SF112-24-NA combines fanless operation with 24 10/100 Mbps access ports and two fixed Gigabit combo uplinks for small-business Ethernet connections. This Layer 2, non-PoE switch belongs to the Cisco 110 Series Unmanaged Switches and occupies one rack unit in a full-width chassis. Each uplink offers a copper connection or a shared SFP cage, allowing the connection medium to match the upstream link without adding an expansion card. The Cisco SF112-24 serves existing Fast Ethernet endpoints rather than providing Gigabit speed at every access connection. Unlike the discontinued SF110-24-NA, which lacks Gigabit uplinks, this model provides separate faster connections upstream.

8.8 Gbps switching capacity handles aggregate traffic across the built-in connections, while 6.5 Mpps forwarding at a 64-byte packet size defines packet-processing throughput. Four hardware queues combine priority queuing with Weighted Round-Robin scheduling to handle traffic priorities automatically. SF112-24-NA operates without configuration, and automatic MDI/MDI-X handles copper crossover selection. Store-and-forward switching rejects damaged packets before they pass to another connection. Loop detection helps identify accidental network loops, while cable diagnostics help identify cabling faults and shorts. The internal universal supply accepts 110-240V AC at 50-60 Hz, so installation uses a mains power cord rather than an external adapter. An operating range of 0°C to 40°C sets the ambient-temperature requirement for the equipment location; account for enclosure conditions when specifying installation space.
Order SF112-24-NA new sealed or certified refurbished, and specify condition, quantity, the regional power cord, and any fiber-link components on the PO. Certified refurbished units are inspected and bench-tested, with every port linked at rated speed, optics bay recognition checked, and internal PSU status verified; checks also cover power-on and POST and a clean boot. ORM's new-unit warranty is up to 3-year extended, certified refurbished coverage is up to 1 year, and every condition has 30-day returns; terms apply. For enterprise and volume orders, PO acceptance, Net-30 for government, RMA with advance replacement, and regional stock/RMA coverage across the UK, EU, US, and MEA apply.

When adding like-for-like reserve hardware across American sites, the -NA regional version covers the United States, Canada, Mexico, Colombia, Chile, and the rest of Latin America. Regional identity matters when matching an existing purchase record, so specify the complete SF112-24-NA part number rather than an unsuffixed model name.
When staging equipment for an existing network that uses larger Ethernet frames, the 9216-byte jumbo-frame ceiling provides a concrete compatibility check. Frame handling also depends on the connected equipment, so include the intended frame size and the devices at both ends in the acceptance-test requirements before issuing the PO.
Gigabit speed at every endpoint
SF112-24-NA limits access links to 100 Mbps. CBS110-24T-NA provides Gigabit access connections, but its narrower 279 mm chassis has a desktop form factor.
Power delivery to Ethernet endpoints
SF112-24-NA does not power connected endpoints. CBS110-24PP-NA provides 12 PoE ports with a shared 100W budget and also changes access connections to Gigabit Ethernet.
10G uplinks to distribution
SF112-24-NA provides Gigabit combo uplinks only; neither the copper uplink connection nor the shared SFP cage supports a 10G uplink.

SF112-24-NA identifies the SF112 switch with 24 Fast Ethernet access ports, two Gigabit combo uplinks, and the -NA regional suffix. The 24 segment gives the access-port count. The -NA suffix covers the United States, Canada, Mexico, Colombia, Chile, and the rest of Latin America.
Cisco 110 Series Unmanaged Switches operate without configuration, using automatic speed, duplex, and MDI/MDI-X selection for connected copper devices. SF112-24-NA also handles traffic prioritization automatically through four hardware queues, priority queuing, and Weighted Round-Robin scheduling. Connect the required Ethernet cables and AC power rather than preparing an administrator configuration.
SF112-24-NA is discontinued: Cisco ended sales on October 30, 2021, and the last date of support is October 31, 2026. CBS110-24T-NA is the replacement. Existing Cisco service or warranty entitlement cannot extend support beyond that final date, so replacement and spare orders need a defined coverage horizon.
SF112-24-NA is offered new sealed or certified refurbished, with ORM warranties of up to 3-year extended for new units and up to 1 year for refurbished units. Both conditions have 30-day returns; terms apply. Cisco's limited lifetime hardware warranty is bounded by October 31, 2026, the last date of support.
SF112-24-NA has two fixed Gigabit combo uplinks, each offering a copper connection or an SFP connection. The shared connections do not provide four independent uplinks. Decide whether each upstream link will use copper or fiber before ordering its cabling and any required compatible fiber transceivers.
SF112-24-NA uses an internal universal AC power supply accepting 110-240V at 50-60 Hz. A power cord connects the chassis directly to mains power; an external AC adapter is not required. Include the correct regional power cord in the order requirements and confirm the installation location has a suitable AC connection.
The Cisco SF112-24 fits a full-width 1U rack position, with a chassis measuring 440 mm wide, 203 mm deep, and 44 mm high. Its weight is 1.93 kg. Reserve the required equipment space and confirm mounting hardware is included in the selected-condition order before issuing the PO.
SF112-24-NA provides 8.8 Gbps switching capacity and 6.5 Mpps forwarding for 64-byte packets. Store-and-forward switching rejects damaged packets, while loop detection and cable diagnostics operate automatically. Use the packet rate when considering small-packet traffic and the switching-capacity figure when reviewing aggregate bandwidth; neither changes the speed of the access connections.
SF112-24-NA does not provide PoE on its access ports, so connected phones, access points, and other endpoints need their own power arrangements. Ethernet connectivity alone does not power those devices. Specify endpoint power supplies or a different powered-switch configuration when the purchase includes devices requiring power through Ethernet.
SG110-24HP-NA provides 12 PoE ports with a shared 100W budget, while SF112-24-NA supplies no endpoint power. Both models are discontinued. SF112-24-NA suits like-for-like replacement of self-powered connections; SG110-24HP-NA suits a legacy spare requirement where endpoint power is part of the existing design.
SF112-24-NA adds two Gigabit combo uplinks, while SF110-24-NA provides 24 Fast Ethernet ports without Gigabit uplinks. Both products are discontinued. SF112-24-NA suits a like-for-like spare requirement with separate faster upstream links; SF110-24-NA fits an existing Fast Ethernet layout that does not require those uplinks.
CBS110-24T-NA provides Gigabit access connections where SF112-24-NA provides 10/100 Mbps access connections. CBS110-24T-NA is the replacement for the discontinued model. Buyers retaining Fast Ethernet hardware can specify SF112-24-NA for like-for-like spares; buyers changing endpoint connections to Gigabit should use CBS110-24T-NA rather than treating faster uplinks as an access-port upgrade.
