CBS350-24T-4X-NA combines fanless cooling with managed Layer 2+ switching for small-business offices. Its 24 Gigabit copper access ports connect computers, printers and separately powered devices, while four fixed 10G SFP+ uplinks provide connections to other switches. The 1U rack-mount chassis belongs to the Cisco Business 350 Series and supplies no PoE endpoint power. The discontinued CBS350-24P-4X-NA differs by adding PoE+ for powered endpoints. This 24-port Gigabit switch with 10G uplinks keeps access connections copper-based while leaving the upstream medium to the selected interconnect.
CBS350-24T-4X-NA price for new stock is $1,011.15, a 50% saving from the Cisco list price of $2,022.30. CBS350-24T-4X-NA refurb price is $708.75. CBS350-24T-4X-NA is in stock and available for next-day dispatch. (terms applied)

128 Gbps switching capacity accommodates forwarding across the copper access ports and fixed uplinks. 95.23 Mpps forwarding applies to 64-byte packets, so packet-size assumptions belong in a traffic comparison. CBS350-24T-4X-NA can use static routes or RIP v2, with RIP v2 requiring firmware 3.1 or later. RIP v2 must be enabled globally and per interface, and its interfaces need manually configured IP addresses rather than DHCP-assigned addresses. Static route selection uses the longest matching prefix. Configuration review for a Cisco Business 350 managed switch should therefore separate physical connectivity from the intended routing behavior and confirm the IP addressing plan before enabling dynamic advertisements.
Specify CBS350-24T-4X-NA as new sealed or certified refurbished and state the required condition and interconnects 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 PSU status; firmware is verified and configurations are wiped to factory default. ORM warranties are up to a 3-year extended term for new units and up to 1 year for certified refurbished units, with 30-day returns in either condition; terms apply. POs are accepted, government orders qualify for Net-30, and RMA with advance replacement is available across the UK, EU, US and MEA; specify consistent condition requirements for volume orders.

When adding another member to an existing installation, reserve at least two 10G ports on each switch for stack links and align the firmware version across members. Those ports become stack connections rather than ordinary network links. Specify the topology and required interconnects before the purchase order.
When preparing spare units before installation, use the front USB Type-A port to save and restore configuration files, firmware images and system logs. The USB device must use FAT32. Include the intended configuration files in the staging plan and verify the removable media before specifying the order.
Ethernet power for attached endpoints
Non-PoE ports on CBS350-24T-4X-NA cannot power attached devices. C1300-24P-4X is the current powered alternative with the same 24 Gigabit ports and four 10G SFP+ uplinks.
Ongoing security software remediation
Vulnerability/security support for CBS350-24T-4X-NA ended October 29, 2025. C1300-24T-4X is the current replacement for purchases requiring a successor rather than discontinued hardware.
Legacy SG-series stack expansion
CBS350-24T-4X-NA cannot join legacy SG-series stacks. Replacing an older member requires a separate stack migration rather than adding this model to the existing stack.

CBS350-24T-4X-NA identifies a Cisco Business 350 managed switch: 24T corresponds to 24 non-PoE Gigabit copper ports, 4X to four 10G SFP+ ports, and NA to the regional ordering suffix for the United States, Canada, Mexico and additional Latin American markets. The suffix does not identify a software license tier.
CBS350-24T-4X-NA is managed through the HTTP/HTTPS web interface, a console or SSH/Telnet CLI, SNMP, Cisco Business Dashboard, and the Cisco Business mobile app. Browser-based configuration supports simple and advanced modes. Specify the intended administration method and management access requirements when preparing the initial configuration.
CBS350-24T-4X-NA reached end of sale on October 29, 2024. Software maintenance and vulnerability/security support ended October 29, 2025; remaining entitled Cisco hardware support ends October 31, 2029. C1300-24T-4X is the replacement. Separate hardware coverage from ongoing software remediation when setting the refresh schedule.
ORM Systems offers CBS350-24T-4X-NA new sealed with up to a 3-year extended warranty or certified refurbished with up to 1 year. Returns are available for 30 days in either condition; terms apply. Cisco's limited lifetime hardware warranty is subject to entitlement, with Cisco service ending October 31, 2029.
CBS350-24T-4X-NA replaces SG350X-24-K9-NA and SG550X-24-K9-NA. The older models reached end of sale on October 30, 2021, and July 30, 2022, respectively. Treat either change as a stack migration, not a mixed-generation stack extension, and retain the original part numbers in the replacement purchase order.
Yes, CBS350-24T-4X-NA supports hardware stacking with four members. At least two 10G ports on each switch must be configured for stacking, and all members must run the same firmware version. SFP-H10GB-CU1M, SFP-H10GB-CU3M and SFP-H10GB-CU5M are supported 10G cable options; specify interconnect lengths before ordering.
Yes, the Cisco Business 350 Series supports RIP v2 with firmware 3.1 or later. RIP must be enabled globally and on each participating interface. Those interfaces require manually configured IP addresses. Enable IP routing for route advertisements; with IP routing disabled, RIP learns received routes without sending updates.
CBS350-24T-4X-NA supplies no endpoint power, while CBS350-24P-4X-NA adds PoE+. Both models are discontinued. The non-PoE model suits separately powered devices; the PoE model suits endpoints drawing power over Ethernet. For a current powered replacement, C1300-24P-4X retains 24 Gigabit ports and four 10G SFP+ uplinks.
CBS350-24T-4X-NA has four 10G SFP+ uplinks, while CBS350-24T-4G-NA has four 1G SFP uplinks. Both models are discontinued. The 4X configuration suits a 10G distribution connection; the 4G configuration suits a 1G connection. Keep the uplink speed explicit on a replacement purchase order.
C1300-24T-4X is the current replacement for the discontinued CBS350-24T-4X-NA; both configurations have 24 Gigabit copper ports and four 10G SFP+ uplinks. Retaining the older model suits an existing spares standard. The replacement suits a refresh purchase that no longer requires the discontinued part number.
