QNAP Systems, Inc., a leading computing, networking and storage solution innovator, today launched the eight-port 2.5GbE unmanaged switch - the QSW-1108-8T. Featuring eight 2.5GbE ports, plug-and-play set up, automatic loop detection and blocking, and auto-negotiation functions, the QSW-1108-8T is a cost-efficient high speed network upgrade solution for homes and businesses.

"One of the major elements holding back people from upgrading their Ethernet infrastructure is the cost and availability of switches and adapters. QNAP have demonstrated a firm commitment to the 2.5GbE ecosystem, with the new QSW-1108-8T switch representing an affordable way for home and business users to take their Ethernet network to the next level," said Ricky Ho, Product Manager of QNAP.
 
The QSW-1108-8T features eight 2.5GbE/NBASE-T RJ45 ports that support 2.5G/ 1G/ 100M transfer speeds. With no complex settings required, the QSW-1108-8T supports auto-negotiation that optimizes transfer speeds and performance for each connected device, while its built-in management mechanism ensures smooth transmission of network packets. It also features network loop detection that can automatically lock looped ports to ensure the network environment quickly resumes normal operation.

The QSW-1108-8T features a fanless design for near-silent operation. The unique ventilated construction assists in cooling while maintaining high performance.

The QSW-1108-8T network switch is now available.
 
Sadly I couldn't get pricing. QNAP seems to have made a very good high speed network switch which should be a good solution for a home business.
