SF112-24-UK combines fanless operation with 24 Fast Ethernet access ports and two fixed Gigabit combo uplinks for copper or fiber connections. This unmanaged Layer 2 switch serves independently powered computers, printers, copiers, and other office equipment; its Ethernet ports do not supply PoE. The rack-mount 1U chassis belongs to the Cisco 110 Series Unmanaged Switches family, which provides basic connectivity without configuration. Each combo uplink shares its copper connection with an SFP slot, so the connection uses one medium at a time. Compared with the discontinued SF110-24-AR, this model adds Gigabit uplinks rather than limiting every connection to Fast Ethernet. The access connections remain 10/100 Mbps regardless of the selected uplink medium.

8.8 Gbps switching capacity accommodates traffic across the access and uplink interfaces. 6.5 Mpps forwarding performance characterizes packet handling with 64-byte packets, providing a separate measure from aggregate switching bandwidth. Four hardware queues support 802.1p priority handling, with priority queuing and Weighted Round-Robin scheduling for traffic treatment. Store-and-forward switching prevents damaged packets from continuing through the network, while head-of-line blocking prevention addresses queue interference. SF112-24-UK uses automatic MDI/MDI-X detection and port autonegotiation to establish supported connection settings without manual setup. Automatic loop detection helps identify accidentally created network loops, and cable diagnostics identify cable faults or shorts. These functions operate automatically rather than through an administrator-defined configuration. The internal universal AC supply accepts 110-240V AC, allowing the electrical input requirements to be checked separately from the regional power-cord requirement.
SF112-24-UK is offered new sealed or certified refurbished; ORM's warranty is up to a 3-year extended term for new units and up to 1 year for certified refurbished units, while Cisco's original limited lifetime hardware warranty and service ended August 31, 2024. 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. Specify condition, required mounting hardware, and power cord on the PO; returns cover every condition for 30 days, with terms applying. For enterprise and volume orders, PO acceptance, Net-30 for government, and RMA with advance replacement are available.

When a replacement program spans offices using the UK ordering region, the suffix covers the United Kingdom, Saudi Arabia, Qatar, and Kuwait. Keep the complete regional part number on the requisition rather than substituting an unsuffixed name, and confirm the required power cord before releasing the PO.
When a staging bench must reproduce an existing Ethernet segment, jumbo-frame handling reaches 9216 bytes. Validate the connected devices' frame settings before moving the spare into service; matching a switch part number alone does not establish end-to-end jumbo-frame operation. Put the required frame size on the purchase specification.
Gigabit speed on every access connection
The 24 access ports operate at 10/100 Mbps; Gigabit speed is confined to the two combo uplinks. A requirement for Gigabit endpoint connections exceeds this configuration.
Ethernet power for attached endpoints
The access ports do not supply PoE. Phones, cameras, or access points that require Ethernet-delivered power need a separate power arrangement rather than a direct powered connection.

SF112-24-UK combines the SF112 Fast Ethernet model designation, 24 access ports, and the UK regional ordering suffix. The UK suffix covers the United Kingdom, Saudi Arabia, Qatar, and Kuwait. The hardware configuration includes two Gigabit combo uplinks rather than Gigabit speed on the access ports.
SF112-24-UK operates without configuration: connect power and Ethernet devices, and switching starts automatically. Each port negotiates its supported speed and duplex setting. Automatic traffic prioritization, loop detection, and cable diagnostics operate without a setup workflow, so deployment centers on the physical connections rather than administrator-defined switch settings.
SF112-24-UK is discontinued: end of sale was August 12, 2019, and Cisco service ended August 31, 2024. The final shipment milestone was November 10, 2019. No direct replacement was designated for this regional part number, so a migration must be specified separately rather than assumed equivalent.
SF112-24-UK has two fixed Gigabit combo uplinks, each sharing one copper connection with one SFP slot. Choose the copper or fiber side of each combo connection; both sides are not independent ports. These uplinks do not raise the speed of the Fast Ethernet access connections.
SF112-24-UK does not supply PoE to attached devices, so phones, cameras, or access points need a separate power arrangement. The internal AC supply powers the switch itself rather than connected endpoints. Include endpoint power requirements in the purchase specification instead of treating an Ethernet connection as a power source.
The Cisco SF112-24 uses a rack-mount 1U chassis measuring 440 mm wide, 203 mm deep, and 44 mm high, with a weight of 1.93 kg. Mounting hardware belongs in the original package. Confirm the mounting hardware and power cord on the order rather than assuming previous accessories fit.
SF110D-16HP-AU provides PoE on eight ports with a shared 64W budget, whereas SF112-24-UK supplies no endpoint power. Both models are discontinued, making this a legacy compatibility comparison rather than a current migration recommendation. The powered model serves PoE-dependent connections; the unpowered model serves separately powered equipment.
SF112-24-UK adds two Gigabit combo uplinks, while SF110-24-AR provides Fast Ethernet connections without Gigabit uplinks. Both models are discontinued. The former accommodates a faster upstream connection; the latter matches an existing all-Fast-Ethernet layout when comparing legacy equipment rather than selecting a current successor.
SF112-24-UK provides 24 Fast Ethernet access ports, while SF110-16-UK provides 16. Both models are discontinued. When matching existing equipment rather than choosing a current successor, the higher-density unit accommodates more endpoint connections; the smaller unit corresponds to installations requiring fewer access connections.
ORM Systems offers SF112-24-UK new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Returns cover every condition for 30 days; terms apply. Cisco's original limited lifetime hardware warranty ended with Cisco service on August 31, 2024.
