SG100D-08-UK

SG100D-08-UK is an unmanaged Layer 2 desktop switch with eight 10/100/1000 copper Ethernet ports for small-business networks. Its fixed connections accommodate office endpoints and the connection toward the rest of the network, without a dedicated optical or higher-speed uplink. Computers, printers, and other independently powered equipment can connect without PoE hardware. Cisco 100 Series Unmanaged Switches provide basic office connectivity, and this desktop model belongs to the Cisco Small Business family. The discontinued SG100D-08P-UK is the PoE-equipped sibling. The data-only configuration suits an existing installation where endpoint power is already provided and the requirement is to retain ordinary copper Gigabit Ethernet connections rather than introduce a different switching architecture.

16 Gbps switching capacity provides the internal bandwidth for the Ethernet connections. 11.9 Mpps forwarding handles traffic measured with 64-byte packets, while store-and-forward switching prevents damaged packets from being passed onward. Four hardware queues support priority queuing and weighted round-robin scheduling, with 802.1p priority handling for delay-sensitive traffic. SG100D-08-UK automatically negotiates connection speed and duplex and detects MDI/MDI-X cable arrangements, avoiding manual selection of those connection settings. Energy Efficient Ethernet puts an active link into a sleep state during quiet periods to reduce energy use. An external adapter supplies 12V DC at 1A, keeping the electrical power connection separate from the Ethernet cabling. The operating range is 0°C to 40°C, which bounds placement in an office or equipment area; operating humidity must remain between 10% and 90% and noncondensing.

ORM Systems offers SG100D-08-UK new sealed or certified refurbished; refurbished units are inspected and bench-tested, with power-on checks, every port linking at rated speed, and verification that the supplied adapter delivers rated output. Specify the required condition, quantity, and regional power connection on the purchase order. ORM's new units carry up to a 3-year extended warranty and certified refurbished units up to 1 year, with 30-day returns on every condition, terms apply; Cisco's limited lifetime hardware warranty and 1-year power-supply coverage have ended with retirement. Enterprise and volume purchases can use accepted POs, with Net-30 for government.
