SF112-24 provides fanless, unmanaged Layer 2 connectivity through 24 Fast Ethernet access ports and two fixed Gigabit combo uplinks in a full-width rack chassis. Each uplink shares its copper and mini-GBIC interfaces, so those interfaces do not create separate links within the same pair. The Cisco 110 Series Unmanaged Switches connect computers, printers, and other office equipment without administrator configuration. This non-PoE model requires connected endpoints to have their own power sources. SG110-24HP is a discontinued powered sibling with 12 PoE ports. Within the Cisco Small Business range, this configuration separates basic 10/100 endpoint connectivity from Gigabit upstream connections; buyers should establish endpoint-speed and power requirements before treating different office switches as interchangeable.
SF112-24 price for new stock is $131.25, a 53.5% saving from the Cisco list price of $282.25. SF112-24 refurb price is $219.12. SF112-24 is in stock and available for next-day dispatch. (terms applied)

8.8 Gbps switching capacity and 6.5 Mpps forwarding at a 64-byte packet size define the traffic envelope for matching existing switching equipment. Four hardware queues use 802.1p priority, priority queuing, and Weighted Round-Robin (WRR) to handle competing traffic automatically. SF112-24 negotiates port speed and duplex and supports automatic MDI/MDI-X cable detection, avoiding manual crossover-cable selection. Store-and-forward processing identifies damaged packets before forwarding, while head-of-line blocking prevention handles contention within the switching path. Cable diagnostics and loop detection perform connection checks without administrator-defined policies. An internal universal supply accepts 110-240V AC at 50-60 Hz, allowing direct mains connection rather than an external desktop adapter. These automatic functions do not provide a configurable management interface.
SF112-24 is available from ORM Systems new sealed or certified refurbished; new units carry up to a 3-year extended warranty, certified refurbished units up to a 1-year warranty, and every condition includes 30-day returns, with terms applying. Certified refurbished units are inspected and bench-tested for power-on and POST, a clean boot, every port linking at rated speed, optics bay recognition, and internal PSU status. Specify the condition, regional mains cord, mounting hardware, and connection requirements on the purchase order for this switch. ORM Systems accepts POs and government Net-30 terms for enterprise and volume orders, with UK, EU, US, and MEA stock/RMA coverage and RMA with advance replacement.

In a growing small-to-medium business, the Cisco SF112-24 switch delivers 24 Fast Ethernet ports plus 2 Gigabit Ethernet and 2 Mini-GBIC uplinks to the core router. This setup enables seamless segmentation of departments, high-speed data transfers, and future-proof fiber uplinks. Outcome: simplified network expansion with reliable throughput, reduced bottlenecks, and plug-and-play deployment for non-IT staff.
For multi-site retail or corporate branches, the SF112-24 provides 24 PoE-capable Fast Ethernet connections (via optional injectors), 2 GE uplinks and 2 Mini-GBIC slots to link IP cameras and DVR servers over fiber. Outcome: centralized video feeds, minimized packet loss, and secure, high-bandwidth transport across demanding surveillance networks.
In academic environments, the Cisco SF112-24 creates isolated VLANs for computer labs, research clusters, and administrative offices. Dual GE uplinks and Mini-GBIC ports aggregate traffic to the campus core switch, ensuring low latency for e-learning and simulation workloads. Outcome: clear traffic isolation, scalable port density, and streamlined network management for IT teams.
When a branch order includes an enclosed equipment rack, mounting and airflow checks belong on the purchase plan. Restricted airflow and uneven mechanical loading must be avoided, and rack-mounted equipment requires reliable grounding. Confirm mounting hardware, grounding provisions, and outlet placement before the PO.
When a lab needs to reproduce an existing large-frame Ethernet segment, the 110 Series supports 9216-byte jumbo frames. Match connected devices and the upstream path to the intended frame size rather than treating switch support as an end-to-end guarantee. Specify test cabling and required endpoint settings before the PO.
PoE power for connected endpoints
SF112-24 provides data connectivity without PoE output. Connected phones, cameras, or access points require separate power; this model cannot replace a switch responsible for powering those endpoints.
Gigabit speed on every access port
SF112-24 limits its 24 access connections to 10/100 Mbps. CBS110-24T-NA provides 24 Gigabit Ethernet ports and is the North American replacement.

SF112-24 identifies a Cisco 110 Series model with 24 Fast Ethernet access ports and two Gigabit combo uplinks. SF112 selects the Fast Ethernet model with Gigabit uplinks; 24 identifies the access-port count. Regional order numbers add a country suffix, including SF112-24-NA for North America.
The Cisco 110 Series operates without configuration: connect power and network cables, and traffic handling starts automatically. Port speed and duplex are negotiated without administrator setup. Automatic cable detection, loop detection, and cable diagnostics handle basic connection checks; deployment does not require an administrator to build a configuration.
SF112-24 is discontinued; SF112-24-NA reached end of sale on October 30, 2021, with Cisco support ending October 31, 2026. CBS110-24T-NA is the North American replacement. Match regional order numbers when comparing stock because lifecycle milestones apply to specific regional variants rather than an interchangeable unsuffixed purchasing code.
ORM offers SF112-24 new sealed with up to a 3-year extended warranty, or certified refurbished with up to a 1-year warranty. Cisco's limited lifetime hardware warranty for SF112-24-NA is bounded by October 31, 2026. Both ORM conditions include 30-day returns; terms apply. Refurbished units are inspected and bench-tested.
No, SF112-24 does not supply PoE to connected devices. Phones, access points, or cameras connected to its access ports require another power source. The switch itself uses its internal AC supply, so an order for data connectivity does not also provide endpoint power or PoE-powered operation.
SF112-24 has two shared Gigabit uplink connections; each combines an RJ-45 interface with a mini-GBIC slot rather than providing two independent links. Copper and fiber can serve different uplink pairs, but both interfaces within one shared pair cannot operate as separate links. Specify the intended medium for each uplink.
Yes, SF112-24 uses a 440 mm-wide, 44 mm-high chassis suitable for a 1U rack installation, with a depth of 203 mm. Mounting hardware is included in the original package; confirm its inclusion when specifying refurbished stock. Rack installations must maintain airflow and reliable grounding.
SF112-24 uses an internal universal AC power supply accepting 110-240V AC at 50-60 Hz. A power cord connects the rear inlet to mains power; an external desktop adapter is not required. Specify the regional mains cord in the order contents so the delivered unit matches the installation location.
SG110-24HP supplies PoE on 12 ports with a shared 100W budget, while SF112-24 does not supply endpoint power. SG110-24HP is also discontinued. The former describes a powered legacy installation; the latter fits an existing installation where connected endpoints already have their own power sources.
SF110D-16 uses an external 12V DC adapter, whereas SF112-24 has an internal AC supply. The external-adapter model requires an adapter in the order contents; the internal-supply model requires the correct regional mains cord. That distinction separates desktop-adapter replacement work from installations standardized on direct AC input.
CBS110-24T-NA provides 24 Gigabit Ethernet ports, whereas SF112-24 provides 24 Fast Ethernet access ports. CBS110-24T-NA is the North American replacement and suits replacement orders requiring Gigabit endpoint links. SF112-24 fits an existing 10/100 installation whose endpoint-speed requirement has not changed.
