SF102-24-UK is an unmanaged Layer 2 switch with 24 Fast Ethernet access ports and two fixed Gigabit combo uplinks. Each uplink provides an RJ-45 connector and an SFP slot, with one connection active per pair. The rack-mount chassis occupies 1U and connects computers, printers, copiers, and other office equipment. Cisco 100 Series Unmanaged Switches operate without configuration, making this model relevant to retained installations that require basic Ethernet connectivity rather than configurable switching. Access ports do not supply PoE, so connected devices need a separate power source. The discontinued SF100-24 provides the same access-port density without dedicated Gigabit uplinks; this configuration retains faster upstream connections while keeping Fast Ethernet at the endpoint connections.

8.8 Gbps switching capacity accommodates traffic across the access connections and Gigabit uplinks. 6.5 Mpps forwarding performance applies to 64-byte packets, providing a packet-rate reference when assessing an existing traffic profile. SF102-24-UK uses four hardware queues with priority queuing and weighted round-robin scheduling to handle competing traffic. Automatic quality-of-service processing prioritizes delay-sensitive voice and video traffic without an administrator configuring queue policies. Store-and-forward switching identifies damaged packets before passing traffic onward, while head-of-line blocking prevention addresses forwarding contention. The 24-port Fast Ethernet switch with Gigabit combo uplinks supports flow control alongside those automatic traffic-handling functions. An operating range of 0°C to 40°C bounds placement in office and equipment-room environments. The 100 Series therefore requires ambient-temperature checks at the intended installation point rather than assumptions based on room temperature elsewhere in the building.
Order SF102-24-UK from ORM Systems in new sealed or certified refurbished condition, and specify the required condition and connection accessories on the PO. Certified refurbished units are inspected and bench-tested, with power-on and POST checked, every port tested for rated-speed links, a clean boot verified, and optics bay recognition checked. New units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and both conditions include 30-day returns; terms apply. For enterprise purchasing and volume orders, ORM Systems accepts POs, provides Net-30 for government, and offers RMA with advance replacement.

When an office extends an existing copper network, Category 5 or better Ethernet cabling is the starting requirement for attached equipment. Automatic MDI/MDI-X accommodates straight-through and crossover connections. Before issuing the PO, inspect existing cable runs and specify the patch-cord quantities needed for the additional computers, printers, and copiers.
When a staging bench must reproduce traffic from an existing installation, 9216-byte jumbo-frame support provides a specific compatibility point to check against attached equipment. Testing should establish whether the connected devices use matching frame sizes. Specify the required traffic profiles, endpoint combinations, and acceptance checks before ordering equipment for the bench.
Gigabit speeds on every access port
The 24 access ports operate at 10/100 Mbps. Gigabit connectivity is confined to the combo uplinks, so this model cannot provide Gigabit rates to every attached endpoint.
PoE power for attached endpoints
The access ports do not supply PoE. Phones, cameras, and wireless access points requiring power through their Ethernet connection cannot receive that power from this model.
Simultaneous copper and fiber per uplink
Each combo uplink activates either its RJ-45 connector or its SFP slot, not both. Fiber therefore occupies the corresponding shared uplink rather than adding an independent connection.

SF102-24-UK identifies a Cisco 100 Series unmanaged switch with 24 Fast Ethernet access ports and Gigabit uplinks. SF102-24 is the hardware model designation, and 24 corresponds to the access-port count. Retain the complete -UK ending when specifying this regional ordering form.
SF102-24-UK operates without configuration: connect the network equipment and allow the switch to handle Ethernet forwarding automatically. Ports negotiate their connection settings, and automatic cable detection accommodates the connection type. The unmanaged operating model is intended for basic connectivity without an administrator setting up switching policies.
No, SF102-24-UK belongs to the retired 100 Series and is no longer supported by Cisco. Its named replacement, SF112-24-UK, is also discontinued. That replacement reached end of sale on August 12, 2019, and its Cisco support ended on August 31, 2024; no current successor is named for that regional replacement.
ORM Systems offers SF102-24-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 are available for 30 days in either condition; terms apply. Cisco’s original limited lifetime hardware warranty no longer provides coverage because Cisco support has ended.
SF102-24-UK provides 24 Fast Ethernet access connections and two Gigabit combo uplink connections. Each combo uplink has a copper connector and an SFP slot, but only one side operates at a time. Populating both SFP slots therefore does not create two additional connections beyond the two shared uplinks.
No, SF102-24-UK does not supply PoE to connected equipment. Its access connections carry Ethernet data without powering the attached device. Phones, cameras, or wireless access points that depend on Ethernet-delivered power therefore need a separate power arrangement; an available data port alone does not satisfy that requirement.
SF102-24-UK provides 8.8 Gbps switching capacity and a forwarding rate of 6.5 Mpps for 64-byte packets. These figures describe different aspects of traffic handling and should remain separate when comparing equipment. They do not change the Fast Ethernet speed of individual access connections or the Gigabit speed of the uplinks.
SF102-24-UK is a full-width, 1U rack-mount switch measuring 440.6 mm wide, 44.32 mm high, and 202.82 mm deep. Its published weight is 2 kg. Confirm the available rack position, equipment clearance, and mounting hardware included with the selected condition before completing the purchase order.
MGBLX1 is a 1000BASE-LX SFP option for SF102-24-UK, supporting single-mode fiber over distances up to 10 km. A populated SFP slot shares its uplink with the corresponding copper connector. Specify a matching optical connection at the far end rather than assuming every SFP is interchangeable.
SF100D-16P supplies PoE through eight ports using a shared 64W budget, whereas SF102-24-UK supplies no endpoint power. Both are discontinued 100 Series models. SF100D-16P addresses retained installations needing Ethernet-delivered power; SF102-24-UK addresses installations where the attached equipment already has its own power arrangement.
SF102-24-UK includes two Gigabit combo uplinks, whereas SF100-24 provides Fast Ethernet connections without dedicated Gigabit uplinks. Both models are discontinued. SF102-24-UK matches a retained installation that needs Gigabit upstream connectivity; SF100-24 matches an existing layout that requires only Fast Ethernet connections throughout the switch.
SF102-24-UK has 24 Fast Ethernet access ports, while SF100-16 has 16. Both belong to the discontinued 100 Series unmanaged family. SF102-24-UK suits retained installations terminating more endpoint connections; SF100-16 matches an existing installation whose connection requirement remains within the smaller access-port count.
