CBS110-24T-NA provides fanless Layer 2 Gigabit switching through 24 dedicated copper access ports and two fixed combo uplinks, each offering copper Ethernet or a 1G SFP connection. The non-PoE desktop chassis serves small offices, workgroups, and departments connecting independently powered equipment. Within the Cisco Business 110 Series, automatic operation addresses basic wired connectivity rather than administrator-defined switching policies. Copper and fiber connections can share the installation, but the two connectors belonging to each combo interface cannot operate simultaneously. The closest powered sibling, CBS110-24PP-NA, adds 12 PoE ports sharing a 100W allocation. The fixed uplink arrangement provides a choice of connection media without requiring a removable uplink card, while retaining Gigabit speed on the upstream connections.
CBS110-24T-NA price for new stock is $223.65. CBS110-24T-NA refurb price is $154.34. CBS110-24T-NA is in stock and available for next-day dispatch. (terms applied)

48 Gbps switching capacity supports nonblocking traffic handling, while 35.7 Mpps forwarding specifies packet-processing performance with 64-byte packets. An 8000-entry MAC table provides address-learning space for connected Ethernet devices. CBS110-24T-NA includes 64 MB of CPU memory and 8 MB of flash, separate from the resources used to buffer traffic. The 2 Mbit packet buffer is dynamically shared across all ports rather than reserved as an independent allowance for each connection. Four hardware queues handle 802.1p priorities through priority queuing and Weighted Round-Robin scheduling. Store-and-forward operation prevents damaged packets from passing through the network, and Head-of-Line blocking prevention addresses forwarding contention. Energy Efficient Ethernet reduces consumption during quiet link periods. Automatic MDI/MDI-X accommodates copper connections without selecting a crossover cable. The Cisco Business 110-24T Unmanaged Switch also runs loop detection and cable diagnostics automatically, making those functions available without administrator configuration.
Specify CBS110-24T-NA as new sealed or certified refurbished, and confirm condition, quantity, and required accessories 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 internal PSU status. ORM coverage is up to 3-year extended warranty for new units and up to 1 year for certified refurbished units, with 30-day returns on every condition; terms apply. For enterprise and volume orders, ORM Systems accepts POs, offers Net-30 for government and RMA with advance replacement, and supports regional stock and RMA across the UK, EU, US, and MEA.

Replacing discontinued SF110-24-NA, SF112-24-NA, SG110-24-NA, or SG112-24-NA equipment provides a named migration path to CBS110-24T-NA. SF110-24-NA ended sales on January 29, 2023; the other three ended sales on October 30, 2021. Match existing connections and installation hardware before placing the replacement PO.
Staging equipment for larger Ethernet frames calls for checking the switch's 9216-byte jumbo-frame support against endpoint behavior. A successful link alone does not establish that the complete traffic path accepts the same frame size. Define the frame-size test cases and connected-device settings before ordering the lab batch.
A multisite CBS110-24T-NA rollout across the United States, Canada, and Mexico uses the same regional ordering suffix. Mounting hardware accompanies the unit and is not offered separately as a spare accessory. Include confirmation of the complete mounting kit and regional power cord in each site's purchase requirements.
10G uplinks to another switch
CBS110-24T-NA limits its fixed combo uplinks to Gigabit Ethernet. The shared copper or SFP interfaces cannot provide a 10G upstream connection.
PoE power for connected devices
CBS110-24T-NA supplies no PoE. CBS110-24PP-NA offers 12 powered ports sharing 100W, while changing to a wider 440 mm chassis.
Administrator-configurable switching functions
CBS110-24T-NA operates without configuration, with automatic traffic prioritization and loop detection. These automatic functions do not provide an administrator-configurable switching environment.

CBS110-24T-NA identifies a Cisco Business 110 unmanaged, non-PoE Gigabit switch: CBS110 is the family, 24T selects the copper configuration with two shared SFP uplinks, and NA is the regional suffix. The NA variant covers the United States, Canada, Mexico, Colombia, Chile, and other Latin American markets.
Cisco Business 110 switches operate without configuration: connect power and Ethernet devices, and the ports automatically select link speed and duplex. Traffic prioritization, loop detection, and cable diagnostics also run automatically. The unmanaged operating model does not require an administrator to set these functions before network connections become active.
Cisco has not announced an end-of-sale date for Business 110. CBS110-24T-NA replaces several discontinued Small Business switches, but their retirement milestones belong to those older products rather than this ordering number. The replacement model and its predecessors therefore need separate lifecycle records when planning hardware purchases.
ORM Systems offers CBS110-24T-NA new sealed or certified refurbished, with ORM warranties of up to 3-year extended coverage for new units and up to 1 year for refurbished units. Cisco's separate platform warranty is limited lifetime, subject to eligibility and terms. Every condition includes 30-day returns; terms apply.
CBS110-24T-NA accepts MGBSX1 for multimode fiber to 500 m, MGBLX1 for single-mode fiber to 10 km, MGBLH1 for single-mode fiber to 40 km, and MGBT1 for copper to 100 m. Each operates at 1G; each combo interface uses either its copper connector or SFP cage, not both simultaneously.
CBS110-24T-NA uses an internal AC power supply accepting 100-240V at 50-60 Hz. Worst-case consumption is 17.79W at 110V and 17.49W at 220V. The power connection is separate from the Ethernet ports, so the installation needs a local AC outlet and the appropriate regional power cord.
Yes, CBS110-24T-NA supports rack installation with mounting hardware, although its 279 mm-wide chassis is a desktop form factor rather than a full-width rack chassis. The unit measures 170 mm deep and 44 mm high. A mounting kit accompanies the switch, making complete mounting hardware an order-level consideration.
CBS110-24T-NA replaces discontinued SF110-24-NA, SF112-24-NA, SG110-24-NA, and SG112-24-NA switches. SF110-24-NA reached end of sale on January 29, 2023; the other three reached end of sale on October 30, 2021. These are predecessor retirement dates, not an end-of-sale announcement for the replacement model.
CBS110-24PP-NA provides 12 PoE ports sharing 100W, whereas CBS110-24T-NA supplies no endpoint power. The non-PoE model suits equipment with independent power sources. The partial-PoE model suits orders requiring switch-delivered endpoint power, provided the powered-port count and aggregate demand stay within its limits.
CBS110-24T-NA has an internal AC supply, while CBS110-8T-D-NA uses an external universal AC adapter. The latter is also an eight-port desktop model, not a same-density power option. The internally powered model suits higher connection counts; the eight-port model suits smaller installations where an external adapter is acceptable.
CBS110-24T-NA provides 26 Gigabit Ethernet connections, compared with 16 on CBS110-16T-NA. Two connections on the higher-density model are shared copper/SFP combo interfaces. The 26-connection model suits higher attachment counts; the 16-port model suits purchases that can accommodate all required links within its smaller connection count.
