a separate probe appliance at each location. For rollout planning, establish who will administer the Dashboard, how each site will connect and which management credentials must be provisioned before the purchase order.
10G uplinks over existing fiber
The fixed uplinks operate at 1G, so this configuration cannot satisfy a 10G uplink requirement. Specify a different configuration rather than ordering faster optics for these slots.
Hardware stacking with shared control
This model does not support hardware stacking. A requirement for shared forwarding and control across multiple chassis therefore rules out this configuration, regardless of centralized management.
Ongoing scheduled security remedies
Scheduled vulnerability and security support ended May 30, 2025. No migration product is named for this model, so a new deployment requiring ongoing remedies needs another selection.

CBS350-24S-4G-NA identifies a Cisco Business 350 managed switch: 24S denotes 24 Gigabit SFP access ports, and 4G denotes four Gigabit uplinks. NA is the regional ordering suffix covering the United States, Canada, Mexico, Colombia, Chile and the rest of Latin America.
CBS350-24S-4G-NA supports browser management, CLI access through the console, SSH or Telnet, SNMP, Cisco Business Dashboard and the Cisco Business mobile app. For deployment planning, select the administration method and provision its credentials before staging the unit rather than leaving management access to the installation visit.
CBS350-24S-4G-NA reached end of sale on May 30, 2024, and its last date of support is May 31, 2029. Software maintenance and scheduled security remedies ended May 30, 2025. Cisco names no migration product for this model; plan purchases as discontinued-hardware procurement.
ORM Systems offers CBS350-24S-4G-NA new sealed or certified refurbished, with up to 3-year extended warranty on new units and up to 1 year on refurbished units. Both conditions have 30-day returns; terms apply. Cisco's separate limited lifetime platform warranty is bounded by May 31, 2029.
CBS350-24S-4G-NA requires no switch license or subscription, and its features are included with the hardware purchase. There is no switch subscription tier or minimum term to select. For procurement, keep any separately scoped management services distinct from the hardware line item on the purchase order.
CBS350-24S-4G-NA is the named replacement for SG350-28SFP-K9-NA, which reached end of sale on July 30, 2022. For a legacy replacement project, review the installed optics, cabling and required configuration before ordering; the replacement relationship alone is not a configuration-migration plan.
CBS350-24P-4G-NA provides powered copper access ports, whereas CBS350-24S-4G-NA provides non-PoE SFP access ports. Both models are discontinued. For an existing installation, the copper configuration addresses endpoints requiring network-delivered power; the SFP configuration addresses optical connections, so the installed connection medium determines which legacy configuration is relevant.
CBS350-24S-4G-NA uses an internal AC power supply, while CBS350-8S-E-2G-NA uses an external supply and has fewer optical access ports. Both are discontinued. For legacy replacement planning, the larger configuration serves a higher-density installation; the smaller configuration requires retaining an external-adapter arrangement in the equipment layout.
CBS350-24XS-NA provides 10G SFP+ connections, whereas CBS350-24S-4G-NA provides Gigabit SFP connections. Both models are discontinued. For an existing installation, the Gigabit configuration addresses established 1G optical links; the 10G configuration addresses a different link-speed requirement and must not be treated as an optics-only upgrade to this switch.
No, the Business 350 24-port SFP switch does not support hardware stacking. Centralized management does not change that limitation. For network planning, treat each chassis as a separate switching unit and verify the inter-switch topology rather than specifying this model for a shared hardware-stack control plane.
