Copper Network Connections for Small Office Equipment
SG100D-05-UK is an unmanaged Layer 2 desktop switch with five 10/100/1000 RJ-45 ports for small-business Ethernet connections. The Cisco 100 Series model uses fixed copper interfaces rather than an uplink module bay and has no fiber slot. Computers, printers and copiers connect as separately powered endpoints because this model supplies no PoE output. The discontinued SG100D-08P differs by providing four powered connections within its eight-port configuration. The Cisco Small Business range places this hardware in basic office networks where switching operates without configuration. An upstream network connection occupies an ordinary Ethernet port, so the endpoint count must allow for that link rather than assuming an additional dedicated uplink.

Technical Details
10 Gbps switching capacity supports traffic across the connected equipment, while 7.4 Mpps forwarding performance applies to 64-byte packets. Four hardware queues handle traffic priority through priority queuing and weighted round-robin scheduling, with 802.1p class-of-service markings providing the priority input. SG100D-05-UK uses store-and-forward switching to identify damaged packets before passing them through the network, and head-of-line blocking prevention addresses blocked traffic queues. 9216-byte jumbo-frame support accommodates larger Ethernet frames when attached equipment uses compatible settings. Energy Efficient Ethernet monitors active-link traffic and places links into a sleep state during quiet periods. IEEE 802.3x flow control provides another automatic traffic-handling function. These capabilities operate without user configuration; they do not change the unit's unmanaged operation or provide a configurable switching role.
Ordering
ORM Systems supplies SG100D-05-UK new sealed or certified refurbished; refurbished units are inspected and bench-tested, including every port linking at rated speed and verification that the supplied adapter delivers rated output. Specify the condition and adapter requirement on the purchase order. ORM provides up to a 3-year extended warranty for new units, up to 1 year for certified refurbished units, and 30-day returns on every condition, terms apply; Cisco's limited lifetime hardware coverage ended with service on December 31, 2020. PO accepted, Net-30 for government and RMA with advance replacement are available for enterprise and volume orders.

Best For
Office Connection Expansion
Where an office needs network connections away from a cabinet, SG100D-05-UK can use the wall-mounting option available to the desktop models. Positioning beneath a desk or on an office wall requires suitable attachment hardware. Specify the mounting hardware and Ethernet patch leads before issuing the purchase order.
Bench Staging
During bench staging, SG100D-05-UK automatically selects port speed and duplex and detects MDI or MDI-X cable connections. That behavior supports equipment checks without a configuration step. Include the required Ethernet leads in the order, then confirm negotiated links with the actual equipment before releasing the staged assembly.
Installed Base Sparing
An installed-base spares request for SG100D-05-UK can distinguish an exact-part replacement from a migration purchase. ORM offers new sealed and certified refurbished conditions, with RMA and advance replacement available. Put the required condition, original part number and replacement handling on the purchase order before approving a substitution.
Not Suitable If
Switch-powered phones or access points
SG100D-05-UK supplies no PoE output. CBS110-8PP-D-UK is a partial-PoE alternative in the replacement path, but increases the connection count from five to eight ports.
Fiber connections to upstream equipment
SG100D-05-UK has no SFP slot. CBS110-24T-UK provides two shared 1G SFP connections, but increases the port count to 24 rather than retaining the five-port arrangement.

Questions & Answers
What does the SG100D-05-UK part number mean?
SG100D-05-UK identifies a Cisco 100 Series Gigabit desktop switch with five ports. The SG100 portion identifies the Gigabit 100 Series model, D denotes desktop, and 05 denotes five ports. Keep the UK ordering suffix intact when matching an existing purchase record or specifying an exact-part replacement.
How is SG100D-05-UK managed?
SG100D-05-UK operates without configuration: connect its power adapter and network cables to begin switching traffic. Port speed and duplex are selected automatically, while traffic-priority functions operate without user setup. The unmanaged operation is intended for basic network connectivity rather than an installation requiring configurable switching behavior.
Is SG100D-05-UK discontinued?
Yes, SG100D-05-UK belongs to a discontinued range whose end-of-sale date was December 9, 2015, and whose Cisco support ended December 31, 2020. A new sealed unit does not restart those lifecycle dates. A migration purchase should follow the replacement path through to CBS110-5T-D-UK.
What condition and warranty does ORM offer for SG100D-05-UK?
SG100D-05-UK is offered new sealed or certified refurbished, with ORM warranties of up to a 3-year extended term for new units and up to 1 year for refurbished units. Returns are 30 days on every condition, terms apply. Cisco's former limited lifetime hardware warranty ended with support on December 31, 2020.
Does SG100D-05-UK provide PoE?
No, SG100D-05-UK does not provide PoE output on its Ethernet ports. Connected phones, cameras and access points therefore need their own power arrangement. The external adapter powers the switch itself; it does not create an endpoint power budget across the copper connections.
Which uplinks does SG100D-05-UK have?
SG100D-05-UK has no dedicated uplink port or SFP cage; an upstream connection uses one of its existing Gigabit copper ports. No removable network module adds fiber connectivity to this model. Include the upstream connection when determining how many ports remain for locally connected equipment.
What switching performance does SG100D-05-UK provide?
SG100D-05-UK provides 10 Gbps switching capacity and a 7.4 Mpps forwarding rate for 64-byte packets. These figures describe different aspects of packet handling and are not an individual port's speed. Jumbo-frame support reaches 9216 bytes when the connected equipment uses compatible frame settings.
What power adapter does SG100D-05-UK require?
SG100D-05-UK uses a 12V DC, 1A input supplied through an external power adapter. The adapter is part of the original package, so a replacement or refurbished order should explicitly include a matching adapter. Plan space for both the enclosure and its external power connection.
What is the difference between SG100D-05-UK and SG100D-08P?
SG100D-08P supplies PoE on four ports with a 33.6W shared budget, whereas SG100D-05-UK has no powered ports. SG100D-08P is discontinued, so this is an installed-base comparison rather than a current-model recommendation. The former fits powered-endpoint requirements; the latter fits separately powered office equipment.
What is the difference between SG100D-05-UK and SG100-16?
SG100-16 has an internal 100-240V AC power supply, whereas SG100D-05-UK uses an external adapter feeding a 12V DC input. SG100-16 is also discontinued. The internal-supply model fits an existing direct-mains installation; the external-adapter model fits a replacement purchase retaining that separate power arrangement.
What is the difference between SG100D-05-UK and CBS110-5T-D-UK?
CBS110-5T-D-UK is the later five-port Gigabit replacement reached through the migration chain, while SG100D-05-UK is retired and Cisco service has ended. The intermediate SG110D-05-UK is discontinued. CBS110-5T-D-UK fits a migration order; SG100D-05-UK fits an exact-part spares request for an existing installation.
Is the five-port Cisco 100 Series switch rack-mountable?
The five-port Cisco 100 Series model is a desktop switch, not a full-width rack-mount chassis. Its enclosure measures 110 mm wide, 30 mm high and 100 mm deep, with a weight of 0.32 kg. Desktop models also offer wall mounting; confirm the mounting hardware required for the intended location.
