SG102-24-EU is a compact, unmanaged Layer 2 Gigabit Ethernet switch for small-business office connectivity. Its fixed connection layout combines 22 dedicated 10/100/1000 RJ-45 ports with two Gigabit copper/SFP combo positions, with only one medium active per combo position. The Small Business 100 model connects computers, printers and other office equipment without switch configuration. Endpoint power must come from a separate source because the connections do not supply PoE. The discontinued SG100D-08P provides PoE output but reduces the total connection count to eight. The compact 24-port Gigabit switch addresses basic local connectivity in a desktop-sized enclosure rather than a purchase dependent on configurable network policies.

48 Gbps switching capacity sets the aggregate switching ceiling, while 35.7 Mpps forwarding capacity describes packet handling with 64-byte frames. Store-and-forward operation identifies damaged packets before passing traffic onward. Four hardware queues separate priority levels, with priority queuing and weighted round-robin scheduling handling traffic according to 802.1p class of service. Jumbo frames of 9216 bytes are supported, alongside head-of-line blocking prevention. SG102-24-EU uses automatic MDI/MDI-X and port autonegotiation to establish compatible Ethernet links without manual crossover selection. Energy Efficient Ethernet reduces active-link energy use during quiet periods. The internal universal AC supply accepts 100–240V AC at 50–60 Hz, requiring an appropriate AC feed rather than an external adapter. Operating limits of 0°C to 40°C constrain the equipment location and should be checked before installation. There are no 10G connections.
ORM Systems offers SG102-24-EU new sealed or certified refurbished, with up to a 3-year extended warranty for new units and up to 1 year for certified refurbished units. Refurbished units are inspected and bench-tested for power-on and POST, rated-speed links on every port, clean boot, optics bay recognition and internal PSU status. Specify the condition, quantities and a power cord appropriate for the receiving site's AC connection on the purchase order; 30-day returns apply to every condition, terms apply. Enterprise and volume buyers can place quantities on an accepted PO, with Net-30 available for government orders.

When an office expansion reuses existing copper cabling, SG102-24-EU selection depends on the cable plant as well as the switch. Category 5 Ethernet cabling is the minimum requirement. Audit the installed runs and include any replacement patch leads needed for the receiving location before issuing the purchase order.
Where purchasing covers sites in the UK, EU, US or MEA, replacement handling can be specified alongside the hardware rather than left to each location. ORM Systems provides regional stock and RMA across these regions. Identify the receiving region, site quantities and advance-replacement requirements on the purchase order.
Power delivery to connected endpoints
SG102-24-EU provides no PoE output. Phones, cameras and access points requiring Ethernet power need a PoE-capable connection or a separate endpoint power source.
10G connections to upstream equipment
SG102-24-EU limits copper and shared SFP connections to Gigabit Ethernet. An upstream connection requiring 10G cannot operate at that speed through these ports.

SG102-24-EU identifies a regional version of the compact 24-port Gigabit switch with two combo mini-GBIC connections. SG102 identifies the compact Gigabit model, 24 denotes the total logical port count, and EU is the regional ordering suffix. The connections comprise 22 dedicated copper ports and two shared copper/SFP positions.
SG102-24-EU operates without configuration: connect power and attach the Ethernet devices. Port speed and duplex are selected automatically, and traffic handling runs without a setup process. The unmanaged design addresses a fixed-connectivity requirement rather than a purchase that depends on configurable switch behavior.
SG102-24-EU is discontinued and belongs to the retired Small Business 100 series. Its first replacement, SG112-24-EU, is also discontinued; CBS110-24T-EU is the next model in that replacement chain. An order for the older part should identify the required condition and replacement handling explicitly.
SG102-24-EU is available from ORM Systems new sealed or certified refurbished, with up to a 3-year extended warranty on new units and up to 1 year on refurbished units. Every condition includes 30-day returns; terms apply. Cisco's original limited lifetime hardware warranty is separate, and the series is retired.
No, SG102-24-EU does not supply PoE power to connected devices. Its Ethernet connections carry data, so a phone, camera or wireless access point must receive power from another source. Specify endpoint power separately rather than treating the available Ethernet connections as powered ports.
SG102-24-EU accepts Gigabit SFP options including MGBSX1 and MGBLX1 in its two combo connections. MGBSX1 provides SX connectivity, while MGBLX1 provides LX connectivity for single-mode fiber. Choose the optic by cable type and reach, and remember that each SFP connection shares its corresponding copper connection.
SG100D-08P provides PoE on four ports, while SG102-24-EU provides no PoE output. SG100D-08P is also an eight-port desktop model, so the power difference comes with fewer connections. Both belong to the discontinued 100 series; the smaller model addresses powered endpoints, while SG102-24-EU addresses greater connection density without PoE.
SG102-24-EU takes AC directly through an internal supply, whereas SG100D-08 requires an external DC adapter. Both are discontinued 100 series models. SG102-24-EU addresses installations that avoid a separate adapter; SG100D-08 is an eight-port desktop model whose purchase must include an adapter supplying 12V DC at 1A.
SG102-24-EU provides 24 logical Gigabit connections, while SG100-16 provides 16 Gigabit copper connections. Both are discontinued models from the 100 series. The larger connection count addresses a more populated installation; SG100-16 addresses installations that need fewer connections and do not require the combo fiber positions.
SG102-24-EU occupies an enclosure measuring 279.4 mm wide, 44.5 mm high and 170 mm deep, with a weight of 2.3 kg. Mounting hardware was included in the original package. Check the mounting arrangement and supplied hardware on the specific order rather than assuming a full-width chassis.
SG102-24-EU supports 48 Gbps switching capacity and 35.7 Mpps forwarding with 64-byte packets. These are switching and packet-forwarding limits, not a faster uplink speed. Every active connection remains Gigabit Ethernet, so size upstream traffic around the actual connection speed rather than the aggregate capacity.
The Small Business 100 series uses four hardware queues with priority queuing and weighted round-robin scheduling. Its class-of-service handling follows 802.1p priority, and these traffic-handling functions run automatically. The configuration-free behavior addresses requirements that do not depend on custom traffic policies or manually adjusted queue settings.
SG102-24-EU automatically negotiates compatible port speeds and duplex settings for attached Ethernet devices. Automatic MDI/MDI-X handles cable crossover selection, while Energy Efficient Ethernet reduces energy use during quiet link periods. These functions operate automatically, so the purchase does not depend on configuring individual port settings.
Yes, the Small Business 100 series supports jumbo frames of 9216 bytes. Store-and-forward switching identifies damaged packets, and head-of-line blocking prevention is included. Jumbo-frame support does not change the Gigabit connection speed; connected equipment must also accept the intended frame size for an end-to-end jumbo-frame path.
