## Long description

The QSW-2104-2S is an unmanaged switch that provides 2 x 10GbE SFP+ ports and 4 x 2.5GbE RJ45 ports, enabling a flexible upgrade path for home or office networks with mixed bandwidth needs. Built with a fanless, near-silent design and compliant with IEEE 802.3az (Energy Efficient Ethernet), the QSW-2104-2S combines high performance with low power consumption and straightforward deployment.
Advantages
The QSW-2104-2S supports both SFP+ and multi-gig RJ45 connections, allowing connection of 10G devices and 2.5G-capable equipment without complicated configuration. Its fanless casing and ventilated construction ensure quiet operation while IEEE 802.3az support reduces energy use. Auto-negotiation simplifies setup by selecting optimal link speeds per device, and built-in loop detection locks looped ports to help restore normal network operation quickly.
Suitable for
Home networks requiring faster file transfers and multimedia streaming
Small office networks connecting NAS, workstations, and 10G uplinks
Hybrid environments mixing SFP+ fiber/DAC links and copper devices
Environments where quiet, fanless operation is preferred

How to use
Connect the QSW-2104-2S to your devices using SFP+ modules or DAC cables for 10GbE links and standard RJ45 cables for 2.5GbE connections. Apply power via the 12V DC input and allow the switch to perform auto-negotiation to establish optimal link speeds. No additional configuration is required for basic operation—simply plug devices in and the switch forwards traffic between ports.
Usage recommendations
Place the switch in a well-ventilated location to support passive cooling. For best performance, use appropriate SFP+ modules or DAC cables for 10GbE connections and quality shielded Cat5e/Cat6A/Cat7 cables for 2.5GbE links. Monitor for loop conditions when adding new cabling and use the switch’s loop detection feature to isolate any accidental loops.
