SF102-24 combines 24 Fast Ethernet access ports with two Gigabit combo uplinks in an unmanaged Layer 2 switch. Each uplink offers a copper connection or an SFP connection, with one interface active at a time. The access ports carry data without supplying PoE, so connected equipment needs its own power. The full-width 1U chassis belongs to the Cisco Small Business 100 family and serves basic office connectivity for computers, printers, and other network equipment. The discontinued SF100-24 provides the same Fast Ethernet access density but lacks the Gigabit combo uplinks. The distinction matters when retaining an existing upstream copper or fiber connection.

8.8 Gbps switching capacity accommodates the switch's access and uplink interfaces, while 6.5 Mpps forwarding performance provides a separate packet-processing figure based on 64-byte packets. Automatic speed and duplex negotiation establish compatible copper links without port configuration. SF102-24 uses store-and-forward switching to prevent damaged packets from passing through the network. Four hardware queues support traffic prioritization through priority queuing and weighted round-robin scheduling. Class-of-service handling follows 802.1p priorities, while head-of-line blocking prevention addresses contention between traffic flows. Automatic MDI/MDI-X handles copper cable orientation. The 100 Series Unmanaged Switches operate without configuration; this model does not provide configurable Layer 3 forwarding or hardware stacking.
ORM Systems offers SF102-24 new sealed and certified refurbished. Refurbished units are inspected and bench-tested for power-on and POST, every port linking at rated speed, clean boot, and optics bay recognition. Specify condition, quantities, and required accessories on the purchase order; new units carry up to a 3-year extended warranty, certified refurbished units carry up to 1 year, and every condition includes 30-day returns with terms applying, while Cisco service has ended. Enterprise and volume orders are accepted by PO, with Net-30 for government, RMA with advance replacement, and regional stock and RMA coverage across the UK, EU, US, and MEA.

An office cabling rollout connecting existing computers and printers can retain Category 5 or better cabling for Fast Ethernet connections. Separate endpoint power remains part of the installation plan. Before the purchase order, specify cable quantities, upstream connection media, and the mounting hardware required for each installation location.
A staging bench evaluating larger Ethernet frames can use the switch's 9216-byte jumbo-frame support. Frame-size compatibility must also be checked on the connected equipment and upstream path before staging results are accepted. Specify the intended frame size and include compatible test endpoints in the staging plan before ordering hardware.
Gigabit speeds on every endpoint
SF102-24 access ports stop at 100 Mbps. CBS110-24T-NA provides 24 Gigabit ports, including two shared SFP connections, rather than this model's 26 total connections.
Ethernet power for connected endpoints
SF102-24 does not supply PoE to connected equipment. Endpoints requiring Ethernet-delivered power need a separate power arrangement or a switch with powered ports.
10G upstream network connections
SF102-24 has fixed Gigabit combo uplinks, not 10G uplinks. A requirement for faster upstream connections calls for a different switch with the required interfaces.
Configurable Layer 3 access forwarding
SF102-24 performs unmanaged Layer 2 switching rather than configurable Layer 3 forwarding. Networks requiring routing policies need a managed routing-capable switch instead.

SF102-24 identifies an unmanaged Fast Ethernet switch with 24 access ports and two Gigabit combo uplinks. SF102 is the model identifier, while 24 denotes the access-port count. The complete part number selects the rack-mount configuration with shared copper and SFP uplink interfaces.
SF102-24 operates without configuration: connect the network cables and apply power to begin switching traffic. Copper ports negotiate speed and duplex automatically, and traffic-handling functions operate automatically. Installation planning therefore focuses on physical connections, endpoint compatibility, and upstream requirements rather than preparing switch settings.
SF102-24 is retired, and Cisco service has ended for the Small Business 100 unmanaged family. CBS110-24T-NA is the current migration option, providing unmanaged Gigabit connectivity with two shared SFP connections. Purchase decisions should distinguish like-for-like replacement hardware from a refresh to the current model.
ORM offers SF102-24 new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for refurbished units. Both conditions include 30-day returns; terms apply. Cisco originally provided Limited Lifetime hardware coverage with 1-year fan and power-supply coverage, but Cisco service has ended.
SF102-24 does not supply PoE to connected devices; its Ethernet connections carry data without endpoint power. Phones, access points, cameras, or other equipment needing power must use a separate power arrangement. Include those endpoint power requirements in the purchase order rather than treating this model as a powered switch.
SF102-24 can use two Gigabit uplink connections, each through copper or an SFP slot. Each combo pair permits only one interface to be active at a time, so the copper connector and corresponding SFP slot do not create separate simultaneous connections. Specify the intended media for each uplink before ordering.
The Small Business 100 family supports transceiver options including MGBSX1 and MGBLX1 for Gigabit optical connections. MGBLX1 supports single-mode fiber links to 10 km. Select the optical part to match the fiber connection and include the required transceiver quantities and compatible patching separately from the switch.
SF102-24 is a full-width 1U rack-mount switch with a chassis width of 440.6 mm. Its height is 44.32 mm and depth is 202.82 mm. Confirm that the order includes the mounting hardware required for the installation, and allow space for connected cables before assigning the rack position.
SF102-24 provides 8.8 Gbps switching capacity and a 6.5 Mpps forwarding rate measured with 64-byte packets. These describe different performance characteristics and should be considered alongside the interface speeds. Access connections remain Fast Ethernet, while the two combo uplinks provide Gigabit connections to upstream equipment.
SF100D-16P supplies PoE on eight ports with a shared 64W budget, whereas SF102-24 does not provide endpoint power. SF100D-16P has 16 Fast Ethernet ports rather than 24. Both models are retired; the former fits legacy powered-endpoint requirements, while the latter fits like-for-like replacement needs without PoE.
SF102-24 adds two Gigabit combo uplinks to its 24 Fast Ethernet access ports, while SF100-24 provides 24 Fast Ethernet ports without those uplinks. Both models are retired. SF102-24 fits legacy installations retaining Gigabit copper or fiber upstream connections; SF100-24 fits replacement requirements limited to Fast Ethernet connections.
CBS110-24T-NA provides Gigabit Ethernet across 24 ports, while SF102-24 uses Fast Ethernet access ports with two additional Gigabit combo uplinks. CBS110-24T-NA includes two SFP connections shared with copper ports. The retired SF102-24 fits like-for-like sparing, while CBS110-24T-NA suits buyers refreshing endpoint connections to Gigabit Ethernet.
