The QSW-2104-2S is an easy-to-use unmanaged switch with 2-port 10GbE SFP+ and 4-port 2.5GbE RJ45, allowing you to upgrade your network environment by connecting a wider range of devices with different bandwidth requirements. Featuring a near-silent fanless design and compliance with IEEE 802.3az (Energy Efficient Ethernet, EEE), the QSW-2104-2S operates quietly and with optimal power usage. With high performance and superb functionality, the QSW-2104-2S is the ideal choice for creating an affordable high-speed network environment in your home or workplace.



10GbESFP+ ports

Two 10GbE SFP+ ports (supports 10G/1G) enable high-speed network performance.

2.5GbE ports

Four 2.5GbE RJ45 (2.5G/1G/100M) ports can immediately multiply your network speed by 2.5 times using existing Cat 5e cables.

Plug and play icon

No complex settings are required, and auto-negotiation ensures optimal performance.

loop detection and blocking icon

Automatic loop detection and blocking to ensure continuous network operation.


The unique fanless design with ventilated construction provides noiseless operation.

Energy Efficient

IEEE 802.3az (EEE) helps to reduce power consumption for low-speed and inactive connections.


Maximum flexibility with multiple 10G and 2.5G Ethernet ports

The QSW-2104-2S features 10GbE SFP+ and 2.5GbE RJ45 ports for connecting various bandwidth-demanding devices. With SFP+ interfaces, direct attach copper (DAC) cables can be used for connecting directly to SFP+ devices. With the QSW-2104-2S, you can easily create a hybrid high-speed network in homes and offices to accelerate file transfer, virtual machine applications, multimedia streaming/sharing, and more.

Loop detection and blocking

The QSW-2104-2S features network loop detection. If a network loop is detected, the QSW-2104-2S automatically locks the looped ports to ensure the network environment quickly resumes normal operation.

Near-silent and energy saving

The QSW-2104-2S features a fanless design for near-silent operation. The unique ventilated construction assists in cooling without disrupting your quiet environment while maintaining high performance. IEEE 802.3az (EEE) support also reduces power consumption without sacrificing performance or functionality.
